An apparatus for use in connecting a cover member to a retaining member coupled to a nut mounted to a shaft includes a body portion, arms, and a plurality of pressing members. The arms extend from the body portion relative to the nut such that contacting portions of the arms contact a rear side of the nut to connect the body portion to the nut. The plurality of pressing members extend from the body portion and is alignable with the plurality of tabs of a cover member when the cover member is located between the body and the nut. The body portion includes a press mechanism configured to cause a first pressing member of the pressing members to contact a first tab of the cover member to deform the first tab toward a retaining member coupled to the nut mounted on the shaft.

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.

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 bearing assembly comprises a cone member configured to receive rollers therein. A bearing cup is configured for receipt of the cone member therein and for rolling contact with the rollers thereon. A bearing cup pocket extends circumferentially about the rear face of the bearing cup and that is configured to receive a biasing member therein.

A double-row angular contact ball bearing for a CT scanning device includes an inner member including a pair of raceway rings. The raceway rings have positioning holes into which a positioning member is inserted, to thereby suppress radial decentering of the raceway rings. Both the raceway rings are fastened by fixing bolts. The raceway rings have opposed end surfaces, and are fastened by the fixing bolts to bring the end surfaces into abutment against each other to apply a preload at a fixed position between balls and raceway surfaces. The following relationship is set: Db/h≦0.26, where Db represents a diameter of each of the balls, and h represents a radial dimension from a center of each of the balls to an inner diameter of the inner member.

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 adjustment drive for a steering column may include a drive unit having a threaded spindle that is supported in a gearbox housing at a bearing portion so as to be rotatable, with the threaded spindle including a threaded portion with a spindle thread that is axially adjoined to a shaft portion on which a gear wheel is arranged in a rotationally secure manner. The gear wheel meshes with a drive wheel that is coupled to a motor. Between the threaded portion and the gear wheel a peripheral bearing groove with a groove base may extend between groove flanks thereof. The bearing portion may be disposed in the bearing groove in a region of the groove base, and the bearing portion may be supported in a sliding manner in a bearing opening of a bearing plate that engages radially in the bearing groove.

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 multi-part adjusting element is proposed, which makes possible a very precise adjustment of a shaft bearing.

A tensioning arrangement for a bearing ring, which introduces a compressive force towards a rotational centre of the bearing ring, to prevent the bearing ring distorting as a shaft supported by the bearing turns. The tensioner arrangement includes a strap and a tensioner. The strap has a connector at each end, and tensioner has an element for connecting to the connectors. The tensioner also has an element for applying tension to the strap. In use, the strap is arranged around the bearing ring and a circumferential length of the strap in contact with the bearing ring is reduced, thereby applying compressive force to the bearing ring.
