SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP2017053250
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a scroll compressor in which smoothness on an inner ring transfer surface is kept, and in addition, an inner ring is efficiently cooled and reliability is improved.SOLUTION: A scroll compressor comprises: a sub-bearing 23 for supporting a rotating shaft 10; an oil reservoir for storing lubricant oil at a bottom part of a closed container; and a bearing part housing cover 95 positioned at an upper part of the sub-bearing. The rotating shaft has a first oil supply passage 22 formed in an axial direction of the rotating shaft and a second oil supply passage 24 which is branched from the first oil supply passage and is formed in a radial direction of the rotating shaft. An oil supply space is formed by the bearing part housing cover, a slit 56 at an end part of the second oil supply passage is arranged to be opened in an oil supply space 25 and at the same time, and at a lower part of the oil supply space that is a position closer to the rotating shaft from the center of a rolling body 23c of the sub-bearing is provided with an oil supply port 95a. Thereby the lubricant oil at the oil reservoir part is discharged to the inside of the oil supply space via the first oil supply passage of the rotating shaft, the second oil supply passage and the slit, and further supplied from the oil supply port to the sub-bearing.SELECTED DRAWING: Figure 3
