建立了蜗杆副在常规的润滑与磨损传动条件下，齿面接触线载荷的计算模型．结合蜗杆副传动的润滑与磨损规律特点，阐明了蜗杆副传动中，弹性流体动力润滑油膜和齿面磨损状态对齿面接触线载荷变化规律的影响．
The calculation model of the contact line load of the worm gear under the condition of conventional lubrication and wear transmission was established. Combined with the lubricating and wear characteristics of the worm gear transmission, the influence of elastic fluid dynamic lubricating film and tooth surface wear on the contact line load variation of the tooth surface is illustrated.
