摘要
针对直齿圆柱齿轮动态转速及啮合力难以实际测量及试验成本较高等问题,以某直齿圆柱齿轮传动系统为研究对象,运用三维建模软件建立齿轮传动系统装配模型,导入动力学仿真软件ADAMS中建立其动力学仿真模型,对其转速及动态啮合力进行仿真分析。仿真结果表明:平稳的加载有利于齿轮传动系统的动力及运动的传递;齿轮转速及动态啮合力都呈现周期性的波动,与理论计算值基本接近;不同频率下齿轮啮合力幅值不同;齿轮传动系统其他零部件设计应尽量避开动态啮合力幅值较大时的频率,防止齿轮系统产生共振。该研究为直齿圆柱齿轮传动性能改善、振动噪声的减小、啮合特性的优化提供理论依据。
Aiming at the problems of the dynamic speed and meshing force of the spur gear were difficult to measure and the test cost was high, a spur gear transmission system has been taken as the research object, and the 3D modeling software has been used to build the gear drive system assembly model into the dynamic simulation software ADAMS to establish the dynamic simulation model;the rotational speed and dynamic meshing force have been simulated and analyzed. The simulation results show that the steady loading is beneficial to the transmission of power and motion of the gear transmission system. The gear rotation speed and dynamic meshing force are cyclical fluctuations and the theoretical calculations value are basically the same. The gear meshing force amplitude is different at different frequencies. When designing other parts of the gear transmission system,it should avoid the frequency of the dynamic meshing force amplitude is large, so as to prevent the resonance of gear system. The research provides a theoretical basis for the spur gear transmission performance improvement , the vibration noise reduction and the meshing characteristics optimization.
