Title:

CRANKSHAFT AND ROTARY COMPRESSOR

Document Type and Number:

WIPO Patent Application WO/2018/076480

Kind Code:

A1

Abstract:

Disclosed are a crankshaft and a rotary compressor comprising the crankshaft. The crankshaft (1) comprises a long shaft (11) and a short shaft (12). A ratio of an external diameter of the long shaft (11) to an inner diameter of a compressor shell (2) is less than 0.14 and greater than 0.07, and a ratio of an external diameter of the short shaft (12) to the inner diameter of the compressor shell (2) is less than or equal to 0.12 and greater than 0.05, thereby reducing the area of a contact surface and a frictional loss of the crankshaft (1) during work, thus the coefficient of performance (COP) of the compressor is improved.
