How much does lubrication affect the life of roller chains?
Lubrication has a vital impact on the life of roller chains. In industrial applications, roller chains are key components for transmitting power, and their performance and life depend largely on lubrication conditions. The following is a detailed analysis of the impact of lubrication on the life of roller chains:

1. Reduce wear and fatigue damage
Lubrication can significantly reduce the wear and fatigue damage of roller chains during operation. According to research by Zhang Ansheng and others, the thickness and shape of the lubricating oil film have a significant effect on the lubrication behavior of rollers and bushings. Both experimental and theoretical results show that an increase in roller diameter leads to an increase in lubricating oil film thickness, thereby reducing wear

2. Reduce friction and temperature
Good lubrication conditions help reduce friction and temperature in roller chains. Friction not only causes energy loss, but can also accelerate chain wear. By reducing friction, lubrication can extend the service life of roller chains and reduce the risk of damage caused by overheating

3. Prevent the intrusion of contaminants
Lubricants can also form a protective film on the surface of roller chains to prevent the intrusion of contaminants such as dust and moisture. These contaminants may accelerate the wear and corrosion of the chain, thus shortening its service life.

4. Affecting the storage of grease
The meshing shock, vibration, stress conditions and speed of the roller chain affect the storage of grease in the chain, thus affecting the wear resistance of the chain. Therefore, ensuring correct lubrication not only helps to reduce wear, but also helps to maintain the correct distribution of grease in the chain.

5. Improving the durability of the chain
According to the data provided by the Tsubaki Industrial Machinery Product Information Website, Lambda chains (oil-free chains) can maintain a long service life without oil supply, which shows the importance of lubrication to the life of roller chains.
The sleeves of this chain use oil-containing bearings, and the lubricating oil is infiltrated into the pores of the porous sintered sleeves. It can be used without additional oil supply, reducing maintenance costs and improving production efficiency.

6. Extending service life
Good lubrication can significantly extend the service life of roller chains. According to technical information provided by Norelem, a chain drive with adequate lubrication, maintenance and correct use can work for up to 15,000 hours. This emphasizes the importance of regular and correct lubrication.

Conclusion
In summary, lubrication has a significant impact on the life of roller chains. Proper lubrication can reduce wear, reduce friction and temperature, prevent the intrusion of contaminants, affect the storage of grease, and ultimately extend the service life of the chain. Therefore, in order to ensure the best performance and longest life of roller chains, it is necessary to pay attention to the implementation and management of lubrication.
