【Abstract】 Taking the parallel planetary gear reducer in the submersible single screw pump oil-extraction system as the target of research,combining with the displacement formula of elastic torsional geometric large deformation of equalized circular sectioned rod and through the calculation of Matlab software the mathematical model of torsional deformation of parallel sun gear shaft in the parallel planetary gear reducer was established.Using the coordination principle and the uniform power transmission principle of torsional deformations in each section of parallel sun gear shaft,the parallel planetary gear reducer was designed.The radial dimensions of this reducer could be minimized to a large range under the condition of transmitting rated power.更多还原
