Graphite copper sleeve, also known as Rongchang graphite copper sleeve, uses the copper sleeve as the matrix, and then inlays the self-lubricating materials graphite and PTE, so that it does not need to be oiled and maintained during use. Products are widely used in high-load, intermittent or swing motions, such as steam and locomotive production lines, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the working conditions, various types of copper alloys can be provided. So what are the characteristics of the self-lubricating graphite copper sleeve?
1. It can reduce vibration, noise, pollution, and improve working conditions.
2. A transfer film can be formed during operation to protect the grinding shaft without the phenomenon of shaft biting.
3, no oil or less oil lubrication, suitable for places where it is impossible to refuel or it is difficult to refuel, and can be used without maintenance or less maintenance.
4. Good wear resistance, low friction coefficient and long service life.
5. There is an appropriate amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity of the bearing.
6. The static and dynamic friction coefficients are similar, which can eliminate crawling at low speeds, thereby ensuring the working accuracy of the machine.
7. The hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thereby reducing the processing difficulty of related parts. Oil-free self-lubricating graphite copper sleeve products are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc.; for example: printing machines, textile machines, tobacco machinery, micro motors, automobiles, motorcycles Vehicles and agricultural and forestry machinery, etc.
