Torque arm design

Whether a standard torque arm is used or whether you design and make a torque arm, check the strength of each element in the following manner.

1. Check the torque arm and fixing bolt

Check according to the torque arm reaction force R.

R = T + W × G C

2. Selection of bearing

Check according to the 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

*For the direction of rotation shown in the figure to the left, the output torque is positive. When it is reversed, the output torque is negative.

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