Embodiment Construction
[0053] In order to ensure the stability of the spindle system, the design of the conventional high-speed hydrodynamic spindle system must strictly limit a series of parameters such as the stiffness, mass, span, and structure of the spindle, so that the design speed is lower than the critical speed. However, when the parameters of the spindle are limited and the operating speed of the spindle is higher than the critical speed, the traditional design method of the spindle system is no longer applicable.
[0054] In order to solve the above problems, the present invention ensures the safety and stability of the spindle system under critical speed conditions by rationally designing the multi-scale interface of the bearing, and proposes a design method for a transcritical spindle system based on multi-scale interface regulation. Transcritical spindle system, a transcritical spindle system is a spindle system that can work normally across critical speeds, and the multi-scale interfac...
