Abstract

The lubricating device for the water pressure cylinder comprises a cylinder body, a separation ring is arranged in the middle of the cylinder body to divide the cylinder body into an upper oil storage cavity and a lower oil storage cavity, and the upper oil storage cavity is filled with an oil coating part capable of adsorbing lubricating oil; the oiling part is provided with a center hole for a piston rod of the water pressure cylinder to penetrate through and makes contact with the periphery of the piston rod through the inner wall of the center hole to be used for oiling and lubricating the piston rod, and the lower oil storage cavity is used for temporarily storing lubricating oil so as to oil and lubricate the piston of the water pressure cylinder. The lubricating device is used in the water pressure cylinder in a matched mode and can effectively lubricate the piston and the piston rod of the water pressure cylinder, the lubricating problem of the water pressure cylinder due to tap water media is solved, the running resistance of the piston and the piston rod can be effectively reduced, and abrasion of a sealing piece is relieved. The invention further provides the water pressure cylinder which is provided with the lubricating device, the running resistance of the piston and the piston rod can be effectively reduced, and abrasion of a sealing piece is relieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission devices, in particular to a lubricating device for a hydraulic cylinder and a hydraulic cylinder with the lubricating device. Background technique [0002] The hydraulic cylinder uses the pressure of water (mainly tap water) as the power source to drive the piston. It can be used in hydraulic power-assisted driving and other fields, such as the seat that assists the toilet to help the elderly to easily complete the toilet. Squat and get up movements. [0003] The hydraulic cylinder used in the traditional hydraulic system uses hydraulic oil as the working medium, and the high-pressure oil output by the hydraulic pump is used to drive the piston, and the hydraulic oil can be used to lubricate the piston. The hydraulic cylinder mainly uses tap water as the working medium. Tap water is easy to obtain, but the lubricating ability of the tap water is weak, and it has certain impurities....
