SCROLL COMPRESSOR COMBINED OLDAM COUPLING STRUCTURE

摘要

A scroll compressor according to the present invention includes: a housing having a driving instrument for making a driving force by a driving shaft; a fixated scroll fixated and installed on one side of the housing; a circling scroll connected to the driving shaft to perform a circling motion about the fixated scroll; a compressing chamber formed between the fixated scroll and circling scroll; and a main frame prepared on one side in the order of a ring-shaped Oldham coupling for preventing rotation when the circling scroll rotates, and the circling scroll, while being coupled to the housing. By the same, a counterpart object for sliding near the Oldham coupling is made of different material to reduce the effect of inertia and to guarantee a reliability of the product by increasing the oscillation properties. By comprising the Oldham coupling with aluminum alloy lighter than steel, the weight of the compressor can be lightened than a traditional model, thus weight-lightening an automobile and promoting an improvement of mileage of the automobile.
