| Abstract: | The supporting axle of 40Cr steel is difficult to be assembled awing to the distortion arized from heat treatment. According to trasformation principle the supporting axle was quenched after nut has been assembled on screw-thread of the axle, As a result, expanding amount of screw-thread of the axle was reduced and the difficulty of assembly was solved. |
