在风力发电机中,转子的低转速是通过增速器增速后传给发电机的。平行轴齿轮传动机构的体积庞大且笨重。美国研制了一种新型行星齿轮增速器,已投入使用。它比普通平行轴齿轮传动有如下优点:结构简单而紧凑,重量轻,因同轴传动,受安装偏移影响小;旋转部分质量轻且惯性力小。新型行星齿轮增速器为三级传动(见图1)。第一级为固定的齿圈,行星载臂由风车转子推动旋转。第二级和第三级的行星载臂是固定的,齿圈由前一级太
In wind turbines, the low rotor speed is transmitted to the generator via the speed increaser. Parallel shaft gear drives are bulky and bulky. The United States has developed a new planetary gear speed increaser, has been put into use. Compared with ordinary parallel shaft gear drive, it has the following advantages: simple and compact structure, light weight, small impact due to installation offset due to coaxial drive, light rotation part and small inertial force. The new planetary gear speed increaser for the three transmission (see Figure 1). The first stage is a fixed ring gear, planetary carrier arm driven by the windmill rotation. The second and third stage planet carrier arm is fixed, the ring gear from the previous level too
