Abstract

The invention discloses a grinding technology for joint bearing inner rings and relates to the field of machinery. The grinding technology comprises processes of designing, machining a technical cylindrical belt, distributing the machined technical cylindrical belt to the two sides of an oil gallery, clamping a joint bearing on a grinder, rough-grinding the joint bearing, fine-grinding the joint bearing and final-polishing the joint bearing. According to the grinding technology for the joint bearing inner rings, the problems that existing joint bearing inner rings are not liable to be molded, not stable in size controlling and bad in appearance quality are solved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a grinding process for the inner ring of a joint bearing. Background technique [0002] The joint bearing is mainly composed of an inner ring and an outer ring, which can perform swinging, tilting and rotating motions under low speed and heavy load conditions. Taking the radial spherical plain bearing as an example, because the raceway of the inner ring is a convex spherical surface, there is no reliable positioning reference when grinding the raceway and inner diameter, so it is very easy to have ellipse, round edge, taper, large difference in wall thickness, etc. Quality problems, dimensional accuracy is also difficult to meet the design requirements. [0003] The existing and processing technology is the original grinding process of the inner ring of the joint bearing: grinding end face - rough grinding raceway - rough grinding inner diameter - fine grinding racewa...
