Abstract
A gripper mechanism for machines, robots and manipulation devices, comprising at least one moving gripping finger, driven by a driveshaft of multiple parts, a crank, belt or gear shaft, wherein the centering of the parts relative to each other and the transmission of the torque from a driving part to the next part, up to the gripping finger, is achieved by means of axial toothing, preferably a pinion gearing with pins and drillings. The driveshaft is preferably provided with a carrying support bearing. As a result of the splitting of the driveshaft, it is possible to cast the housing in one piece with two cavities for housing the operating unit and the transmission. The gripping finger or the lever driving the gripping finger are externally fixed to the driveshaft in an axial manner.
