【摘要】 针对大型齿轮不易修形的难题,笔者提出了通过对刀具进行修正,实现在加工过程中对齿轮齿廓进行展成修形的方法,并详细分析了大型齿轮的修形原理和修形刀具的设计方法。笔者采用齿轮啮合理论,推导了修形刀具加工大型齿轮的齿面方程。以?4.8 m×105 m回转窑开式大齿轮为研究对象,采用MATLAB软件对加工过程进行仿真分析,从而验证了理论分析的正确性和设计方法的合理性,为精制修形滚刀的设计提供理论支持,对改善大型齿轮的传动特性,提高承载能力和可靠性具有重要的意义。更多还原

【Abstract】 In view of the difficulty in profile modification of the large gear, the paper proposed expansion modification of tooth profile during machining process after correcting the gear cutter. In the paper, profile modification theory and process of designing the gear cutter were introduced in detail, and gear meshing theory was applied to deduce the equation of large gear machined by corrected cutter. Moreover, the open gear in ? 4.8×105 m rotary kiln was taken as the study objective, its machining process was simulated by using MATLAB, and the results indicated the correctness of the theoretical analysis and the reasonableness of the design. The study offered theoretical support for design of the finish modifying hob, and possessed significance for improving the transmission performance as well as enhancing the load-carrying performance and reliability of the large gear.更多还原
