AI Technical Summary
Technical Problem
In scroll compressors, the bushing may move axially toward the orbital scroll, leading to potential wear between the orbital scroll and the bushing, which compromises the durability of the compressor.
Method used
The design incorporates a bush flange that contacts the bearing flange to prevent axial movement of the bush, and a groove and notch system for efficient oil supply to the bearing flange, ensuring lubrication and positioning of the bush, thereby avoiding direct contact with the orbital scroll.
Benefits of technology
This configuration enhances the durability of the scroll compressor by preventing wear and maintaining lubrication without increasing the number of parts.

Abstract
To improve the durability of the scroll compressor while keeping the number of parts to a minimum. [Solution] When the bush moves in the axial direction of the rotating shaft toward the orbital scroll 26 between the tip of the rotating shaft and the orbital scroll 26, the bush flange comes into contact with the bearing flange 58. The bearing cylinder 57 has a groove 61 that extends to supply oil from the air supply passage 46 toward the bearing flange 58. Therefore, oil from the air supply passage 46 is easily supplied to the bearing flange 58 via the groove 61. The bearing flange 58 has a notch 62 that communicates with the groove 61 and supplies oil toward the outer peripheral edge of the bearing flange 58. Therefore, oil supplied from the groove 61 toward the bearing flange 58 is easily supplied to the outer peripheral edge of the bearing flange 58 via the notch 62.
