ABSTRACT:
A machine for rolling hypoid gears, particularly pinions having a stem projecting from one side, in mesh with a tool in the form of a hypoid ring gear. Work pieces are provided at a preliminary loading station with their teeth located in a precisely predetermined angular position. From this station they are transported into alignment with a rotary work spindle which at this time is fixed against rotation in a random position. The gear-like tool is secured to a spindle which is fixed in a precisely located angular position so that the teeth of the gear and tool are in proper angular alignment. The gear is fixed on the work spindle and the work and tool spindles are relatively moved to mesh the gear and tool, after which both spindles are released for rotation and one spindle is positively driven in rotation.
