Among the factors affecting the rotational speed and performance of the electric spindle, thermal deformation is associated with lubrication. The internal heat source of the electric spindle comes from two aspects: the heat generated by the built-in motor and the spindle bearing.
The heat generated by the spindle bearings can be solved by using oil and gas lubrication. The bearing size of the electric spindle is not too large and does not require a large amount of lubricating oil to lubricate. If a large amount of lubricating oil is used for intrusive lubrication by conventional lubrication, the method is not preferable, mainly because it does not provide good lubrication and wastes a large amount of lubricating oil. During the continuous circulation of the lubricating oil, the oil temperature rises due to the friction between the oil molecules, and the temperature rise is not conducive to the operation of the electric spindle. Therefore, bearing oil and gas lubrication is selected. This kind of micro-lubrication method can reduce the supply of lubricating oil, not only eliminates the heat generated by the friction of a large amount of oil molecules, but also has better lubrication effect. Bearing oil and gas lubrication, in the oil supply to follow a single small amount of principle, each time in a very small amount of quantitative oil, increase the oil frequency to meet the bearing lubrication requirements. This kind of lubrication method is that the compressed air drives the lubricating oil film to the friction surface, and the lubricating oil fully plays the role of lubrication. The compressed air can also take away the heat generated by the friction and play a cooling role.
The selection of bearing oil and gas lubrication, the summary advantages are as follows:
1,
The amount of lubricating oil consumed is low, saving costs,
2. The lubrication effect is good, which guarantees the design performance of the electric spindle.
3,
The compressed air can take away the heat generated inside the electric spindle, effectively preventing the bearing from deforming due to heat.
4. Positive pressure inside the bearing to prevent intrusion of impurities.
Highlights the advantages of high-speed bearing lubrication with oil and gas lubrication
Bearings are an indispensable part of mechanical equipment. The reliable operation of bearings in electric spindles is more important and directly affects the performance of machine tools. In addition to the influence of its own material, the choice of lubrication cooling method is also very important. To achieve high-speed cutting of the machine tool, firstly, the rotation speed of the shaft is high, and the high rotation speed requires stable bearing performance. Lubrication is an important factor to ensure the performance of the bearing. Bearing oil and gas lubrication, the bearings can be well lubricated, the electric spindle runs more stable, and good operating indicators are obtained.
