First Claim
Patent Images
1. A power train component comprising:
- an input shaft;
a 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, wherein said sensor is positioned at an angle with respect to a plane perpendicular to the rotational axis of said input shaft so as to provide access around said bearing assembly.

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.
