【摘要】：随着材料工业的发展，新型材料不断涌现，非金属齿轮的应用也越来越广泛，如汽车上的辅助传动系统、打印机、减速器、洗衣机等都使用了非金属齿轮。尼龙齿轮与钢制弧齿锥齿轮的啮合传动，是用尼龙作为大轮材料与金属小轮啮合实现传递运动和动力的传动副。但是非金属齿轮还没有统一的设计标准，所以对非金属齿轮的研究和分析具有很重要的意义。本文对尼龙齿轮和钢制弧齿锥齿轮的啮合传动展开了理论分析和试验探究。根据齿轮啮合原理和局部综合法计算出齿面方程和加工参数；根据齿面方程和加工参数，利用三维绘图软件SolidWorks及其编程接口API、数学计算软件MATLAB和VB编程软件等对轮齿进行了三维模型的建立；建立齿轮副的有限元模型，根据尼龙材料的粘弹性，结合接触分析理论对齿轮副进行接触分析，得到齿轮传动时的应力和应变值，并根据齿轮啮合的温度场理论，对尼龙和钢制弧齿锥齿轮的啮合传动进行热分析，，并得到了不同转速和载荷下齿轮温度的分布情况；最后根据计算的加工参数对弧齿锥齿轮进行切齿试验，结合滚检试验验证齿轮加工参数的正确性，为以后尼龙大轮模具的设计和批量注塑成型做好准备，并对传动噪声进行测试，对比金属齿轮传动，可以得到齿轮传动中引入尼龙齿轮后，传动噪声明显降低。
[Abstract]:With the development of material industry, new materials are emerging, and the application of non-metallic gears is becoming more and more extensive, such as auxiliary transmission system, printer, reducer, The washing machine uses non-metal gears, nylon gears and steel spiral bevel gears. Nylon is used as a large wheel material to meshing with metal wheels to transfer motion and power. However, there is no uniform design standard for non-metallic gears, so the research and analysis of non-metallic gears is of great significance. In this paper, theoretical analysis and experimental research on meshing transmission of nylon gear and steel spiral bevel gear are carried out. The tooth surface equation and machining parameters are calculated according to gear meshing principle and local synthesis method, and the tooth surface equation and machining parameters are calculated according to tooth surface equation and machining parameters. Using the 3D drawing software SolidWorks and its programming interface API, the mathematical calculation software MATLAB and VB programming software, the three-dimensional model of the gear tooth is established, and the finite element model of the gear pair is established, according to the viscoelasticity of the nylon material, the finite element model of the gear pair is established. Based on the contact analysis theory, the stress and strain values of gear transmission are obtained. According to the temperature field theory of gear meshing, the meshing transmission of nylon and steel arc bevel gear is analyzed. The distribution of gear temperature under different rotational speed and load is obtained. Finally, the tooth cutting test of arc bevel gear is carried out according to the calculated machining parameters, and the correctness of gear machining parameters is verified by the rolling test. In order to prepare for the design of nylon big wheel mould and the batch injection molding, and to test the transmission noise, compared with the metal gear transmission, the transmission noise can be obviously reduced when nylon gear is introduced into the gear transmission.
