摘　　要：以单级直齿圆柱齿轮传动为研究对象,建立了系统的数学模型.通过齿轮系统振动运动分析,论证了考虑系统振动时存在于啮合轮齿齿面间的相对滑动运动,在此基础上对比分析了考虑和不考虑系统振动时存在于啮合轮齿齿面间的相对滑动运动的特点.指出由于系统振动的原因,齿轮副的实际中心线不是固定不变的,而是以平面运动方式变化的,实际啮合点的轨迹(亦即啮合线)不是一条直线,而是一条曲线.当齿面磨损或胶合破坏始于齿高中部时,造成这种破坏的主要原因是齿轮系统的共振.A mathematic is built up for the system of singlestage transmission with cylindrical straight gears. By means of vibration analysis of the gear system, the relative sliding motion between meshed gears is discussed with consideration of system vibration and its feature is, then, analyzed by comparing it to that without system vibration. It is pointed out that, due to the system vibration, the actual center line of gear pair is not stationary but, instead, varies in the form of plane movement, making the locus (viz engaged line) of actual meshing point curved in stead of straight. When the wear or adhesive defect starts at the middle of gear height, its cause of formation is mainly the resonance of gear system.
