Problems solved by technology

In this state, if the operation starts, the lower bearing 61 will be loaded due to the rotational force of the rotating shaft 37, and thus the efficiency of the compressor will decrease.
[0011] In addition, due to friction with the rotating shaft 37, the inner surface of the lower bearing 61 will be worn, and in the process, the compressor will vibrate

Abstract

The invention relates to a rotational axis support device of a compressor, which comprises a support assembly which is arranged inside a shell; a lower bearing which can be inserted into the support assembly by combining a rotor of a drive motor to rotate, and rotatablely combining a rotational axis which conveys rotary force to a compression part. The invention is characterized in that the rotational axis support device also comprises an elastic assembly, which is positioned between the support assembly and the lower bearing, and elastically supports the radius direction of the rotational axis. The loading of the lower bearing caused by the rotary force of the rotational axis can be prevented, the reliability of the compressor can be improved, and the vibration generated during the process of the abrasion of the inner face of the lower bearing can be prevented by using the structure.

Description

Technical field: [0001] The present invention relates to a rotating shaft supporting device of a compressor. More specifically, the present invention relates to a device for reducing frictional loss and improving efficiency by reducing the load on the lower bearing caused by the rotating force of the rotating shaft. The rotary shaft support device of the compressor improves the reliability of the compressor by preventing the wear of the lower bearing and preventing vibration. Background technique: [0002] figure 1 It is a longitudinal sectional view of a prior art compressor. figure 2 yes figure 1 Enlarged view of the section view of the support device in the lower region of the middle axis of rotation. image 3 yes figure 2 exploded perspective view. [0003] As shown in the figure, the compressor includes: a housing 11 that forms a closed storage space inside; a compression part 21 that is housed in the inside of the housing 11 and compresses the refrigerant; The ...
