Roller gear cam drive & Hirth coupling Durable　 1 million rotation No adjustment A large number of achievements for transmission case machining Roller gear cam drive with an excellent indexing motion characteristic Optimum cam curve makes the speed and durability Roller gear cam drive provides smooth acceleration and deceleration movement according to the machine characteristic by adapting a cam curve. In case of worm gear In case of worm gear drive, the worm wheel rotation angle is represented by a rectilinear velocity-diagram as shown in the sketch below, also worm gear drive needs time for braking. To secure smooth acceleration and deceleration (start/stop), an expensive servo motor (NC additional axis control) must be required.
