Abstract: The wear-compensation device for a gear comprises a fixed support capable of being fixed axially on an external element in order to keep the device on the said external element, a bearing designed to be mounted on a shaft comprising one of the wheels of the gear, an eccentric mounted on the bearing and designed to be in contact with the external element, the said eccentric being able to move angularly relative to the fixed support. The device also comprises a torsion spring mounted axially between the fixed support and the eccentric and capable of exerting a circumferential preload force on the said eccentric, the said spring comprising a first end mounted inside a recess of the eccentric and a second end interacting with the fixed support.

Abstract: A bearing assembly is for a mechanism including a housing and a rotatable shaft disposed within the housing. The bearing assembly includes a sleeve disposable within the housing and having an inner circumferential surface defining a bore and a radial surface extending radially inwardly from the inner surface. A bearing is disposed within the bore and includes inner and outer races and rolling elements disposed between the races, the inner race being coupleable with the shaft such that the shaft and the inner race rotate as a single unit. Further, a biasing member biases the outer race generally against the sleeve radial surface or a housing radial surface to prevent axial displacement of the outer race during shaft rotation. Preferably, a retainer couples the biasing member with the outer race to retain the bearing and the biasing member within the bore when the assembly is separate from the housing.

Abstract: The invention relates to a monitored roller bearing device, comprising a non-rotating race (10), a rotating race (12), at least one row of rolling elements (14) arranged between two rolling tracks (11, 13) on the rotating race (12) and non-rotating race (10) and an information detection module, which comprises a non-rotating sensor unit (29) and a rotating (12) encoder (28). Said device comprises a means for fixing the sensor unit (29) relative to a support (3), by generating an axial force between a support surface (34b) on the sensor unit (29) and a support surface (7) on the support (3), while permitting an axial displacement of the sensor unit (29) relative to the support (3).

Abstract: An anti-friction bearing device comprising an outer ring (11) provided with an outer surface and a bore on which a toroidal bearing inner race (14) is formed, an inner ring(15) which is provided with a bore and a cylindrical outer surface on which a toroidal bearing outer race (18) is formed, a row of balls (19) which are disposed between the two bearing races, and a cage which can maintain a regular circumferential spacing between the balls. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the outer surface of the outer ring and the diameter of the balls ranges from 0.4 to 0.7. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the radial thickness of the inner ring when taken between the bottom of the outer bearing race and the bore of the inner ring ranges from 1.1 to 1.6.

Abstract: The present invention provides an instrumented rolling bearing device having an outer ring, an inner ring, at least one row of rolling bodies arranged between two raceways of the outer and inner rings, and an assembly for detecting rotation parameters, this assembly having a non-rotating sensor unit and a rotating encoder member. The device allows for angularly immobilizing a non-rotating part of the device on a support while at the same time allowing relative axial movement of the device with respect to the support.
