Some common lubrication methods of graphite copper sleeve/self-lubricating bronze wear plate & bearings?

Generally speaking, self-lubricating bronze wear plate to sliding bearings is no need to add lubricating oil or grease as a lubricant. Graphite copper sleeve, the matrix is copper, the lubricant is graphite, in the process of relative movement with the dual shaft, the graphite in the matrix is distributed between the copper sleeve and the dual shaft as a lubricant to form a lubrication film, so as to reduce the friction coefficient to achieve the effect of self-lubrication. Of course, if it is the graphite copper sleeve used in the ordinary environment, grease can be added to improve the service life and load capacity, and some special use of self-lubricating bearings, if grease will destroy the lubrication film, resulting in a reduced self-lubrication effect.

Selection of oil-free self-lubricating graphite bronze bearing slide wear plate

In order to solve the lubrication problems of high temperature, low speed, heavy load, large dust, water shower and shock vibration in mechanical equipment, oil-free self-lubricating oilless slide bearings are selected.

1. The structure of the graphite bronze bearing slide wear plate Self-lubricating bearing is developed on the bimetal bearing of the metal friction surface of the bearing base, with holes of appropriate size and order, and embedded in molybdenum disulfide, graphite and other linear bearings to make a composite self-lubricating block inlaid on the metal sleeve , Made of composite bearings, the friction area of ​​solid lubricants reaches 25-65%.

The solid self-lubricating block can work normally at a high temperature of 280°C. However, due to its low mechanical strength and weak graphite bronze bearing slide wear plate capacity of the copper bushing, it is easy to deform, and this defect can be suppressed by embedding it in the metal hole and groove, forming the metal part to play a bearing role, and the self-lubricating block to play a lubricating role.

The lubrication mechanism of this kind of self-lubricating graphite bronze bearing slide wear plate is that during the sliding friction between the shaft and the sleeve, a part of the molecules of the self-lubricating material is transferred to the metal surface of the shaft, filling the small unevenness and forming a relatively stable solid lubricating film. , causing the friction between the solid lubricating films to prevent the adhesive wear of the shaft and the sleeve.

This rational combination combines the respective complementary advantages of copper alloys and non-metallic wear-reducing materials, and is especially suitable for motion amplitudes in oil-free, high temperature, high load, low speed, anti-fouling, anti-corrosion, strong radiation environments, and It is used under special working conditions where it is impossible to add lubricating grease at all due to water or other solutions.

2. The area occupied by the self-lubricating block is related to the running speed and the graphite bronze bearing slide wear plate strength. The running speed is low; the bearing strength is high, and the metal occupied area should be larger. Auto Bearing Model Query Software Bearing World

For example, the self-lubricating block of the traveling wheel bearing of the ingot-holding trolley occupies about 25% of the area. The shaft graphite bronze bearing slide wear plate of the ingot-pulling mechanism should be fully lubricated, and the pressure bearing strength is not large. The area of ​​the self-lubricating block is about 65%. Auto Bearing Model Query Software Bearing World

3. Technical requirements for bushing materials. The bushing should be made of alloy copper. The bushing should have high hardness. Generally, heat treatment is required, and its hardness should not be lower than HRC45. Bearing Enterprise Navigation

4. The geometry and inlay requirements of the self-lubricating block. The shape of the self-lubricating block is cylindrical and rectangular. The self-lubricating block can be cylindrical according to the size of the occupied area, otherwise, it can be rectangular. Regardless of the shape, it must be securely mounted to prevent it from falling off during operation. Bearing Enterprise Navigation

5. The matching clearance between the bushing and the shaft The linear expansion coefficient of the self-lubricating block is about 10 times that of steel. In order to adapt to the temperature change of the graphite bronze bearing slide wear plate, the gap between the shaft and the bushing is increased from 0.032 to 0.15MM to 0.45 to 0.5MM from the original four-stage dynamic fit of metal parts (D4/DC4).

The self-lubricating block protrudes from the bushing metal by 0.2-0.4MM on one side of the friction pair. In this way, the graphite bronze bearing slide wear plate will be fully lubricated during the initial running-in period of operation and reduce the consumption of power dragging power.
