摘要： The invention relates to a device for connecting a pneumatically or hydraulically operated tool to a connection coupling in order to provide the connection to a transport line which guides a liquid or gaseous medium. The invention is characterised by a first part (11) with an engaging section (13) which is provided so that it can be inserted into a receiving element on the connection coupling and therefore be detachably connected with the same. The device also has a second part (3) with a connecting section (5), which is configured for being permanently connected to the tool. The two parts (3, 11) each have at least one additional section (9, 17), one of said additional sections (9) radially, externally surrounding the other, at a distance, and an elastic connection (19) being provided between the two additional sections. Said connection can be produced by casting, injecting or extruding an elastic, rubber-type material between the two sections.

摘要： A pneumatic percussion power tool has a percussion tool housing (1), in which a drive piston (2) and a percussion piston (9) are movable in axial direction. The motion of the drive piston (2) generated by a crank mechanism is transmitted to the percussion piston (9) through a pneumatic spring in a first chamber (10), said piston cyclically striking a ram (11) or a tool. The backward motion of the percussion piston (9) rebounding from the ram (11) is supported by increasing air pressure in a third chamber (15) that is supplied with air by the drive piston (2) through a second chamber (14) and a communicating channel (13).

摘要： The invention relates to a drive piston for a pneumatic impact mechanism used in a hammer drill or paving breaker. Said drive piston is comprised of at least two parts made of different materials having different densities. It is thus advantageous if the drive piston comprises a steel sleeve (1) whereas a piston base (4) and a piston suspension (5) are made of a plastic material. A steel which corresponds to the surrounding sliding partners is provided in the areas of the drive piston which are thermally stressed and which are subject to wear, whereas plastic is used for decreasing the total weight of the drive piston and also for reducing the vibrations in other parts.

摘要： An impacting mechanism (10) for impacting a surface (78). An impacting mechanism having plungers spaced apart and adjacent allows fractured pieces to fly away and has a latch assembly that puts side loads on the plungers. An impacting mechanism (10) having an impact plunger (16) disposed in generally centered relation within a tubular actuator (14) shields the impact to contain fractured pieces and provides a plurality of latch assemblies (99) to equalize loading. The impacting mechanism (10) breaks composite material into a plurality of pieces.

摘要： Systems and methods can include applying, using a nut assembly (70) including a first nut (72) and a plurality of fasteners (80) provided in respective threaded holes (78) of the first nut (72), a first tensioning force for a stud (50) of a hammer assembly (30). The systems and methods can also include applying, using the nut assembly (70), a second tensioning force for the stud (50) of the hammer assembly (30). The first tensioning force can be applied with the first nut (72) in a first orientation whereby a first end surface (73) of the first nut (72) faces a first direction and a second end surface (74) of the first nut (72) faces a second direction opposite the first direction. The second tensioning force can be applied with the first nut (72) in a second orientation whereby the first end surface (73) of the first nut (72) faces the second direction and the second end surface (74) of the first nut (72) faces the first direction. The second tensioning force can be greater than the first tensioning force.

摘要： Systems and methods can include stretching a stud (50) of a hammer assembly (30) by tightening, according to a preset amount, a plurality of fasteners (80), which can extend from a first end surface (73) and/or a second end surface (74) of a first nut (72) threadedly coupled to the stud (50), against an upper surface (39) of a body (33) of the hammer assembly (30). The fasteners (80) and the first nut (72) can provide a clamping load for the stud (50) upon completion of the tightening. The systems and methods can also include, after the stretching, tightening a second nut (60), which can be threadedly connected to the stud (50), toward a seat (37) formed in the body (33) of the hammer assembly (30); and further tightening the second nut (60), against the seat (37). The systems and methods can further include transferring the clamping load from the fasteners (80) and first nut (72) to the second nut (60).
