Embodiment Construction

[0024] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] Such as figure 1 As shown, the structure of the copper sleeve used on the precision self-lubricating bearing includes an outer iron-based cylinder 1. External chamfers are respectively provided at both ends of the outer wall of the outer iron-based cylinder 1, and outer chamfers are respectively provided at both ends of the inner wall of the outer iron-based cylinder 1. There are internal chamfers which facilitate final assembly, as well as assembly of internal components.

[0026] Reaming holes 11 are respectively provided at both ends of the inner wall of the outer iron-based cylinder body 1 , and the axis lines of the two reaming holes 11 coincide.

[0027] It also includes an inner copper-based middle cylinder 2 and tw...

Abstract

A copper sleeve structure for a precision self-lubricating bearing comprises an outer iron-based cylinder body, two ends of the inner wall of the outer iron-based cylinder body are respectively provided with an expanded hole, an inner copper-based middle cylinder and two inner copper-based end cylinders are included, the inner copper-based middle cylinder is inserted into the outer iron-based cylinder body, two ends of the inner copper-based middle cylinder are respectively flush with the hole bottoms of the expanded holes, one inner copper-based end cylinder is inserted into one expanded hole, the other inner copper-based end cylinder is inserted into the other expanded hole, a plurality of first arc-shaped notches circumferentially distributed are formed in two ends of the inner copper-based middle cylinder, the first arc-shaped notches arranged at one end of the inner copper-based middle cylinder are distributed in a staggered manner with the first arc-shaped notches arranged at theother end of the inner copper-based middle cylinder, the inner end of each inner copper-based end cylinder is respectively provided with second arc-shaped notches corresponding to the corresponding first arc-shaped notches one by one, a plurality of arc-shaped locking blocks with L-shaped transverse sections are further included, one end of each arc-shaped locking block is clamped in the corresponding first arc-shaped notch, and the other end of each arc-shaped locking block is clamped in the corresponding second arc-shaped notch.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a copper sleeve structure for precision self-lubricating bearings. Background technique [0002] Copper sleeve is a commonly used mechanical connector. [0003] The current copper sleeve is generally a one-piece cylindrical structure. In order to improve self-lubricating performance, structures such as blind oil storage holes or oil tanks are designed in the copper sleeve. [0004] The cost of the copper sleeve of this copper material is relatively high. [0005] And there is the copper sleeve of composite material that the inventor designs, and for the copper sleeve of composite material, its process requirement is higher during compounding. Contents of the invention [0006] The object of the present invention is to address the above problems and provide a copper sleeve structure for precision self-lubricating bearings that can solve the above technical proble...
