According to configurable trait of oil-free scroll compressor,establish rational technique route of virtual design and introduce the full process of designing scroll compressor which consists of virtual modeling of part,virtual assembly of sample machine,research of feasibility with virtual design by using of Pro/Engineer.

The locomotive work surface produces a lot of power losing and leaks abundance of gas medium because of friction when oil-free scroll compressor is working.

In allusion to work trait of oil-free scroll compressor,add seal element which is made of lubricative material to the scroll teeth and the tangent plane between bracket and whisht scroll in order to realize oil-free technique for scroll compressor successfully.
