For traditional screw transmission with long stroke length, the long screw is difficult to be processed, and the original space is large. Aiming at making up the defects, a novel dynamic combination screw transmission mechanism is put forward. The transmission principle, the parameter of extension ratio and meshing conditions of bracing screw and connecting screw are introduced. The carrying capacity is analyzed by simulation. The results show that number of connecting screw is key of parameter ratio and can be adjusted, and the large carrying capacity and accurate positioning meet the special requirement of big trip overloading linear drive applications.
