Working heat is taken away, and avoids because sliding oil heating causes lubricating oil to fail in decelerator, so that bearing friction increases, tooth surface abrasion adds
Weight, and appearance phenomena such as tooth face agglutination, and then decelerator service life is shortened.
The technical solution of the present invention four is：Blow vent is designed, and blow vent, and profit are designed with reducer shell
Decelerator stomata is connected with high-pressure gas circuit with air pressure balance pipeline, with the pressure inside balanced reducer, and is covered with therebetween
GORE-TEX films, and there is oil cleaner screen to filter out the oil being mingled with gas in the Front-end Design of the film.The solution principle of the present invention is such as
Under：Because the high speed rotation of the parts such as decelerator internal gear pair, bearing can produce substantial amounts of working heat so that oil temperature liter
Height, and lubricating oil steam is produced, and then cause the thermal expansion of decelerator inner air, pressure rise.And the design of passage can be with
While making to keep suitable pressure in oil sump, and also act as holding oil pump performance, the trouble free service inlet-pressure of oil pump is kept
Power, while also assures that the normal oil return of decelerator lubricating oil.And GORE-TEX films can effectively prevent that lubricating oil from revealing, have simultaneously
Stronger gas permeability.
The technical solution of the present invention five is：Oil cooler is designed, and fluid channel heat exchange is provided with lubricating oil device
