摘要： A wrought or powder metal gear preform is mounted for rotation about a first axis and then driven in meshing engagement with a roll forming die supported for rotation about a second axis transverse to the first axis. The roll forming die includes a helical worm thread that moves radially as well as axially across the face of the preform teeth to displace the material of the preform. In the case of a powder metal preform, displacement of the material acts to densify the teeth, whereas in the case of a wrought preform the gear teeth are burnished. The preform and roll forming die are separately driven to control densification.

摘要： In a vehicle wheel hub bearing unit and brake arrangement, the bearing forms a rotating radial flange (11) adapted for securing to a radial flange (12) of a brake member and rotate fixedly therewith. The brake member flange (12) is located substantially in the same radial plane of the bearing flange (11) and secured directly to the peripheral portion thereof. A form or splined connection (13, 14) couples the flanges (11, 12) in non-rotatable manner. The hub bearing flange (11) has a shoulder (15, 135) radially protruding from the axially inner side thereof so as to provide an axially inner abutment for the brake member flange (12). The brake member flange (12) is axially restrained from axial outward motion by the wheel rim (16, 21).

摘要： A process and device for manufacturing cylindrical hollow bodies out of a blank through cold forming using roll cylinders is provided. The axes of the roll cylinders in this process are essentially adjusted parallel to the axis of the workpiece and execute, essentially radial to the workpiece, an oscillating, reciprocating movement. This reciprocating movement is executed in such a manner that in the upper oscillation stop the roll cylinders and the workpiece preferably just barely touch each other without the application of force, and in the lower oscillation stop preferably dip into the surface of the workpiece up to the desired infeed depth in order to achieve the demanded external diameter of the workpiece. With this process the very high static pressures required for press roll machines can be avoided, which results in small and light engine frames, and simultaneously makes it possible to machine workpieces with flanges directly up to the flanges.

摘要： A machine (20) for rolling power transmission formations in a workpiece includes a base (20) having a lower end (24) for providing support thereof in an upwardly standing orientation. The base (22) includes a pair of spaced base portions (30) and a rear connecting base portion (32). The spaced base portions (30) project forwardly from the rear connecting base portion (32) to define a vertically extending workspace (34) and are secured to each other and to the rear connecting base portion by tie rod assemblies (38, 40, 42). Headstock and tailstock spindle supports (48,52) cooperate to rotatably mount the workpiece about a rotational axis (A) of the machine. A pair of vertically movable slides (66) respectively mount a pair of forming racks (68) and are respectively mounted by the spaced base portions (30) on opposite sides of the rotational axis (A) about which the workpiece is rotatably supported such that the forming racks oppose each other and roll power transmission formations in the workpiece during vertical movement in opposite directions.

摘要： External teeth are formed on an annular metallic workpiece centered on a workpiece axis by fitting the annular metallic workpiece to a die with internally directed teeth to form axially open and radially closed spaces between the workpiece and the die at the teeth and axially pressing a pair of closing members oppositely against the die and workpiece to axially close the spaces. Then the fitted-together die, closing members, and workpiece are engaged between a pair of tools that are pressed together along a pressing axis generally parallel to the workpiece axis. The die, members and workpiece are synchronously rotated about the workpiece axis while the tools are rotated about respective tool axes each forming a small acute angle with the workpiece axis so as to locally compress the workpiece axially between the tools to deform the workpiece into the spaces. A bearing supports the die and workpiece while the workpiece is compressed between the tools.

摘要： An internally toothed member is shown suitable for use as a clutch drum in an automatic transmission. The internally toothed member has the shape of a cup with an open end and a central axis. The cup-shaped member has first internal teeth extending in the axial direction and second internal teeth extending further toward the open end of the member than the first internal teeth. The internal teeth are each formed on an inner circumferential surface of the cup-shaped member in each of a plurality of locations spaced in the circumferential direction. Also, a groove for receiving a snap ring is formed in the second internal teeth closer to the open end than end faces of the first internal teeth facing the open end. Because the first and second internal teeth are formed projecting radially inward, they do not lower the rigidity of the internally toothed member. Also, because it is not necessary to fix a cylindrical member to the outside of the internally toothed member for reinforcement, working man-hours can be reduced and it is possible to lower the cost of the internally toothed member.
摘要翻译：显示出适合用作自动变速器中的离合器鼓的内齿构件。内齿构件具有开口端和中心轴的杯形。杯状构件具有沿轴向延伸的第一内齿，并且第二内齿比第一内齿更向前延伸到构件的开口端。内齿分别形成在圆周方向间隔开的多个位置的杯状部件的内周面上。此外，在第二内齿形成比接近开口端的第一内齿的端面更靠近开口端的用于容纳卡环的槽。由于第一内齿和第二内齿形成为径向向内突出，所以它们不会降低内齿构件的刚性。此外，由于不需要将圆筒形构件固定到用于加强的内齿构件的外侧，所以可以减少工作时间，并且可以降低内齿构件的成本。

摘要： A method for the manufacture of a machine part with external teeth, particularly a starter ring or gear part, by spin forming of a circular blank and inductive heating which makes it possible to form high-quality tooth systems on an outer area of a cylindrical part. A circuit metal blank is fixed between chuck jaws in a spinning device and an end region is heated by at least one induction device and passes into a plastic state. Tools are then infed on either side of the chuck jaws and a forming operation, which includes material upsetting, is performed with a gear-cutting roll to form the external teeth. This is followed by induction heating of the teeth.
