ABSTRACT:
A cooling loop structure of high speed spindle comprises three groups of cooling areas where the first group being the front bearing cooling area, the second group being the motor cooling area and the third group being the rear bearing cooling area. Cooling fluid from the cooling machine outlet, flows through the rear end of spindle into the front bearing cooling area, then flows into the motor cooling area, finally, after flowing into the rear bearing cooling area, it flows back into the inlet of cooling machine, thereby, forms a temperature-controlled cooling loop. The cooling loop needs only a setup of cooling fluid inlet and outlet at the rear end of spindle which can avoid being using too many exposed cooling pipes that result in space occupation and being inconvenient in the installation of spindle. There is a setup of O-ring with different diameters designed at both ends of cooling jacket in the spindle where the diameter of O-ring groove closed to the center of the spindle is smaller than the one closed to both ends of the spindle. Besides, the front bearing cooling area is designed to be an encircling structure with fluid flows axially and rotates radially such that it not only can effectively control the temperature rise of the front bearing area but also can reduce the volume of the front end of the spindle to facilitate in getting deeply into the work pieces to perform bore machining.
