The application technology of the progressive shaft support rigidity has a great effect in improving the rigidity of the shaft support; it is described as follows:
(1) For the bearing-like external appearance of the bearing shaft and the bearing device on the seat hole; the lower the surface roughness; the better the shape and orientation accuracy; the higher the support rigidity is.
For the above-mentioned external appearance, the surface is strengthened and treated; it is advantageous to improve the rigidity. The high-hardness plug with low roughness is used; the punch is repeatedly pressed and exited in the smooth state with a certain interference; it is also beneficial to improve the support rigidity. If necessary, the collar can be similarly treated with a snap ring.
