Configuring the drive element hub
The new output element is mechanically connected to the
actuator shaft via a hole with feather key groove. This
connection should be designed so that the nominal torque and
any possible max. output torque is transmitted securely. The
drive element must be mounted securely on the output drive
shaft with suitable measures to prevent axial shift. For the new
drive element, you can use the current mechanical stops.
The following parameters must be observed:
