Abstract: A method for assembling bearing rings in an elongated sleeve member consisting of the steps of forming a roller shell with three sections of varying wall thicknesses separated by angular circumferentially extending shoulders, deforming the shoulder between the middle section and one end section to form a ring-shaped radially, inwardly directed projection by axial displacement of the shoulder. A bearing ring is inserted in the interior of the shell member so that one axial end face engages the first radially oriented projection formed and deforming the shoulder between the middle section and the other end section to form a second radially inwardly directed projection by axial displacement of the shoulder which confronts the opposite axial end face of the bearing ring.

Abstract: Axially-extending troughs in a bark of an internally threaded collar receive setting balls of a driver that apply a torque to the collar through the balls bearing on the walls of the troughs. At a predetermined preload, the balls fail the bark and plow through it to develop circumferential furrows, and the torgue application on the collar ends. A second torquing which balls at a different axial position fails the bark again at the same pre-load to compensate for any relaxation after the first torque application.

Abstract: The invention relates to a can-type housing made of metal, as a semi-finished product, such as is used, for example, for electrolytic capacitors. Furthermore, the invention relates to a process and a device for reducing the diameter of and flanging such a can-type housing.

The invention improves the conventional measures by rewidening under dry conditions the can-type housing pre-widened under wet conditions. According to the process, the can-type housing provided with the housing widening is then closed from the can edge axially downwards so as to reduce its diameter, this process step being supplemented, in addition, by a further flanging step carried out in the same device.

Abstract: During assembly of a brake booster employed in a hydraulic brake system of an automotive vehicle, the two casing shells of the booster are moved relative to each other by compressing the elastic seal disposed between the two casing shells an amount until a predetermined distance is achieved between the surface at one casing shell used to mount a master cylinder on the booster and the force-transmitting end of the push rod of the booster. In this position, the two casing shells are then operatively connected to each other to maintain the predetermined distance. This method of assembly and the arrangement for implementing the method simplifies the manufacturing of a brake booster.

Abstract: A method of fastening a first shell to a second shell to form a housing. The first shell which has a radial wall with a projection adjacent its peripheral surface is positioned in a fixture. A bead on a diaphragm assembly is located in a groove in the projection. The opened end of an annular wall on the second shell is placed around the bead and peripheral surface. The second shell is moved toward the first shell until the peripheral surface contacts a stop on the second shell. Thereafter, the opened end of the second shell is crimped into engagement with the radial wall to hold the peripheral surface in engagement with the stop. The fixture is rotated while a tool is brought into contact with the annular wall. The tool deforms the wall by creating a rib that radially compresses the bead into the groove and seals the housing.
