【摘要】：弧齿锥齿轮由于其重合度大、传动平稳、承载能力高等特点,在交通、航空航天、航海、机床等现代机械传动中得到了广泛的应用。而行星齿轮传动以其承载能力高、重量轻、体积小、传动比大等优点近年来在工程机械领域得到了快速发展,在现代动力机械中几乎具有不可替代的作用。本文结合弧齿锥齿轮的特点及行星齿轮传动的原理,提出了一种新型弧齿锥齿轮行星传动,并进行了较深入的理论探讨与试验研究。本文综合弧齿锥齿轮的啮合特性和行星传动的原理分析了弧齿锥齿轮行星传动的原理和实现方法。推导了弧齿锥齿轮行星传动的传动比和传动效率的计算公式,并结合实例进行了分析。对弧齿锥齿轮行星传动的啮合性能进行了分析。利用弧齿锥齿轮设计及分析软件对弧齿锥齿轮的接触区和传动误差进行了分析和预置设计;运用齿轮动力学理论,建立了弧齿锥齿轮行星传动的动力学模型,利用Runge-Kutta方法对其进行了求解分析。借鉴传统圆柱齿轮行星传动的结构,根据弧齿锥齿轮的传动特点及几何特征,设计了非正交传动比21.5、模数5mm的弧齿锥齿轮行星传动齿轮箱。完成了齿轮箱的制造、安装和调试。进行了弧齿锥齿轮行星传动齿轮箱的运转噪音和传动效率的测试试验。经实验验证,齿轮箱测试系统运转综合噪声在90dB以下,传动效率不同的工况条件差别较大,其中较理想的情况下可达到57.3%。验证了本文所提出的新型弧齿锥齿轮行星传动的可行性,达到了预期目的。
[Abstract]:Spiral bevel gear due to the coincidence degree, smooth transmission, bearing characteristics, higher ability in transportation, aerospace, navigation, machine tools and other modern mechanical transmission has been widely used. The planetary gear transmission with its high bearing capacity, light weight, small volume, high transmission ratio and other advantages in recent years in Mechanical Engineering the field has been developing rapidly, almost play an irreplaceable role in modern power machinery. Based on the principle and characteristics of planetary gear transmission spiral bevel gear, put forward a new kind of spiral bevel gear planetary transmission, and discusses the theory and experimental research deeply.
The character of this comprehensive meshing principle of spiral bevel gear and planetary gear analysis principle and implementation method of the spiral bevel gear planetary transmission. The formula of the spiral bevel gear planetary transmission ratio and transmission efficiency, and combined with case analysis. The meshing performance of spiral bevel gear planetary transmission are analyzed. Using spiral bevel gear design and analysis software of the contact area of the spiral bevel gear and transmission error are analyzed and the use of preset design; gear dynamics theory, a dynamic model of a spiral bevel gear planetary transmission, has carried on the analysis using the Runge-Kutta method. From the structure of the traditional cylindrical gear planetary according to the characteristics of transmission, transmission and geometric characteristics of the spiral bevel gear, the design of non orthogonal transmission ratio 21.5, spiral bevel gear planetary gear box module 5mm. The gear box The test of the operation noise and transmission efficiency of the spiral bevel gear planetary gear box is carried out.
After experimental verification, the gear box test system integrated operation noise below 90dB, the transmission efficiency of different working conditions are different, the ideal circumstances can reach 57.3%. to verify the feasibility of the new spiral bevel gear planetary transmission is proposed in this paper, to achieve the desired purpose.
