ANALY SIS INTO THE INFLUENCE OF SELECTED TOOT HED GEAR PARAMETERS ON THE VALUE OF SLIPPAGE AND CONTA CT STRESSES IN A CYLINDRICAL GEARBOX

摘要

The paper presents issues concerning the geometrical and durability calculations of power shift gearboxes with multi-criterion optimization, using proprietary computer software. Among many parameters influencing the value of slippage and contact stresses, the flank ratio at P-0 correction and P correction, the value of the flank angle, and the module value were analysed. The slippage was analysed at Point B1, which belongs to the beginning of the single tooth engagement area, as well as in Point B2, where the single tooth engagement area ends. Contact stresses were calculated at Point C, which is the pitch point. Their values were referenced to experimentally determined fatigue contact durability σ_(Hlim).
