Problems prone to worm reducers
In order to improve efficiency, worm gear reducers generally use non-ferrous metals as worm wheels and harder steel as worms. Because it is a sliding friction transmission, higher heat will be generated during operation, which makes the parts and seals of the reducer There is a difference in thermal expansion between them, which creates a gap in each mating surface, and the oil becomes thinner due to the increase in temperature, which is easy to cause leakage.
Worm gear wear
When the worm reducers is in normal operation, the worm is like a hardened "file", constantly filing the worm gear, causing wear to the worm gear.
Helical gear wear
It usually occurs on the worm reducer installed vertically, mainly related to the amount of lubricating oil added and the choice of lubricating oil. When installed vertically, it is easy to cause insufficient amount of lubricating oil. When the reducer stops running, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the proper lubrication protection, and they cannot get effective during start-up or operation. The high lubrication causes mechanical wear and even damage.
When the worm reducers fails, even if the reduction box is well sealed, the factory often finds that the gear oil in the reducer has been emulsified, and the bearing has been rusted, corroded, and damaged. This is because the gear oil It is caused by the condensation of moisture generated after the heat becomes cold.
