| 摘要 |
An external rotor motor has an external rotor (22) with rotor bell (24) and a shaft (28) and a stator on which is provided a bearing support/carrying tube (70), and anti-friction bearings (52,60) are arranged in the bearing support tube and serve to mount the shaft (28) of the external rotor (22) and of which the proximal anti-friction bearing (52) is arranged nearer at the rotor bell than the distal anti-friction bearing (60), in which the shaft is made displaceable in an axial direction in the inner rings (56,64) of this anti-friction bearing. A securement member (50) serves to retain at least the proximal anti-friction bearing in position after assembly in the bearing support tube. An Independent claim is included for an assembly method for the rotor of an external rotor motor. |
