摘　　要：在分析国家机械行业标准的JB/T6950-93——行星锥盘无级变速器的结构和传动基础上,对其结构进行创新设计,将加压弹簧施压在恒轮上,并采用蜗轮蜗杆机构和丝杆螺母传动的组合机构实现调速控制,可以多方面改善此类无级变速器的性能。The planetary bevel-type CVT is described in the national m echanical industrial standard JB/T6950-93.Based on the analysis of this structure and working principle,a innovation structure type is designed and man ufacture.That is brought the spring force to bear on the stator plate,adopted t he combined mechanism with worm-wormwheel and feed screw nut drive to bring the speed setting control about.By use,the performance of this CVT is improved in many ways,and the character of constant power is also too.
