Perfect protection of servo axes
Mechanical torque limiting clutches from Mayr have long been used in the servo drives of machine tools, and have proven their worth thousands of times. The latest generation - the EAS-smartic - has been specially adapted to the requirements of machine tool axes.
The outer diameter equals that of a standard shaft coupling, and is only
10-15mm longer in total length. This results in a very low mass moment of inertia. Hardened components using the ball-detent principle and special cup springs provide extremely high torsional rigidity. All components have been dimensioned so that reliability does not come at the expense of performance.
Another new feature is the simple torque adjustment. If no specific value is required, the clutch is preset to approximately 75 percent of the maximum torque. A reference marking and torque indication on the clutch show the set value directly. In only a few simple steps, the torque can be set to another required value. Torque is transmitted - backlash-free - until the preset torque is exceeded, at which point the clutch disengages and the torque immediately drops.
