Abstract

The invention provides a rolling rotor type compressor. The rolling rotor type compressor comprises a shell, a motor assembly, a compression assembly and a crankshaft. The compression assembly comprises an air cylinder. The ratio of the outer diameter of the crankshaft to the inner diameter of the shell is within a certain range, and the ratio of the outer diameter of the crankshaft to the inner diameter of the air cylinder is within a certain range. The shaft load of the compressor is further reduced, abrasion is reduced, energy efficiency is improved, and miniaturization of the compressor is facilitated.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rolling rotor compressor. Background technique [0002] For compressors, the cold-to-weight ratio is one of the key performance indicators. The cold-to-weight ratio refers to the ratio of the rated cooling capacity of the compressor to its weight. In the process of researching and manufacturing compressors, it is necessary to maximize the refrigeration capacity while minimizing the size and weight of the compressor in order to improve the competitiveness of the product and obtain the best economic benefits. Therefore, as a common compressor, the miniaturization of the rolling rotor compressor is a trend. However, limited by the strength of the crankshaft and the space utilization in the compressor housing, the compressor with a small housing diameter cannot reach the same level as the compressor with a large housing diameter in terms of refrigeration capacity and efficien...
