    专利说明:

    The invention relates to hydraulic drives, in particular rodless power cylinders, in which the transfer of force is carried out by means of steel bands. The well-known tape cylinder, which encloses the body, the piston actuated by the liquid, and the rod is made of flexible steel tape, running along guide rollers mounted at the ends of the body, the force removal unit with sliders is placed outside the body, and the ends of the tape are fixed in the sliders, and the piston tape system - the force removal unit - the tape piston is made with a prestressing voltage. The disadvantages of the known cylinder are the difficulty of exact installation of the tape, failures caused by running off of the tape from the guide rollers. due to saber shape, especially when the rollers are far away from each other. The aim of the invention is the elimination of the tape production due to manufacturing, the provision of prestressing on the unloaded side of the tape and its exact installation, and the elimination of run-off of the guide rollers. This goal is achieved by the fact that in a belt cylinder containing a body, a liquid-actuated piston with a rod made of flexible steel tape, passing along guide rollers mounted at the ends of the body, the force removal unit with sliders placed outside the body, the ends of the tape are fixed in sliders, and the system piston - tape - force removal unit - tape - piston is made with prestressing, the sliders are provided with stops, and the ends of the tape are fixed in the sliders hingedly, while between the sliders and at least one przgzhina, whose margin is 3-25% of the maximum driving force of the piston, and the maximum prestressing force of the belt is 50 maximum driving force, in addition, the width of the belt is 1 / 3-2 / 3 of the inner diameter of the cylinder FIG. 1 shows the ribbon cylinder, general view; in fig. 2 removal unit; FIG. 3 shows the force removal unit (top view in FIG. 1); in fig. 4 — force removal unit (embodiment without spring); in fig. 5.- diagram test tape. The tape cylinder comprises a housing 1 in which a piston 2 is placed. On the heads 3 and 4 of the housing 1, there are guide rollers 5 and 6, along which the steel belt 7 slides connected to the piston 2 and the force pick-up unit 8 moving along the housing 1, the ends of the tape are provided with tips 9 and 10. The tips 9 and 10 are fixed in sliders 11 and 12, separated by a protrusion-gripper 13 with a threaded rod 14 and adjustable stops 15 and 16. The sliders 11 and 12 are strutted by means of springs 17 and 18, and the spring 17 is connected to the pin 19 of the slide 11 and to the pin 20 of the slide 12, and the springs 18 - with a trunnion 21 of the slider 11 and with a trunnion 22 of the slider 12. The prestressing of the belt 7 is created by moving the adjustable stops 15 and 16. In the embodiment of the force removing unit 8 without springs (Fig. 4), the preload of the belt 7 is determined by the position stops 15 and 16 relative to the strips 23 and 24, rigidly mounted in the node 8 removal effort. Belt cylinder works as follows. When supplying the working medium under pressure to one of the cavities of the housing 1 formed by the piston 2, the latter begins to move, moving the force removal unit 8. In this case, the prestressing of the belt 7 should amount to 50% of the maximum possible force of the piston 2 in the embodiment of FIG. 4 or 25% design according to FIG. 2, 3, which guarantees the lack of saber-like tape 7, exact coincidence with the suspensions of the force removal unit, precise guidance on the guide rollers and increases the reliability of the cylinder.
