Abstract

The invention discloses an adjustable combined bushing of a high-lubrication inner bushing. The adjustable combined bushing comprises the inner bushing and an outer bushing, the outer bushing is sleeved on the inner bushing in a clearance fit manner; the neck bush is a combined bush and comprises an upper bush, a lower bush and a plurality of middle bushes; the outer bushing is provided with a three-stage stepped hole with a small upper part and a large lower part; a shaft shoulder is arranged at the upper end of the outer wall of the upper bushing; a stepped hole in the upper end of the outerbushing is clamped and sleeved on a shaft shoulder at the upper end of the outer wall of the upper bushing; the lower part of the lower bushing is provided with an outwards-turned flange edge, and the outwards-turned flange edge at the lower part of the lower bushing is embedded in and fixedly connected with a stepped hole at the lower end of the outer bushing; and the middle bushing is made of amaterial with a lubricating function. The axial length of the neck bush can be adjusted according to needs, and the lubricating performance is good.

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 inner 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 bushing of a high-lubricating inner bushing that can adjust the axial length of the inner bushing as required. [0004] The present invention achieves technical goals through the following technical solutions. [0005] High-lubricating inner bushing adjustable combined bushing, including inner bushing and outer bushing; the outer bushing...
