under normal circumstancesHigh-speed spindleIt can perform high-density and fast movement, so it has become an indispensable motor equipment in many precision manufacturing industries. Since the high-speed spindle with high evaluation has a reasonable structural design, it can obtain better dynamic performance and service life in specific applications. What are the components of the high-speed spindle? Let's take a look at the components of the high-speed spindle together.
1. Axle shell
The shaft housing is an important part of the high-speed spindle. In addition to making the appearance design of the high-speed spindle more beautiful, it can also protect the internal parts of the high-speed motorized spindle. The accuracy of both the size and position of the shaft shell will have an important impact on the overall accuracy of the spindle, so under normal circumstances, the bearing seat hole is designed directly on the shaft shell.
2. Rotary shaft
The main body of rotation of the high-speed spindle is the rotating shaft. Its manufacturing accuracy will directly affect the final accuracy of the high-speed spindle as a whole. Therefore, the geometrical tolerances and dimensional accuracy requirements of the rotating shaft are very high. At the same time, since the rotating shaft will generate a certain eccentric mass during high-speed operation, which will cause large vibration and affect its dynamic performance, it is necessary to maintain the dynamic balance of the rotating shaft.
3. Bearing
Bearings are a core support component in high-speed spindles. For high-quality high-speed spindles, the maximum speed depends on the size, location and lubrication method of the bearing. Therefore, if it is suitable for high-speed operation, a highly standardized bearing must be selected to ensure that the bearing has good high-speed performance. High dynamic load bearing capacity and small heat generation, so that the high-speed spindle has the advantages of high rigidity, high power and long life.
The three aspects introduced above are the main components of the high-speed spindle. In addition to other components such as stator and rotor, these components together constitute a spindle motor that can run at high speed, so as to ensure good running performance in various high-precision equipment, and give full play to the application of high-speed spindle. some effect.
