摘　　要：为了提高转鼓式无链供弹系统传动稳定性,减小振动,降低故障率,本文设计了一种基于精确点建模方法下的集弹盘面齿轮,并对面齿轮不同模数、不同压力角对传动系统振动特性的影响进行了分析。首先根据面齿轮齿面方程,通过Z向截面放样法,运用Matlab和UG进行正交直齿面齿轮精确点建模。在ADAMS中根据集弹盘面齿轮在转鼓式供弹系统中的传动方式对不同模数、不同压力角的面齿轮进行了运动学振动特性分析。结果表明:在一定范围内,面齿轮模数越大,振动越小;压力角为23°时振动最大。In order to improve the transmission stability of the drum-type chain-less bomb supply system,reduce vibration and the rate of bomb jams,this paper designed a bomb-collecting disk gear based on precise point modeling,and integrates different moduli and different pressure angles.The impact of the disk surface gear on the vibration characteristics of the transmission system was analyzed.According to the face gear tooth surface equation,through the Z-direction section lofting method,Matlab and UG were used to carry out the accurate point modeling of the orthogonal straight tooth surface gear.Then,in ADAMS,the kinematics simulation of the face gears with different modulus and different pressure angles was carried out according to the movement mode of the collecting disk face gear in the drum feeding system.The results found that:the greater the face gear modulus in the proper range,the smaller the vibration;the maximum vibration is when the pressure angle is 23°.
