Abstract

The invention relates to the technical field of gear transmission, in particular to a backlash-free speed reducer with movable teeth and fixed teeth in composite transmission. An eccentric shaft section on an input shaft rotates to drive a planet disc gear to revolve around the axis of the input shaft, a transmission ball is pushed to move along a planet disc gear rail of the planet disc gear, a left end cover is fixed, the planet disc gear and the input shaft reversely rotate, the transmission ratio is the wave number of the planet disc gear rail, the transmission ratio of planet disc gear fixed teeth on the peripheral side of the planet disc gear to middle shell fixed teeth on the inner side of a middle shell is the same as the transmission ratio of the planet disc gear rail at the leftend of the planet disc gear to the transmission ball, composite transmission is carried out, the planet disc gear rotates, a planet disc gear groove in the right side can drive a constant-speed ball to rotate, and therefore, an output shaft is driven to rotate. The movable teeth and the fixed teeth are in composite transmission, the meshing area is increased, backlash is eliminated, and the transmission precision, the bearing capacity and the transmission stability are improved.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a speed reducer with no backlash in the combined transmission of movable teeth and fixed teeth. Background technique [0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The movable tooth transmission can meet the requirements of compact structure, high transmission efficiency, wide range of transmission ratio, and large load capacity. The corresponding movable tooth transmission theory and technology are getting better and better. mature hair. Fixed gear transmission technology is the most mature and widely used, but the backlash problem of fixed gear transmission has never been solved. The existence of backlash reduces the transmission accuracy of fixed gear transmission. For this reason, only by developing a reducer that eliminates backlash can it be applicable to the development ne...
