Abstract

The utility model relates to a novel axle sleeve structure belongs to the axle sleeve for the connection. The sleeve mainly comprises a shaft sleeve and an embedded bushing, and is characterized in that a cushion cover matched with the end face of the shaft sleeve is arranged on the outer side of the bushing, the cushion cover and the bushing are integrally processed to form a sleeve structure with an outer edge, and the cushion cover and the shaft sleeve are fastened through bolts. Because only need closely cooperate between inlay cover and the axle sleeve, through the bolt assembly together, avoided the dismouting inconvenience that interference fit brought. Meanwhile, the additionally arranged cushion cover ensures that the end surface of the shaft sleeve is not abraded, the service life of a product can be effectively prolonged, and the maintenance cost is reduced.

Description

Novel shaft sleeve structure

Technical Field

The utility model relates to a connect and use axle sleeve, especially an axle sleeve structure that has the inlay cover to imbed.

Background

Bushings are widely used in mechanical transmission arrangements. The axle sleeve that uses in the existing market is straight barrel casing, inlays cover and adopts interference fit with the axle sleeve, through the embedding mode, makes the two assemble together. The bushing is made of wear-resistant materials and is mainly used for protecting the shaft sleeve and avoiding the abrasion between the inner wall of the shaft sleeve and the transmission shaft. The assembly mode has strict requirements on the sizes of the bushing and the product, the assembly needs to be completed by using larger pressure, and the disassembly is more laborious. When the bushing is worn in use, the binding force between the bushing and the shaft sleeve is reduced, and the bushing and the shaft sleeve can move relatively, so that the inner wall of a product is worn. In addition, the bushing is completely embedded, only the inner wall of the shaft sleeve is protected, the outer end face of the shaft sleeve is not protected, the outer end face of the shaft sleeve is abraded with a rotating connecting frame, and the service life of the whole product is influenced.

Disclosure of Invention

An object of the utility model is to provide a through the novel axle sleeve structure of bolt assembly, protect the inner wall and the terminal surface of axle sleeve simultaneously.

The utility model discloses a realize like this:

the utility model provides a novel axle sleeve structure, mainly includes the bush of inlaying of axle sleeve and embedding in it, its characterized in that: the outer side of the bushing is provided with a cushion cover matched with the end face of the shaft sleeve, the cushion cover and the bushing are integrally processed to form a sleeve structure with an outer edge, and the cushion cover and the shaft sleeve are fastened through bolts.

The inner side of the joint of the cushion cover and the embedding sleeve is provided with a circle of boss, and the corresponding position of the shaft sleeve is provided with a concave platform matched with the boss.

The utility model adopts the above structure after, only need closely cooperate between inlay cover and the axle sleeve, be in the same place through the bolt assembly, it is inconvenient to have avoided the dismouting that interference fit brought. After the bushing is worn, the fastening force of the bolt is not influenced, the bushing and the shaft sleeve cannot move relatively, and the inner wall of the shaft sleeve is prevented from being worn. Meanwhile, the additionally arranged cushion cover ensures that the end surface of the shaft sleeve is not abraded, the service life of a product can be effectively prolonged, and the maintenance cost is reduced.

In the attached drawing, 1 is a shaft sleeve, 2 is an embedding sleeve, 3 is a cushion cover, 4 is a bolt, 5 is a transmission shaft, 6 is a connecting frame, and 7 is a lug boss.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

The utility model relates to a novel axle sleeve structure, mainly used mechanical transmission field. As shown in fig. 1, the present invention mainly comprises a shaft sleeve 1 and an embedded bushing 2, wherein the bushing 2 is tightly fitted with the shaft sleeve 1. The outer side of the insert sleeve 2 is provided with a cushion cover 3, the cushion cover 3 and the insert sleeve 2 are integrally processed and formed, as shown in figure 2, a sleeve structure with an outer edge is formed, and the strength of a single edge is increased. The cushion cover 3 corresponds to and is matched with the end surface of the shaft sleeve 1. The cushion cover 3 and the shaft sleeve 1 are fastened through bolts 4, and 10.9-grade high-strength bolts 4 can be adopted. The bolt 4 not only ensures the firm matching of the two, but also avoids the relative movement between the shaft sleeve 1 and the bushing 2; meanwhile, the parts are convenient to disassemble, assemble and replace.

As shown in figure 2, in the integrated processing of the cushion cover 3 and the embedding sleeve 2, a circle of boss 7 is arranged on the inner side of the joint of the cushion cover and the embedding sleeve, so that the stress of the joint of the cushion cover and the embedding sleeve is increased, and the fracture in the long-term use process is avoided. And a circle of concave platforms which are tightly matched with the convex platforms 7 are arranged at the corresponding position of the shaft sleeve 1, namely outside the end angle of the shaft sleeve 1.

As shown in fig. 3, the driving shaft 5 is engaged with the insert 2, and the driving shaft 5 only wears the insert 2 during rotation, thereby protecting the sleeve 1. 5 end connection drive frames of transmission shaft, the setting of cushion cover 3 is between link 6 and axle sleeve 1, and link 6 only can cause wearing and tearing to cushion cover 3 at rotatory in-process to protection axle sleeve 1. The cushion cover 3 and the insert cover 2 are made of 20CrMo materials, and are carburized and quenched to improve the wear resistance.

The utility model discloses be not limited to above-mentioned product structure, adopt with the utility model discloses the same or approximate structure, and other structural design who obtains are all in the utility model discloses a protection within range.
