Abstract
The invention discloses an open type single-stage inner transmission rotary compressor which comprises a cover, a driving disc, a rotary shaft, sliding sheets, a base support, a driven rotor, a transmission shaft and an engine. Inner teeth are machined in the side wall of the driving disc. Outer teeth are machined on the outer circle of the driven rotor. The center of the transmission shaft and the center of the rotary shaft are spaced by a certain distance. The outer teeth of the driven rotor are meshed and matched with parts of the inner teeth of the driving disc. The driven rotor purely rolls in the driving disc along the inner teeth of the driving disc. The driven rotor is driven by the inner teeth of the driving disc to rotate, the driving disc, the sliding sheets and the driven rotor are the same in rotating direction, the relative movement of the sliding sheets and the inner wall of the driving disc is equivalent to the rotating speed difference of the driving disc and the driven rotor, relative friction losses are reduced, and friction power consumption is reduced. Meanwhile, the situation that the sealing performance is lowered due to the fact that the matching clearance of part surfaces is increased by friction is reduced, and the running performance of a refrigeration system is improved. The open type single-stage inner transmission rotary compressor is simple in structure, convenient to machine and assemble, safe and reliable, and energy saving and environment friendliness are achieved.
