Abstract: A gripper device (10) is provided for mounting rubber elastic rings (5) on the inner wall (62) of a workpiece opening and/or on the exterior of a workpiece. The device includes a basic housing (12), forming jaws (14) that are displaced in relation to the basic housing (12) and bearing jaws (16). To displace the plate element together with the jaws that are located on the element in an axial direction, the element is provided with a piston (20) which engages in a piston cylinder (22) in the basic housing. The displacement of the jaws that are located on the plate element (18) is mechanically coupled by a common actuator (24) and the actuator (24) is driven by an actuator piston (25) that is located in the piston (20).

Abstract: The invention relates to a gear mechanism (40), in particular a linkage mechanism, having a base unit (42) and a rotational unit (44) which is mounted such that it can be rotated relative to the base unit about an articulation axis (46; 18), wherein the base unit has a drive element (48; 10) which can be driven rotationally, in particular, perpendicularly with respect to the articulation axis, having two rotationally mounted rotary members (54, 56; 14, 16) which can be driven in opposite directions by the drive element and are arranged, in particular, coaxially with respect to one another, wherein each of the rotary members drives a coupling element (60, 62; 30, 32) which is operatively connected to it when the drive element is rotating, wherein the two coupling elements are arranged such that they are mounted rotatably in a cage (68) of the rotational unit and are operatively connected to one another in such a way that, and wherein the drive body is operatively connected to the rotary members, the rotary mem
