    Abstract: A hydraulic hammer is disclosed that includes at least one accumulator that is connectable to a hydraulic circuit disposed in the housing of the hammer. The accumulator includes an annular base coupled to a cover with a diaphragm sandwiched therebetween. The annular base includes a proximal end and a distal end. The proximal end of the annular base defines a first central opening. The proximal end of the base in the housing define an annular inlet that encircles the first central opening and that is in communication with the first central opening. The cover also includes a proximal end and a distal end. The proximal end of the cover is coupled to the distal end of the base with the outer periphery of the diaphragm sandwiched therebetween.

    Abstract: Systems and methods can include stretching a stud of a hammer assembly by tightening, according to a preset amount, a plurality of fasteners, which can extend from a first end surface and/or a second end surface of a first nut threadedly coupled to the stud, against an upper surface of a body of the hammer assembly. The fasteners and the first nut can provide a clamping load for the stud upon completion of the tightening. The systems and methods can also include, after the stretching, tightening a second nut, which can be threadedly connected to the stud, toward a seat formed in the body of the hammer assembly; and further tightening the second nut, against the seat. The systems and methods can further include transferring the clamping load from the fasteners and first nut to the second nut.

    Abstract: An example bushing of a hydraulic hammer tool includes an outer region and an inner region. The inner region has a relatively greater hardness than the outer region. The inner region may also be compressively stressed, while the outer region may have tensile stress. The stress and/or hardness profile of the bushing may enhance its resistance to wear and galling defects when a hammer of the hydraulic hammer tool is held in alignment by the bushing. The outer region of the bushing may be relatively soft, resulting in the bushing having a relatively high level of toughness. The bushing may be formed using medium to high carbon steel by rough forming the bushing, hardening the bushing, tempering the bushing, and induction softening the outer region of the bushing.

    Abstract: A hydraulic hammer including a housing, a piston arranged for reciprocating movement within the housing, a hydraulic circuit within the housing. The hydraulic circuit is configured for connection to a source of pressurized fluid. The hydraulic circuit includes an inlet passage configured to provide a hydraulic fluid to the piston, an outlet passage configured to provide a return flow path for the hydraulic fluid from the piston a bypass passage selectively connecting the inlet passage to the outlet passage and a thermostatic valve assembly configured to connect the inlet passage to the piston when the temperature of the hydraulic fluid is below a threshold temperature and connect the inlet passage to the bypass passage when the temperature of the hydraulic fluid is above the threshold temperature.

    Abstract: A lubrication system including a drive fluid chamber and a lubricant chamber. A first movable member is movable from a first position to a second position within the drive fluid chamber in response to drive fluid pressure acting on the first movable member. A second movable member is movable between a first position and a second position within the lubricant chamber and is operatively coupled to the first movable member. A biasing member is positioned to bias the first movable member toward the first position. A relief valve is associated with the first movable member and, when the relief valve in an open state, the drive fluid pressure acting on the first movable member is reduced such that the biasing member moves the first movable member to the first position within the drive fluid chamber.

    Abstract: A system configured to couple a hydraulic hammer and tool is disclosed. A hydraulic hammer may include a housing defining a chamber, elongate along a longitudinal axis, configured to receive a tool. The chamber may comprise an opening through which the tool may be inserted. A plurality of upper splines and a plurality of lower splines may be disposed, parallel to the longitudinal axis, on an inner surface of the chamber. A locking mechanism, comprising a rotatable locking ring, may be disposed within the chamber between the plurality of upper splines and the plurality of lower splines. The locking ring may comprise a plurality of locking ring splines disposed on an inner surface of the locking ring, wherein the plurality of locking ring splines are configured to align with the plurality of upper splines and the plurality of lower splines when the locking ring is rotated to an unlocked state.
