Description
Technical field
The utility model relates to technical field of hydraulic pressure, more particularly, relates to a kind of numerical control oil cylinder.
Background technique
Oil cylinder and oil hydraulic cylinder, oil hydraulic cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional.Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion (or oscillating motion) by oil hydraulic cylinder.Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.The pressure reduction on oil hydraulic cylinder ouput force and piston effective area and both sides thereof is directly proportional; Oil hydraulic cylinder is made up of cylinder barrel and cylinder cap, piston and piston rod, seal arrangement, damping device and venting gas appliance substantially.
