Configuring the drive element hub
The new drive element is mechanically connected to the drive shaft via a hole with feather key
groove . This connection must be constructed so that the rated torque and any possible output
torque is transmitted accurately. The drive element must be mounted securely on the 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:
