final drive for excavator change the direction of the power transmitted. for hitachi ,komatsu ,caterpillar etc

A final drive is that part of a power transmission system between the drive shaft and the differential. Its function  is  to  change  the  direction  of  the  power transmitted  by  the  drive  shaft  through  90  degrees  to  the driving  axles.  At the same  time.  it provides  a  fixed reduction between the speed of the drive shaft and the axle driving the wheels. The  reduction  or  gear  ratio  of  the  final  drive  is determined by dividing the number of teeth on the ring gear  by  the  number  of  teeth  on  the  pinion  gear.  In passenger vehicles, this  speed  reduction  varies  from about 3:1 to 5:1. In trucks it varies from about 5:1 to 11:1. To calculate rear axle ratio, count the number of teeth on each gear. Then divide the number of pinion teeth into the number of ring gear teeth.
