By adding grease between the meshing surfaces of the gear teeth, direct contact between the gears can be avoided, friction loss can be reduced, the running condition of the gears can be greatly improved, and normal operation and expected life can be maintained. The selection of gear grease is related to the temperature of the use environment of the reduction gearbox. The higher the temperature, the lower the viscosity of the lubricating oil. Therefore, it is necessary to select greases with different viscosity according to the temperature, and take into account the difference in seasonal temperature. Viscosity, of course, also needs to consider the effect of temperature rise in the working state of the gear reducer. The higher the power of the reducer, the greater the temperature rise of the gear, the longer the working time, the higher the heat, and the viscosity of the grease at high temperatures The lower.
Baoxing Lubricant Engineers suggested that when selecting gearbox lubricants, the load nature, size, gear material and operating speed of the gearbox should be considered. The heavy gear transmission has high viscosity and good lubricity. The open gear transmission with strong abrasion resistance is good in corrosion resistance, oxidation resistance and abrasion resistance. The grease with strong adhesion can be selected. Worm transmission is not conducive to the formation of oil film. , Therefore, you can choose greases containing both extreme pressure additives and oil additives, and low-viscosity greases for light-load, high-speed, and intermittently working transmission parts.
