Problems solved by technology

[0003] At present, oil cylinders and hydraulic cylinder earrings on the market are usually machined from steel plates or round steel. The amount of machining is large, the waste of materials is large, the production cost is high, the production time is long, and the sizes of various manufacturers are not uniform and cannot be interchanged. And it does not have the buffering and self-correcting functions of the installation angle, which will easily lead to the offset of the transmission force of the piston rod of the oil cylinder and hydraulic cylinder, resulting in early damage to the seal or deformation of the piston rod, thus making the oil cylinder and hydraulic cylinder oil leakage invalid

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , There is an ear hole in the middle of the seat body 1, the ear hole is equipped with a bearing 2, and the right side of the seat body 1 is provided with a lubricating grease nipple 5.

[0017] Such as figure 2 , There is a shoulder on the left side of the ear hole, and a circlip groove is arranged on the right side of the ear hole, a bearing 2 is arranged between the shoulder of the ear hole and the circlip groove, and a circlip 3 is housed in the circlip groove.

[0018] Such as image 3 , Figure 4 This is the structure when the bearing is converted into a bushing 4.

[0019] The specific embodiment of the present invention is:

[0020] see figure 1 figure 2 , an oil cylinder earring, including a seat body 1, a bearing 2, a circlip 3 and a lubricating oil nipple 5. There is an ear hole on the seat...

Abstract

The invention discloses an oil cylinder earring, which comprises a seat body, a bearing, a retaining ring and a lubricating oil nipple. The base body has an ear hole, one side of the ear hole has a shoulder, and the other side has a spring groove; the bearing is installed in the ear hole, and the bearing is a centripetal joint bearing. The bearing can be changed to a bushing, and the surface of the inner hole of the bushing is attached with PTFE self-lubricating material with a very low friction coefficient. The invention has high production efficiency and low production cost, has the function of angle buffer correction and self-adjustment of eccentricity, and can well solve the problem of failure of the oil cylinder due to oil leakage caused by installation deviation.

Description

technical field [0001] The invention relates to an earring used for oil cylinders and hydraulic cylinders, in particular to an earring for oil cylinders and hydraulic cylinders with the functions of angle buffer correction and self-adjusting eccentricity. [0002] Background technique [0003] At present, oil cylinders and hydraulic cylinder earrings on the market are usually machined from steel plates or round steel. The amount of machining is large, the waste of materials is high, the production cost is high, the production time is long, and the sizes of different manufacturers are not uniform, so they cannot be interchanged. And it does not have the buffering and self-correcting functions of the installation angle, which will easily lead to the offset of the transmission force of the piston rod of the oil cylinder and hydraulic cylinder, resulting in early damage to the seal or deformation of the piston rod, thus making the oil cylinder and hydraulic cylinder oil leakage ...
