Abstract：The transmission ratio of single-stage movable tooth transmissions was relatively low， while the series-connected movable tooth transmisson structure was lack of compactness and inability to achieve power spliting transmission.Therefore，a novel paralel compound movable tooth transmission device was proposed，which comprised of a primary planetary gear transmisson and a planar steel bal movable tooth transmisson. The operating principles and structures of this device were introduced，along with the tooth number calculation method.The profile equations of the double-circular-arc tooth profiles were derived，and the analysis of the meshing characteristics was conducted. The results show that this innovative transmission device features a compact structure，enabling a high transmission ratio.By adjusting the number of teeth，the device achieves both forward and reverse output rotation，power spliting transmission，and“concave-convex”tooth contact. It exhibits high load-bearing capacity and is suitable for applications requiring large transmission ratios and high power density.
