Lubricating oil selection: a key part of gearbox bearing lubrication

In the lubrication process of transmission bearings, lubricant selection is a crucial decision that cannot be ignored. The selection of oil is not only related to the lubrication effect of the bearing, but also directly affects the life of the gear, the sliding efficiency of the synchronizer or clutch, and the oil churning loss. Therefore, when selecting lubricants, we need to consider a variety of factors to ensure that the transmission bearings can receive the best lubrication protection.

Improving gear life is one of the key factors to consider when selecting lubricants. As the core component of the gearbox, the life of the gear is directly related to the reliability and durability of the entire gearbox. Therefore, when selecting lubricants, we need to choose oils with excellent anti-wear and anti-fatigue properties to reduce wear and damage of gears during operation, thereby extending their service life.

Ensuring the sliding efficiency of the synchronizer or clutch is also an important factor to consider when selecting lubricants. Synchronizers and clutches are key components in the gearbox to achieve smooth shifting. Their slipping efficiency directly affects the smoothness of shifting and driving comfort. Therefore, when selecting lubricants, we need to choose oils with good lubrication and friction properties to ensure that the synchronizer and clutch can maintain efficient slipping during the gear shift process.

Reducing churning losses is also an aspect that needs to be considered when selecting lubricants. Churning loss refers to the energy loss caused by the stirring of lubricating oil during the operation of the gearbox. Excessive churning loss will not only reduce the transmission efficiency of the gearbox, but also increase fuel consumption and operating costs. Therefore, when choosing lubricating oil, we need to choose those oils with lower viscosity and good fluidity to reduce oil churning losses and improve the transmission efficiency of the gearbox.

The selection of lubricating oil is an important part of gearbox bearing lubrication. When selecting oil, we need to comprehensively consider multiple factors such as improving gear life, ensuring synchronizer or clutch slipping efficiency, and reducing oil churning losses to select the most suitable lubricant for the gearbox bearings. Through reasonable lubricant selection, we can ensure that the gearbox bearings are well lubricated and protected, thereby improving the reliability and durability of the gearbox and providing a strong guarantee for the smooth operation of the vehicle.
