Background technique
Gear drive is one of most important kind of drive in machine driving, and gear passing movement and power are by gear
Flank of tooth intermeshing is completed, and friction is during which necessarily led to, and for the service life for keeping gear mechanism, mesh tooth face needs lubricating oil
Lubrication, lubricating oil form adsorbed film and reaction film on the flank of tooth, to reduce coefficient of friction and bear external applied load.The machine of modernization
Develop towards the direction of top load, the bearing capacity and use condition to gear propose harsher requirement.It gives full play to
The bearing capacity of gear reduces the possibility of gear failure, extends gear life, improves the transmission efficiency of gear, lubrication is very
Important link.
Base oil for deploying industrial gear oil mainly includes mineral base oil and synthetic base oil two major classes, synthesizes base
Plinth oil is expensive, is generally all deployed with mineral base oil in addition to special occasions.At present in terms of gear lubrication, mineral base
