Graphite copper sleeve, also known as Rongchang graphite copper sleeve, takes copper sleeve as the base, and then inlays graphite and PTE self-lubricating materials, so that it does not need to be refueled and maintained during the use. The products are widely used in high load, intermittent or swing motion, such as steam locomotive production line, hydraulic turbine, reservoir work / accident door, plastic machinery, etc. According to the working conditions, various types of copper alloy can be provided. So what are the characteristics of self lubricating graphite copper sleeve?
1. It can reduce vibration, reduce noise, prevent pollution and improve labor conditions.
2. In the process of operation, transfer film can be formed, which can protect the grinding shaft without shaft bite.
3. No oil lubrication or less oil lubrication, suitable for places where it is difficult to refuel or cannot be filled. It can not be maintained or maintained less when using.
4. The wear resistance is good, the friction coefficient is small and the service life is long.
5. With proper elastic-plastic properties, the stress can be distributed on a wider contact surface, and the bearing capacity can be improved.
6. The static and dynamic friction coefficient is similar, which can eliminate the creeping at low speed, thus ensuring the working accuracy of the machine.
7. The hardness of grinding shaft is low, and the shaft without tempering can be used, which reduces the processing difficulty of related parts. The oil-free self lubricating graphite copper sleeve products are mainly used in automobile chassis, metallurgy machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, rolling equipment, etc.; for example: printing machine, textile machine, tobacco machinery, micro motor, automobile, motorcycle and agricultural and forestry machinery, etc.
