The Processing And Movement Characteristics Of Bushing
Thick-walled bushing can be cast, in order to improve the friction performance, can be cast in
the bearing surface of a bearing alloy. In order to make the bearing alloy and bearing attached to
the well, often in the inner surface of the bearing on the various forms of tenon, groove or thread.
Thim-walled bushings can be bimetallic continuous rolling process and other large-scale production.
Powder metallurgy is the powder of iron or copper and other basic materials mixed with
graphite, and then pressed sintering forming. The pores can be stored lubricants, called oil bearing.
The bushing material is usually softer, the inner cylindrical surface should not be processed
by grinding, can be boring, King Kong boring, scraping or grinding processing. Grinding should not
not be used with the shaft diameter with the method of research, but should use a special size and
size of the same hole diameter rod. Scraping for the part of tile bearing, scraping with a wide
blade scraper. Hand scrape, scratches should be shallow. The inner surface of the complex shape of
the bearing, should be based on the specific shape of the use of special boring method.
Sliding bearing work, between the bearing pad and the shaft requires a thin layer of oil film
from the lubrication effect. If there is a direct friction between the bearing pad and the shaft,
the friction will produce a very high temperature. Although the bearing pad is made of a special
high temperature resistant alloy material, the high temperature generated by direct friction is
still sufficient to burn it. Bearings may also be due to the load is too large, the temperature is
too high, there are impurities in lubricants or viscosity abnormalities and other factors caused by
burning tile. After the burning of the sliding bearing on the damaged.
