Algorithm for Obtaining Balanced Specific Sliding Coefficients at the Points Where the Meshing Stars and Ends for External Spur Gears

The paper investigates the numerical possibility of obtaining equalized specific sliding coefficients for external involute spur gears based on new kinematical method that was developed in the general case of spatial gears and was customized for planar gears. The specific sliding coefficients at the points where the meshing begins (A) and ends (E) are evaluated to check if equalization is possible, then a proper numerical method is chosen and an algorithm is conceived to obtain the geometrical dimensions of the gears with optimized meshing characteristics by balanced sliding coefficients to provide longer lifetime.
