Mathematical model of energy efficiency in spur gears

The impact of geometric parameters of teeth and lubricating oils to the efficiency of utilization of involute spur gears, when the transverse contact ratio is 2 < εα ≤ 3, has been analyzed in this paper. The mathematical model and computer program for determining the current and the effective value of the efficiency of utilization have been developed. The influence of the character of load distribution and energy losses due to heating effects during the meshing period is included in the factor of load distribution. The results of computer simulation are given in the form of a diagram of the current values of the efficiency of utilization during the meshing period. Also, the values of effective efficiency of utilization for the considered cylindrical gear pairs have been calculated.
