Fig. 1: Functional principle of toothed belt drive with fixed toothed belt
The axis converts the rotary motion of the mounted motor into a linear motion of
the cantilever or slide. The toothed belt drive converts the torque of the motor
into a feed force. The linear movement of the cantilever or slide is accurately
guided by the guide. The integrated cover strip prevents abraded particles from
penetrating the immediate vicinity of the drive. The clamping unit is used for
holding loads at standstill or for emergency braking in the event of a power
failure. Sensors and displacement encoder enable query of end positions, refer-
ence position and intermediate position.
