Abstract: A bearing assembly for a rotating shaft includes a plurality of frangible bolts located concentrically of an axis of rotation for attaching a bearing housing radial flange portion to a support structure, each having a frangible portion located between axially spaced-apart radial flanges whereby the bearing housing flange portion is spaced-apart axially from the support structure.

Abstract: A locking ring assembly retains a bearing to a shaft rotatably supported on a first axis of rotation. Guide pins extend axially from an annularly shaped bearing retainer slidably disposed on the shaft toward the pressure ring, also slidably on the shaft. A head of the guide pins is slidably disposed and captured in adjusting apertures of the pressure ring. Pressure screws in the adjusting apertures of the pressure ring translate axially in the apertures of the pressure ring when rotated, engaging the guide pin heads to displace the pressure ring from the bearing retainer. The pressure ring reacts against a reaction element disposed on the shaft opposite the bearing retainer to develop an axial thrust load against the bearing.

Abstract: A wheel hub assembly for a non-driven axle including a hub, a bearing retainer ring and a bearing. The bearing retainer ring is secured to the hub by engagement of the wheel mounting studs with the hub. A portion of the bearing retainer ring directly engages and positively provides an axial retention load on the bearing. The resulting structure is a compact and light weight wheel hub assembly having simplified, cost efficient construction.

Abstract: A method and apparatus for mounting a rotating part between two bearings designed to transmit radial and axial forces without axial and radial play. Each bearing includes a rolling element positioned between an outer part and an inner race surrounding the shaft end. Each bearing also includes a conical sleeve in contact with an inclined surface of the inner race. A nut is threaded to the outer end of the conical sleeve such that rotation of the nut causes the centering of the shaft end within the bearing. The outer part includes a chamfer surface into which extends a shim. A screw is rotted to cause the shim to compress the outer part downwardly toward the inner race. The method for mounting the rotating part also includes the use of a stepped shoulder at one end of the housing to prevent axial movement of one of the bearing members. The opposite end of the housing does not include a stepped shoulder so as to allow easy insertion of the second bearing member.

Abstract: A wrap material spreader roll includes a smooth, cylindrical tube having spiral flights at opposite end portions thereof formed from spirally wound wires of circular cross-section, the wires having respective inner ends defined by a radially inwardly projecting portion which is received in a respective hole provided in the tube. The spreader roll is mounted to opposite support walls by respective bolts having hexagonal heads received in hexagonal bores provided in the inner races of a pair of roller bearings that are pressed into the opposite ends of the tube, the bolts having respective threaded stems received in keyhole-shaped holes provided in the walls and having nuts received thereon.

Abstract: The proposed wheel bearing has a hub 1 mounted on the preferably integral bearing shaft 4 of a wheel part 5. The hub 1 rotates on a ball bearing arrangement 2. The ball bearing inner ring or rings 3 are stressed via a washer 10 against a shoulder 6 on the bearing shaft 4. In order that the bearing shaft 4 can take greater operational forces the bearing shaft 4 has an axial bore 7, which accommodates a draw bolt 8 screwed into a plastics sleeve 13 so as to prestress the inner ring or rings 3. In this way the securing of the assembly avoids tensile stress in the shaft 4.

Abstract: A wheel bearing for wheels of motor vehicles comprises a bearing or ball roller bearing which is connected with a wheel carrier and, in a holding manner, receives a wheel hub fastened by a clamping device. The wheel hub is axially supported on the ball bearing and extends by via a tube-shaped projection to a first bearing ball in the bearing where a clamping bolt, which is axially supported on the ball bearing, stands opposite the wheel hub. This clamping bolt, by a bearing sleeve, extends to the tube-shaped projection and receives it in a torsion-proof manner by way of a centric pin. This results in the advantages that the assembly or the clamping takes place only from the exterior side of the vehicle and, in the case of a demounting, the hub part can easily be pulled out of the ball bearing after the loosening of the nut.

Abstract: A rolling bearing especially adapted for vehicle wheels or the like, has an inner part, an outer ring and, one or more rows of rolling elements rolling between the inner part and the outer ring. The outer ring has a bore with outer races for the rolling elements and a flange projecting radially outward, the flange having a locating face at one end thereof. The locating face contains holes for the attachment of the flange to the mating face of a connecting element by screws. In order to allow the holes of the flange of the outer ring to become distributed along an extremely small reference diameter on the locating face, they extend obliquely radially outward from the locating face at an acute angle with respect to the bearing axis.

Abstract: A bearing and bearing load maintaining device which provides the stiffness of a duplex set, that is, a hard preload when new, but which maintains the required internal load over an extended life to preserve alignment precision in spite of wear or differential thermal expansion. The latter is provided by a compliant spring preload configuration which takes effect only after the bearing begins to wear or otherwise unloads due to differential thermal expansion. In one embodiment, the present invention comprises a flanged bearing which applies a hard preload against an outer sleeve which in turn abuts a more conventional bearing. The outer sleeve is provided with at least one recess or shoulder at an end face. The bearing set is assembled with a spring such as a wave spring positioned in the recess or annular space at one end face of the outer sleeve.

A third plane extends perpendicular to the axis. The angle is between the first and third planes. .mu. is the coefficient of friction between the element and the bore or shaft.

Abstract: The invention relates to a bearing assembly in an especially drivable wheel hub at the associated wheel carrier of a motor vehicle. It comprises a double row angular ball bearing whose outer bearing ring is first produced as one part and is then divided by breaking it apart. The special arrangement and design of the joint ensures a close connection between the two bearing ring parts and permits a method of assembly allowing the two bearing rows to be filled with a larger number of rolling members.

Abstract: A bearing mounting system for mounting and retaining a rotatable shaft between first and second bearings mounted to first and second spaced frame members of a machine frame, utilizing commercially available bearings, with respective inner and outer races. Both bearings inner races are press fitted onto the shaft. A first bearing mount rigidly secures a first bearing outer race to one of the frame members. A second bearing mount provides for axial movement of the second bearing outer race relative to the second frame member but prevents rotation of that outer race. The second mount includes a round aperture in the second frame member through which the second bearing outer race is axially moveable, and a notch aperture adjacent to the round aperture, and a clamp removably clamped to the outer race and moveable therewith. The clamp is axially but not rotatably moveable within the notch aperture in the second frame member.
