Fault analysis of helical gear reducer!

How should we solve the failure of the helical gear reducer.The main purpose of summarizing the problem is to better understand the fault and propose a corresponding solution.
1. Helical gear reducer heating and oil leakage filter
In order to improve efficiency, worm gear reducers usually use non-ferrous metals as worm gears, and worms use more resistant steel.Due to the sliding friction transmission, more heat will be generated during operation, resulting in differences in thermal expansion between components and seals, resulting in gaps on each mating surface.As the temperature increases, the lubricating oil becomes thinner, which is easy to cause leakage.There are four main reasons for this situation: first, the combination of materials is unreasonable; second, the surface quality of the meshing friction surface is poor; third, the amount of lubricating oil added is incorrect; fourth, the assembly quality and use environment are poor.
2, small helical gear wear fault helical gear reducer
Most of the faults are that in the design of some reducers, the oil lubrication is not fully considered, that is, when the oil is less, the gears cannot be fully lubricated, which will lead to accelerated gear wear.Some vertical mounting methods have more of these failures.In a vertical installation environment, when it stops running, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the proper lubrication protection.
3. The sealed helical gear reducer will also find problems such as internal bearing corrosion
Sealed reducers will also find issues such as internal bearing corrosion.This is usually because after a period of operation, the condensate produced after the gear oil temperature rises rises and mixes with water.When this happens, gear oil emulsification, bearing damage, corrosion, etc. can often be seen.
4. Abnormal operation of the helical gear reducer, causing great noise and failure
There are two cases here.One is knocking noises, such as noticeable irregular meshing.Two, spinning/grinding noise.These two different noises are usually caused by different defects.The latter is mostly the damage done.The former condition may be worn gears.
