An annular cooling jacket is machined around the front bearing of the electric spindle and the motor stator. The coolant is sent to the annular cooling jacket of the front bearing and the stator through the inlet channel of the outer casing to cool the front bearing and the stator. stator, and then drain the coolant through the outlet of the jacket. The main problem of this traditional cooling method is: the annular cooling jacket of the motor and the bearing is limited by the wall thickness of the outer casing of the electric spindle, the space height of the water jacket is very small, generally about 2-4 mm, and the impurities in the cooling liquid are easy to get in This narrow cooling cavity accumulates, forming a cooling dead angle and uneven cooling, which will seriously lead to blockage, the cooling fluid cannot flow, and the cooling failure will lead to damage to the electric spindle.
