Gear (Non-standard gear custom) lubricating characteristics
First, enclosed gear lubrication:
1, the majority of small radius of curvature of the tooth profile gear, usually tens of millimeters, the formation of an oil wedge poor;
2, the contact pressure is very high gear;
3, between the tooth surface while a rolling and sliding, and dramatic changes in the direction and speed of the slide;
4, lubrication is intermittent in nature, every bite together need to re-establish the film;
5, the gear material, heat treatment, machining and assembly of lubrication conditions also have an impact
Second, the open gear lubrication:
Open gear easily fall into the dust, debris and other external media caused by oil pollution, easy to produce abrasive wear gear. After taking off the gear block dust cover, under the same operating conditions, lubrication requirements for open gears and enclosed gear same. Open gear drives typically use high viscosity oil, asphaltene lubricants or grease, and at a relatively low speed can be more effective work.
Gear oil performance requirements:
1, a suitable viscosity
2, good thermal oxidation stability
3, good abrasion resistance, load performance
4, good anti-foam
5. Good rust and corrosion resistance
6, good resistance to emulsification
7, good shear
