Abstract: A bearing assembly is disclosed which addresses the problem of axially retaining a bearing journaled onto a shaft within a casing in an axially compact and technically economic and reliable way by first mounting a retaining plate (6) onto an outer race of the bearing (1). The mounting can be achieved by press fitting onto a shoulder so that the retaining plate can rotate relative to the outer race. The bearing is then journaled onto a shaft (4) and inserted into a compact casing (3) so that the outer race is guided into a housing (2) formed in an end wall of the casing (3). The retaining plate can then be rotated as required to align fastening bosses (7) with holes (8) to be engaged by screws (9) so that the retaining plate us urged axially against the outer race.

Abstract: A Tee nut and method of manufacture is provided which Tee nut includes a flange and a hollow barrel extending from the flange. The flange is general circular and has a pair of pawls extending upwardly therefrom, each of which terminates in teeth for engaging a base member. The barrel has an end portion proximal to the flange and a distal end portion. The proximal end portion has internal female threads and the distal end portion has a smooth unthreaded inner surface. The wall thickness of the distal end portion is thinner than the wall thickness of the proximal end portion, and the outer wall diameter is essentially constant for the length of the barrel. The barrel is formed first as an elongate member extending from a strip of material initially having a constant inner diameter and an outer diameter of the proximal portion greater than the outer diameter of the distal portion, with the distal portion having a wall thickness thinner than the wall thickness of the proximal portion. The outer diameter of the distal portion is increased to the same diameter as the outer diameter of the proximal portion while maintaining the same wall thicknesses of both the distal and proximal portions. The internal surface of the proximal portion is threaded with threads terminating at the distal portion and having a lead angle of at least about 80.degree.. The terminal end surface of the distal portion is essentially planar and parallel to a flange.

Abstract: A method of manufacturing an improved screw washer, an improved screw washer, and an improved mold for fabricating the improved screw washer. Using a selected metal plate having a thickness thinner than a nominal height demanded for a nut, the invention primarily aims to form an improved screw washer incorporating a nut satisfying the demanded height. The invention is to provide an improved method of manufacturing an improved screw washer, the improved screw washer, and an improved mold for fabricating the screw washer. Particularly, using this improved mold, the improved screw washer can easily be manufactured, where the above-identified nut is solidly bonded with the metal plate without being disengaged therefrom, and yet, a sufficiently lengthy tapped hole is formed. Structurally, a nut is formed in the state being continuous to a metal plate after punching out part of the metal plate. The nut is further punched in order that a punched hole having a diameter narrower than an inner diameter of a tapped hole can be formed in the center of the nut, and finally, the tapped hole is formed in the nut in the manner being coaxial with the punched hole.

Abstract: An apparatus makes self-piercing nuts from blanks (11) each having a cylindrical pilot portion (13) which has a raw unopened and unthreaded bore (12) and an end surface serving as a punch. The pilot portion surrounded by a rim (14) extending along a periphery a nut body, and an annular groove (15) is present between the pilot (13) and the rim. The apparatus has a punching die which has a boring punch (33) and a first cylindrical insert (35) fitted on the punch serving to open the bore (12). The boring punch has at its basal portion a tapered annular wall (34), and the cylindrical insert (35) having at its end surface an annular lug (36) capable of fitting in the annular groove. The tapered wall (34) radially expands an end of the pilot portion, so that its peripheral wall is forcibly slanted in a radial direction and an annular edge (13a) of the peripheral wall is stopped by an inner periphery of the annular lug (36). Due to this feature, the apparatus can mass-produce the self-piercing nut of an accurate dimension which can smoothly punch an opening trough a metal plate, and an invariable and sufficient clinching force is ensured to the self-piercing nut.

Abstract: A sleeve constructed of a deformable material has a bore of such diameter as to permit sliding receipt over the forming threads on the end portion of a tap and locating about a reduced diameter unthreaded portion of the tap. The tap threads are constructed to initiate forming from the inner part of the tap shank and finish at the shank end. The sleeve is compressed to conform to the tap reduced diameter portion and moved to and off the threads as the tap is rotated forming threads on the tap inner wall. Reverse rotation of the tap to remove it from the threaded sleeve is not required.
