Oldham ring manufacturing method of scroll compressor and Oldham ring

摘要

The present invention relates to a method of manufacturing an Oldham ring of a scroll compressor and to an Oldham ring.;In the present invention, the Oldham ring for preventing the rotation of the orbiting scroll in the scroll compressor is separately manufactured and then integrated by welding.;According to the present invention, there is provided a method of manufacturing a ring, comprising the steps of: preparing a ring having at least one vertically penetrating engagement hole in a circumferential direction and having projections diametrically opposed to either one of the upper and lower sides; A step of manufacturing an engaging pin for manufacturing a engaging pin, a step of engaging the rear faces of the pair of rings completed by the ring making step and fixing the engaging pin so that the engaging pin is orthogonal to each other, And a welding step of welding the coupling pin so that a pair of rings are integrated after finishing the fin coupling step.;According to another aspect of the present invention, there is provided an electronic device comprising: a first ring having a first projection opposed to a first side in a radial direction and having at least one first coupling hole vertically penetrated therethrough; A second ring having a second projection orthogonal to the first projection and diametrically opposed to the other side of the first projection and having at least one or more second engagement holes aligned vertically with the first engagement hole, And the coupling pin is fitted to the first and second coupling holes.
