摘要： An impact rotary tool includes a hammer, an anvil, an output shaft, a housing, and a bearing (first bearing). The bearing (first bearing) is held by the housing. The anvil includes a first contact portion. The output shaft includes a second contact portion. The second contact portion receives, from the first contact portion, force that causes the output shaft to rotate. The bearing (first bearing) is in contact with at least one of the first contact portion or the second contact portion and supports at least one of the output shaft or the anvil rotatably.

摘要： A hydraulic, pneumatic, or electric tool may include a spindle that is adapted for rotational movement. A swing arm may be coupled to the spindle such that the rotational motion of the spindle is transferred to the swing arm. The swing arm may make contact with an anvil such that the rotational motion of the swing arm causes the anvil to move along a linear path. A piston may be operatively coupled to the anvil to follow the linear movement of the anvil. The piston may be adapted to interact with an energy storage medium when the swing arm moves the anvil in the first direction, causing energy to be stored. As the swing arm continues to rotate, the swing arm may lose contact with the anvil, thus allowing the energy storage medium to urge the piston and the anvil in a second direction opposite the first direction.

摘要： The invention relates to a method for fitting a breaking device tool with a bearing, a breaking device and a tool bushing. The tool of the breaking device is fitted with a bearing with at least one bearing bushing manufactured of bearing material and arranged in a bearing space. There is a clearance fit between the bearing bushing and the bearing space, whereby the bearing bushing is insertable into the bearing space by manual force. During the use, compression stress pulses are given to the tool with a percussion device, whereby stress waves travel in the tool, which waves generate on the tool surface a movement in the direction of its perpendicular. This movement is transmitted to the bearing bushing, and it deforms the bearing bushing in the radial direction in such a way that the bearing bushing is pressed against the bearing space.
摘要翻译：本发明涉及一种用于将断裂装置工具与轴承，断开装置和工具套管相配合的方法。破碎装置的工具装配有具有由轴承材料制成并且布置在轴承空间中的至少一个轴承衬套的轴承。在轴承衬套和轴承空间之间存在间隙配合，由此通过手动力将轴承衬套插入到轴承空间中。在使用过程中，使用冲击装置向工具施加压缩应力脉冲，由此应力波在工具中行进，该波在工具表面上在其垂直方向上产生运动。该运动被传递到轴承衬套，并且使轴承衬套在径向上变形，使得轴承衬套压靠在轴承空间上。

摘要： It is, accordingly, an object of the present invention to provide an electric hammer with improved construction, while ensuring the vibration reduction performance. According to the present invention, a representative electric hammer may include a hammer bit, a driving motor, a crank mechanism and a counter weight. The crank mechanism drives a striker by converting a rotating output of the driving motor to linear motion in the axial direction of the hammer bit. The counter weight is detachably mounted to the crank mechanism and serves to reduce vibration of the striker. According to the representative hammer, because the counter weight is detachably mounted to the crank mechanism, it is possible to switch between the mode in which the counter weight is mounted on the hammer body in order to reduce and alleviate vibration and the mode in which the counter weight is removed from the hammer so that the operation can be performed with the hammer having a lighter weight and slimmer appearance. Thus, utility of the electric hammer can be improved.
摘要翻译：因此，本发明的目的是提供一种具有改进结构的电锤，同时确保减振性能。根据本发明，代表性的电锤可以包括锤钻头，驱动马达，曲柄机构和配重。曲柄机构通过将驱动电动机的旋转输出转换成锤头的轴向的线性运动来驱动撞针。配重可拆卸地安装在曲柄机构上，用于减轻撞针的振动。根据代表性的锤子，由于平衡重可拆卸地安装在曲柄机构上，因此为了减轻和减轻振动，可以在安装在锤体上的配重的模式之间进行切换，从锤子中取出配重，使锤子的重量更轻，外观更细，可进行操作。因此，可以提高电锤的效用。

摘要： An electric hammer includes a housing, an electric motor, an output assembly, an impact assembly, a mounting shaft, a clutch assembly, and a switching assembly. The mounting shaft is rotatable about a second axis. When the electric hammer is in the drill mode, a sleeve of the output assembly rotates. When the electric hammer is in the hammer drill mode, the sleeve rotates and an impact block of the impact assembly reciprocates in the sleeve. The switching assembly is configured to switch the clutch assembly between a first state and a second state and includes a switching element. The switching element includes a forced end and a drive end, the output assembly moving along a first axis drives the forced end to move, and the drive end is configured to drive the clutch assembly to be switched to the first state.
