| Planetary gear reducer submersible submersible screw system as an integral part, due torestrictions by the radial size screw, resulting in too little gear reducer. In order to solve thelarger torque transfer in a limited radial space problem, this paper analyzed for parallelplanetary gear.First, conventional submersible submersible screw planetary gear system is analyzed anddesign; on this basis in order to increase the carrying capacity of the gear unit, using twoparallel sun wheel, and each sun wheel and three planetary gear meshed The structure,designed in parallel planetary gear. UG software using conventional planetary gear reducerwith parallel planet were designed assembly modeling and motion simulation, by analyzingthe simulation results verify the reasonableness of the design. And UG models built directlyinto the finite element analysis software ANSYS Workbench, respectively, these two planetarygear tooth root bending finite element in contact with the tooth surface analysis and the resultsshow that: the parallel planetary gear reducer planetary gear, sun axle, the ring gear and thestress and deformation of the whole is better than the conventional monopole planetary gearreducer. Finally, co-simulation application ANSYS Workbench and UG between analysis anddesign optimization objectives, quality minimum target for parallel planet planetary gear rackoptimized design, optimization results show the rigidity of the structure of the carrier hasincreased, the quality of than before optimization to reduce the14%, the optimized structure ismore reasonable.Results of this study to enhance the carrying capacity submersible screw system and theimprovement of life provides a theoretical reference. |
