齿轮减速机传动效率高，耗能低，性能优越。摆线针轮减速机是一种采用摆线针齿啮合行星传动原理的传动机型，是一种理想的传动装置，具有许多优点，用途广泛，并可正反运转。
Gear reducer has high tran***ission efficiency, low energy c***umption and superior performance. Cycloidal pinwheel reducer is a tran***ission type which adopts cycloid needle tooth meshing planetary tran***ission principle, and it is an ideal driving device. It has many advantages, widely used, and can run in reverse direction.
降低减速机运转时的齿轮传动噪声已成为行业内的重要研究课题，国内外不少学者都把齿轮传动中轮齿啮合刚度的变化看成是齿轮动载、振动和噪声的主要因素。减速器是一种由封闭在刚性壳体内的齿轮传动、蜗杆传动、齿轮-蜗杆传动所组成的***部件，常用作原动件与工作机之间的减速传动装置。用修形的方法，使其动载荷及速度波动减至小，以达到降低噪声的目的。这种方法在实践中证明是一种较有效的方法。
Reducing the gear tran***ission noise of the reducer has become research topic in the industry. Many scholars both at home and abroad regard the change of gear tooth meshing stiffness as the main factor of gear dynamic load, vibration and noise. The method of modification is used to minimize the dynamic load and speed fluctuation in order to reduce noise. This method is proved to be a more effective method in practice.
减速机内部齿轮齿形修整（修缘和修根）和齿顶倒角 将齿顶的齿形切削成比正确的渐开曲线略呈凸形。当齿轮齿面受外力产生变形时，可以避免对与之啮合的齿轮产生干涉，并且可以降低噪音，延长齿轮寿命。
The internal gear of the reducer is trimmed (trim and trim) and tooth top chamfering to make the tooth shape of the tooth top convex than the correct involute curve. When the gear tooth surface is deformed by external force, it can ***oid interference to the gears engaged with it, and can reduce noise and prolong the service life of gears.
