Lubrication of gears and bearings

Lubricants in machines are used to reduce wear intensity, reduce friction forces, remove heat from friction surfaces, and also to protect parts from corrosion. The reduction of friction forces due to lubrication provides an increase in the efficiency of the machine, in addition, dynamic loads are reduced, smoothness and accuracy of the machine are increased. We accept liquid industrial oil I30A GOST 2079975. The depth of immersion of gears in oil must be not less than the engagement module and not more than a quarter of the pitch circle of the wheel.
