  • Method of determining the contact angle of a ball bearing
    Patent number: 8467045
    Abstract: To determine the contact angle of a ball bearing, one of two rings is rotated while the other ring is held stationary. The number of revolutions of the rotated ring and the number of revolutions accomplished in the same period by the balls, and therefore by the retaining cage, are detected. The revolutions of the balls are detected through an optical detecting device which projects a radiation through the bearing, in the gap between the outer and inner rings, whereby the radiation is intercepted directly by the balls and/or the cage. The contact angle is determined using the following parameters: the number of revolutions of the rotating ring, the number of revolutions of the balls or of the cage, the diameter of the balls, and the pitch diameter.
