The tribological properties of locomotive bearing forgings under different working conditions, including different load, speed and lubrication conditions, are studied in this paper. Through the analysis of the experimental results, the influence of different working conditions on the tribological properties of bearing forgings is revealed, which provides a theoretical basis for the optimization design and operation of the locomotive.
As a key part of locomotive and rolling stock, the tribological properties of locomotive bearing forgings will change under different working conditions. In order to understand these changes and improve the operating efficiency and safety of locomotive, the tribological properties of bearing forgings under different working conditions are studied in this paper.
In this paper, the tribological performance of locomotive bearing forgings is tested by friction and wear testing machine. By changing the load, speed and lubrication conditions, the operation conditions under different working conditions are simulated.
The influence of load on tribological properties: With the increase of load, the friction coefficient and wear amount of bearing forgings are on the rise. This is because high loads can lead to increased contact pressure, which increases wear.
The influence of speed on tribological properties: The influence of speed change on the tribological properties of bearing forgings is more complex. At low speed, the friction coefficient decreases with the increase of speed. At high speed, due to the action of friction heat, the friction coefficient will increase with the increase of speed.
The influence of lubrication conditions on tribological properties: Good lubrication conditions can effectively reduce the friction coefficient and wear amount of bearing forgings. In the case of lack of oil or poor lubrication, the tribological properties of bearing forgings will be significantly reduced.
According to the experimental results, the tribological properties of locomotive bearing forgings under different working conditions are different. In order to improve the operating efficiency and safety of the locomotive, it is necessary to select the appropriate bearing forgings according to the actual operating conditions, and optimize the lubrication system design to ensure good lubrication conditions.
In this paper, the tribological properties of locomotive bearing forgings under different working conditions are studied, and the effects of load, speed and lubrication conditions on the tribological properties of bearing forgings are revealed. These results provide a theoretical basis for the optimization of locomotive design and operation, and help to improve the efficiency and safety of locomotive operation.
