摘要： A hand-held power tool transmission closure having a base body for closing a transmission housing opening of a transmission housing of a hand-held power tool, in particular a hammer drill or a combi-hammer, wherein the hand-held power tool transmission closure includes a tube protruding from the base body, which extends in the transmission housing when the base body closes the transmission housing opening. The hand-held power tool transmission closure includes an air channel which extends in a first air channel section through the base body and in a second air channel section through the tube so that an air mass can flow through the air channel into and out of the transmission housing.

摘要： A cutting tool mechanism 11 for providing a cutting, abrading or grinding action is disclosed. The mechanism 11 has an inner circular part 17 having teeth 19 extending radially outwardly, a surrounding circular part 25 having inner teeth 27 extending radially inwardly. The circular parts 17 and 25 co-operate by engagement their teeth 19 and 27. Rotation of one circular part causes the other to move constrained by the engagement of the teeth in an orbital, oscillatory or impact motion. An input coupling 81 is provided for transmission of rotary motion, and an output coupling 37 is provided to transmit said orbital, oscillatory or impact motion to a blade 13. In further embodiments, the surrounding circular part 25 can be provided with outwardly extending teeth and surrounded by a further outer circular part with inwardly extending teeth, to cooperate with the outwardly extending teeth, to provide more complex orbital, oscillatory or impact motion.

摘要： A buffer system for a hydraulic hammer is disclosed. The buffer system includes a wear member disposed between a first component and a second component. The wear member includes a first surface. The first surface is adapted to abut an inner surface of the first component. The wear member also includes a second surface distal to the first surface. The second surface is adapted to abut an outer surface of the second component. The buffer system also includes an insert member disposed in the wear member between the first surface and the second surface thereof. The insert member provides a visual indication when a predefined thickness of the wear member between the first surface and the second surface is worn.

摘要： The present invention relates to a hydraulic attachment comprising a hydraulic circuit, the attachment being a construction or demolition tool, in particular a hydraulic breaker, demolition shears, scrap shears, a pulverizer, a gripper, a crusher bucket or a compactor, which can be mechanically connected to a support device and hydraulically connected to the hydraulic system of the support device. In order to enable the hydraulic circuit to be opened quickly and safely within an attachment and, in particular, to make it possible to display the presence of a particular pressure level within a hydraulic attachment and to determine whether a dangerous residual pressure is present in the system, a hydraulic attachment is proposed that has a residual pressure display (40) which is connected to the hydraulic circuit of the attachment in a detachable or non-detachable manner.

摘要： The post driver with limited movement floating post anvil does not rely heavily upon the skill of the operator to efficiently drive posts. The post anvil is allowed to move up and down in relation to the driver, but its movement is limited by both lower and upper fixed barriers. Since the movement is limited, the operator can position the driver upon the post allowing the full weight of the driver framework/carrier machine to rest upon the post. The post would push the floating post anvil upward only to the point at which the upper fixed barrier prevents further upward movement of the floating post anvil. Thus, once the floating post anvil abuts the upper fixed barrier, substantially the entire weight of the post driver is resting on the post.

摘要翻译： 有限运动漂浮砧座的后驾驶员不会很大程度上依赖于操作员有效驾驶岗位的技能。 砧座被允许相对于驾驶员上下移动，但其运动受到上下固定障碍物的限制。 由于运动受到限制，操作员可以将驾驶员定位在车柱上，从而允许驾驶员框架/运载机的全部重量放置在车柱上。 该柱将浮动砧座向上推动到上部固定屏障防止浮动砧座进一步向上移动的点。 因此，一旦浮动砧座抵靠上固定屏障，基本上整个重量的后驱动器就位于柱上。

摘要： The present disclosure illustrates a compressed air tool having a silencer structure. A silencing element and an outer cover are disposed in an air exhaust channel of a main body of the compressed air tool. The silencing element has two walls and a channel. The two walls both have long slits, the long slits of the two walls are misaligned and not directly faced with each other. After the exhaust is inputted via the long slits of one of the two walls, the exhaust is flowed through the channel and emitted to the outside via the long slits of other of the two walls. Therefore, the air flow of the exhaust can be weakened, and the exhaust is then entered the countersink of the outer cover and emitted from the side hole, whereby the effect of silencing and reducing the noise caused by the emitted exhaust can be achieved.

摘要翻译： 本公开示出了具有消声器结构的压缩空气工具。 消音元件和外盖设置在压缩空气工具的主体的排气通道中。 消音元件有两个墙壁和一个通道。 两个墙壁都有长的狭缝，两个墙壁的长缝不对齐，不直接面对。 在通过两个壁中的一个的长狭缝输入排气后，排气流过通道并经由两个壁中的另一个的长狭缝发射到外部。 因此，排气的空气流可以被削弱，然后排气进入外盖的埋头孔并从侧孔发射，由此可以实现消音和减少由排气排出的噪音的影响。
