Title:
GRINDING DISK KIT, APPARATUS AND METHOD FOR FINISHING ROLLING SURFACES OF BEARING ROLLER
Document Type and Number:
WIPO Patent Application WO/2020/024878
Kind Code:
A1
Abstract:
A grinding disk kit for finishing rolling surfaces of a bearing roller, comprising a pair of first and second grinding disks (21/22) that are coaxial, a front face (211) of the first grinding disk comprising a set of radially distributed linear grooves, and a front face (221) of the second grinding disk comprising one or more helical flutes. During grinding, one bearing roller to be processed is distributed at each of intersections of the corresponding helical flutes (2211) and the linear grooves (2111), and the rolling surfaces thereof respectively are in contact with working faces (21111/22111) of the linear grooves and the helical flutes. The bearing roller to be processed translates along the linear grooves while rotating about their own axes under the friction driving and thrusting actions of the working faces (22111) of the helical flutes. The grinding disk kit can improve the shape precision and dimensional uniformity of rolling surfaces of a bearing roller, improve the processing efficiency, and reduce the processing cost. Also provided are a grinding apparatus and a grinding method.
