Joint arrangement for use in robot arm, has spring unit for pre-tensioning bearing, where spring unit is arranged and designed such that mechanical tension is produced between two end units in direction of connection via intermediate unit

摘要

The arrangement has two end units (10, 12), and an intermediate unit (32) connecting the end units via a flexible bearing i.e. needle bearing. A spring unit i.e. polyurethane compression spring (34) is provided for pre-tensioning of the bearing, where the spring unit is arranged and designed such that a mechanical tension is produced between the end units in a direction of the connection. The end units are designed with corresponding supports for the spring units, where the supports are formed at outer casing or inside the end units. The spring unit has a casing of a netted polymer material. An independent claim is also included for a device for swiveling a component around an axis.
