Abstract

The invention discloses a double-cylinder rotary compressor, which comprises: a first air cylinder, a second air cylinder, an intermediate bearing plate and a crankshaft. The intermediate bearing plate is located between the 1st cylinder and the 2nd cylinder. The main bearing connected to the 1st cylinder and the end plate connected to the 2nd cylinder. The crankshaft includes a main shaft that slides on the main bearing, a first eccentric shaft and a second eccentric shaft that drive the first piston and the second piston, respectively, and an intermediate shaft located between the first eccentric shaft and the second eccentric shaft. At least one of the first eccentric shaft and the second eccentric shaft is separated and combined with the crankshaft, and the intermediate bearing plate is in sliding fit with the intermediate shaft. According to the double-cylinder rotary compressor of the embodiment of the present invention, the reliability of the crankshaft can be improved, the crankshaft can run at high speed, the sliding loss is reduced, the compression efficiency is improved, and the eccentricity of the crankshaft can be enlarged.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a double-cylinder rotary compressor. Background technique [0002] The two-cylinder rotary compressor, which was mass-produced around 1988, can operate in a wide range from a low speed of 15rps to 120rps compared with a single-cylinder rotary compressor. In recent air conditioners, APF (seasonal efficiency) is required to be improved, and it is necessary to expand the operating range while reducing the size of the compressor, and to take into account both APF improvement and comfort. [0003] That is, it is necessary to reduce crankshaft sliding loss by downsizing the compressor, and to ensure comfort and reliability in high-speed operation such as 150 rps. In order to meet this requirement, it is preferable to have a sliding support for the intermediate shaft connecting the 2 eccentric shafts. But it can't be achieved. [0004] As a means to improve the vibration of the crankshaft,...
