    摘要: A process and apparatus for forming a cage part, for a ball bearing, wherein the cage parts are annular with alternate flat portions and ball receiving recesses. The cage parts are formed by pressing the rings from cage material such as steel. The flat portions are formed with axially extending rivet pins or holes for receiving the rivet pins of another cage part, in order to enable fastening of the cage parts together. The rivet pins are formed by pressing operation at the time as forming the cage part, by the flowing of the material of the cage part into recesses in a die.

    摘要: A worm gear has a threaded spindle and a threaded nut, the thread on the spindle or the nut or on both having a profile such that the transition regions connecting the thread crown surface to the thread flanks are rounded, as is the crown surface itself. Further, the spindle thread and nut thread are intermeshed with axial and radial play such that radial forces exerted under torque loading are transmitted only by areas of the crown surface, which transmitted forces are supported by the respective areas of the opposing groove bottom. Smooth functioning is ensured even when the threaded spindle occupies a position of maximum inclination relative to the nut.
