Abstract:  For the characteristics of transmission ratio, small center distance, interference on translational motor body, the design method of involute gear for translational meshing motor was proposed. Considering the conditions of interference and coincidence degree, the trail calculation were applied using the tooth profile parameters calculated from given modulus, number of teeth, pressure angle and modification coefficient. The modification coefficient, center distance and other structure parameters were obtained from the trail calculation. The internal meshing gears was designed and processed based on proposed method. The novel translational meshing motor using designed involute gears operates successfully and efficiently which testify the validity and feasibility of proposed method.
