Design and control strategy of intelligent lubrication system for mine hoist head sheave
Meitan xuebaoThe sheave is an important part of a mine hoisting system. Once it fails, it will not only affect the production efficiency of coal mine, but also cause some safety risks. Poor lubrication is one of the main causes of sheave failure.

GEARBOX LUBRICATION SYSTEM OPTIMIZATION
Acta Mechatronica, 2021 The aim of gearbox lubrication is to reduce wear on the sides of the teeth, increase of the efficiency by reducing friction as well as dissipating the heat generated by friction. Lubrication of gearboxes is a discontinuous process, that means, during the meshing every meshed pair of teeth needs to have a new lubrication film created on the surfaces ...
