High-rigidity temperature-controlled high-speed core running motorized spindle

Abstract

The utility model relates to high -speed core machine technology field, and disclose a kind of high rigidity temperature control type high -speed core machine motor spindle, including pivot, the arc surface of pivot is fixedly connected with three connecting blocks, the arc surface of three connecting blocks is fixedly connected with sleeve, the arc surface of sleeve is fixedly connected with rotor core, the inner surface of rotor core is fixedly connected with rotor winding, the arc surface of pivot is fixedly connected with multiple ball bearings, the arc surface of ball bearing is fixedly connected with spacer sleeve, and spacer sleeve is slidably connected with each other, the arc surface of ball bearing is fixedly connected with inner sleeve, the inner surface of inner sleeve is fixedly connected with insulating sleeve, the inner surface of insulating sleeve is fixedly connected with permanent magnet. In prior art, when working at high strength and long time, the rigidity of motor spindle is insufficient, and it is easy to cause temperature to be too high, affect the service life of main shaft, reduce the shortcoming of progress.
