Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/181914
Kind Code:
A1
Abstract:
A rotary compressor according to the present embodiment comprises bearing parts provided respectively on both sides of an eccentric part, and a roller alignment part which may be formed between the eccentric part and at least one bearing part so as to align an assembly position of a roller before the roller is inserted into the eccentric part. Accordingly, the roller can easily be assembled to the eccentric part even when the outer diameter of the bearing part is increased, such that the outer circumferential surface of the bearing part further protrudes in the radial direction compared to the outer circumferential surface of the eccentric part. As such, the compressor can be miniaturized by reducing the length of the bearing part in the axial direction while securing a bearing area by increasing the outer diameter of the bearing part.
