Abstract

The utility model discloses a liner tube subassembly, including the liner tube body, the liner tube body includes the annular base of circle, is equipped with the inner cover body on the base, still is equipped with outer cover on the base, forms the holding chamber between outer cover body and the inner cover body, is equipped with the perforation that the symmetry set up on the inner cover body, is equipped with the ball in the holding intracavity, and this ball is global to pass during the perforation stretches into the hole of the inner cover body, and it has the emollient with the ball contact to fill in the holding intracavity, and this emollient is molybdenum disulfide solid lubricant. This effectively improves the lubrication performance.

Description

Liner tube assembly

Technical Field

The utility model relates to a mechanical parts, concretely relates to bushing pipe subassembly.

Background

In the moving part, because the abrasion of parts is caused by long-term friction, the parts must be replaced when the clearance between the shaft and the hole is abraded to a certain degree, so a designer selects a material with lower hardness and better wear resistance as the liner tube in the design, the abrasion of the shaft and the seat can be reduced, the cost of replacing the shaft or the seat can be saved when the liner tube is abraded to a certain degree for replacement, and the service life of the existing liner tube is too short due to the fact that the existing liner tube is abraded too much due to poor lubricating property in the application.

Disclosure of Invention

In order to solve the problem, the utility model aims to provide a bushing pipe subassembly that lubricating property is good.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a liner tube subassembly, includes the liner tube body, the liner tube body includes the base, is equipped with the inner cover body on the base, the base on still be equipped with outer cover body, outer cover body with form the holding chamber between the inner cover body, the inner cover body on be equipped with the perforation of symmetry setting the holding intracavity is equipped with the ball, this ball is global to be passed the perforation stretches into in the hole of the inner cover body the holding intracavity fill have with the emollient of ball contact.

The lubricant is molybdenum disulfide solid lubricant.

And an elastic rubber plate is attached to the inner wall of the outer sleeve body and is in contact with the ball.

The inner part of the inner sleeve body is provided with a detention groove.

The detention groove is triangular, and the opening of the detention groove is arranged at the sharp corner of the triangular shape.

The utility model discloses a this kind of structure, interior cover body and axle when cooperating, through ball and axle contact cooperation, the axle rotates the in-process and drives the ball and rotate rotating, and the ball contacts and is infected with emollient, and emollient on the ball can be followed the rotation of axle and attached to the global effect of realizing the lubrication on the axle, just so effectively improved lubricating property.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

FIG. 1 is a cut-away view of a liner body according to an embodiment of the present invention;

fig. 2 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1 and 2, the present embodiment discloses a liner tube assembly, which includes a liner tube body 10, the liner tube body 10 includes a circular base 1, an inner sleeve 2 is disposed on the base 1, an outer sleeve 3 is further disposed on the base 1, an accommodating cavity 5 is formed between the outer sleeve 3 and the inner sleeve 2, and in the accommodating cavity, an end cap 51 is disposed at an opening of the accommodating cavity 5, perforations 4 symmetrically disposed are disposed on the inner sleeve 2, balls 6 are disposed in the accommodating cavity 5, a peripheral surface of the balls 6 penetrates through the perforations 4 and extends into an inner hole of the inner sleeve 2, a lubricant 7 contacting with the balls 6 is filled in the accommodating cavity 5, and the lubricant 7 is a molybdenum disulfide solid lubricant 7.

An elastic rubber plate 8 is stuck on the inner wall of the outer sleeve body 3, and the elastic rubber plate 8 is contacted with the ball 6. The elastic force of the elastic rubber plate 8 can drive the ball 6 to be always positioned at the position of the through hole 4, and meanwhile, the elastic rubber plate 8 can drive the lubricant 7 to be better attached to the steel ball, so that the lubricant can be more conveniently output, the shaft arranged in the inner sleeve can be always kept lubricated, and the service life of the shaft and the inner sleeve can be prolonged.

The inner part of the inner jacket body 2 is provided with a retention groove 9, the retention groove 9 is triangular, and the opening of the retention groove 9 is arranged at the sharp corner of the triangular shape. The excessive lubricant 7 can enter the retention groove 9 in the rotation process of the shaft through the retention groove 9, and the lubricant 7 in the retention groove 9 can compensate the lubrication degree of the shaft, so that the lubricant 7 and the shaft can compensate each other, and the lubrication effect and the service life are further improved.

By adopting the technical scheme, when the inner sleeve body 2 is matched with the shaft, the shaft is in contact fit with the shaft through the ball 6, the ball 6 is driven to rotate in the rotating process by the shaft, the ball 6 is in contact with the lubricant 7 and is infected with the lubricant 7, and the lubricant 7 on the ball 6 can be attached to the circumferential surface of the shaft along the rotation of the shaft to realize the lubricating effect, so that the lubricating performance is effectively improved.
