Title:
BEARING STRUCTURE AND SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP2017082842
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bearing structure capable of avoiding one-side contact of a driving shaft to a bearing and capable of avoiding deviation between an axial center of the driving shaft and an axial center of the bearing, and a scroll compressor including the bearing structure.SOLUTION: A driving shaft 11 includes a shaft body 81, and a cylindrical part 82 arranged between the shaft body 81 and a bearing 51, and integrated with the shaft body 81 or integrally fixed to the shaft body 81. At an intermediate part in an axial direction of the cylindrical part 82, a swollen part 88 is configured to be swollen radial outward or deform so as to be swollen. At least a part of the bearing 51 is configured to enable deformation along the swollen part 88 of the cylindrical part 82.SELECTED DRAWING: Figure 4
