An apertured bearing of a hardened plastic material is enclosed within the body and at one end has an annular stop shoulder bearing against the stop flange and defining a cylindrical extension of reduced diameter extending outwardly of the body adapted to journal a shaft. In a modification, an annular groove in the cylindrical extension outwardly of the stop flange receives a snap ring to restrain the bearing against endwise movements relative to the body.

Abstract: For a simple adjustment, suitable for automation, of the axial play between the rotor (1, 2) and the stator (5 to 8) of a miniature electric motor, at least one bearing (3) is axially moved relative to its bearing sleeve (51) in the end bell (5) and is fixed in its adjustment position by deformation of the bearing sleeve in a form-locking manner. For axial fixation, especially when used for drives with large axial loads, a thrust shoulder (511, 512) is formed after the axial play is adjusted for the axial contact of the adjusted bearing (15) from the bearing sleeve (51) by hot molding, ultrasonic heat deformation. Alternatively, precut tabs may be formed on the sleeve by embossing to form a thrust shoulder.

Abstract: In a bearing assembly for a roll neck in a rolling mill, an inner seal ring is mounted with an interference fit as by shrink fitting, on an end portion of an inner bearing component, e.g., the sleeve of an oil film bearing or the inner race of a roller bearing. The end portion of the inner bearing component is suitably dimensioned and configured to deflect radially inwardly under the influence of hoop stresses developed as a result of the aforesaid interference fit, thereby causing the inner seal ring to be inclined towards the roll end face. The end portion of the inner bearing component has an outer diameter which is larger than the outer diameter of the remainder of the inner bearing component.

A sleeve (23) composed of material having a sufficient degree of elastic deformability to absorb vibrations is interposed between the outer face (24) of the bearing (7) and the inner face of the tubular support (8). The electric motor is intended in particular to equip propeller-type fans and is primarily applicable to direct-current motors of the electronic commutation type.

Abstract: Plain bearings, particularly thin-walled plain bearing liners, are provided with radial projections for fixing and as an aid to assembly, e.g. with lugs, on the outer side of the outer part of the bearing, without using the whole thickness of the outer part of the bearing, so that the inner surface of the outer part of the bearing, which carries the functional layer, remains along its whole length cylindrically curved and smooth. Such outer projections may be formed on a part of the thickness of the outer part of the bearing by radial shaping of the material. This may be made on the joint face of bearing liners or one one or the other of the axial end faces of bearing liners or bushes or also on any desired place of the outer peripheral surface of the outer part of the bearing.

Abstract: This invention concerns a flanged half-bearing for motor applications. This half-bearing is of the type consisting of a semi-cylindrical shell, provided with half thrust washers suitable for the axial registering of the shaft, and reacting, therefore, to axial loads.The connection between semi-cylindrical shell and washers is obtained by hooking appended parts, substantially in convex prism form, present on each washer, between corresponding cavities arranged on the curved edges of the shell. Based on the angle position of the cavities, in relation to the axial plane of symmetry of the shell, and based on the shape of the cavities themselves and of the relative appendages, providing a slight interference in the coupling phase between shell and washer, and taking advantage of the flexibility of the shell, when mounted on the support, a coupling between shell and washer is obtained, which is stable before mounting in place and movable, circumferentially and axially, when mounted on the relative support.
