The Method of Grinding Tapered Roller by Self-positioning Device with Buffer on Spherical Surface Grinding Machine

Abstract

The invention discloses a method for a buffering self-positioning tapered roller on a ball-based surface grinding machine. According to the method, a buffering self-positioning device is used, the buffering self-positioning device can realize automatic positioning of the tapered roller and can also realize revolution of the tapered roller, a buffer shaft sleeve and an inner hole of a toothed shaftare provided with a radial gap, the radial gap completely meets a requirement that the buffer shaft sleeve generates micro deformation, the stability of rear thrust generated in the process of grinding the tapered roller by the ball-based surface grinding machine is ensured, errors of large curvature dispersion difference of a tapered roller ball-base surface and large end surface circle run-outfluctuation are reduced due to the stability of the rear thrust, so that the grinding precision and the grinding efficiency of the tapered roller are improved.

Description

technical field [0001] The invention belongs to the technical field of bearing grinding, in particular to a method for grinding tapered rollers by a spherical surface grinder through a self-positioning device with a buffer. Background technique [0002] At present, domestic grinding machines for grinding the ball base of tapered rollers usually use non-magnetic penetrating forming grinding wheels for grinding. The formed inner cone angle clamps the rolling surface of the tapered roller. Since the left and right guide wheels rotate in opposite directions and the speeds are not equal, the rotation speed of the left guide wheel is lower than that of the right guide wheel, and the tapered roller pushes the isolation plate to make it circle The center of rotation of the guide wheel rotates in and out of the grinding area, and then grinds through the concave spherical shaped grinding wheel. [0003] Due to the adjustment error of the base surface of the tapered roller, the above-...
