The invention discloses a method for improving performance of a bearing bush steel backing. The method comprises the following steps that S1, rolling treatment is conducted, specifically, a platy bearing bush
raw material passes through a gap between a pair of rotating rollers, the platy bearing bush
raw material is compressed by the rollers, and thus the section of the platy bearing bush
raw material is reduced; S2, press-bending shaping is conducted, specifically, the rolled platy bearing bush raw material is bent in a pressed mode through a bending press, and thus the rolled platy bearing bush raw material is in a semicircular shape; and S3, low-temperature heat treatment is conducted, specifically, the platy bearing bush raw material subjected to press-bending shaping is put into a heat treatment
machine to be heated, after heating, dimensional
processing and
coating treatment are conducted, and thus a finished bearing bush is obtained. According to the method for improving the performance of the bearing bush steel backing, the
hardness of the bearing bush steel backing can be adjusted and improved, the deformation stability of the bearing bush is improved, by controlling the
hardness of the steel backing, the design requirement is met, the dimensional change amount of the bearing bush is decreased, the stability of
assembly and operation is improved, and the problem that the strength of an existing bearing bush steel backing is low, consequently, the bearing bush steel backing is prone to deforming in the
assembly and operation processes, and normal use is affected issolved.
