Abstract

The invention provides a wear-resistant bush, which relates to the field of mechanical parts. The wear-resistant bush includes a bush main body, and the inner wall of the bush main body is provided with a plurality of lubricating oil passages extending in a spiral shape; a plurality of The starting ends of the lubricating oil passages are evenly arranged along the circumference of the bushing body; the pitches of the plurality of lubricating oil passages are respectively equal; the plurality of lubricating oil passages intersect each other; the plurality of lubricating oil passages The beginning and the end of the passage are closed respectively; the bushing body is also provided with an annular oil storage passage, and the rotation axis of the oil storage passage is collinear with the rotation axis of the bushing main body; the oil storage passage and the The plurality of lubricating oil passages are connected through respectively. The wear-resistant bush provided by the invention solves the technical problems of the traditional bush such as uneven distribution of oil passages, insufficient oil supply and poor sealing performance.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a wear-resistant bushing. Background technique [0002] In the prior art, articulated connections (pin-shaft connections) are often used in construction machinery, resulting in multiple friction pairs that require intermittent pressure lubrication. A friction pair is a friction system formed by friction between two objects in contact. The friction pair is the most important element of the face seal. The life of the seal and the quality of its work are all related to it. All other structural elements of the face seal serve the friction pair and their working quality also depends on how well the pair works to achieve optimal conditions. The name of the friction pair itself indicates that the work of the element is the relative sliding of two parts. Their friction produces wear, heat, fluid leakage and other phenomena. There are many classification methods for friction, and the ...
