The Virtual Design of Planetary Gear Reducer Based on Pro/E

Planetary gear reducer is used widely for a variety of transmission ratio,compact structure,high efficiency.However,the reducer structure is complex and the design is difficult.It is easy to produce all kinds of interference in fabrication,assembly and work,affecting its normal work.In order to detect interference between parts of the assembly to amend the original design,improve design quality,three-dimensional design software Pro/Engineer can be used to complete the reducer parts 3D modeling and parametric design,virtual assembly,assembly interference check and structure rationality examination.The test results show that parametric technology and virtual prototype technology can be used to examine directly each kind of interference and the unreasonable structure which appear in the gear reduce model.And it can improve design efficiency and product quality.
