Ways to raise service life of open tooth gearings on an example of a drive of a spherical mill are considered. Results of introduction of automatic system of greasing are resulted and increase ways efficiency of its uses are offered.
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.
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.
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.
Advanced diagnostic and monitoring devices are required to carry out timely maintenance and repair of mining equipment and to reduce the number of emergency shutdowns. The article presents a comparative analysis of vibration and acoustic emission diagnostic techniques.
Increase of tooth gearing resource of transmissions of mining machines by energy losses minimization in gearing. Choice of rational greasing parameters of transmissions reducers. Choosing rational relations between temperature and lubricant viscosities.
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.
