Rotor of rotary electric machine
专利汇可以提供Rotor of rotary electric machine专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a rotor having a spider with good strength balance by forming a coupling means with a ring divided in the axial direction and with a bolster having a dovetail prepared on the outer periphery of said ring. CONSTITUTION:A bolster 9 having a dovetail on a spider 2 is settled by welding on the outer periphery of a ring 7a axially divided and thereon an armature iron core 1 is laminated to couple the armature iron core 1 by an endplate key 12 through the endplate 4. Thereby the inflow torque from the divided ring 7a to the main plate 6 is equalized in the right and left thereof to obtain a rotor having the light and cheap spider with good balance of strength. Further the preparation of the bolster 9 and the divided ring 7a makes the ventilation passages (a) and (b) to be formed thus improving a cooling effect.，下面是Rotor of rotary electric machine专利的具体信息内容。
