摘　　要：为了获得在不同情况下的不同工作速度,并且所需要输出的速度能够在一定的范围内均匀变化,使得速度和功率输出达到更好的平衡点,从而降低能耗,就需要使用无级变速器。目前市面上多数无级传动装置所能实现的变速范围较小,在需要进行大跨度传动的场合显得力不从心。研究了一种高效率大跨度传动的无级变速器,即一种双联变径带轮与行星传动复合无级变速器。对该新型变速器的转矩和转速进行公式推导,得出输出转速连续变化范围的最大跨度比,并对该新型变速器功率传递路径进行分析,得到一种高效的功率传递路径。该变速器具有传动功率大、传动效率高、传动比跨度范围广等特点。In order to obtain different working speeds under different conditions,the required output speed can change evenly within a certain range,so that the speed and power output can reach a better balance point,so as to reduce energy consumption.At this time,it is necessary to use continuously variable transmission(CVT).At present,most CVT devices on the market can achieve a small speed range,which is insufficient in the case of large-span transmission.A high-efficiency long-span continuously variable transmission is studied,a long-span transmission ratio cone disc composite continuously variable transmission is proposed,the torque and speed formula of this new type of transmission are deduced,and the maximum span ratio of the continuous varia⁃tion range of output speed is obtained.The power transmission path of this new transmission is analyzed,and an efficient power transmission path is obtained.The transmission has the characteristics of high transmission pow⁃er,high transmission efficiency and wide transmission ratio span.
