LUBRICACIÓN DE ENGRANAJES ABIERTOS DE PALAS BUCYRUS El presente documento quiere presentar un resumen de las especificaciones de lubricantes de la empresa Bucyrus International (BI) a lo largo de los últimos años. Nos limitaremos a la lubricación de los sistemas de engranajes abiertos en las palas gigantes. Debemos indicar que la empresa Bucyrus ha cambiado sus especificaciones de lubricantes varias veces a lo largo de los años.

1.- Antes de 1990 La especificación inicial, de la cual no contamos con documento oficial de BI, era emplear una grasa única para toda la pala, es decir que los 6 sistemas A1, A2, B1, B2, C1, C2 empleaban el mismo lubricante. Se trataba básicamente de grasas con aceites base de muy baja viscosidad, que garantizaban que los rodamientos lubricados no se afectasen por la alta viscosidad de las grasas de mejor performance, comúnmente recomendadas en engranajes abiertos. Por los años 90 BI comprende que al emplear un solo lubricante, está sacrificando rendimiento de la grasa y decide cambiar su especificación a recomendar dos grasas para sus palas: la OGL o de engranajes abiertos y la EP para rodamientos. En esa ocasión Bucyrus emite un documento explicando el cambio a dos lubricantes, el que se adjunta como anexo I

2.- Desp Después ués d e 1990 1990 A partir de los años años 90 con la salida salida al mercado de las palas 495 495 B I, las más grandes grandes de la gama, Bucyrus recomendaba ya el empleo de dos grasas. Años más tarde aparece aparece la 495 B II. Las especificaciones especificaciones Bucyrus Bucyrus para los lubricantes lubricantes de engranajes abiertos de estas palas, se muestran a continuación y el documento completo se adjunta a este documento, como anexo II. Estas especificaciones son válidas para las 495 B I, B II, así como para las palas 495 HR hasta el año 2004, pues en Agosto del 2005 se cambian las especificaciones. La especificación es clara y válida para todo lubricante OGL; los de tipo asfáltico residual, semi sintéticos y grasas. Seleccionamos de estas especificaciones, las que en el pasado se emplearon para desaprobar nuestro lubricante Mobiltac. Estas son: Load Weld Copper Strip Corrosion

250 kg. Min pasa

Como se aprecia en la adjunta hoja técnica del Mobiltac 275 (OGL 595 bajo la marca Petron) anexo V, y en el recuadro que publicamos más abajo, nuestro lubricante cumple con estos requisitos, pues tiene t iene Load Weld Copper Strip Cossrosion

400 Kg pasa

También se puede comparar los demás requerimientos y se verá que nuestro lubricante cumple y excede todos éstos.

Mobiltac 275

3.- Desde el año 2005 En agosto del 2005, luego de que algunas nuevas palas 495 HR venían operando ya en el mercado, Bucyrus decide cambiar sus especificaciones de lubricantes en general y por lo tanto se incluye cambios en los OGL. Es de suponer que las mejoras en tamaño del cucharón, potencia de los equipos, velocidad de carga y descarga, entre muchos otros, originó que BI replantee sus especificaciones de lubricantes. La norma técnica respectiva se incluye como adjunto, anexo III y un recuadro resumen se reproduce a continuación. Cabe indicar que la especificación es definida SOLAMENTE para las palas posteriores a esa fecha, agosto del 2005, pues sino Bucyrus habría enviado una nota a todos los Usuarios de equipos antiguos indicando que el cambió de especificaciones afecta a las palas de cada Usuario. Lo que sí ha sucedido en el siguiente cambio de Bucyrus (ver acápite 4)

Es importante analizar los cambios más importantes de esta norma: -

Incluye corrosión al cobre. No comprendemos porque se incluye este valor, ya que los bujes de bronce son casi inexistentes en el caso del circuito de OGL

-

Se incrementa el valor a la carga de soldadura a 800 kg y se aumenta también el diámetro de desgaste a 0.7 mm. Como fabricantes de lubricantes para engranajes abiertos consideramos innecesario este aumento en el valor de soldadura, más aun si este va acompañado de incremento del diámetro de cicatriz permitido. Es decir se admite mayores cicatrices o huellas de una falla de lubricación.

AGMA no considera necesario el valor de carga de soldadura como importante en engranajes abiertos, sino la creación de una película lubricante creada por la alta viscosidad. -

Se incluye viscosidades mínimas para 3 valores de temperatura, aunque los rangos han cambiado con respecto a la norma anterior. Consideramos las viscosidades solicitadas como muy bajas para la protección requerida. El tiempo nos dio la razón, como se verá luego.

Lo importante en analizar esta norma, es que las palas de Alumbrera no están incluidas bajo esta norma. Si lo están en la norma anterior que es la válida para su fecha de fabricación y fue incluida en los manuales recibidos de la pala.

4.- Desde Junio del 2011 Bucyrus, debido a ciertos problemas en los Hoist, decide cambiar la especificación de sus lubricantes, según norma adjunta, como anexo IV. El encabezado de la nueva norma es claro, indica que es obligatorito, inclusive para todas las palas antiguas cuyos número de serie se detalla en la misma.

Como se ve, Bucyrus es claro cuando retroactivamente cambia las especificaciones para palas fabricadas con anterioridad a la emisión de una nueva norma. Igualmente será válida para todas las palas nuevas fabricadas a partir de la fecha. El cuadro resumen de los cambios en las nuevas especificaciones se muestra a continuación. Como se ve solamente se ha incrementado la viscosidad del lubricante para la transmisión del Hoist. Nosotros aun creemos que este incremento es muy bajo. Los engranajes abiertos requieren de la mas alta viscosidad para poder trabajar adecuadamente protegidos y en ese sentido el Mobiltac trabaja con viscosidades tan altas como 60,000 cSt @ 40ºC, donde BI exige solamente 5,000. AGMA es claro al respecto y solicita muy altas viscosidades

Estas nuevas especificaciones no son aplicables a las palas de Alumbrera, pero las incluimos para resaltar el hecho de que los cambios en las normas no son retroactivas, a no ser que expresamente lo indique Bucyrus, aun con número de serie de cada pala involucrada. En consecuencia las palas de Alumbrera deberán lubricarse de acuerdo a las especificaciones incluidas en el manual respectivo y reproducidas en este documento en el acápite 2. De acuerdo a las explicaciones cronológicas brindadas en este documento, todas respaldadas por las normas vigentes de Bucyrus, se conluye que nuestro lubricante Mobiltac es aprobado para lubri car las palas de Minera Alumbr era. Adicionalmente como se les brindó en su momento Alumbrera es libre de contactar a la mina Peruana Antamina para confirma los resultados de empleo del Mobiltac en palas 495 BI de esta mina. Así como de cualquier usuario de la lista de usuarios incluida.

PROHIBICION DE LUBRICANTE UNICO

Single Lubricant Usage on Bucyrus Electric Mining Shovels David M. Lang – Director of Engineering – Shovels and Drills - Bucyrus International Inc. In previous times it had been deemed beneficial by end users, equipment manufacturers, and lube suppliers to consolidate open gear lubricants and greases into one product. A common lubricant that worked equally well in high and low speed bearings, bushings, open gears, dipper handles, and roller circles was thou ght to be advantageous from a supply and distribution standpoint. This concept has not proved to be as practical as originally conceived. · Certain bearing suppliers have never subscribed to the idea. They felt that bearing life was compromised, especially if abrasive extreme pressure additives such as molybdenum were utilized in the compositions. · Lube companies were sometimes forced into a lube selection that compromised performance. It was that or walk away from business. · Some lube companies claimed a single lube product but needed to supply dual versions of that product. (The concept of a single lubricant was only lip service.) The effectiveness of lubrication products in general has been challenged since the elimination of lead based additives. Products have changed composition often resulting in decreased performance. This has further clouded the single lube issue and resulted in reduced success. In order to produce equipment with the greatest universal utility Bucyrus has continued to equip its shovel products with lube systems capable of two distinct systems: Open Gear Lube, and Grease. Piping, injectors, pumps, and reservoirs continue to be capable of accepting two different lube products. With the ever increasing concern for equipment reliability, reduction in downtime, decrease in failure rates, and component longevity it now seems more prudent than ever to reestablish a position on the single lube matter. The use of a single “universal” lubricant is inconsistent with the goal of increased Mean Time Between Failure .

Bucyrus International, Inc. hereby recommends dual lube products to be used on its mining shovel product

Dipper handles, swing rack teeth, rollers and rails, and open gears have been shown to work best with Open Gear lube products. Bearings best function with grease. Bushings can often function either way depending on the individual product.

Bucyrus International, Inc. SPECIFICATION FOR

OGL – OPEN GEAR LUBRICANT

SD4713 (August 18, 2005) SCOPE:

1. This specification covers “Open Gear Lubricant”. 2. Materials furnished under this specification are primarily intended to lubricate open gears, but may also be used to lubricate racks, bushings, rails, rollers, dipper handles and propel mechanism components. 3. The material furnished under this specification must be dispensable through the distribution lines of a centralized lubrication system to the most remote application point, at the lowest anticipated operating temperature. It must not plate or plug components of the centralized lubrication system such as injectors, metering blocks, or spray nozzles. 4. This specification covers open gear lubricants that may be applied in service at temperatures ranging from -50°C (-58°F) to the highest ambient temperature conditions. The particular grade or consistency selected must perform within the specific temperature range in which it is utilized.

PHYSICAL CHARACTERISTICS:

1. Materials furnished under this specification may be asphaltic (bitumen) compounds, or blends of a thickener and mineral oils and/or synthetic fluids. They may be in the form of viscous fluids, semi-fluid greases or pastes. 2. Materials furnished under this specification are produced with highly fortified blends of viscous fluids combined with additives to form stable, long lasting, high load carrying, wear resistant films that lubricate under mixed film and boundary conditions. 3. Open gear lubricants supplied under this specification must have excellent adhesive and cohesive qualities, must not chip or throw off, and must provide sufficient film thickness and scuffing resistance to prevent metal to metal contact between applications under all operating conditions. 4. Various grades or consistencies of open gear lubricants may be required to provide proper lubrication and application properties over a wide range of ambient temperatures. The consistency of the lubricant as applied must be appropriate for the method of application, and the in-service consistency shall be appropriate for the lubricant to meet or exceed the minimum performance requirements listed in the "MINIMUM PERFORMANCE REQUIREMENTS" section.

Page 1 of 4



SD4713 (August 18, 2005) 5. Viscosity, a fluid's resistance to flow, is the principal physical characteristic of a fluid in terms of its ability to produce a lubricating film between two interfacing surfaces. All lubricating fluids possess a natural viscosity that may be altered (enhanced) by additives such as resins or polymers. Some "viscosity enhancers" are shear sensitive, which could result in insufficient protection of the lubricated components under high load, elevated temperatures and/or high shear conditions. The viscosity of the fluids utilized in the open gear lubricants shall be sufficient under operating conditions for the product to meet or exceed the performance requirements listed in the "MINIMUM PERFORMANCE REQUIREMENTS" section. 6. Open gear lubricants supplied under this specification must be specifically formulated to protect surfaces, reduce wear, and provide satisfactory service life under all anticipated operating conditions. 7. Open gear lubricants supplied under this specification must have excellent water tolerance and rust preventive qualities, as well as minimal dripping qualities for operation over wide temperature ranges. 8. Should the material furnished under this specification contain a diluent to improve dispensability, special care must be exercised to ensure its compatibility with all centralized lubrication system components, i.e., gaskets, o-rings, vent valves, etc., and oil seal lip materials (Nitriles, Viton). Reference ASTM D 4289-03. 9. For extended use in low temperature areas, open gear lubricants supplied under this specification should be capable of slumping in containers and should be pumpable through lube lines without the aid of heat tracing. In order to minimize compatibility problems, it is desirable that the thickener and additive system be compatible with the additional grades that are suitable for the other ambient temperatures.

ISSUE: The specification for open gear lube (OGL) prescribes a viscosity based on ambient temperature at the point of application. Particularly in cold climates, some customers have selected seasonal lubricants with minimal viscosity allowing it to be pumped to external components. However, under certain conditions these lubricants may not meet the viscosity requirements of the hoist pinions and bull gear (located in the heated machinery room) and could provide marginal lubrication which could lead to premature distress on the gear teeth. 1 OF 3

ISO 9001: 2000 Registered Firm

ACTION: To meet the specification, a solvent cut-back (non-chlorinated diluent type) lubricant or a pumpable high viscosity grease or compound may be required for cold weather applications. If the owner/operator chooses, a split lube system may be adapted that will allow the specified open gear lubricant to be utilized year round for the hoist pinions and hoist drum gear, and a seasonal low viscosity open gear lubricant for external components. To obtain a quotation for split lube system components please contact our Aftermarket Service Parts Group. The high viscosity of the OGL may provide difficulty pumping in cold weather applications. The factory supplied systems have heat sources designed for pumpability during cold start ups. It is recommended to effectively plan refill intervals to avoid transport and refills during the coldest times of the year.

OPEN GEAR LUBRICANT The new specification clarifies the viscosity requirement of the lubricant for the hoist pinions and hoist drum gear. Lubricant viscosities for systems other than the hoist will remain as before. The OGL viscosity requirements for the electric mining shovel equipment are as follows:

SCOPE: 1. This specification covers “Open Gear Lubricant”. 2. Materials furnished under this specification are primarily intended to lubricate open gears, but may also be used to lubricate racks, bushings, rails, rollers, dipper handles and propel mechanism components. 3. The material furnished under this specification must be dispensable through the distribution lines of a centralized lubrication system to the most remote application point, at the lowest anticipated operating temperature. It must not plate or plug components of the centralized lubrication system such as injectors, metering blocks, or spray nozzles. 4. This specification covers open gear lubricants that may be applied in service at temperatures ranging from -50°C (-58°F) to the highest ambient temperatu re conditions. The particular grade or consistency selected must perform within the specific temperature range in which it is utilized. The temperature may vary significantly between external components in cold climates and components located within heated enclosures and must be considered during lubricant selection.

PHYSICAL CHARACTERISTICS: 1. Materials furnished under this specification are produced with highly fortified blends of viscous fluids combined with additives to form stable, long lasting, high load carrying, wear resistant films that lubricate under mixed film and boundary conditions. Lubricants addressed under this specification may be defined by AGMA 6014-A06 Annex D as (1) Residual [asphaltic (bitumen)] compounds, (2) High viscosity oils, (3) Compounds or (4) Greases. 2. Open gear lubricants supplied under this specification must have excellent adhesive and cohesive qualities, must not chip or throw off, and must provide sufficient film thickness and scuffing resistance to prevent metal to metal contact between applications of the lubricant under all operating conditions. Therefore: (2) High viscosity oils are NOT recommended due to performance characteristics at relatively slow speeds and frequent stop/start application; and (4) Greases inherently provide marginal film thicknesses at low speed which requires properly designed additive packages and thickener selection, stringent break in procedures and more frequent lubricant intervals. 3. Various grades or consistencies of open gear lubricants may be required to provide proper lubrication and application properties over a wide range of ambient temperatures. The consistency of the lubricant as applied must be appropriate for the method of application, and the in-service consistency shall be appropriate for the lubricant to meet or exceed the minimum performance requirements listed in the “MINIMUM PERFORMANCE REQUIREMENTS” section.
