Inserted gear lubrication features:
(A) almost the gear tooth profile minor radius of curve, the universal circumstances for tens of millimetres, the shaping of the oil wedge;
(B) gear adjoin pressing is very high up;
(C) between the teeth whilst the roll and slipping, and the slipping way and velocity of forceful alters;
(D) lubrication is periodic, all bit jointly are needed to restore the film;
(E) the gear stuff, heating handling, machining and gathering circumstances as well have an affect of the state of lubrication
Secondly, the open gear lubrication:
Open gear easygoing to fall under the dot, dust and other outside media made by oil contamination, gear easily to abrasive wear. When the split gear to bring cover up Dust below the same cultivating circumstances, open gear lubrication demands and inserted gear. Open gear drives commonly apply a high-viscosity oil, a lubricator or grease of the asphaltenes, and could be more efficient at a comparatively low speed.
A suited viscosity
Fine thermal and oxidative stableness
3 good abrasion opposition, the resistance load execution
Fine anti-foam
5 fine rusting and erosion opposition
Good Demulsibility variable speed gearbox
