Bearing, as the core component of mechanical transmission, carries the force and torque of rotational motion, so its running state directly affects the performance and life of the equipment. Lubrication is one of the key factors for bearings to maintain good operation.
First, the importance of bearing lubrication
1. Reduce friction and wear: When the bearing is working, friction is inevitable, and appropriate lubrication can reduce the coefficient of friction, reduce wear, and extend the service life of the bearing.
2. Cooling and sealing: the lubricant can form a protective film between the bearing and the external environment, which plays the role of sealing and cooling, effectively reducing the working temperature of the bearing and improving work efficiency.
3. Reduce noise: Good lubrication can reduce the noise generated during bearing operation and improve the smoothness and comfort of the equipment.
Second, bearing lubrication method
1. Grease: grease is one of the most common lubrication methods, it is composed of base oil and additives, has good viscosity and adhesion, suitable for high-speed, high temperature and sealed bearings.
2. Lubricating oil: lubricating oil is suitable for high-speed bearings and continuous operation of the machine, it has good fluidity and cooling performance, can form a uniform oil film in the bearing, reduce friction.
3. Solid lubricants: solid lubricants are usually applied to bearings with high temperature, high load and low speed, such as molybdenum, copper, lead and other solid particles, which can form a uniform lubricating film on the bearing surface to reduce friction and wear.
