Hydraulic cylinder structure internally provided with radial spherical plain bearing

Abstract

The invention relates to a hydraulic cylinder structure internally provided with a radial spherical plain bearing. The hydraulic cylinder structure comprises a cylinder body and a piston rod, wherein the piston rod is arranged in the cylinder body, a first oil cylinder cavity is formed between the piston rod and the cylinder body, and the cylinder body is provided with an oil port leading to the first oil cylinder cavity; and a center column is arranged in the cylinder body, the radial spherical plain bearing is arranged on the center column, a groove matched with the radial spherical plain bearing is formed in the end, close to the center column, of the piston rod, the radial spherical plain bearing is embedded into the groove, a second oil cylinder cavity is formed between the radial spherical plain bearing and the piston rod, the outer wall of the radial spherical plain bearing is attached to the inner wall of the groove of the piston rod, an oil way is arranged on the side wall of the radial spherical plain bearing and communicated with the second oil cylinder cavity and the first oil cylinder cavity, and an annular sealing part attached to the piston rod is arranged on the lateral inner wall of the cylinder body. According to the hydraulic cylinder structure, the radial spherical plain bearing is arranged between the piston rod and the cylinder body, the hydraulic cylinder structure has the advantages of being high in reliability, simple in structure and convenient to disassemble and assemble, and can favorably prolongs the service life of the piston rod.

Description

technical field [0001] The present invention relates to a hydraulic cylinder, more specifically, it relates to a hydraulic cylinder structure with a radial joint bearing inside. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or oscillating motion. Hydraulic cylinders are widely used in social production. For example, hydraulic cylinders are used in cement roller presses. The hydraulic cylinders play the role of supporting the roller presses. However, during the working process of the roller presses, the equipment as a whole is in a state of continuous shaking from side to side. , the piston rod of the hydraulic cylinder supporting the roller press is affected by continuous lateral force, and the piston rod swings left and right in the cylinder body. Using traditional support belts or copper metal supports cannot solve the problem of swinging to the piston rod b...

Hydraulic cylinders are widely used in social production. For example, hydraulic cylinders are used in cement roller presses. The hydraulic cylinders play the role of supporting the roller presses. However, during the working process of the roller presses, the equipment as a whole is in a state of continuous shaking from side to side. , the piston rod of the hydraulic cylinder supporting the roller press is affected by continuous lateral force, and the piston rod swings left and right in the cylinder body. Using traditional support belts or copper metal supports cannot solve the problem of swinging to the piston rod body and The damage caused by the seal makes the hydraulic cylinder leak and shortens the service life of the hydraulic cylinder
