Abstract
A wrist unit for an industrial robot comprises a wrist housing detachably mounted to a distal end of a robot arm, the wrist housing containing rotatably mounted first and second, parallel, secondary drive shafts on the input ends of which are mounted cylindrical driven gears for engagement with the respective cylindrical drive gears located on primary drive shafts on the robot arm. The driven gears and the drive gears are so disposed that an imaginary line extending through the centers of the gears are offset from the center axis of the coaxial drive gears, the wrist housing being radially adjustable on the end of the robot arm for adjusting the gear clearance between the drive gears and the driven gears.
