摘要： An axial bearing includes a first piston and a second piston. Axial contact surfaces between the pistons are arranged in the same pressure space. The same pressure fluid fed to the axial bearing acts on the contact surfaces and on working pressure surfaces of the pistons. A rock drilling machine is also provided with such an axial bearing.

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： A rotary hammer includes a motor with an output shaft and pinion. The pinion drives a gear which is mounted to a drive shaft. A crank plate having an eccentrically disposed crank pin is mounted to the top of the drive shaft. A crank arm is pivotally connected to the crank pin and to the underside of a hollow piston. Hollow piston defines an internal bore, and the hollow piston is slidably mounted on two guide rods. Rotation of the drive shaft and turns the crank plate, and the eccentric motion of crank pin drives the crank arm. Due to the pivotal connection between the crank arm and the hollow piston 44, the hollow piston is caused to reciprocate back and forth along the guide rods.

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： A handheld power tool is disclosed. The tool has a housing, a hammer mechanism and a torque coupling. The hammer mechanism includes a beater which is movably guided along the working axis in the guide tube. The guide tube is mounted in a suspension attached to the housing so that it is movable along the working axis. The torque coupling is mounted on the guide tube and is supported on the suspension in the impact direction. The guide tube is supported on the torque coupling in the impact direction. The guide tube may be shifted with respect to the housing in the impact direction such that the torque coupling is shifted relative to the housing through the guide tube in a positively guided manner.

摘要： A power tool comprises a housing having at least two housing parts and at least one recess, a portion of the recess provided by each housing part, and a bearing located in the recess. The power tool includes a seal comprising an elongate seal member located between the housing parts to seal at least a portion of the housing. The seal includes at least one polymeric extension part extending from the elongate seal member and in contact with an external part of the bearing without extending around the bearing. The polymeric extension part of the seal prevents the external part of the bearing from rotating with respect to the housing during use of the power tool.
