The correct configuration of spherical roller bearings refers to the combination of bearing types and the arrangement of front and rear bearings. Different configurations determine the different load capacity, running speed, stiffness, temperature rise and service life of the machine tool spindle, especially for stiffness and temperature. The effect of lifting is more significant, so the spindle bearing should be reasonably configured according to the requirements of the working characteristics of the machine tool. In terms of function and structure, the main shaft bearings can be divided into two categories: rolling bearings and plain bearings.
The purpose of running-in operation is to make the bearing and roller raceway through running-in before the bearing is formally angled. It can have good contact conditions to maintain good contact accuracy of the bearing and avoid the bearing at high speed and Heavy-duty use causes damage to the rollers and raceways, which improves the bearing life and accuracy. 'Because tapered roller bearings are not in full rolling contact, there is sliding between the end face of the roller and the shoulder of the inner ring. If the contact conditions are not good, the phenomenon of occlusal damage is easy to occur.
The mechanical spindle refers to the axis on the machine tool that drives the workpiece or tool to rotate. Spindle components are usually composed of the main shaft, bearings and transmission parts (gears or pulleys). In the machine, it is mainly used to support transmission parts such as gears and pulleys, to transmit motion and torque, such as machine tool spindles; some are used to clamp workpieces, such as mandrels. Except for machine tools whose main movement is linear motion, such as planers and broaching machines, most machine tools have spindle components. The motion accuracy and structural rigidity of the spindle components are important factors that determine the machining quality and cutting efficiency
