What is Ratcheting torque?
When excess impact torque is applied during operation, the engagement of the teeth between the circular spline and the flexspline may be put momentarily out of alignment instead of damaging the flexspline. This phenomenon is called “ratcheting”, and the torque is called “ratcheting torque”. Operating the drive without fixing ratcheting will result in earlier abrasion of the teeth and shorter life of the wave generator bearing due to the effect of the grinding powder generated by ratcheting.
