摘要： A vibration reduction apparatus (501) for use with a hammer tool having a hammer piston (520) is shown. The hammer piston (520) is caused to reciprocate in cylinder (530) by rotation of a gear wheel (523) about axis (524), the hammer piston (520) being mounted to the gear wheel (523) via piston arm (531) and pivot pin (522). Reciprocating motion of the hammer piston causes a flying mass (569) to be driven along cylinder (530) to impart a hammer action to a bit of the tool. The gear wheel (523) is caused to rotate about axis (524) by meshing of gear (514) on drive shaft (511) with gear teeth (532) on the periphery of gear wheel (524), the drive shaft (511) being caused to rotate by a motor (not shown) of the tool. a cam (533) is rigidly mounted around gear wheel (523), a counterweight 5219 surrounds piston cylinder (530), and a cam follower (534) is provided on counterweight 521. The cam follower 534 on counterweight 521 is urged into contact with cam (533) by means of a compression spring (535). The external profile of the cam (533) is such that rotation of gear wheel (534) to cause reciprocating motion of hammer piston (520) causes oscillation of counterweight (521) relative to piston cylinder (530) in antiphase to motion of the hammer piston (520) to counteract vibrations produced by operation of the hammer action of the tool

摘要： A drilling and/or hammering tool which includes a hollow spindle (1) and a tool holder (10) that can be attached to an end (18) of the spindle and removed therefrom. The toll holder comprises a tool holder body (14) which can be fitted within the end of the spindle and releaseably locked therein by means of at least one locking element (32) and a locking ring (42) for releasably holding the or each locking element in a locked position in which the locking element(s) lock(s) the tool holder to the spindle. The tool holder (10) comprises a manually actuable sleeve (40) for rotating the locking ring (42) in a first direction and for rotating the tool holder body (14) in a second opposite direction, and resilient means (62) for urging the tool holder body to follow the movement of the locking ring in the first direction and the locking ring to follow the movement of the tool holder body in the second direction. The resilient means urges the locking ring and the tool holder body into relative rotational positions in which the locking ring (42) holds the or each locking element in the locked position. The locking ring (42) has an internal radius that varies along its circumference so that rotation of the locking ring about the axis of the tool holder body will move it between a locking position in which it causes the or each locking element (32) to retain the toll holder body in the spindle, and a release position in which it will allow the or each locking element to move radially to release the tool holder body.

摘要： A hand held motor driven electrically powered hammer, comprising an air cushion hammering mechanism in which an air cushion (44) is formed between a piston (38) and a ram (58) and a crank drive arrangement for converting a rotary drive from the motor (2) to a reciprocating drive to the piston (38). An intermediate gear arrangement (14) is provided between the motor (2) and the crank drive arrangement for transmitting rotary drive between the motor and the crank drive arrangement. The crank drive arrangement comprises a con-rod (34), which is made of a plastics material and is designed to break when the air cushion (44) between the piston and the ram deteriorates. In this way the hammer fails by the relatively weak con-rod (34) failing when the air cushion deteriorates due to deterioration of the seals between the piston and the hollow spindle and the ram and the hollow spindle. The failed hammer can be serviced by replacing the con-rod and seals, thereby delaying irreparable failure of the hammer due to repeated impacts between the piston and ram.
摘要翻译：一种手持马达驱动的电动锤，包括气垫锤击机构，其中气垫（44）形成在活塞（38）和冲头（58）之间，曲柄驱动装置用于将来自马达的旋转驱动器（2）到往活塞（38）的往复运动。在马达（2）和曲柄驱动装置之间设置有中间齿轮装置（14），用于在马达和曲柄驱动装置之间传递旋转驱动。曲柄驱动装置包括由塑料材料制成的连杆（34），并被设计成当活塞和柱塞之间的气垫（44）劣化时断裂。以这种方式，由于活塞和中空主轴以及冲头和中空心轴之间的密封件的劣化，当气垫劣化时，相对较弱的连杆（34）不能发生锤击。可以通过更换连杆和密封件来维修故障的锤子，从而延迟由于活塞和压头之间的反复冲击造成的锤子的不可修复的故障。

摘要： A tool holder (2) for a powered hammer comprising a tube-like tool holder body (66) which has a forward end for non-rotatably receiving a hexagonally cross-sectioned shank (3) of a hex-shanked tool. The forward ha an axially extending slot (10). A locking body (54) extends through the slot and is moveable between a radially inward locked position in which it engages an axial closed groove (88) in the tool and a radially outward release position. A locking member (52) and associated sleeve (50) are manually axially slidable to move locking body (54) between the locked and release positions. Should the tool be inserted in an incorrect orientation, the locking body (54) is trapped by the shank (3) of the tool in its release to its locked position. This provides a clear visual indication that the tool has been inserted incorrectly.

摘要： A hand held motor driven electrically powered tool, in particular a rotary hammer, comprising a spindle (40) for rotatingly driving a tool or bit (68), a spindle rotary drive train (14, 5, 10) for rotatingly driving the spindle (40) and an arrangement for detecting blocking events (16, 17). Blocking events occur when the tool or bit of the tool become rotationally fixed in the material being bored in which case the rotary drive on the spindle from the motor causes the tool housing to rotate in a, user's grip. According to a first aspect of the invention an overload clutch (14) is provided in the spindle rotary drive train for transmitting rotary drive to the spindle below a predetermined torque and slipping above the predetermined torque arranged such that the overload clutch cuts off rotary drive to the spindle, for example by reducing the predetermined torque at which the overload clutch (14) slips when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected. According to a second aspect of the invention there is provided a mode change mechanism (45, 47, 49, 43) for selectively disengaging a clutch (10, 7) so as to cut off the rotary drive to the spindle (40) and the clutch is disengaged when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected.
