Drive for driving e.g. finger prosthesis, has clutch including friction elements, which are frictionally connected with each other and transferrably moved relative to each other at torque and include different materials at friction surface

摘要

The drive (1) has a clutch (15) connected with an electric motor (2) and an output shaft via a drive shaft (4). The clutch limits a rotational torque, which is transferred from the drive shaft to the output shaft. The clutch includes friction elements (13), which are frictionally connected with each other and transferrably moved relative to each other at the rotational torque. The elements include different materials at a friction surface. The friction surface is made of carbon. One of the elements is attached to the drive shaft, and axially displaceably arranged on the drive shaft.
