Abstract
The invention provides a manufacturing method for thin-wall bearing and a method for machining a thin-wall inner ring/outer ring as well as a precision flexible bearing. The method for machining the thin-wall inner ring/outer ring comprises the following steps of: S0, providing a thin-wall ring with machining allowance left; S1: reinforcing along the radial direction and/or axial direction of the thin-wall ring; S2: carrying out quenching-tempering heat treatment on the reinforcing ring obtained by reinforcement in the S1; S3: carrying out corresponding grinding, hard cutting and super finishing on the reinforcing ring after receiving heat treatment, which includes removal of the machining allowance and a reinforcing part obtained by reinforcement in the S1, thereby obtaining finished thin-wall ring product. The thin-wall ring reinforced machining method substantially reduces and even avoids deformation of the thin-wall ring in all manufacturing links, thereby obtaining very high machining precision. The precision thin-wall bearing and the precision flexible bearing can be manufactured by fitting of the precision thin-wall ring and a precision rolling body.
