Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder assembly. Background Art

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, it can eliminate the need for a deceleration device, has no transmission gap, and moves smoothly. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] However, when the existing hydraulic cylinder is in use, when the hydraulic oil enters the hydraulic cylinder to push the piston to move, the hydraulic oil will generate a certain amount of heat energy. With the continuous and frequent use of the hydraulic cylinder, the temperature of the hydraulic oil and the hydraulic cylinder will gradually increase, and the viscosity of the hydraulic oil will decrease at high temperatures, which will in turn cause the lubricating performance of the hydraulic oil to decrease. At the same time, when the temperature of the hydraulic cylinder is high, the aging speed of the hydraulic cylinder seal will be accelerated, affecting the service life of the hydraulic cylinder; therefore, it does not meet the existing needs, and we have proposed a hydraulic cylinder assembly.
