Abstract
Изобретение может быть использовано в качестве исполнительного механизма в гидроприводах подъемно-транспортных машин. Цель изобретени - повышение надежности при эксплуатации. Поршневой механизм содержит цилиндр 1, рабочие полости которого св заны трубопроводами 2 через распределитель 3 с источником давлени . Шток 4 выполнен в виде замкнутого гибкого т гового органа, огибающего вне цилиндра 1 ролики 5. Поршень 6 выполнен из эластичного материала в виде тора. Торообразна оболочка снабжена размещенным в ее внутренней полости двухслойным цилиндрическим вкладышем (В), внешний слой 7 которого выполнен из упругосжимаемого материала, а внутренний слой 8 установлен с зазором относительно внутренней поверхности 9 тора и выполнен из недеформируемого материала. Поверхность В покрыта антифрикционной смазкой. 1 з.п. ф-лы, 1 ил.The invention can be used as an actuator in the hydraulic drives of hoisting-and-transport machines. The purpose of the invention is to increase reliability during operation. The piston mechanism comprises a cylinder 1, the working cavities of which are connected by pipelines 2 through a distributor 3 with a pressure source. The rod 4 is made in the form of a closed flexible traction body, enveloping rollers 5 outside the cylinder 1. The piston 6 is made of an elastic material in the form of a torus. The toroidal shell is provided with a double-layer cylindrical liner (B) placed in its inner cavity, the outer layer 7 of which is made of an elastically compressible material, and the inner layer 8 is installed with a gap relative to the inner surface 9 of the torus and is made of non-deformable material. Surface B is coated with antifriction lubricant. 1 hp f-ly, 1 ill.
