Gear reducer Reasons for oil leak

Once the Hypoid Reducer oil spills, not only a waste of resources and pollute the environment, can cause serious gear reducer less oil off the oil, the gear meshing surface wear and tear, bite and then welding or peeling occurs, resulting in equipment accident. Here to talk about common and everyone gear reducer is what causes leakage.
1 gear reducer generating a pressure difference inside and outside
Gear reducer operation, the movement, the friction heat and affected by the ambient temperature, the gear reducer temperature, if no holes or holes to plug, then gradually increase the pressure inside the machine, the higher the internal temperature with the outside world The greater the pressure difference, the lubricant under pressure effect, leaking from the crevice.
2 gear reducer unreasonable structure design
(1) hole cover is too thin, easily deformed after tightening the bolts, the bonding surface uneven, the oil spill from the contact gap.
(2) in the manufacturing process of the gear reducer, casting annealing or aging treatment is not carried out, not eliminate stress, the inevitable deformation, resulting in the gap, resulting in leaks.
(3) did not return to the housing sump, lubricating oil accumulated in the shaft seal, cover, joint surface, etc., under the pressure differential, leakage outward from the gap.
(4) The seal structure design is unreasonable. Early use of gear oil groove, the felt ring type seal structure, so that when the assembly is compressed felt deformed, while the combination of surface cracks sealed. If the spigot in contact with the seal is not very satisfactory, since the compensation performance felt very poor, sealed in a short time lapse. Although the oil groove back hole, but easily blocked, back to the oil effect is difficult to play.
3 excessive amount of fuel
Gear reducer during operation, the oil tank is agitated badly, lubricating oil splashing around in the machine, if an excessive amount of fuel, lubricating oil accumulate in large numbers of seals, the joint surface, etc., resulting in leaks.
4 improper maintenance process at the time of equipment maintenance, due to the combination of surface dirt removal is not complete, or the improper selection of sealants, seals direction anti-loaded, no timely replacement of seals, etc. can also cause oil spills. These are universal finishing gear reducer oil spills cause analysis, in addition in addition to the above reasons, the gear reducer oil spill may also seal quality and assembly process, shaft surface roughness higher aspect, and if found during the operation gear machine oil spills, please calm analysis, properly handle!
