摘　　要：为了提高微线段齿轮的应用性,从中心距偏差的角度对微线段齿轮的动力学特性进行了研究。依据微线段齿轮齿廓构型原理,基于齿轮啮合关系推导了其齿廓数学模型;采用离散化TCA(齿面接触分析)方法计算了微线段齿轮的传动误差,分析了不同中心距偏差对渐开线和微线段齿轮的传动误差和侧隙的影响;通过建立微线段齿轮动力学模型,分析了渐开线和微线段齿轮在不同载荷、转速下中心距偏差对动态响应的影响。结果表明:微线段齿轮比渐开线齿轮对中心距偏差更为敏感;在低速轻载工况下,渐开线齿轮的动力学特性更好,在载荷较大的工况下,尤其是在中高速重载工况下,当中心距偏差被控制在一定范围内时,微线段齿轮具有更好的动态特性。According to the forming principle of micro-segment gear profile,the mathematical model of its tooth profile was established.The transmission error of the micro-segment gear was studied by the discrete TCA(tooth contact analysis)and the influence of different deviations on the transmission error and meshing backlash of the involute and micro-segment gear was analyzed comparatively.Through the establishment of micro-segment gear dynamics model,the influence of center distance deviation on dynamic response of involute and micro-segment gear under different loads and speeds was analyzed comparatively,and the result indicates that micro segment gear is more sensitive to center distance deviation than involute gear.Under the condition of low speed and light load,the dynamic characteristics of involute gear are better.But,under the condition of large load,especially under the condition of medium and high speed and heavy load,the micro segment gear has better dynamic characteristics when the center distance deviation is controlled within a certain range.
