Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes, and more specifically, to a composite wear-resistant bearing bush. Background Art

[0002] The bearing bush is the part that contacts the journal of the sliding bearing, with a semi-cylindrical surface in the shape of a tile, which is very smooth. It is generally made of wear-resistant materials such as bronze and antifriction alloy. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of bearing bushes: integral and split. The integral bearing bush is usually called a bushing. There are two types of integral bearing bushes: those without oil grooves and those with oil grooves. The bearing bush and the journal adopt a clearance fit and generally do not rotate with the shaft.

[0003] The existing installation and positioning of bearing bushes usually use bolts for installation, which is a relatively cumbersome operation. The bolts are prone to loosening, reducing the stability of the bearing bush installation. Moreover, the bearing bush cannot be disassembled and replaced conveniently, making the replacement operation of the damaged bearing bush rather inconvenient and affecting the stability and practicality of the bearing bush installation.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0007] A composite wear-resistant bearing bush includes a first bearing bush and a second bearing bush. The inner walls of the first bearing bush and the second bearing bush are provided with a number of uniformly distributed arc-shaped grooves. Oil grooves are provided on the inner walls between every two arc-shaped grooves. An oil drainage layer is provided inside the oil grooves. Symmetrically arranged insertion holes are provided at one end of the first bearing bush close to the second bearing bush. Symmetrically arranged insertion blocks matching the insertion holes are provided at one end of the second bearing bush close to the first bearing bush.

[0008] Preferably, symmetrically arranged first inclined grooves are provided on both sides inside the insertion holes, and symmetrically arranged second inclined grooves matching the first inclined grooves are provided on the outer wall of the insertion blocks.

[0009] Preferably, when the first inclined grooves and the second inclined grooves are aligned, a rectangular through hole is formed, and through holes communicating with the rectangular through hole are provided on the first bearing bush and the second bearing bush.

[0010] Preferably, a rectangular clamping block matching the rectangular through hole is provided inside the through hole, and a cover plate is provided at the other end of the rectangular clamping block extending outside the through hole.

[0011] Preferably, the cover plate is provided with bolts connected to the bearing shell 1 and the bearing shell 2.

[0012] Preferably, the surfaces of the first bearing and the second bearing are both provided with annular heat sinks, and the second bearing is provided with an oil filling hole.

[0013] Preferably, a round ball is provided in the arc groove, and the inner walls of the bearing bush 1 and the bearing bush 2 are provided with a brass layer.

[0014] The beneficial effects of the utility model are as follows: through the matching design of the socket and the plug block, the existing bearing shell has the function of quick splicing, which solves the problem that the existing bearing shell needs to be replaced as a whole after a part is damaged, thus causing economic losses; and it can be freely disassembled and installed, which is convenient for transportation and inspection of internal components.
