Common Ways for Speed Reducer to Treat Oil Leakage

Common Ways for Speed Reducer to Treat Oil Leakage:
I. Reparation: Take some as examples, scrape it if the joint surface of Worm Speed Reducer case cover is not closely sealed. Repair the tubing flare when oil leakage occurs at the tubing connection due to unfit bell mouth. Sometimes burrs, scratches and deformations of hydraulic lubricating control system components can cause external or internal oil leakage. If not serious, it can be eliminated by reparation.
II. Fastening: Fasten the screws, nuts, connection points, etc. at the leaking place to eliminate the leaking phenomenon caused by loose connection. During the process, examination should be implemented on fastening situations of all connection. For daily maintenance, operators must also be aware of this point. They are supposed to fasten immediately once loose parts are discovered so that oil leakage or other unexpected problems and accidents will be avoided.
III. Replacement: Replace them when it is found that oil leakage in speed reducer is caused abrasion on seal elements and unreparable damage on relative components. And remember to match the replacements and the opposite parts properly so as to prevent new oil leakage problem from following the old.
IV. Dredging: It is a vital oil leakage management measure to ensure a smooth return oil passage. Enlarge the oil hole promptly, remove the sewage, do dredging or add new return oil hole tubing when it is found that the holes are not large enough, structure not reasonable and tubing blocked by sewage. A smooth oil passage will greatly reduce the chance of lubricating oil leakage.
（ V. Sealing coating: As for pipe joint, use sealing adhesive to seal at the box seam to eliminate seep. Sealing coating method has the advantages of simplicity, remarkable effects, cheap costs and extensive adaptability. Usually, 70%-80% of equipment can be coped by different sealing coatings when it is leaking oil.
VI. Retrofitting: Somtimes it is necessary to improve sealing materials, change fastening methods, replace lubricating agent, adjust return oil position, modify pre-leakage measures, etc in order to resolve the leakage problem. Retrofitting can take many forms. Generally speaking, it should be remembered not to affect the normal operation nor the original strength and rigidity of machine, especially by adding return chutes, enlarging screw holes, attaching oil dripping pans, etc.
VII: Adjustment: Reduce system pressure, adjust sliding bearing, narrow the gap between shaft hole and journal by adjusting the oil pressure of hydraulic lubricating system so as to avoid leakage caused by too much overflow. Overcome the leakage problem resulted from its failure by means of adjusting oil scraper like loosening, tightening, raising and lowering the felt. What is more, it is the best to adjust at first and then take some other measures based on the proper matching of relative components.
