Drive for a swivel arm, in particular robot arm

摘要

The invention relates to a swivel drive for a robot arm. This swivel drive has an axially parallel double cylinder with pistons and piston rods moving in opposite directions. Connected to the free piston-rod ends is a drive chain which runs around a drive pinion. Drive chain and drive pinion are situated in a chain housing which, together with the double cylinder or its cylinder housing, forms a fixed bearing arm for a swivel arm or itself forms a swivel arm. This produces a compact and slim design with a high torque for robotics. <IMAGE>
