Flexible Bearings

Flexible bearings use the controllable elastic deformation of flexible elements to transmit motion and power. Its characteristics are large and applicable transmission, high precision, small empty return, large load capacity, small size, light weight, stable transmission, low noise, Can transmit movement to the sealed space. The harmonic drive transmission includes three basic components: wave generator, flexible wheel, rigid wheel and flexible bearing. The flexible bearing is the core component, and the transmission achieves the performance requirement of high reduction ratio through the elastic deformation of the bearing.

During the operation of the flexible bearing, the inner ring is installed on the elliptical cam, which bears the cyclic stress load during work, and the outer ring is installed on the flexspline. The elastic color occurs with the rotation of the cam during operation, which not only bears the cyclic stress load, but also bears Alternating stress load.

Flexible bearings are mainly subjected to alternating stress. Due to their relatively thin wall thickness, certain deformation occurs when matched with the cam. The inner and outer rings and rolling elements are all made of high-carbon chromium bearing steel, and the retainer is a nylon integral retainer.
