AI Technical Summary
Existing electric spindle cooling systems cannot effectively dissipate heat, causing the bearing inner ring and rotor area to overheat and deform, affecting machining accuracy and stability.
It adopts two independent cooling systems, one internal and one external. The internal cooling system is connected to the water inlet and outlet channels inside the spindle through a rotating connector. Combined with the cooling ring cavity and fan-shaped cavity structure, it can effectively cool the inner ring of the front bearing assembly, the rotor, and the inner ring of the rear bearing assembly.
It improves the machining accuracy and stability of the electric spindle, avoids the phenomenon of external cooling and internal heating, and ensures the uniformity and effectiveness of cooling during high-speed rotation.
