摘要： Repulsive magnetic forces in the axial direction of cylinder tubes act between the rows 11 of inner magnets of pistons 10, 10 accommodated in two cylinder tubes 2, 2, and the inner magnets 12 of the pistons 10 come to a halt being slightly deviated relative to the outer magnets 22 in the axial direction of the tube. Due to this deviation, a magnetic holding force Fc is produced between the inner and outer magnets 12, 22. Since the magnetic holding force Fc is produced in a static state, a smooth movement can be attained from a static state suppressing the occurrence of a stick slip phenomenon at the start of movement as compared to the prior art, which does not produce the magnetic holding force in a static state.

摘要： A magnet type rodless cylinder provided with a slide magnetically coupled with a piston arranged in a cylinder tube and a slide able to move outside of the cylinder tube. The slide has a connection mount detachably attached to it. When attaching the connection mount, the position where the connection mount and an end cap strike/contact becomes the striking/contacting position of the piston. When using a rodless cylinder without a connection mount, the distance between the slide and an end cap when the piston is positioned at the striking/contacting position becomes longer than the striking/contacting distance due to the removal of the connection mount. Therefore, external dampers able to strike/contact the slide are detachably attached to the end caps at the slide sides. Due to this, regardless of the use or nonuse of a connection mount, the piston and slide can always stop at the striking/contacting position.

摘要： A pair of independent cylinder holes 3, 3 are formed in a cylinder tube 2 of a flat outer shape. When a pressurized fluid is alternately supplied into the cylinder tube 2 through a port 7 formed in an end cap 5, the internal pressure for operating the cylinders acts uniformly on the cylinder tube 2 greatly decreasing stress and deflection of the cylinder tube 2.

摘要： A pair of cylinder holes 10 are formed in a cylinder tube 2 in the axial direction, a slit 25 is formed between these cylinder holes, and an iron plate 22 is inserted in the slit covering the whole range of the movement of the pistons 3 in the cylinder holes. Spacers 23 made of a synthetic resin are interposed on both sides of the iron plate 22 to reliably hold the iron plate 22 in the slit 25. The iron plate 22 disposed between the cylinder holes works to decrease the repulsive force acting between the inner magnets 14 of the pistons and produce an attracting force between the iron plate 22 and the inner magnets 14, and a contact surface pressure between the wear rings 9 of the pistons 3 and the wall surfaces of the cylinder holes 10 can be adjusted to a suitable value.

摘要翻译： 一种磁体型无杆气缸，其具有与布置在气缸管中的活塞磁耦合的滑块和能够移动到气缸管外部的滑块。 滑块具有可拆卸地连接到其上的连接支架。 当安装连接支架时，连接支架和端盖撞击/接触的位置变为活塞的撞击/接触位置。 当使用没有连接支架的无杆气缸时，当活塞定位在撞击/接触位置时，滑块和端盖之间的距离比由于拆卸连接支架的撞击/接触距离变得更长。 因此，能够滑动/接触滑动件的外部阻尼器可滑动地附接到端盖。 因此，无论使用或不使用连接支架，活塞和滑块都可以始终在撞击/接触位置停止。

摘要： The elastomer dampers are disposed at both ends of the actuator cylinder in order to stop the piston moving in the cylinder at its stroke ends. The elastomer damper includes a pair of the protruding portions which abut the piston at its stroke end. The protruding portion has an tapered shape in which the cross sectional area thereof gradually decreases from the base to the top. Therefore, when the piston abuts the protruding portions and compresses the protruding portions, the braking force exerting on the piston gradually increases without sudden change. Therefore, the piston decelerates smoothly at its stroke ends. Further, since the top surface of the protruding portion is formed as a flat plane and the top surface is connected to the tapered side surface of the protruding portion by a round surface, no stress concentration occurs at this portion. Therefore, cracks or breakage of the material do not occur in the top surface even after a long operating time of the actuating cylinder.
摘要翻译： 弹性体阻尼器设置在致动器气缸的两端，以便使活塞在其行程末端处在气缸中移动。 弹性体阻尼器包括在其行程末端处邻接活塞的一对突出部分。 突出部具有从基部到顶部的横截面积逐渐减小的锥形形状。 因此，当活塞抵靠突出部分并压缩突出部分时，施加在活塞上的制动力逐渐增加而不会突然改变。 因此，活塞在行程末端平稳地减速。 此外，由于突出部的上表面形成为平面，并且顶面通过圆形表面连接到突出部的锥形侧表面，因此在该部分处不发生应力集中。 因此，即使在致动缸的长时间操作之后，也不会在顶表面上出现裂纹或断裂。
