Abstract: A bearing actuator module comprises a support bearing assembly having a mounting ring (1) adapted to be mounted to an application support structure; a rotatable gear (G2) received within the mounting ring for rotation relative to said mounting ring. A drive subassembly (DS) which rotates said rotatable gear (G2) is removably received in the support bearing assembly. The drive subassembly comprises a stationary gear (G1), a plurality of pinion assemblies, each of which comprises a first pinion P1 which meshes with the gear G1 and a second pinion which meshes with the gear G2. The pinion assemblies are mounted in a carrier (10), which is rotated by a motor (M). A brake assembly (B) is provided to prevent rotation of the rotatable gear (G2) when the motor is not activated. Additionally, a feed back or position sensor is provided which indicates the relative rotational position of the carrier (and hence of the rotatable gear (G2)).

Abstract: A bearing assembly (A-H) enables one member (4) to rotate relative to another member (2) about an axis (X). It includes a bearing (6) having an inner race (54) on one of the members, an outer race (74, 126, 164, 250) in the other member, and rolling elements (58) between raceways on the two races. A seal (10, 180, 210, 256) excludes contaminants from the interior of the bearing, and it includes a wear ring (92, 184, 214, 276) carried by an extension (80, 128, 144, 168, 252) on the outer race beyond the raceway of that race, a contacting wear ring (90, 182, 212, 278) carried by the member on which the inner race is located or else by a can (110, 230, 254) that is fitted to the inner race. The seal also includes backing elements (94, 96, 192, 194, 216, 218, 294) for supporting the wear rings on that which carries them, and in most instances the backing elements exert a biasing force on the wear rings to maintain them in contact, so that they establish a dynamic fluid barrier. The backing elements may include O-rings (94,96), polymer connecting segments (200) or springs (292) and a membrane (294).

Abstract: A bearing system (A) that supports a shaft (4) in a housing (2) includes two single row tapered roller bearings (6, 8) mounted in opposition. One of the bearings (8) compensates for thermal variations that would otherwise produce excessive preload in the system. It has a conventional cup (48) in the housing and tapered rollers (52) arranged in a single row along the raceway (54) of the cup. It also has a compensating assembly (50, 100, 110, 120, 130) on the shaft, and it includes a ribless cone (60) having a raceway (70) around which the rollers are organized, an axially displaceable rib ring (64) for positioning the rollers, a spring (66) for urging the rib ring against a stop surface (74) on the cone, and a compensating ring (68) formed from a material having a high coefficient of thermal expansion for displacing the rib ring against the force exerted by the spring when the temperature of the compensating assembly exceeds a prescribed set point temperature so as to reduce preload in the bearing system.
