Title:
ROTOR-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/007110
Kind Code:
A1
Abstract:
A rotor-type compressor. The compressor comprises a first support assembly and a second support assembly (111); the first support assembly is an upper supporting assembly, and is coaxially provided with the end of a crank (102) passing through a rotor in a clearance fit; the second support assembly (111) is a main bearing and has a height of H; a fit clearance S of the clearance fit falls within the following range: 0.001≤S/H≤0.005. For the rotor-type compressor, the integral structure is optimized by controlling structural parameters of upper and lower support parts, such that bearing abrasion is relieved, and the operation stability and service life of the compressor is improved.
