The Virtual Design and Assembly of A Multilevel Planetary Reducer

This article mainly introduced carries on the multilevel planetary gear reducer´s virtual design process in the oil drilling platform raising mechanism using the computer virtual prototype technology. The paper on complex mechanical design in a virtual assembly process of the problems has carried on the introduction. In the paper appears question after analytical study has given the theoretical calculation formula and the practices two corresponding solutions. The examples proved that these methods are effective. These methods have the bigger reference value to the similar complex mechanism´s virtual prototype design.
