摘　　要： 一种新型的螺旋锥齿轮—对数螺旋锥齿轮,成功地将对数螺旋线应用为螺旋锥齿轮的齿向线,可以实现等螺旋角啮合。这种新型螺旋锥齿轮传动能够有效地解决由于螺旋角不等所带来的传动不平稳、传递效率低、磨擦磨损严重等问题。运用ANSYS软件对对数螺旋锥齿轮的装配体进行有预应力的模态分析,这种新方法要比传统的对单个齿轮进行模态分析的方法更加符合对数螺旋锥齿轮高速、重载的实际工况。通过求解该齿轮系统在两种临界状态下低阶的固有频率和主振型,进而可以确定该齿轮系统的振动频率范围,为该齿轮结构的设计避免共振提供有力的依据,同时也为该齿轮的其他动力学分析、优化设计奠定了基础。 A new type of bevel gears—logarithm spiral bevel gear,successfully makes the logarithmic spiral applied to the tooth to the line of logarithm spiral bevel gear,which can achieve helix angle of engagement.This new type of spiral bevel gear drive can effectively solve the problems of drive of not being smooth,the low transmission efficiency,the serious friction wear due to the unequal spiral angle.The prestressed modal analysis of spiral bevel gear assembly is carried on by using ANSYS software,and the new method is more in line with the actual working condition of the logarithm of spiral bevel gears—high-speed,heavy duty than traditional linear modal analysis of a single gear.By solving the gear system in two critical state of low order natural frequency and the main vibration mode,in turn,it can determine the frequency range of the gear system,which can provide a strong basis for the gear structural design to avoid resonance,and also can lay the foundation for other dynamics study of the gear,and optimize the design of the gear.
