谐波传动亦称弹性变形齿轮传动,主要由波发生器,柔轮和刚轮三部分组成。工作时,由波发生器通过柔轮变形产生机械波,从而产生齿间相对位移而达到传动目的。通常波发生器为主动件,其余二个元件分别为从动件和固定件。当波发生器有两个触头时,柔轮呈椭圆形,有两个啮合区,称双波传动,当波发生器有三个触头时,柔轮呈三棱圆形,有三个啮合区,称三波传动。二齿轮完全啮合区称波峰,二轮齿完全脱离区称波底,如图1所示。谐波传动轮齿的理想齿形曲线为直
Harmonic drive, also known as elastic deformation gear drive, mainly by the wave generator, flexible wheel and just round of three components. Work, from the wave generator through the flexible wheel deformation generated mechanical waves, resulting in relative displacement between teeth to achieve the purpose of transmission. Usually the wave generator is the active part, the other two parts are the driven part and the fixed part respectively. When the wave generator has two contacts, the flexible wheel is oval, there are two meshing zone, said double wave drive, when the wave generator has three contacts, the flexure was a three-sided circular, with three meshing zone , Said three waves drive. Fully meshed two gear said peak, two teeth completely out of the area said the bottom, shown in Figure 1. Harmonic transmission gear teeth ideal profile straight
