某型航炮拨弹轮强度分析

Analysis of an Aircraft Gun Feed Sprocket Strength

针对某航炮拨弹轮易发生故障的问题,根据航炮机构动力学原理,建立了进弹机构子系统的运动微分方程,计算了进弹阻力,对拨弹齿的受力情况和强度进行了分析和校核,并为如何使用和维护提供了建议。

To solve the problem that aircraft gun feed sprockets are liable to break in application,accord- ing to principle of mechanismic dynamics,differential equations of mechanism are found.The conclusion that its strength can meet requirement is obtained by calculating feed resistance and analysizing force to claw tooth.Consequently some suggestions about using and maintaining the gun are put forward.
