Abstract: A fluid-powered rotary actuator for providing rotary movement between first and second external members. The actuator includes a cylindrical body with first and second ends. The body is adapted for coupling to the first external member, and a shaft extending generally coaxially within the body and supported for rotation relative thereto. The shaft having an adjustable end limit of rotation relative to the body. The shaft has an end portion adapted for coupling to the second external member to provide rotational movement between the first and second external members. An annular body insert is positioned coaxial with the body and at least partially within the body at the body first end. The body insert is formed as a separate part from the body and is adjustably rotatable relative to the body to permit adjustment of the end limit of rotation of the shaft relative to the body. The body insert is restrained by the body against axial movement relative to the body during powered operation of the actuator. An end cap is securely attached to the body at the body first end and spaced axially outward of and away from the body insert to define a compartment therebetween. An adjustment member extends through an aperture in the end cap with an interior portion within the end cap compartment in position to engage the body insert and an exterior portion accessible from the exterior of the end cap compartment. The adjustable member is adjustably movable in the aperture to apply an adjustment force on the body insert to adjustably rotate the body insert relative to the body to a selected rotational position relative to the body in order to adjust the end limit of rotation of the shaft relative to the body. The adjustment member, when not being adjustably moved in the aperture, holds the body insert to prevent its rotation from the selected rotational position relative to the body. A piston is mounted within the body and is reciprocally axially movable therein in response to selective application of pressurized fluid thereto. A torque-transmitting annular member is positioned generally coaxially within the body for movement with the piston.

Abstract: A fluid-powered actuator having a body with a shaft adapted for coupling to an external device to provide rotational drive thereto. A piston sleeve is mounted for reciprocal longitudinal movement within the body to provide rotational drive to the shaft. A plurality of seals are positioned within the body to provide a fluid-tight seal between the body and the shaft, and between the piston and both the shaft and the body. A pair of support members are positioned out of the body and fixedly attached to the body at spaced-apart locations. Each support member has an attachment portion extending circumferentially fully about the body, and a mounting portion. A pair of boom attachment plates are weldable to the mounting portions while the shaft, piston, torque-transmitting member, and seals remain assembled within the body. To avoid damage to the seals, a fluid channel is formed at least partially within each of the attachment portions and fully encircles the body. Cooling water is passed through the channel to absorb and transport away from the body a sufficient portion of the heat applied during welding of the attachment plates to prevent the heat from damaging the seals. Each of the channels is provided with a water inlet and a discharge outlet. In an alternative embodiment, the support member extends longitudinally along the body and defines a longitudinally extending fluid channel positioned between the support member and the body.

Abstract: An air-powered actuator having a body with first and second ends, an axially transverse annular bulkhead positioned therebetween, and an output shaft with a splined exterior portion. The body includes first and second end walls with each end wall having a sleeve mounted coaxially within the body about the shaft and projecting axially inward within the body. A piston sleeve is disposed for axial reciprocating movement within the body. The piston sleeve has a pair of piston heads, an outer sleeve, and an inner sleeve. The outer sleeve is mounted coaxially within the body inward of the bulkhead and about the first and second sleeves to define therewith a fluid-tight outer chamber containing the piston heads, each positioned to an opposite side of the bulkhead to define four fluid-tight chambers and to which pressurized air is applied. Also defined is a fluid-tight inner chamber containing lubricating oil. The outer sleeve is attached to the piston heads for reciprocating travel therewith. The inner sleeve is mounted coaxially within the inner chamber, inward of the second sleeve and about the shaft. The inner sleeve is attached to the outer sleeve for reciprocating travel therewith. The inner sleeve has a splined exterior portion meshing with the second sleeve splined interior portion and a splined interior portion meshing with the shaft splined exterior portion to translate axial movement of the piston sleeve into relative rotational movement between the shaft and the body.
