    • PURPOSE: A laminated rotor core of a motor is provided to prevent a shaft and a rotor core member from running idle, thereby facilitating easy press-fitting of a shaft. CONSTITUTION: A laminated rotor core comprises a rotor core member(10), a shaft(20), and at least one or more keys(21). The rotor core member includes a shaft hole extended to a direction of a rotation shaft and a key groove communicating with the shaft hole. The shaft is press-fitted into the shaft hole. A key accommodation groove is concavely formed at a peripheral position corresponding to that of the key groove. The at least one or more keys is formed at the key groove and the key accommodation groove to restrict the rotor core member and the shaft.
    • 目的:提供电动机的层叠转子铁芯,以防止轴和转子铁芯构件怠速运转,从而便于轴的容易压配。 构成:层叠的转子芯包括转子芯构件(10),轴(20)和至少一个或多个键(21)。 转子铁芯构件包括延伸到旋转轴的方向的轴孔和与轴孔连通的键槽。 轴被压入轴孔。 在与键槽相对应的周边位置凹入地形成钥匙容纳槽。 所述至少一个或多个键形成在所述键槽和所述键容纳槽处以限制所述转子芯部件和所述轴。
