Axle Sleeve Wear Degree

Axle Sleeve Wear degree

The primary function of the bearing is to support the mechanical rotating body, which reduces the collision factor of the graphite mosaic lubrication bearing during its movement and ensures its inversion accuracy.

According to the nature of the collision elements of the copper alloy alloy is not the same, the bearings can be divided into two categories of rolling bearings and sliding bearings. During the rolling bearing is now standardized, serialized, but compared with its sliding bearing its radial scale, vibration and noise, the price is higher.

Rolling bearings are usually composed of outer rings, inner rings, tumblers and retainers. The strict copper-based solid inlaid lubricating bearings are made of outer rings, inner rings, tumblers, retainers, seals and lubricants. constitute. Mainly with outer ring, inner ring, rolling body can be determined for rolling bearings. According to the shape of rolling body, rolling bearings are divided into ball bearings and roller bearings two categories.

Shaft sleeve is set on the shaft of the cylindrical mechanical parts, is a sliding bearing a number of some. Single from the degree of wear in terms of steel sets higher than the copper sets, the actual use of steel towels rarely used, will wear the shaft quickly. Usually in the planning selection of bearing pad bearings, shaft and sleeve will use two kinds of raw materials. Because the shaft is rolling, the bearing pad is fixed, in the rolling gear pump bearings will inevitably friction, and then the shaft and bearing wear. And the shaft of the processing and the ease of installation and installation of sliding oil-free bushings SF-1 difficulty contrast, the bearing is fixed maintenance may replace the comparison is simple, so in the selection of raw materials when the steel sleeve bearing the selection of the pad material soft, Tin bronze, aluminum and iron bronze, tin zinc lead bronze, etc., according to different conditions of use to choose a different kind of copper alloy, and the choice of raw materials will be harder or more wear-resistant. So simply in all the shaft - bearing with the shaft will use steel materials, the bearing will use copper material. Precisely speaking: babbitt, is a friction-reducing properties of tin and lead-based bearing alloy. This is because the copper material as steel materials wear, in order to protect the shaft, will use copper material as a bearing.

Copper sleeve material as follows:

ZCuSn10Pb1

High hardness, excellent wear resistance, easy to produce bite the phenomenon, have better casting performance and cutting performance, in the atmosphere and fresh water has good corrosion resistance.

Can be used for high load (20Mpa below) and high sliding speed (8m / s) work under the wear parts, such as connecting rods, bushings, bearings, gears, worm gear and so on.

ZCuSn10Pb5

Corrosion resistance, especially for dilute sulfuric acid, hydrochloric acid and fatty acids.

Structural materials, corrosion resistant, acid resistant parts and crusher bushings, bushings.

ZCuPb10Sn10

Lubricating properties, wear resistance and corrosion resistance, suitable for use as bimetallic casting materials.

Vehicle bearings, the load peak of 100Mpa internal combustion engine double metal bearing, and piston pin sets, such as friction tablets.

ZCuPb15Sn8

In the absence of lubricant and water quality lubricant conditions, sliding and self-lubricating performance, easy cutting, casting performance is poor, good corrosion resistance of dilute sulfuric acid.

Surface pressure, and side pressure bearings, can be used to manufacture cold-rolled copper cooling pipe, impact load of 50Mpa parts, internal combustion engine bimetallic bush, mainly for the maximum load of 70Mpa piston pin sets, acid accessories The

ZCuZn38Mn2Pb2

Have good mechanical properties and corrosion resistance, good wear resistance, good cutting performance.

General use of structural parts, ships, instruments, etc. The use of simple casting, such as sleeves, bushings, bearings, sliders and so on.
