1 improper selection of lubricating oil reducer parts of different parts of the lubricating oil varieties, viscosity and other performance requirements are different. The choice of matching can reduce the frictional resistance between the internal contact surfaces of the lubricating oil, and the wear of the gear surface and the noise and vibration of the transmission will also be reduced. Improper selection of lubrication effect will be greatly weakened, the dynamic pressure oil film is easy to rupture, gears and other surfaces contact each other, the pressure is concentrated, serious damage to the gear surface, and even damage the equipment. 2 improper amount of lubricating oil reducer in the process of high-speed operation, the oil pool is vigorously stirred, lubricating oil inside the reducer burst everywhere. If the amount of lubricating oil is too much, a large amount of lubricating oil will accumulate in the shaft seal, end cover, joint surface, etc., resulting in oil leakage, which will increase the running resistance of rotating parts such as bearings and gears, increase the power consumption, and reduce the heat dissipation space. The oil temperature and viscosity drop make the oil film thinner, which destroys the normal lubrication state of the friction surface and causes serious equipment wear. If the amount of lubricating oil is too small, the gear, bearing and joint surface of the reducer can not get enough lubricating oil, can not form an oil film, dry friction, also make the equipment wear seriously. 3 When air, mechanical impurities and free water in the lubricating oil invade the reducer, the lubricating oil in the machine is easily affected by mechanical impurities, water, air and other pollutants. For example, free water can make the lubricating oil produce acidic substances, corrode metal parts and aggravate wear. Oil mixed with air can make the oil oxidation deterioration, and even make the metal parts oxidation corrosion, impurities to reduce the cleanliness of the lubricating oil, oil deterioration, viscosity grade decreased, resulting in speed control system jam, failure, and even equipment damage.
1 improper selection of lubricating oil
The different parts of the reducer have different requirements for the variety, viscosity and other properties of the lubricating oil. The choice of matching can reduce the frictional resistance between the internal contact surfaces of the lubricating oil, and the wear of the gear surface and the noise and vibration of the transmission will also be reduced. Improper selection of lubrication effect will be greatly weakened, the dynamic pressure oil film is easy to rupture, gears and other surfaces contact each other, the pressure is concentrated, serious damage to the gear surface, and even damage the equipment.
2 Inappropriate amount of lubricating oil
During the high-speed operation of the reducer, the oil pool is vigorously stirred, and the lubricating oil is shot everywhere inside the reducer. If the amount of lubricating oil is too much, a large amount of lubricating oil will accumulate in the shaft seal, end cover, joint surface, etc., resulting in oil leakage, which will increase the running resistance of rotating parts such as bearings and gears, increase the power consumption, and reduce the heat dissipation space. The oil temperature and viscosity drop make the oil film thinner, which destroys the normal lubrication state of the friction surface and causes serious equipment wear.
If the amount of lubricating oil is too small, the gear, bearing and joint surface of the reducer can not get enough lubricating oil, can not form an oil film, dry friction, also make the equipment wear seriously.
3 Lubricating oil in air, mechanical impurities and free water and other pollutants intrusion
During the operation of the reducer, the lubricating oil in the machine is easily affected by mechanical impurities, water, air and other pollutants. For example, free water can cause the lubricating oil to produce acidic substances, corrode metal parts, and aggravate wear. Oil mixed with air can make the oil oxidation deterioration, and even make the metal parts oxidation corrosion, impurities to reduce the cleanliness of the lubricating oil, oil deterioration, viscosity grade decreased, resulting in speed control system jam, failure, and even equipment damage.
