Abstract: An improved flexible support for a steady bearing in rotational contact with the surface of a shaft allows the bearing and housing to substantially track the contact surface of an impeller shaft when the shaft is subject to elastic deflection during operation. The flexible support employs a flexible disc pack, which is comprised of a plurality of thin, flexible disc elements in a stacked arrangement. The disc pack is mounted to a support ring and is also mounted to the bearing housing such that the bearing housing and other bearing elements are capable of deflection to substantially align with the axis of the impeller shaft when the shaft deflects.

The bearing further includes a second bearing flank including a second bearing surface having a shape in cross-section defined by a second arc having a second radius extending from a second surface axis. The first bearing flank and the second bearing flank are structured and adapted such that the first bearing surface and the second bearing surface together in cross-section form a concave shape, and such that the first bearing surface and the second bearing surface are non-concentric. Alternatively, the first and second bearing flanks can be replaced by roller bearings.

Abstract: A floating bearing system comprising a bearing supported in a clearance fit within a bearing bracket, for example for use in fractional horsepower shaded pole type electric motors. The bearing system is self aligning, to compensate for deviations in the axial alignment of the rotor shaft. A rotation lock restrains the bearing against rotation within the bearing receptacle while allowing the bearing to settle into proper alignment with the rotor shaft by automatically shifting the pitch of the axis of the bearing. In the preferred embodiment the bracket is composed of an engineering plastic and the bearing is composed of a high performance plastic polymer, so that the bearing system is non-lubricating. In the preferred embodiment the bearing bracket is provided with retaining fingers which hold the bearing in place during the assembly and working life of the motor.
Abstract: A shaft bearing system having a housing including a spherical collar for the shaft. The shaft bearing is made up of a cage (19) into which the spherical collar (20) is inserted. The cage is installed in a recess (18) in a housing (16); a sleeve (21) is arranged in the interior of the spherical collar, and an axle stub (22) is inserted into the shaft bearing. The rotational movement preferably takes place between the sleeve (21) and the axle stub (22). The use of the spherical collar in a shaft bearing made up of a cage and a guide bushing has the advantage of greater flexibility in selecting the material or materials from which the housing and the rotatable component installed therein may be formed. The shaft bearing of the invention is particularly useful for accommodating a centrifuge rotor (10) in a centrifuge housing (16).

The reduction gear includes a pinion gear turned by the steering shaft, a steering gear engaged with the pinion gear and fixedly mounted on a lever shaft, which is combined with the steering lever, and a gear case housing the pinion gear and the steering gear. The lever shaft has a first end portion supported in a bearing held on the gear case. The bearing permits the lever shaft to be turned therein. The lever has a second end portion supported in a bearing hole that permits the second end portion to be shifted in the back-and-forth direction. The second end portion of the lever shaft is biased by a spring so as to press the steering gear against the pinion gear so that no backlash is formed between the pinion gear and the steering gear.

Thus, by tightening the stopping screw 8, the periphery surface 5a of the outer conical portion 5 is pressed with the inner circumference 7a of the inner conical portion 7 and the contact surface pressure between the inner circumference surface 4b of the outer race 4 and the spherical surface 9a of the inner race 9 is increased, so that by regulating the tightening force of the stopping screw 8 the sliding torque of the spherical bearing is easily adjusted.

Abstract: A motor unit for operating a functional member of a vehicle includes a motor portion and a gearing portion. The gear portion includes a wheel gear intermeshed with a worm gear driven by a shaft. The shaft is supported by a plurality of mounts. At least one of the mounts and the shaft defines a complementary contacting surface having a bowed cross section.

Abstract: A unique bearing system for particular use in scroll compressors includes a pair of spaced tapered portions. Upon misalignment of the shaft, the tapered portions contact the bearing and provide surface contact between the shaft and the bearing. This allows the bearing to more easily distribute the loads that are placed onto the bearing during shaft misalignment.

Abstract: A ball and socket bearing assembly adapted to receive the vertical post of a rudder installed in the stern of a boat. The assembly consists of a molded journal box having a spheroidal cavity therein defining a socket in which is nested a ball-like bearing formed of UHMW polyethylene or of a material having similar non-stick properties, the post passing through an axial bore in the bearing. The assembly is produced by placing the preformed bearing in a mold to create an annular space between the bearing and the inner wall of the mold. This space is then flooded with a curable liquid resin monomer whereby when the monomer is polymerized and rigidified, it does not bond to the non-stick bearing. The bearing is therefore free to rotate in the cavity and align itself with the rudder post regardless of the degree to which the post deviates from the vertical as a result of hydrodynamic or other forces imposed on the rudder.
Abstract: A scroll compressor of the type having a cantilever mounted shaft is provided with a carbon crankcase bearing. Further, the bearing mounting the eccentric pin within the orbiting scroll is also formed of a carbon material. The bearing mounting the lower end of the shaft is further formed of the carbon material. The carbon bearing insures that the shaft will be quickly worn away should there be shaft misalignment.
Abstract: A rotating shaft of a rotating machine is supported at its both ends by bearing bushes which are held in a frame of the rotating machine. The outer periphery of the bearing bush is rounded and held with a rounded surface formed on the frame, so that the rotational axis of the shaft and the bearing are self-aligned by rotation of the bearing bush. The inner bore of the bearing bush rotatably supporting the shaft therein is shortened by forming a relief bore, the diameter of which is larger than that of the inner bore. Because of this bearing structure, a natural vibration frequency of the shaft varies less, and, therefore, the rotating machine can be easily designed so that harmful noises due to the natural vibration are sufficiently suppressed.
Abstract: A bearing assembly comprising an outer non-rotating sub-assembly including an outer housing including a cylindrical bore, and an outer bearing including an outer cylindrical surface engaging the cylindrical bore of the outer housing, and a bore defined by a spherical inwardly facing bearing surface, and an inner rotating sub-assembly including an inner bearing including an outer surface defined by a spherical outwardly facing bearing surface engaging the inwardly facing bearing surface of the outer bearing, and an internal cylindrical bore adapted to receive a rotating member.

Abstract: A slide bearing has a bearing bore for accommodating a shaft acted upon at least temporarily by a radial force. At least one bearing end of the slide bearing has at least one chamfer for preventing a contact between the shaft and the slide bearing and/or for facilitating the supply of the slide bearing with lubricating medium. In a preferred embodiment, in which the radial force acts essentially in a predetermined direction onto the shaft, at least one chamfer is provided on an unstressed side created because of the predetermined force effect, which chamfer is larger than a chamfer on a stressed side situated opposite the unstressed side. By means of the chamfer or chamfers, the danger of contact on the unstressed side caused by a bending of the shaft is reduced and the supply of the slide bearing with lubricating medium is increased without significantly reducing the bearing length on the stressed side which essentially carries the bearing load.
