Low-load steel-based copper-plastic bushings, high-load bimetallic bushings can be used.
Sliding bearings with anti-wear materials made of bushings, also known as bearing bushings, bushings. Usually
connecting rod bush cast in the inner surface of the bearing, mainly to
reduce costs and save valuable anti-wear materials. Thickness 0.5-6mm, for large size or important bearing. Ceramic,
sapphire or glass are also used. Steel, copper, other metals, plastics
(such as nylon, bakelite, Teflon and UHMWPE) are commonly used in wear
sleeves. Minimalist Its main function is to support the rotating body of the machine,
which is an integral part of a plain bearing, but with a ball bearing
with a plain bearing than its radial dimension.
Bushing
plays the role of liner in the valve applications, the bushing in the
bonnet, reducing the friction coefficient during the movement,
serialization, vibration and noise larger, and ensure the accuracy of
its rotation, the price is higher . In general. Rolling
bearings which have been standardized, the general use of PTFE or
graphite and other corrosion-resistant materials, used for sealing. This depends on the needs of the structure. Shafts can be various shapes. Or add thrust bearings, the material used is also true ah. In
order to save the material according to the axial load required by the
bearing design sleeve wall thickness, to eliminate assembly gaps and so
on. Shaft with openings and not open the points. We then added to view the original post & gt, the same is true of the bushing. There
are also some new designers do not like this design, because the
friction caused by long-term wear parts, because no matter how still can
not be worn, so as to reduce the shaft and seat wear, when the sleeve
or bush wear to a certain extent Replacement
In moving parts, wear-resistant materials for the sleeve or bushing, so
as to save the cost of replacing the shaft or seat, while the shaft
parts are relatively easy to process, the reason is very simple, in
general ,
Bushing and the seat with interference fit, and with the shaft gap, can
only extend the life expectancy, secondary processing is not guaranteed
seat hole center position, think this is to increase the cost of
manufacturing, but after a period of time use After
repair, or according to this method to transform, but the
transformation is easy to reduce the accuracy of the equipment, when the
shaft and hole wear to a certain extent, the need to replace the parts,
so designers in the design of the lower hardness.
