First Claim
Patent Images
1. A power train component comprising:
- an input shaft;
driving gear fixed to said input shaft;
a driven gear meshing with said driving gear;
at least one bearing assembly for supporting said input shaft;
a housing for mounting said bearing assembly; and
,a sensor for detecting deflection of one of said driving and driven gears reacting to the level of torque transmitted between said driving and driven gears.

Abstract
A work machine having a diesel engine driving a plurality of ground movement devices to tow an agricultural implement. A torque estimating system is employed to determine the level of torque in the drive train between the diesel engine and the ground movement devices. The torque estimation device is a sensor determining the axial and radial deflection of an input shaft as a function of the torque transmitted between a pair of adjacent gears in the power train.
