An adjustable spacer with a non-hardened intermediate portion therebetween is mountable between a pair of roller bearings also mounted on a shaft such an axle or spindle or the like. The intermediate portion allows the spacer to collapse in the axial direction to maintain desired axial loads on the bearings.

A bearing assembly unit (5) includes an outer holder (10) configured with a cylindrical member; an inner holder (20) that is configured with a cylindrical member, and inserted into an inner circumferential surface of the outer holder (10) so as to be movable in an axial direction; and a rolling bearing element (30) which is inserted into an inner circumferential section of the inner holder (20) so as to be fixed at least in a circumferential direction, and into which a shaft (40) is inserted so as to be fixed there; wherein, between the outer holder (10) and the inner holder (20), there is provided a rotation restriction mechanism (12, 22) that prevents a relative rotation between the outer holder (10) and the inner holder (20).

The invention relates to a securing element (1; 1a) for a bearing device (50) in a housing (20) of a drive device (10), wherein the plate-like securing element (1; 1a) has two side legs (34, 35) and a base leg (36) which connects the side legs (34, 35), wherein, between the base leg (36) and the side legs (34, 35), there is formed a cutout (38) for receiving a shaft (12) which is mounted rotatably in a bearing (15), wherein the two side legs (34, 35) are designed to interact, by means of a first face side (21), with the bearing (15) and, by means of a second face side (23), with a stop surface (33) in the housing (20).

The ball joint device (10) for suspending a turbine engine from a strut or suspending equipment on the body of a turbine engine. Said device comprises a first member (12), one end of which carries a ball joint (14) and is interposed between the two lugs (16, 17) of a second member (18), the ball joint comprising a bore (28) for the passage of a shaft (30), the ends of which shaft pass through openings (20, 22) in the lugs. A first (16) of the lugs comprises or carries first means for axially holding the shaft on the side opposite the ball joint, which means comprise a cover (52, 52), and a second (17) of the lugs comprises or carries second means (38) for axially holding the shaft on the side opposite the ball joint. The device further comprises a resilient member (62, 62) that is deformable under compression and is held by the cover, said resilient member (62, 62) being designed to bias a support element (40), through which the shaft passes and which is in axial abutment on the ball joint (14), axially in a direction away from the cover.

A bearing assembly (1) for preload measurement, having at least one rotary element (2, 3), wherein the at least one rotary element (2, 3) includes a radial (4) and/or axial receptacle (5) for a rolling bearing (6), wherein the at least one rotary element (2, 3) includes at least one measurement device (7, 8) in the region of the receptacle (4, 5) for measuring the rolling bearing preload, and wherein the at least one measurement device (7, 8) is located inside the at least one rotary element (2, 3).

A system for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft and a press mechanism in fluid communication with a source of fluid and configured to provide a compressive load to the bearing. The press mechanism includes a switch having a base and a piston in communication with the fluid such that an increase in a pressure of the fluid results in the piston extending upwardly from the base and a decrease in the pressure of the fluid results in the piston retracting toward the base. The switch includes a lower proximity sensor and a higher proximity sensor. The piston is configured to extend upwardly from the base past the lower proximity sensor and to trip the higher proximity sensor. The switch is configured to control the increase in the pressure in response to the piston tripping the higher proximity sensor.

A method for preloading a bearing includes releasably, threadably, and directly attaching an attaching member to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle. A frame is axially separated from, and coupled to, the attaching member. A plurality of extensions extends from the frame axially past the attaching member toward the wheel hub assembly. An adjustment mechanism moves the frame and the plurality of extensions axially towards the wheel hub assembly to contact the wheel hub assembly and/or the bearing to apply a preload to the bearing within the wheel hub assembly.

A preload assembly for bearings comprising in combinations a threaded bolt, an anti-rotational washer, a serrated edge locking washer, and a threaded locking nut having a shallow outer profile and at least four locking notches in an outer edge thereof.

An apparatus for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft. A press mechanism is coupled to the attaching member and is configured to provide a compressive load to the bearing. An optical sending unit is configured to output a high intensity light to allow a user to locate a shaft slot of the shaft to align the press mechanism relative to the shaft when the attaching member connects to the shaft.

A mechanical link comprises a shaft having a central axis, a first end portion threaded in a first direction, and a second end portion threaded in an opposite second direction. A first mounting interface and second mounting interface are respectively coupled with the first end portion and second end portion. A tubular sleeve circumscribes a portion of the shaft and comprises a slot. A pin extends from the shaft and passes through the slot. A stop is coupled with the second end portion and fixed to the shaft. A washer circumscribes a portion of the shaft between the tubular sleeve and the stop. A spring biases the tubular sleeve toward the stop. A first jam nut is coupled with the first end portion between the first mounting interface and the spring. A second jam nut is coupled with the second end portion between the second mounting interface and the stop.
