In order to maintain the original performance of the bearing in a good condition for as long as possible, maintenance, inspection and repair are necessary to prevent accidents in the first place, ensure the reliability of operation, and improve productivity and economy.
It is best to perform maintenance on a regular basis in accordance with the operating standards of the mechanical operating conditions.
The content includes monitoring the operating status, replenishing or replacing lubricants, and regular disassembly inspections. As maintenance items during operation, there are bearing rotation noise, vibration, temperature, lubricant state, and so on.
The purpose of the lubrication of rolling bearings is to reduce the internal friction and wear of the bearing, prevent burning, and its lubricating effect is as follows:
1.Reduce friction and wear.
In the mutual contact part of the ring, rolling element and cage constituting the bearing, metal contact is prevented, and friction and wear are reduced.
2. Extend fatigue life.
The rolling fatigue life of the bearing is prolonged if the rolling contact surface is well lubricated during rotation. On the contrary, the oil viscosity is low and the lubricating oil film thickness is not good, so it is shortened.
3. Discharge the frictional heat and cool down.
The circulating oil method can use oil to dissipate heat generated by friction or heat transferred from the outside and cool. Prevent the bearing from overheating and prevent the lubricating oil from aging.
It also has the effect of preventing foreign matter from intruding into the bearing, or preventing rust and corrosion.
Bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the use conditions and purpose. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. The advantages and disadvantages of grease lubrication and oil lubrication are compared.
