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.
