An industrial delta robot with an arm system rotatable in space and including a base section, a moveable plate, several multi-jointed pull rods and a telescopic axle arranged between the base section and the moveable plate, opposite ends of the pull rods and of the telescopic axle being connected with the base section and the moveable plate respectively, and the telescopic axle comprising an inner axle and an outer tube arranged on the inner axle and displaceable in a longitudinal direction where a pair of end-to-end torsional rigid bushings are arranged in a stationary manner on the outer tube in which the inner axle is mounted to be displaceable, the bushings being spaced apart at confronting inner ends to form a transversely extending lubrication pocket for continuous lubrication of the inner axle during movement relative to the bushings.

Industrial robot

A manipulator for an environment with hygienic requirements, comprising a stationary element ( ) with a plurality of drive means ( ), and arms ( ) attached to the drive means, which arms, via a respective linkage ( ), support a movable element ( ). The drive means ( ) are enclosed in an enclosure ( ) which encloses a gaseous coolant which, by a forced flow, takes up heat from the motors of the drive means.

Manipulator

A manipulator comprising a linkage with at least two links ( ) which have ball joints ( ) at their ends, and a spring device ( ) which exerts a tensile force between the links. The spring device ( ) comprises a first drawing device ( ) with a first angle device ( ), a second drawing device ( ) with a second angle device ( ), which are arranged, displaceable in parallel, side-by-side, and a spring member ( ) arranged between the angle devices. The tensile force arises by the spring member exerting a compressive force against the angle devices.
