LOCO INTRODUCTION- E2 BRIEF DESCRIPTION OF THE LOCO: The WAG-9 &9H is a high-speed main line locomotive for hauling FREIGHT trains and WA-! is a high-speed main line locomotive for hauling A""E#GER trains$ This locomotive is a dou%le-ended design 'hich means that there are a driver(s ca% and coupling elements at %oth ends of the loco $
Mechanical Features: The three a)les three motor *o-*o %ogie assem%lies assem%lies is one of the ma+or parts of the locomotive$ T'o %ogie assem%lies support the entire 'eight of the locomotive and provide a means for transmission of the tractive effort to the rails$ The %ogies are designed to 'ithstand the stresses and vi%rations resulting from normal rolling stoc, applications$ An An important function of the %ogie is to a%sor% and isolate shoc, caused % variations in the trac,%ed$ t rac,%ed$ The suspension sstems minimi.e the transmission of these shoc,s to the locomotive under frame$ The traction motors are suspended in the %ogie frame and on the individual a)is$ The motors transmit their energ to the driving a)les through a gear%o) mounted on the driving a)le$ The force from the driving a)les is transmitted to the contact point %et'een the 'heel tread and the rail$ Traction force is in turn transmitted through the a)le +ournal %o)es and guide rods to the %ogie frame$ The push-pull lin, rod connected %et'een the %ogie transom and car under frame transmits the tractive forces to the car %od$ %od$ The WAG-9/9H is e0uipped 'ith the follo'ing pneumatic %ra,ing sstems1 automatic train %ra,e direct loco %ra,e par,ing %ra,e and anti-spin %ra,e$ As As 'ith the tractive effort %ra,ing effort is transmitted to the %ogie frame % the a)le +ournal %o)es and guide rods and from the %ogie frame to the locomotive % the traction rods$ Isolation and a%sorption of shoc, loads and vi%ration is performed % the primar and secondar suspensio suspension$ n$ 2ovement %et'een the car %od and %ogie is smoothl controlled % the primar and secon

FOTOR SECTION - E2 TRACION MOTORS Traction Motors used in our loco are of DC series Motors. There are six Traction Motors, one per each axle is provided.

These Traction Traction Motors are axle hun" nose suspended tpe and are provided with "rease lu!ricated roller !earin" for ar#ature shaft as well as for suspension !earin" for 'ITAC'I #otors. TAO $%& #otors are provided with "rease lu!ricant roller !earin"s for the ar#ature shaft and 8ournal !earin"s for suspension. The are oil lu!ricated ! wic9s -felt pads/, with the wic9 holders which are supplied with oil ! an axle driven pu#p. There are two oil wic9s containers, which are in co##unication with each other throu"h a co##on passa"e. An surplus oil of the container will return to the oil su#p. Two oil dip stic9s are provided, one on the wic9 container and the other on the #ain oil su#p in which the oil pu#p is fitted. The oil should !e chec9ed on the upper su#p -wic9 container with a dip stic9/. The dip stic9 will w ill have #ini#u# and #axi#u# #ar9in"s. 2hile chec9in", it should !e ensured that the oil level is !etween #ini#u# and #axi#u# #ar9s. The oil level should !e chec9ed i##ediatel after service runnin". Oil level !elow the #in level -!otto# #ar9/ on the dip stic9 indicates lac9 of oil deliver. New oil is to !e added throu"h the dip stic9 tu!e on the wic9 container. container. The total oil capacit of the lu!rication su#p is +.+ liters at #ax of oil level. The difference !etween #axi#u# and #ini#u# #ar9s on the su#p dip stic9 represents a :uantit a!out %.+lits of oil. The Traction Traction Motor drives the axle throu"h a ri"id strai"ht tooth "ear. "ear. One end of the ar#ature shaft is shrun9 fitted pinion, which is #eshed with drive "ear fitted to the axle. There fore, the tooth wheel is re:uired lu!rication. These "ears are housed in a "ear case and provide lu!rication. Top "ears cardiu# co#pound are poured in to the "ear case and the capacit of "ear case is $ liters at #axi#u# oil level. A dip stic9 is provided p rovided to #easure the oil level with two #ar9in"s #axi#u# and #ini#u#. The oil should !e !etween #ini#u# and #axi#u# #ar9s. The distance !etween #ini#u# and #axi#u# are corresponds to approxi#atel 3 liters of oil. The current readin" of oil level will !e availa!le if chec9ed at least * #inute after the loco has co#e to a stop. ;resh oil is introduced throu"h the dipstic9 tu!e. The "ear case is fitted to the Traction Traction Motor !od with !olts and nuts !oth hori
