Novel shaft sleeve structure
阅读说明:本技术 一种新型轴套筒结构 (Novel shaft sleeve structure ) 是由 赵正峰 于 2020-07-21 设计创作,主要内容包括:本发明为一种新型轴套筒结构,属于连接用轴套,主要包括轴套及其内嵌入的镶套,其特征在于:镶套的外侧设置有一个与轴套端面配合的垫套,该垫套与镶套一体式加工成形,形成一个带外沿的套筒结构,垫套与轴套之间通过螺栓紧固。由于镶套与轴套之间仅需紧密配合,通过螺栓装配在一起,避免了过盈配合带来的拆装不便。同时增设的垫套保证了轴套端面不受磨损,能有效提高产品使用寿命,降低维修费用。(The invention relates to a novel shaft sleeve structure, which belongs to a shaft sleeve for connection, mainly comprises a shaft sleeve and an embedded bushing embedded in the shaft sleeve, and is 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. 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.)
1. The utility model provides a novel axle sleeve structure, mainly includes axle sleeve (1) and the cover (2) of inlaying in it, its characterized in that: the outer side of the bushing (2) is provided with a pad cover (3) matched with the end face of the shaft sleeve (1), the pad cover (3) and the bushing (2) are integrally processed and formed to form a sleeve structure with an outer edge, and the pad cover (3) and the shaft sleeve (1) are fastened through bolts (4).
2. The novel shaft sleeve structure as claimed in claim 1, wherein: the joint of the cushion cover (3) and the embedding cover (2) is provided with a circle of boss (7) on the inner side, and the corresponding position of the shaft sleeve (1) is provided with a concave platform matched with the boss (7).
Technical Field
The invention relates to a shaft sleeve for connection, in particular to a shaft sleeve structure embedded with an embedded sleeve.
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
The invention aims to provide a novel shaft sleeve structure assembled through bolts, and simultaneously protect the inner wall and the end face of a shaft sleeve.
The invention is realized by the following steps:
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.
After the structure is adopted, the bushing and the shaft sleeve only need to be tightly matched and are assembled together through the bolt, so that the inconvenience in assembly and disassembly caused by interference fit is avoided. 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.
