Title:
METHOD OF ACQUIRING CONTACT ANGLE OF ANGULAR CONTACT BALL BEARING AND METHOD OF MANUFACTURING BEARING DEVICE FOR WHEELS
Document Type and Number:
WIPO Patent Application WO/2020/196089
Kind Code:
A1
Abstract:
This method of acquiring a contact angle of an angular contact ball bearing comprises: a first detection step for detecting the rotational speed of one raceway ring 12 of an angular contact ball bearing 10; a second detection step for detecting, from the outside, the deformation of the other raceway ring 11 according to the revolution of a ball 13 of the angular contact ball bearing 10; and a calculation step for obtaining a contact angle α of the ball 13 by using the detection result of the first detection step, the detection result of the second detection step, and specification data of the ball 13.
