In order to increase the diameter of the main shaft within the allowable range, light series rolling bearings are often used. These bearings have a larger diameter in the inner diameter of a certain diameter, and a larger main shaft diameter can be obtained. Under the premise of meeting the structural requirements, the best support span should be used as much as possible. When a larger or smaller bearing span has to be used for structural reasons, a method of increasing the stiffness of the bearing or increasing the stiffness of the spindle can be sought to compensate for the impact of the span. Adopting high-rigidity rolling bearing and reasonable pre-tightening In order to improve the rigidity, in addition to the ordinary rolling bearing, the main shaft component can also adopt various special structure rolling bearings to improve its rigidity, the main shaft journal, the bearing seat hole and the like. The geometrical accuracy and surface roughness of the mating surface should meet certain requirements. Analysis of vibration resistance and wear resistance of spindle components. The vibration resistance of the suspension vibrational spindle component refers to the ability of the cutter cutter to maintain the normal operation of the main shaft of the flying cutter roller without vibration. The spindle components have poor vibration resistance and are prone to vibration during operation, which will reduce the durability of the cutter roller during operation and even cause a knife. Therefore, vibration resistance is one of the most important performance indicators of the spindle components. Theoretical analysis and experimental results show that the main factors affecting the vibration resistance of the spindle components are its structural stiffness and damping characteristics. The greater the stiffness and damping ratio, the less self-excited vibration is generated, and the less the forced vibration. Therefore, the main way to improve the vibration resistance of the spindle components is to increase the stiffness of the spindle, as above. Increasing the resistance of the main shaft components The damping performance of the main shaft with sliding bearings is much better than that of rolling bearings. The tapered roller bearings in rolling bearings are better than ball bearings.
