It usually occurs on the reducer of vertical equipment, mainly related to the amount and type of lubricating oil added. When using vertical equipment, it is easy to form a lack of lubricating oil. When the gearbox is intermittently operated, the transmission gear oil between the motor and gearbox is lost, and the gears do not receive the necessary lubrication protection. When the hard tooth reducer is started, the gears may experience mechanical wear and even damage due to lack of effective lubrication.
Ensure equipment quality
Special items can be purchased or configured. When disassembling and equipping gear reducer components, try to avoid using hammers or other objects to strike them as much as possible; When replacing gears, worm gears, and worms, try to use original parts and replace them in pairs as much as possible; When outputting the equipment shaft, attention should be paid to public service cooperation; To protect the hollow shaft with anti adhesive or red lead oil, it is necessary to prevent wear, rust, or scale on the joint surface, which is difficult to disassemble during repair.
Selection of lubricating oil
Helical gear worm gear reducers generally use 220 # gear oil. For reducers with heavy loads, repeated starts, and poor operating environments, some lubricating oil additives can be selected to ensure that the gear oil still adheres to the gear surface during intermittent operation, forming a protective film to prevent direct contact between metals during heavy loads, low speeds, high torques, and startup. The additive contains sealing ring regulators and anti leakage agents, which keep the sealing ring soft and elastic, effectively reducing lubricating oil leakage.
Worm bearing damaged
When problems occur, even if the gearbox seal is excellent, it is often found that the gear oil inside the gearbox is emulsified, and the bearings are rusted, corroded, and damaged. This is because after the gearbox has been operating for a period of time, the temperature of the gear oil rises and then cools down, resulting in a mixture of condensed water and water. Of course, it is also closely related to the quality of bearings and equipment technology.
