1.Ways to improve the rigidity of the shaft support The ways to improve the rigidity of the shaft support can be summarized in the following points in principle: (1) Choose high-rigidity bearings; (2) Use bearing application technology to improve the support rigidity; (3) Adjust the main engine appropriately Structural parameters to improve the rigidity of the support.

2.Choose bearings from the viewpoint of supporting rigidity. The essentials for choosing bearings from the viewpoint of supporting rigidity are (1) The rigidity of roller bearings is higher than that of ball bearings; (2) Bearings with large dimensions have higher rigidity than bearings with smaller dimensions, even though NSK Bearings with the same diameter and larger width have higher rigidity than those with smaller widths; (3) Bearings with a large number of rolling elements and bearings with a large number of rows have good rigidity; (4) Bearings with adjustable clearance , Is beneficial to improve the supporting rigidity i (5) If necessary, bearings without inner ring, outer ring or inner and outer ring can be used to reduce deformation links and increase the number of rolling elements.

3.Application technology to improve the rigidity of the shaft support The application technology to improve the rigidity of the shaft support has a great effect, which are described as follows: (1) Requirements for the matching surface of the bearing The bearing installation part on the shaft and the seat hole, the lower the surface roughness, The better the shape and position accuracy, the higher the rigidity of the support obtained. Applying surface strengthening treatment to the above surface is beneficial to increase rigidity.
