Adjustably prestressed rolling bearing

Image Number 2 for United States Patent #4913564.

The rolling bearing comprises a housing (10), rolling elements (20), at least one ring (30) in two ring parts (31, 32) freely mounted one inside the other and defining raceways (231, 232) on which roll the rolling elements, and an elastically yieldable prestressing device (50). This device is adjustable between two states, namely a first state in which an elastically yieldable member (53) exerts relatively no prestress for permitting the assembly and a second state in which the elastically yieldable member (3) exerts the prestress for normal operation of the bearing. Application in the case where the other ring (40) is a shaft carrying another raceway (240) along which the rolling elements roll.
