Shaft-Side Clamping Element - Siemens SIMOTICS T-1FW3 Configuration Manual

5.4.3.2

Shaft-side clamping element

Various mounting options using clamping elements are shown in this Chapter.
Siemens AG in cooperation with RINGSPANN GmbH has developed various clamping
system solutions to ensure secure, friction-locked connection of torque motors to cylindrical
machine shafts - with the following objectives.
● Safely and reliably transmitting the torque
● Precisely centering the torque motor on the machine shaft
● Avoid inadmissible deformation to the torque motor components
● No distortion caused by different temperature changes in the torque motor and in the
machine shaft
● Simple mounting
● Simple removal, even after longer periods of operation
Mounting using suitable clamping elements is explained in the following.
