Influnce of worm gear lubricant on efficiency
This work presents a theoretical approach to calculation of the maximum load and the power loss in worm gears based on Hertz's theory of contact pressures. As a result an expression for the efficiency of toothing is obtained. After that a computer program for determining the contact lines in the gear engagement field, required for calculation of toothing efficiency of the worm gears is developed. This program enables calculations of non-dimensional quantities, which depend on the toothing geometry only (and not on the operating conditions), and the parameters necessary for the calculation of the friction factor. The efficiency based on theoretical considerations is compared to experimental results obtained on a test bench with real worm gears for two rotational speeds at the inlet and for different loading conditions at the outlet. In doing that, two kinds of oil, mineral and synthetic are employed.
