Flexible bearings utilize the controllable elastic deformation of flexible components to transmit motion and power. They are characterized by large transmission ratios, wide applicability, high accuracy, small backlash, large load-bearing capacity, high efficiency, small volume, light weight, stable transmission, low noise, and the ability to transmit motion to sealed spaces. In the operation of flexible bearings, the inner ring is installed on an elliptical cam, which bears cyclic stress loads. The outer ring is installed on a flexible wheel, and elastic deformation occurs with the rotation of the cam. It not only bears cyclic stress loads, but also alternating stress loads.
