In the machine tool bearings, SKF bearings is widely used. SKF bearing spindle for certain technical requirements. The following describes a content analysis to everyone. Rotational speed and temperature with the scientific and technological development, more and more high spindle speed, speed range and thus the greater the bearing high speed stability requirements are also increasing.
1.SKF bearings Machine tool spindle bearing temperature is an important factor in limiting speed of the bearing. Under normal circumstances, the right choice bearing type, tolerance levels, configuration, clearance (preload) size, lubricants and lubrication, etc., to a certain extent, improve the speed performance of rolling bearings.
2.carrying capacity and life in general machine tools, the spindle assembly to maintain its life mainly refers to the period of use precision spindle, therefore, required to maintain the accuracy of bearing performance to meet the requirements of the spindle component life. For heavy-duty machine tools or powerful cutting machine, you should first consider the bearing capacity.
3 stiffness and vibration resistance in order to ensure the quality of the machining, the spindle system must have sufficient rigidity, otherwise it will have a greater re-mapping error even flutter. Vibration resistance refers to the forced vibration and self-excited vibration capability. Spindle assembly vibration resistance depends on the spindle and bearing stiffness and damping. Using the preload bearing can effectively increase the stiffness of the spindle system.
4. SKF bearings Noise in high-speed grinder, the grinding noise and bearing noise is the main ingredient should be used in low-noise rolling bearings.
