摘要： A tool assembly such as a hammer assembly, includes a housing defining a chamber and a reciprocating piston arranged in the chamber for cyclical movement in a work stroke and a return stroke. The housing includes a lower housing member, an upper housing member and an engaging structure which permits the engagement of the upper housing member with the lower housing member by relative rotation of the upper and lower housing members, such that each of the lower and upper housing members defines a portion of the chamber. The upper housing member is a precision component which contains the hydraulic components or other drive components necessary to drive the piston, while the lower housing member can be manufactured separately since it does not need to be manufactured to the high tolerances required by the upper housing member. The resulting tool assembly may be more compact than a conventional tie rod tool assembly.

摘要： A tool assembly (10), for example a hydraulic or pneumatic hammer assembly, includes a housing (11) defining a chamber (16), a removable reciprocating work tool (20) arranged in the chamber, and a tool retention member (80) having an aperture through which the work tool extends. The housing (11) includes an engaging structure (50) which permits the engagement of the tool retention member (80) with the housing by relative rotation of the tool retention member and housing. The work tool (20) is provided with retention structure (44) such as a retaining flange which prevents the removal of the work tool from the housing when the tool retention member is engaged with the housing. At least some of the disclosed embodiments may eliminate the need for a retainer pin, thereby allowing the work tool to rotate, possibly avoiding wear, increasing tool life and simplifying tool replacement.

摘要： A tool assembly (10), for example a hydraulic or pneumatic hammer assembly, comprises a housing (11) defining a chamber (16), a reciprocating work tool (20) arranged in the chamber for cyclical movement in a work stroke and a return stroke, and a tool retention member (80) arranged to restrain the work tool at the end of the work stroke. The tool assembly (10) includes a shock absorber arranged to absorb impact from the work tool at the end of a stroke. The shock absorber comprises an annular resilient flange (102, 154), which may be cantilevered from the tool retention member (80) to absorb impact at the end of the work stroke or may be provided on a bushing (150) arranged to absorb impact at the end of the return stroke. The shock absorbing flange reduces the transmission of shocks into the tool assembly, thereby providing increased life for tool assembly components.
