Abstract: A fluid-powered rotary actuated support for a platform, having a body with a vertical axial orientation during use. A drive member has a drive shaft extending coaxially within the body and a flange attached to an end portion of the shaft toward an upper body end. The shaft and flange are formed as an integral unit free of connection joints therebetween. The flange projects radially outward from the shaft beyond an inner body surface and is rotatable relative to the body through a horizontal plane. A first ball race is formed in the flange and a second ball race is formed in the body with balls disposed therebetween. Linear-to-rotary transmission means disposed within the body are operable for providing rotational movement between the drive member and body. The body utilizes a stationary seal to facilitate seal placement and reduce the overall length of the body. In one embodiment, the transmission means includes a plurality of rollers each having at least two roller disks adjustably axially movable relative to each other within a limited range for backlash elimination purposes. The rollers are rotatably disposed on spindles, each having a free end portion attached to an annular support plate and an opposite end portion rotatably disposed in a piston sleeve bore hole for rotational adjustment of the spindles to axially move the support plate and apply an axial force on the roller disks.

Abstract: A rotating drive mechanism for swinging doors, especially on vehicles, with a helical transmission consisting of a stator that is rigidly connected to the housing of the rotating drive mechanism, a rotor that can rotate but cannot move axially and that is rigidly connected to the driveshaft, a coupling component that moves axially to rotate the rotor in relation to the stator, and a pneumatic or hydraulic drive cylinder with a piston rod that is connected to the coupling component. The drive cylinder is an annular cylinder that has an outer and an inner jacket as well as an annular piston between the inner and the outer jacket. The coupling component is a nut that extends into the inner cylinder jacket and surrounds a rotor in the form of a threaded spindle. The rotor extends coaxially through the inside of the inner jacket and is, where it emerges from the housing, in one piece with the stub of the takeoff shaft. The coupling component is non-rotationally connected to an axial positioning mechanism that has rollers that travel in a positioning slot in the stator.

Abstract: A fluid-powered linear actuator having a body, and an output shaft with a piston portion disposed within the body. The shaft is axially movable in a first direction in response to fluid pressure on the shaft piston portion. A piston sleeve is mounted within the body and has a piston head to define with the shaft piston portion a fluid-tight chamber. A second fluid-tight chamber is provided on the opposite side of the piston head. Exterior sleeve splines transmit torque between the sleeve and the body in response to axial movement of the piston sleeve, and interior sleeve splines transmit axial force between the sleeve and the shaft in response to axial and rotational movement of the piston sleeve. In a preferred embodiment, the sleeve splines, and hence the corresponding splines on the body and shaft have the same hand with the lead of the interior splines being greater than the lead of the exterior splines so that the application of fluid pressure to the first chamber produces axial movement of the piston sleeve and the shaft in opposite directions, with the shaft moving in a first axial direction. The fluid pressure to the first chamber also applying pressure directly on the shaft piston portion to move the shaft in the first axial direction.

Abstract: Helical splined rotary actuator includes a pair of cylinder housings having inboard ends rotatably mounted in coaxial alignment on opposite ends of a center sleeve member. Contained within the housings are pistons having relatively large diameter helical spline connections with the inner diameters of the housings and smaller diameter straight spline connections with opposite ends of the sleeve member, whereby simultaneous axial movement of the pistons toward and away from each other causes relative rotation between the sleeve member and cylinder housings. The sleeve member may be connected to a first support intermediate the ends of the actuator. In like manner, the cylinder housings may be connected to a second support rotatable relative to the first support adjacent opposite ends of the sleeve member. End closures at the outboard ends of the housings have barrier sleeves extending coaxially into the outboard ends of the housings between the housings and pistons to act as barriers between the internal housing seals and external piston seals. The end closures are fixed relative to a shaft pinned to the sleeve member intermediate the ends thereof, whereby the housings are rotatable relative to the barrier sleeves but not axially movable relative thereto and the pistons are axially movable relative to the barrier sleeves but not rotatable relative thereto.
