摘　　要：针对某型火炮高低机蜗轮蜗杆因磨损产生不自锁的现状,通过分析蜗轮表面磨损形貌,采用Archard磨损理论,根据蜗轮蜗杆传动的实际情况,推导出磨损计算公式并结合有限元方法,对蜗轮的磨损寿命进行计算,为预测火炮故障和实现精确化保障打下基础.In view of the un-self-locking condition of worm gear of elevating mechanism because of wear,the surface pattern of worn worm gear is analyzed.Based on practical situation of worm gear,the Archard wearing theory is used to derive wearing life calculation equation.The FEM is also used for calculating the wearing life of worm gear.The result provides the basis for forecasting the fault of guns.
