Abstract

The invention discloses a high-lubricating adjustable combined bush with an outer bush. The combined bush comprises an inner bush and the outer bush. The outer bush is in clearance fit with and sleeves the inner bush. The outer bush is composed of an upper outer bush body, a middle outer bush body and a lower outer bush body which are overlapped from top to bottom. As the further improvement, themiddle outer bush body is a bush body made of a material with a lubricating function. The inner bush is a combined type bush and comprises an upper inner bush body, a lower inner bush body and a plurality of middle inner bush bodies. The upper outer bush body is provided with a big-end-down spigot hole. The upper end of the outer wall of the upper inner bush body is provided with a shaft shoulder.A spigot at the upper end of the outer bush is clamped on the shaft shoulder at the upper end of the outer wall of the upper inner bush body. The lower end of the lower outer bush body is provided with a spigot hole. The lower portion of the lower inner bush body is provided with an outwards-turned flanged edge. The outwards-turned flanged edge at the lower portion of the lower inner bush body isembedded in and fixedly connected with the spigot hole in the lower end of the lower outer bush body. The middle inner bush bodies are bush bodies made of a material with a lubricating function. Thehigh-lubricating adjustable combined bush can adjust the axial length of the inner bush and the outer bush according to needs, and is good in lubricating property.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a composite bush. Background technique [0002] The combined bushing is a commonly used structure in the field of mechanical technology, and generally includes an inner bushing, an outer bushing, and the outer bushing is fitted on the inner bushing. The main defect of the existing composite bushing is that the axial length of the outer bush of the composite bushing is fixed and cannot be adjusted as required. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an adjustable combined bush with a high-lubricating outer bush that can adjust the axial length of the outer bush according to needs. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The high-lubricating outer bushing adjustable combined bushing includes an inner bushing and an outer bushing; the outer...
