Patent DE-19700871-A1 (DE)
Title: Producing hub of road vehicle steering wheel
Inventor: SZLAVIK JOHANN
IPC: B62D1/10
Filed: 1997-01-06
Abstract: A bowl-shaped cavity is formed in the plate at the hub position by a deep drawing process. A circular hole (4) is stamped in the centre of the base of the cavity. The base (3) of the cavity is pressed back until it evolves completely into an inner side wall of the same height adjacent to the outside side wall (2) of the cavity. The outer and the inner side walls are then pressed together and calibrated in order to form the tubular hub. Before the stamping of the hole, the base of the cavity, leaving the outer side wall as it is, is partly pressed back, so that a circular trough is formed on the outside of the cavity.

Filed: 1997-02-20
Abstract: The present invention relates to a disk (1), in particular the front disk of a filter element, comprising an opening (10), fitted with a seal (2), by means of which the disk (1) can be pushed onto a connecting sleeve (3) in a sealing manner. The disk (1) is made of a thermoplastic plastic material and the seal (2) is a ring made of plastic fleece or plastic felt, which is connected to the disk (1) on one of its flat sides by means of a thermowelded bond (21) provided for at a radial distance from the opening (10). On the side of the disk having the thermowelded bond (21), said disk (1) has a continuous, raised circular thickening rising from the plane of the disk (1). The height of said thickening is at least one third of the height of the unstressed sealing ring (2) and the welded bond (21) between the sealing ring (2) and the disk (1) is spatially limited to the surface of the thickening. According to the invention, the disk is characterized in that the thickening is configured in the shape of a weld bead (13) arranged continuously at a radial distance around the opening (10) in the disk (1), that when the disk (1) is pushed onto the connecting sleeve (3) the sealing ring (2) is sealed in the area (23) between the connecting sleeve (3) and weld bead (13), and that the sealing effect is achieved by the sealing area (23) created by upsetting and thus compressing the material of the sealing ring (2) radially towards the exterior.

Patent DE-19713077-A1 (DE)
Inventor: KAPPAUF HORST DIPL ING
IPC: H02K3/50
Filed: 1997-03-27
Abstract: The invention relates to a device for supporting the first part (1) of a stator of an electric machine, especially a turbo generator, on a second part (2) of the stator. The first (1) and second (2) parts are arranged at a distance from each other and surround the rotational axis of the rotor shaft at least partially in the direction of rotation. The two parts (1; 2) are supported on each other by means of single-piece support elements (4) at at least three points distributed around the rotational axis. These support elements each have a material strip (5) between their ends, said material strip being bent in a single plane, so that the distance between the two parts (1; 2) can be altered in the axial and radial direction of the turbo machine by distorting the bend of said material strip (5). The support is rigid in a tangential direction due to the stiffness of the material strips (5) transversally to the flexural path. These bent material strips mean that the inventive device is space-saving and economical to produce. It is also considerably simpler to assemble than other, known support devices.
