Abstract
A gripper mechanism for machines, robots and manipulation devices comprises at least one moving gripping finger, operated by coupling to an operating mechanism by two drive shafts. As a result of operating the gripping finger by two connecting bars, in turn each driven by the drive shafts, it is possible to move the gripping finger through a rotation over 180° through the path or range thereof and hence securely transmit forces and torques without tipping or getting in an unstable position. The drive shafts are divided axially into at least two parts in order to be housed completely in an enclosed and unitary gripper housing, protected from dust and dirt and hermetically sealed. The different parts of the drive shafts are centered on one another and positively connected by means of axial toothing, in the form of pinion gears and pins, and have a carrier support bearing.
