Motor servo spindle radiating device

The invention discloses a motor servo spindle radiating device. The device comprises a heat conducting ring which sleeves a spindle. Multiple radiating fan blade combinations extend outward from the outer surface of the heat conducting ring. Each radiating fan blade combination includes two radiating fins arranged in parallel. The device further comprises a discoid radiating cover. The radiating cover is provided with a shaft hole through which the spindle passes. The back of the radiating cover is provided with a plurality of air inlets. Air inlet pipes are installed on the air inlets respectively. The back of the radiating cover and the top of a motor are fixed by a connecting rod. Through an air cooling mode, heat of the spindle can be radiated effectively, and the temperature of the spindle is thus lowered. The unique double-blade structure can reduce the drag coefficient of the spindle and reduce capacity loss while taking away heat quickly. 本发明公开了种伺服电机主轴散热装置，包括有套接在主轴上的导热圈，导热圈外表面向外延伸出有多组散热扇叶组合，每组散热扇叶组合包括
