Abstract

Изобретение относитс к машиностроению , в частности к объемному гидроприводу , и может быть использовано в гидроцилиндрах с гибкими механизмами дл преобразовани поступательного движени поршн , в том числе в станках, роботах и автооператорах. Цель изобретени повышение нагрузочной способности цилиндра . В гильзе 1 силового цилиндра размещен поршень 5, скольз щий по штоку 4, установленному в крышках 2 и 3 с возможностью вращени . Со штоком 4 жестко св заны диски б и 7, снабженные упорами, взаимодействующими с последовательно установленными шариками 16, упирающимис с двух сторон в поршень 5. Направл ющими дл шариков 16 служит шток 4, по крайней мере два цилиндрических валика и криволинейные каналы, образованные канавками в крышках 2 и 3 и дисками 6 и 7. Шарики 16. работа на сжатие, передают усилие от поршн 5 через упоры на диски 6 и 7, преобразу при этом поступательное движение поршн 5 во вращательное движение штока 4. 2 з.п.ф-лы, 3 ил.The invention relates to mechanical engineering, in particular to a volumetric hydraulic actuator, and can be used in hydraulic cylinders with flexible mechanisms for converting the translational motion of the piston, including in machine tools, robots and auto operators. The purpose of the invention is to increase the load capacity of the cylinder. In the liner 1 of the power cylinder, the piston 5 is disposed, sliding along the rod 4, mounted in the covers 2 and 3 for rotation. Disks B and 7 are rigidly connected to rod 4 and provided with stops interacting with successively mounted balls 16 that abut on both sides against piston 5. Rods 4, at least two cylindrical rollers and curved channels formed by grooves serve as guides for balls 16 in covers 2 and 3 and discs 6 and 7. Balls 16. compression work, transmit force from piston 5 through stops to disks 6 and 7, while converting the translational movement of piston 5 into rotational movement of rod 4. 2 Cpf lts, 3 ill.

Claims

15 claims

1. A power cylinder containing a sleeve with covers, a rod on which two disks are rigidly mounted, a piston mounted in the sleeve with the possibility of moving

20 relative to the rod and with the formation of working cavities, each of which contains a flexible transmission mechanism, one end connected with a piston, and the other with a disk, characterized in that. in order to increase the loading capacity of the cylinder, the flexible transmission mechanism is made in the form of balls provided with appropriate guides, the diameter of the balls being less than the diameter of the piston.

2. The cylinder according to claim 1, with the fact that the guides are made in the form of curved channels in the covers and at least two cylindrical rollers whose axes are parallel to the axis of the rods, and the rollers are rigidly fixed in caps and placed in the sealed bore of the piston, and the disks are equipped with stops interacting with the balls.

40 3. The cylinder according to claims 1 and 2, on the basis of the fact that the curved channels in the covers are limited by disks.
