Estimation of lubricating ability of oils of transmissions of mining machines

Article preview

Lubricating value shows loading capacity of transmission oil. Poor lubricating value of friction couples which are used at borderline lubrication ordinary have wear-out areas and these friction couples also fiercely attacked by corrosion. That’s why a decision of choosing oil type have to be substantiated. In this article rapid method of lubricating capacity tests is offered.

Pilot diagnostics of mining machines transmissions state by parameters of electric drive supply

Article preview

For diagnosing transmission of the mountain machine without installation of expensive gauges pilot diagnostics on parameters of a feed of the electric motor, based on the assumption can be used, that the majority of the indignations arising in transmission and influencing at the moment of resistance, overcome by the engine, affects change of instant power consumed by the electric motor.

The area of existence of involute gear mesh with a given overlap coefficient

Article preview

It is shown, that application of the combined displacement while designing toothed gearings considerably allows to expand area of existence of gearing with a non-standard radial backlash. Influence of parameters of the tool on area of existence of gearing is submitted, the technology of realization of tangential displacement by generation of gears is described.

Features of gear design with combined displacement

Article preview

Application of the combined displacement when designing gears allows to considerably expand the area of existence of meshing with non-standard radial clearance. The influence of the parameters of the rack-shaped producing contour on the region of the meshing existence is shown, the technology of the tangential displacement realization during gear cutting is described.
