ABSTRACT:
A rotary mechanism for robot manipulators and the like has a housing and a shaft moveably disposed in the housing so that an end portion thereof is movable toward and away from the housing. A cylinder and piston assembly is connected to the shaft for moving the shaft. A robot manipulator is connected to the end portion and a mechanism for operating the manipulator is also carried there. A support is connected to the shaft and is carried therewith and is disposed at a distance from the end portion. A chain drive system is operatively associated with the shaft for rotating the shaft on the longitudinal axis thereof. A pair of braces are disposed in the housing and are engaged with the support for preventing rotation of the support during operation of the chain drive mechanism.
