DCY hard tooth surface reducer manufacturer

Friends who often use DCY hard tooth surface reducer know that oil leakage is inevitable during use.Oil leakage not only wastes lubricating oil,but also increases costs for oneself.This requires us to identify the cause of the oil leakage in order to quickly solve this problem.Let's follow the DCY hard tooth surface reducer manufacturer to take a look at the detailed content:

1、Pressure difference between the inside and outside of the ZQ reducer:During the operation of the ZQ reducer,the friction heating of the moving pair and the influence of the ambient temperature cause the temperature of the ZQ reducer to rise.If there are no ventilation holes or the ventilation holes are blocked,the pressure inside the machine gradually increases.The higher the temperature inside the machine,the greater the pressure difference with the outside world.Under the pressure difference,lubricating oil leaks out from the gaps;

2、The structural design of ZQ reducer is unreasonable
1.The inspection hole cover plate is too thin,which can easily cause deformation after tightening the bolts,resulting in uneven joint surfaces and oil leakage from the contact gaps;
2.During the manufacturing process of DCY hard tooth surface reducer,if the castings are not annealed or aged,and the internal stress is not eliminated,deformation will inevitably occur,resulting in gaps and leakage;
3.There is no oil return groove on the box,and lubricating oil accumulates at the shaft seal,end cover,joint surface,etc.Under the pressure difference,it leaks outward from the gap;
4.The design of the shaft seal structure is unreasonable.Early DCY hard tooth surface reducer often used oil groove and felt ring shaft seal structures.During assembly,the felt was compressed and deformed,and the joint surface gap was sealed.If the contact between the shaft neck and the seal is not ideal,due to the poor compensation performance of the felt,the seal will fail in a short time.Although there are oil return holes on the oil groove,they are easily blocked,and the oil return function is difficult to play.
3、Improper maintenance process:During equipment maintenance,incomplete removal of dirt on the joint surface,improper selection of sealant,reverse installation of sealing components,and failure to replace sealing components in a timely manner can also cause oil leakage.
4、Excessive oil filling:During the operation of the DCY hard tooth surface reducer,the oil tank is stirred vigorously,and lubricating oil splashes everywhere inside the machine.If the oil filling is too high,a large amount of lubricating oil will accumulate at the shaft seal,joint surface,etc.,leading to leakage;
In order to save the use of lubricating oil,it is necessary to promptly identify the cause of oil leakage in order to solve the problem in a timely manner.
