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.

Abstract: A fluid-powered rotary actuator having a body with a cylindrical interior sidewall portion. A drive shaft extends generally coaxially within the body and is supported for rotation relative thereto. The shaft has a grooved, outwardly facing circumferential sidewall portion positioned within the body. A ring gear is positioned generally coaxially within the body and extends about the shaft with an annular space therebetween. The ring gear has a grooved, inwardly facing circumferential sidewall portion. The ring gear is formed as a separate part from the body and the ring gear grooved sidewall portion is formed prior to positioning of the ring gear in the body. The ring gear is fixedly attached to the body to prevent rotation therebetween by a weld between the ring gear and the body interior sidewall portion. A stop member is engaged by the ring gear. The stop member is axially located within the body to limit movement of the ring gear toward the body first end during assembly of the ring gear in the body. The stop member may be a stop shoulder formed integral with the body interior sidewall portion or a snap ring. In the stop shoulder embodiment, the ring gear is welded to the stop shoulder. A piston sleeve is mounted for reciprocal axial movement within the body in response to the selective application pressurized fluid thereto.

Abstract: A steering assembly for a utility vehicle having a support frame. The assembly includes a fluid-powered rotary actuator, with a body having a rotatable hollow shaft extending therewithin. An annular piston is mounted within the body about the shaft for reciprocal axial movement and rollers are provided for transmitting torque between the body and the shaft to produce rotational movement of the shaft in response to axial movement of the piston. An axially extendable member extends longitudinally within a central bore of the shaft with a lower end portion projecting out of the body and being attached to forks to which a wheel is rotatably mounted. The central bore of the shaft and the extendable member have meshing straight splines which transmit the rotational drive of the shaft to the extendable member, while allowing free axial movement of the extendable member. The extendable member has a piston portion which defines an interior fluid chamber. An accumulator is in fluid communication with the fluid chamber. The fluid chamber is filled with hydraulic oil, as is a portion of the accumulator. The remainder of the accumulator is filled with compressible nitrogen gas. The extendable member piston portion moves upwardly within the central bore in response to upper movement of the wheel to transmit the force of the upward movement through the hydraulic oil to the compressible fluid for absorption of at least a portion of the transmitted force.

Abstract: A fluid-powered, laterally tiltable quick disconnect bucket actuator. A bucket has a pair of bucket clevises, and an actuator has a generally cylindrical body with an output shaft rotatably disposed therein with an axis in general parallel alignment with a forward rotation plane through which the bucket is rotatable on a backhoe arm by the operation of a rotation link. A bracket is attached to the body and has a pair of clevises for pivotal attachment to the vehicle arm and rotation link. The output shaft has a pair of shaft attachmetn forks for each end for attaching the shaft to the corresponding bucket clevises. The one pair of shaft attachment forks is attached to and moves axially with a member which is selectively extendable relative to the shaft to move the pair of forks between a locking position holding the bucket and a release position allowing disconnection of the bucket. A linear-to-rotary transmission device disposed within the body produces rotational movement of the shaft relative to the body to produce lateral tilting of the bucket in a lateral plane generally transverse to the forward rotational plane for the bucket.

Abstract: A fluid-powered rotary actuator attachable to a boom and usable with a work implement having two hydraulic actuators. The rotary actuator has a body with a drive shaft extending longitudinally therewithin. The shaft has one end located outward of the body and fixed to an attachment flange which can be connected to a vehicle boom. An annular fluid coupling is rotatably mounted on the shaft between the flange and the body. Fluid passageways in the shaft conduct fluid to the coupling, which has three circumferential fluid distribution channels. The coupler provides the fluid to flexible hoses which extend to the hydraulic actuators. The coupling is freely rotatable relative to the shaft but has a connection finger attached thereto which is received in a hole in a connection flange which is attached to the body. The connection flange transmits a rotational force on the coupling through the finger as the body rotates to produce rotation of the coupling with the body, but the receiving hole is sufficiently larger than the finger positioned therein that axial and bending forces are not transmitted between the body and the coupling. A set of annular body and shaft inserts is positioned at each end of the body to rotatably support the body on the shaft.

Abstract: A percussion tool usable as part of a single tool impact device or a multi-tool impact device. In each case, the tool is rotatably driven by a high-torque rotary actuator with the tool being longitudinally splined and received within a correspondingly longitudinally splined hollow drive shaft of the actuator. The tool extends fully through the drive shaft to a rearward end thereof at which is positioned a percussion hammer to provide reciprocating endwise impact to the tool. The tool is held within the drive shaft by a splined lock member which can be rotated between a release position with its splines aligned with the drive shaft splines, and a locked position with its splines misaligned with the drive shaft splines. The device is mountable on a mobile vehicle having an articulated arm. The multi-tool impact devices utilizes six such units in side-by-side relation with the drive shafts of each having a gear which drivable interconnects the shafts to maintain them synchronized and couple them together for the transmission of drive force therebetween.
