Abstract

The invention discloses a sealing combined type oil cylinder device. specially, a first sealing part and a second sealing part are installed on a piston rod, an oil drain hole is formed in the outer side of the second sealing part, the first sealing part and the second sealing part are the same in structure, the first sealing part and the second sealing part are both composed of bushes, sealing rings and sealing grooves. The sealing combined type oil cylinder device is excellent in sealing performance and solves the problem of oil leakage of an oil cylinder.

Description

technical field [0001] The invention relates to an oil cylinder device, in particular to an oil cylinder device with a combined seal. Background technique [0002] Hydraulic pressure is widely used in industrial and civil industries due to its large transmission force, easy transmission and configuration. Compared with mechanical rotation and electric transmission, hydraulic transmission has the following advantages: various components of hydraulic transmission can be conveniently and flexibly arranged according to needs; light weight, small size, small motion inertia, fast response speed; convenient manipulation and control, A wide range of stepless speed regulation can be realized; overload protection can be realized automatically. [0003] The hydraulic cylinder device generally uses mineral oil as the working medium, the relative moving surface can be self-lubricated, the service life is long, and it is easy to realize linear motion and machine automation. When the ele...
