Each ball bearing is partially exposed out of the first slide member at a corresponding oval portion of the slot. The second slide member is slidably engaged with the exposed portions of the ball bearings. Thus the first slide member can be reliably moved relative to the second slide member.

Abstract: A tripod joints includes a joint outer part and a joint inner part. The joint inner part has a tripod star with ball pins, which transmits a drive torque from the joint inner part to the joint outer part via a pressure element and via rolling bodies which are arranged between the joint outer part and a running surface of the pressure element. The running surface of the pressure element is curved in the rolling direction of the rolling bodies. The force may be distributed more uniformly between the rolling bodies when large drive torques are intended to be transmitted. The tripod joint may be suitable for the displaceable and pivotable driving connection of two shaft ends, e.g., in conjunction with drive trains or half shafts of motor vehicles.

The backup member has angled surfaces such that ends of the rollers are closer to the angled surfaces than are intermediate portions of the roller. The two side members of the two-piece bearing race may be spread apart such that the angled surfaces of the backup member direct the side members of the two-piece bearing race toward the rollers to decrease the roller clearance and to create a preload.

Abstract: A linear roller bearing includes a bearing cage retaining parallel rollers in a linear configuration. Side portions of the bearing cage extend laterally to form a mechanical interlock with an adjacent similar bearing cage such that, when two or more bearing cages are positioned about an inner tubular member for guided axial movement relative to a coaxial outer tubular member, the mechanical interlock prevents relative axial movement of the adjacent bearing cages. Adjacent bearing cages may be identical or of differing configuration provided a mechanical interlock preventing relative axial movement results. The linear roller bearing may include inner and outer races, or, alternatively, the tubular members may be formed with integral raceways.

Abstract: A guide for a high speed steel rolling mill comprises two rolling members, between which the work product passes mounted for rotation on a base member. Each roller has a frusto-conically shaped bearing recess formed therein and each guide roller is mounted on a mating, frusto-conically shaped projection which protrudes from the base member. Each of the projections has a central oil duct which serves to feed a lubricating oil under pressure into the frusto-conically shaped space between the roller and its mating projection. The lubricating oil serves to form a film between the stationary projection and the rotating guide roller. Because of the conically shaped mating surface, the lubricating oil tends to “lift” the guide roller from the surface of the supporting base. Each rolling member is provided with a vane structure to permit the rolling member to be prespun by the impingement of a cooling fluid on the vane surface thereof.

Abstract: The Two Axis Track Roller is in the form of two sealed bearings mounted to a single stud which allows the device to carry loads in two dimensional axis. In this way the device can carry a load along a track as well as guide along a track wall. When used in pairs the device can be "pre-loaded" which allows for precise guiding of linear motion. The conventional bearing used provide internal balls and rollers which ride on their internal precision ground and hardened surfaces. The external bearing surfaces thus can ride on non hardened track surfaces whose precision is dictated only by the application requirements. Since the bearings are sealed the bearing balls and rollers do not come in contact with environmental contaminants so bearing life is increased.

Abstract: A drive system for the conversion of a rotary motion into a linear motion contains a belt drive similar to a block and pulley system, and a system of a rack and pinion that is driven synchronously with the belt drive. The pinion and the rack are adjusted with respect to each other such that the teeth of the pinion engage with relatively large play in the rack. When driving under normal load, the drive takes place without loading of the rack and pinion system by the belt drive, so that the reversal backlash and the play of the rack and pinion system remain without effect on the displacement motion. When an overloading of the moving part and a corresponding stretching of the drive belt occur, the tooth flanks of the pinion and of the rack are supported against each other and in this manner prevent tearing or overloading of the drive belt.

Abstract: A press die set includes a hollow cylindrical guide bush mounted on a punch holder, a cylindrical retainer received within the guide bush, and a columnar guide post vertically mounted on a die holder and received within the retainer. First right angle grooves are formed on the outer surface of the guide post parallel to a longitudinal axis of the guide post. First planar surfaces are formed on an outer surface of the guide post parallel to the longitudinal axis of the guide post and perpendicular to a radius of the guide post. Second right angle grooves are formed on the inner surface of the guide bush parallel to a longitudinal axis of the guide bush. Second planar surfaces are formed on the inner surface of the guide bush parallel to the longitudinal axis of the guide bush and perpendicular to a radius of the guide bush. Cross roller bearings are positioned between the first and second right angle grooves, and plain roller bearings are positioned between the first and second planar surfaces.

In accordance with the present invention, the pockets have a first size in the transverse direction slightly larger than the characteristic size, e.g., diameter in the case of balls, of rolling members and a second size in the longitudinal direction substantially larger than the first size so that the pockets are generally in the shape of a slot with either a circular pocket provided in a central portion of the plate or the second size being large enough to accommodate two balls with a separator therebetween.

Abstract: Rolls of roller bearings have in their axial middle portion a load-transmitting peripheral surface and on their axial end portions there are respective radially projecting and space-maintaining peripheral surfaces. Therefore, only the space-maintaining peripheral surfaces of adjacent rolls contact one another.

Abstract: A bearing construction interposes the coils of one or more coil springs between bearing surfaces. In one embodiment a bearing coil spring is wrapped around a shaft several times. The bearing coil spring may be freely mounted on a more substantial race coil retainer centered on the shaft. In another embodiment toroidal coil springs separated by disc races extend circularly about the shaft. In linear bearing construction, the bearing coils are in planes parallel to the line of shaft movement. Other embodiments of the invention involve disengageable shafts having complementary centering end-faces accommodating misalignment through the yield able action of the bearing spring coils, shafts and housings having non-circular cross-sections, and shafts and housings not having completely complementary surfaces to enable interference fit and positional control.
