| Abstract: | Taking 2FG12 high weir type double spiral classifier as example, the new manufacturing tech- nology of the screw shaft assembly welding is introduced. Under the premise of guaranteeing the product quality requirements, the nut is welded on the three slots cut with oxygen welding on the hollow shaft to adjust the circular run-out and then distributed segment welding, alternative to the traditional manufac-turing process of the slender shaft assembly welding, The process scheme can solve the problem of the high concentricity requirements existed in the traditional manufacturing process, large circular run - out and manufacturing difficulties. |
