Abstract
In a method for manufacturing an anti-rotation ring of a scroll type compressor, wherein the anti-rotation ring is provided in an anti-rotation mechanism for preventing a movable scroll from rotation on its own axis and made of a metal, the steps of the method include drawing a steel plate into a first intermediate body having a bottomed cylindrical shape, punching the bottom of the first intermediate body thereby to make a second intermediate body and ring forming the second intermediate body.
Claims1
An anti-rotation mechanism of a scroll type compressor comprising:
- an anti-rotation ring having a cylindrical shape with both ends;
- and
- a pin having opposing end surfaces formed in an axial direction of the pin and inserted into the anti-rotation ring and in sliding contact with an inner peripheral surface of the anti-rotation ring,
- wherein a shock line is formed as a groove in a peripheral direction in the inner peripheral surface of the anti-rotation ring adjacent to one of the both ends in a manufacturing process,
- wherein the pin is inserted in the anti-rotation ring at a position where an outer peripheral surface of the pin crosses over the shock line in the inner peripheral surface of the anti-rotation ring.
