Abstract: Apparatus is described for cold forming cylindrical metal blanks into parts having a central body and radial extensions, such as universal joint spiders and constant velocity universal joint tripod members. Die sectors of shortened axial height in their radial forming and extrusion zone are mounted for quick fastening and release, for example by dovetail connections to die carriers which are in turn mounted on rams displaceable along inclined converging slideways. Guide bushes are provided at the entrance to the through cavity corresponding to the central body and guide a cylindrical blank along the axes of coaxial punches fixed respectively to the plunger and column on the table for restraining plastic flow of blank metal towards the central cavity and then to the radial cavities.

Abstract: An oscillating bearing support for supporting an intermediate shaft of a power transmission with universal joints particularly in motor vehicles. An inner sleeve supports the shaft for rotation therein. An outer support sleeve is fixed to a fixed support. The facing surfaces of the inner and outer sleeves are provided with adjacent circular grooves generally concentric with the axis of the shaft in its rest position. An elastomeric toroidal member is provided wth ribs cooperable with the grooves of the sleeves and concentric with its center line. The toroidal member is fitted on the inner sleeve and compressed between the inner and outer sleeves. Radially projecting portions at the ends of one of the sleeves cooperate with plain cylindrical portions at the ends of the other sleeve for axially retaining the inner sleeve relative to the outer sleeve. The toroidal member may be formed in segments. The grooves in the inner and outer sleeves may be screw threads.
