Abstract:
In a fluid power gripper comprising a housing having a receiving space having a longitudinal axis in which two pistons are located and able to be moved by fluid power to perform oppositely directed axial drive movements, each of the two pistons being connectable with a gripper element and a synchronization means, the synchronization means including a body of revolution, for synchronization of the drive movements of the two pistons, and having first mesh means, provided on the two pistons, and second mesh means simultaneously in engagement with the first mesh means, the second mesh means being provided on the body of revolution, and axial tails provided on the two adjacent end regions of the two pistons, the axial tails overlapping one another axially and being opposite to each other with an intermediate space defined therebetween, the tails furthermore including, on facing lateral surfaces thereof, the first mesh means, the body of revolution including the second mesh means being arranged in the intermediate space present between the two axial tails and being mounted for rotation about an axis of rotation extending perpendicular to the longitudinal axis of the receiving space in relation to the housing, the improvement comprising the housing being provided with at least one axially extending longitudinal slot open both radially inward into the receiving space and radially outward to an outer face of the housing, the at least one longitudinal slot including an entraining means extending therethrough, the entraining means producing an entraining connection between a respectively associated piston and a respectively associated gripper element arranged to slide on an outer region of the housing, the entraining means extending outwardly from the housing at a right angle to the axis of rotation of the body of revolution and crosswise to the longitudinal axis of the receiving space.
