Understand the advantages of graphite copper sleeve

The working principle of the graphite copper sleeve bearing

The working principle of the graphite copper sleeve bearing is to use its own oil absorption and oil discharge process to achieve the principle of self-lubrication. Generally, the graphite copper sleeve generates heat during the working process, so the oil originally sucked in will release the oil after being heated. To achieve the purpose of self-lubricating.

Graphite copper sleeve is a kind of solid lubricant with well-arranged and appropriate pores developed on the friction surface of the copper sleeve as the metal matrix, and embedded with graphite or molybdenum disulfide.

Graphite copper sleeve self-lubricating bearing

Generally, solid lubricants account for 20-30% of the friction surface area. The lubrication principle of graphite copper sleeve self-lubricating bearings is that during the sliding friction process between the shaft and the bearing, a part of the graphite particles is transferred to the friction surface of the shaft and the bearing to form a The solid lubricating diaphragm with a relatively stable layer prevents direct adhesive wear between the shaft and the bearing.

What are the advantages of graphite copper sleeve? Let’s get to know!

No oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used without maintenance or less maintenance.

 

Good wear resistance, small friction coefficient, long service life.With proper amount of elastoplasticity, the stress can be distributed on a wider contact surface to improve the bearing capacity of the bearing.

 

The static and dynamic friction coefficient is similar, which can eliminate the creep at low speed, so as to ensure the working accuracy of the machine.The machine can reduce vibration, reduce noise, prevent pollution, improve working conditions.

 

Graphite copper sleeve can form transfer film in the process of operation, play a role in protecting the grinding shaft, no shaft bite phenomenon.For grinding shaft hardness requirements are low, the shaft without quenching and tempering treatment can be used, thus reducing the processing difficulty of the relevant parts.Graphite copper sleeve skill characteristics are constantly improving.
