Torque arm design

When using a standard torque arm or designing and manufacturing your own torque arm, please check the strength of each element as follows:

1. Check the torque arm and fixing bolts

Check using torque arm reaction force R.

R = T + W × G C

2. Bearing selection

Check bearing reaction forces A and B.

A (bearing a) = L1 × (R - W) -D × R L2

B(bearing b) = (L1 + L2) × (R - W) - D × R L2

*The output torque is + when rotating in the direction shown on the left, and - when rotating in the opposite direction.

  • T: Output torque N・m{kgf・m}
  • W: Weight of reducer kg{kgf}
  • R: Torque arm reaction force kg {kgf}
  • G: Distance between the center of the driven shaft and the center of gravity of the reducer m
  • C: Distance between the driven shaft center and the anti-rotation stopper m
  • D: Distance between the center of the reducer and the anti-rotation stopper m
  • L1: Distance m between the center of the reducer and bearing b
  • L2: Distance between bearing a and bearing b m
