METHOD OF INCREASING ENERGY EFFICIENCY OF MECHANICAL TRANSMISSION DUE TO OPTIMISATION OF LOADING MODE THEREOF Russian patent published in 2016 - IPC G01L3/00 

FIELD: test equipment.

SUBSTANCE: invention relates to tests and can be used to increase energy efficiency of mechanical transmission due to optimisation of its loading mode. Efficiency of mechanical transmission η is subject to hyperbolic dependence in function of moment M on drive shaft. Said dependence can determine limit value of load mode, in which efficiency of power transmission is stable at level of high values. Taking a confidence interval calculation of limit value of mechanical transmission efficiency equal to 90 %, a threshold value of efficiency η_GR, equal to 0.9 η_Σ. Then based on said hyperbolic dependence unknown threshold load moment M_GR on drive shaft of mechanical transmission becomes equal to: M_GR=10M_XΣ. Thus, based on experimental determination of total moment of idle run M_XΣ on drive shaft mechanical transmission set value of minimum required load mode, equal to M_GY, while ensuring efficiency of mechanical transmission. Method then includes calculating minimum required power of drive motor N_DB:N_DV = M_GR·ω, where ω - set frequency of rotation of drive shaft of mechanical transmission.

EFFECT: technical result consists in simplification of measurement process, broader functional capabilities.
