Abstract

1295500 Rolling gears TELEDYNE Inc 21 Dec 1970 60690/70 Heading B3M Apparatus for roll-forming a pre-hobbed gear-wheel W comprises a rotatable tool 54 on one side of the gear-wheel and supporting rollers 34 and 36 on the opposite side, the rollers bearing on discs 96 and 98 between which the gearwheel is clamped. The disc 96 is formed with a central spigot which passes through the gearwheel (Fig. 2, not shown) and co-operates with the disc 98. By moving the disc 98 longitudinally the gear-wheel is unclamped. The two discs are mounted on a carriage 56 which'is horizontally movable so that the discs can be shifted between a rolling position and a feeding position. To start rolling, the carriage is moved to the left, Fig. 3, and a blank is raised by a fluidpressure ram 120 to a position between the discs 96 and 98. Further blanks are prevented from moving by a roller 120 associated with the carriage 56. The carriage then moves the clamped blank between the tool and the rollers 34 and 36. The rollers can either be retracted to allow location of the workpiece in a rolling position, and then be raised to exert the rolling force, or the rollers can be held in position and the workpiece be drawn slowly between them. A safety device can be used to stop the machine if a faulty blank causes a delay in the feeding procedure. A shoot 126 guides finished blanks away from the apparatus. The carriage 56 may be mounted on stiff springs to accommodate slight vertical movements of the gear-wheel.
