面を損傷させるという問題点を有していた。Problems that the invention aims to solve When converting the quality from iron-based materials to aluminum alloy materials,
The outer diameter of the bearing 6, which is made of iron-based material, and the inner diameter of the bearing insertion hole 7 of each side plate 4, which is made of aluminum alloy, vary depending on the temperature associated with the operation of the rotary compressor due to the difference in the coefficient of thermal expansion of the materials. Due to the rise, the outer diameter of the bearing 6 is thermally expanded and the bearing insertion hole 7
The inner diameter thermal expansion of the bearing insertion hole 7 becomes larger, and the bearing insertion hole 7
When operating a rotary compressor at a temperature of 1 t, where the inner diameter of the bearing 6 is larger than the bearing outer diameter by more than the press-fit interference with the bearing 6 when press-fitted at room temperature, the bearing 6 is not regulated in any way with respect to the bearing insertion hole 7. However, there was a problem in that the side plate end face 4a protruded, damaging the rotor end face.
