Abstract

The present invention relates to a kind of gear rotor compressor, the compressor includes an inner rotor with a first axis and some teeth thereon, the number of teeth is Z1; an outer rotor surrounding the inner rotor, with Z2 teeth more than that of the inner rotor; a shaft of a driving equipment connected to the inner rotor, the driving equipment drives the inner rotor; and a plurality of orifices through which the fluid medium is sucked in and discharged after compressed. The teeth of the inner rotor engage in the alveolus in the outer rotor.

Claims

5 权 利 要 求 书 5 claims 1. 一种齿轮式转子压缩机包括： 一个具有第 1齿数 Z1且定义第 1中 心轴线的凸齿外转子； 一个具有第 2齿槽数 Z2且定义第 2中心轴线的带 有相反方向齿槽的外转子； 一个带有两个端盖， 用于放置转子的壳体。 第 2齿槽数 Z2比第 1齿数 Z1大， 凸齿转子置于齿圈转子内并带动齿圈转子 转动， 第 1轴线与第 2轴线有一偏心距， 由此形成凸齿转子与齿圈间的一 些空间， 以供吸入与压缩工作介质； 两侧端盖用于密封诸工作腔。 1.
