Types of Double Reduction Final Drive

A typical double reduction axle 

 

• The first reduction is obtained between the bevel pinion and crown wheel

• A lay shaft carries both bevel crown and spur pinion the lay shaft is carried on bearings in 

  the casing

 

Spur pinion meshes with spur wheel to which differential case is fitted by means of bolts

The second reduction is obtained between Spur pinion and spur wheel

 

Double Reduction Final Drive:

The second type of Double reduction final drive:

   

• In this type first reduction is obtained between the bevel pinion and crown wheel

 

• Differential case is fitted to the crown wheel

 

  The lay shaft connected to the sun wheel carries spur pinions 

 

  The spur pinion meshes with the spur wheel fixed to the axle shaft 

 

  The second reduction obtained between the spur pinion and the wheel after the differential
