Elastomeric Couplings Now there’s a new solution to one of the most persistent and troublesome problems facing maintenance personnel – periodic coupling failure and the downtime and expense that goes with it. If a new insert is needed, a low-cost replacement can be installed in minutes without moving either the prime mover or the driven equipment. There are only four parts to PowerStream ® couplings: The two identical hubs (Numbers 1 and 2) are made of high-strength cast iron, cast steel or alloy aluminum, each with four, six or eight teeth, depending on load and size. The split insert (Number 3), which is made of specially compounded polyurethane, fits between the hubs. The outer holding rings (N umber 4) are made of steel, polyamide or bronze. The coupling requires no nuts or bolts.
ASSEMBLY AND DISASSEMBLY
POWERSTREAM FEATURESAND BENEFITS
A fter hubs (1) and (2) and holding ring (4) are installed on shafts, the teeth are then aligned parallel to each other, but not touching. O nce installed, the hubs never need to be moved again. The elastic insert (3) can then be installed in the slots formed by the parallel teeth.
• C hangeout of coupling insert is faster than any other coupling.
3
• C ustom compounded polyurethane inserts can be provided in a variety of durometers. This allows for both high damping and high torque use.
2
• Polyurethane insert is very resistant to corrosion, chemicals and oils. Standard Insert – 40° to 180° F.
1
When the insert is in position, slide retaining ring (4) onto the polyurethane insert. C entrifugal force will expand the elastic insert to fit tightly to the inside of the retaining ring.
• High Temp inserts – up to 300° F. • No lubrication or maintenance. • C an rotate hubs independently for motor test. • No metal to metal contact.
To disassemble, remove the ring. The insert can then be quickly and easily removed and replaced. No special tools, screws, bolts or other fasteners are needed.
• Large bore and torque capacity. • Horizontal and vertical operations using standard inserts and retaining rings.

NOTES: (1) High Damping Inserts (HD) will be supplied as standard unless specified. High Torque (HT) Inserts can be supplied for standard temperatures as well as for high temperature applications. (2) Maximum speeds are based on Cast Iron Hubs. Higher speeds may be attained using Ductile iron or Steel Hubs - Consult J ohn Crane Engineering (3) Maximum bores for ductile iron hubs - use those shown for steel. (4) Distance Between Shaft ends (DBSE) is based on the shafts mating flush with the end of the hub face. Short or Longer shaft separations may be obtained by overhanging the hub or extending the shaft. (5) Weights and Inertia’s are based on solid hubs

Standard shaft separation applies when the shafts are mounted flush to the end of the hubs. In order to reach the minimum and maximum shaft separations allow the shaft end to extend beyond or sit within the hubs equally.
POWERSTREAM DROPOUT COUPLING FEATURES AND BENEFITS • High torque capacity
• Higher maximum speeds
• Lighter weight
• Non-lubricated
• No metal to metal contact
• Larger bore capacity
• Longer shelf life
• Easy installation
A long with the benefits listed above, the Powerstream Drop O ut C oupling is also interchangeable with many competitive drop out couplings including the Falk T31 ™ and the K op-Flex Elastom eric™ .

COUPLING SELECTION METHOD
EXAMPLE
Data required for C oupling Selection:
• Driven equipment: Force draft fan • Electric motor: 75 HP. R.P.M. of the driver: 1750 • Motor bore: 2.38" • Fan bore: 2.00" (1) Service Factor of a force draft fan (SF1) =1.5 Service Factor of an electric motor (SF2) =1.0 (2) Maximum HP/100 per rpm = (HP * 100) / rpm * SF1 * SF2:
• A pplication details (for Service Factors)
• Horsepower of the driver.
• R.P.M . of the driver.
• Shaft details of the driving and driven equipment.
(1)D etermine the service factors (SF1 + SF2) f rom the application and classification listsnoted on page 6.
(75HP * 100) / 1750 * 1.5 * 1.0 =6.43
(2)Calculate the maximum HP/100 rpm rating:
Coupling selection based on maximum ratings: (A3 has a maximum rating of 8.0 HP/100 rpm) (3) Compare bore requirements to the max. bore capacity of the A3: the max. bore of an A3 is 2.75" Maximum speed of the A3 is 4200 unbalanced. ∴
M ax. HP/100 rpm = ( HP * 100) / rpm * SF1 * SF2 Select the coupling which has a higher rated. M ax HP/100 rpm as shown on each table. (3)C ompare the maximum rpm capacity and bore requirements to the catalogued limi ts for the coupling selected.
