The lubrication of skirting and rounding machine plays an important role in the process of using the machine. So how can we do a good job in the lubrication work of the skirting and rounding machine? Let's have a simple understanding of the following points when using lubricating oil:
1. When the surface of the friction surface is rough, the oil with higher viscosity should be used
2. For non liquid friction prone to occur, such as variable load, unequal speed or often start, stop and other mechanisms, should use a larger viscosity of lubricating oil;
3. When the working temperature is high, the viscosity of oil should be increased;
4. The higher the pressure per unit area, the higher the viscosity of lubricating oil
5. The higher the rotation or sliding speed of the rotary cutter, the lower the viscosity of lubricating oil;
6. Grease: generally known as yellow dry oil, it has the advantages of simple sealing, no need to add and change frequently, wide adaptability, and is not easy to lose in the vertical plane. However, the lubricating grease has poor fluidity, low thermal conductivity and can not be used as circulating lubricant. In addition, it has high friction resistance and low mechanical efficiency. According to the above characteristics, attention should be paid to the selection of grease, Grease is mainly used in low speed, heavy load, inconvenient to frequent oiling and low requirements for use; in the mechanism with rough joint surface and reciprocating motion, in order to enhance the lubrication effect, a proper amount of graphite powder can be added into the grease
