    摘要:

    三环减速器是我国独创的一种新型传动装置,利用三相并列双曲柄机构克服死点,以传动比为49.5的SHQ50三环减速器为研究对象,分析了其基本机构特点和传动机理。利用声强法对其表面噪声分布进行了详细的试验分析,给出了该机输入和输出侧面及顶面的三维声强分布图和等值线图。结合测点频谱图,得出其噪声评价指标及产生噪声的原因和机理,为正确设计三环减速器,减少其振动和噪声提供理论依据。

    Abstract:

    The three ring reducer is a kind of gear drive developed in the past decade. Adopting the new conception of "parallel and movable axis" of multiple mechanisms, this kind of gear drive has many characteristics such as large transmission ratio, high efficiency and so on. As the three ring reducer has been invented only for ten years, up to date the design of the gear drive is only made with analogue method, no design theory can be followed, there exist serious vibration and noise in transmission, which limit its wide application in industry. In this paper, the transmission principle of SHQ50 reducer is studied, the surface noise distribution of the reducer, transmission ratio 49.5 , is measured and analyzed by means of sound intensity method. The 3D distribution maps of noise on top of reducer, input side and output side of reducer, and left side and right side of reducer are drawn. With the sound intensity frequency maps of each measuring point, the sources of giving out noise are analyzed. The reducer of low vibration and noise can be designed rightly according to the analysis.
