Problems solved by technology

[0002] Reducers are widely used in various mechanical transmission systems. The following problems often exist in the assembly of oil seals in the production and maintenance of the transmission industry: On the one hand, there are no suitable oil seal installation tools at the assembly site. When the oil seal is assembled, the oil seal is tilted and the concentricity with the shaft Poor, resulting in oil leakage from the flange of the oil seal lip, the oil seal is scrapped or the best effect of oil sealing cannot be achieved; on the other hand, the parts of the oil seal set have burrs, sharp angles and other defects, which will also cause oil seal lip scratches and oil leakage
This leads to a low probability of success of the oil seal set at one time, and requires high technical proficiency of the installation workers; the efficiency of the oil seal set is low, and it usually takes 1-2 hours

Abstract

The invention provides a speed reducer oil seal safety sleeving method which mainly comprises the following steps that oil seals are pressed to be fitted on an end cover by pressing covers, thus an oil seal assembly is formed; a speed reducer output shaft is coated with a plastic membrane; lubricating grease is uniformly brushed onto the surface of the plastic membrane; the oil seal assembly sleeves the speed reducer output shaft, and the oil seal assembly is pushed and assembled in a seat hole by forward and reverse rotation and / or front and back swinging; and the plastic membrane is taken out and the oil seal assembly sleeving is completed. According to the speed reducer oil seal safety sleeving method, lips of the oil seals can be prevented from being scratched and flanged, the oil seals can be assembled in place at one time successfully, the oil seal sleeving efficiency is improved, the requirement on the technical proficiency of a mounting worker is low, used oil seal sleeving fittings are simple, and the cost is low. The speed reducer oil seal safety sleeving method can be widely applied to the transmission industry for oil seal sleeving work in production and maintenance.
