摩擦式行星传动无级变速器可以实现无级调速,简化传动方案。与其它型式的无级变速设备相比较,其主要优点是结构简单,维修操作方便,恒功率特性好,噪音低。其变速范围很广,理论上趋于无穷大。如果结构合理,可以从零转速起动,能适应变工况工作,在工业界受到越来越多的重视和应用。一、传动方案及结构参数分析 XZW型无级变速器传动方案如图1所示,此机构由输入轴1,输入圆盘2,行星锥轮3,调速环4,支承环5,输出圆盘6,加压盘7,加压弹簧8及输出轴9等构成。
Friction planetary transmission stepless speed variator can be realized to simplify the transmission program. Compared with other types of CVT equipment, its main advantages are simple structure, easy maintenance, constant power characteristics and low noise. Its variable speed range is wide and theoretically tends to infinity. If the structure is reasonable, you can start from zero speed, to adapt to changing conditions, in the industry by more and more attention and application. First, the transmission scheme and structural parameters analysis XZW-type CVT transmission scheme shown in Figure 1, this body consists of the input shaft 1, the input disc 2, planetary bevel gear 3, speed control loop 4, the support ring 5, the output disc 6, the pressure plate 7, the pressure spring 8 and the output shaft 9 and other components.
