(1) almost gear tooth profile little radius of curve, the universal terms for 10s of mms, the constitution of the oil wedge;
(2) gear adjoin force is really high up;
(3) between the teeth while the revolving and sliding, and the sliding instruction and velocity of drastic alters;
reconditioned gearboxes (IV) lubrication is periodic, all bite jointly are asked to restore the film;
(5) the servo planetary gear reduce material, heat handling, machining and gathering circumstances likewise make an affect by the posit of lubrication
Secondly, the open gear lubrication:
Open gear easily to fall under the dot, debris and different outside media made by oil contamination, gear easy to abrasive wear. When the split gear to contain cover dot below the equal acting circumstances, open gear lubrication demands and enclosed gear. Open up gear drives usually apply a high-viscosity oil, a lubricant or grease of the asphaltenes, and could be more efficient at a comparatively low speed.
Gear oil execution demands
A appropriate viscousness
Fine thermal and oxidative stableness
3 fine abrasion resistance, the resistance burden operation
Fine anti-foam
Five fine rust and corrosion resistance
Fine Demulsibility variable speed gearbox
