Приведены экспериментальные доказательства повышения контактных давлений, при которых достигается минимальное значение коэффициента трения, при введении в смазочное масло стандартной противоизносной присадки - диалкилдитиофосфата цинка (ZDDP). Предложена реологическая модель, позволяющая рассчитывать влияние противоизносных присадок на величину гидродинамических давлений в смазочном слое подшипников тепловых двигателей.
