转子芯加热装置和转子芯热配合方法
摘要：
转子芯加热装置(100)被配置成通过感应加热来对转子芯(150)的内周侧表面和外周侧表面进行加热。转子芯具有中空圆筒形状。转子芯加热装置包括第一线圈(110)、第二线圈(120)和磁通屏蔽夹具(170)。第一线圈被布置在转子芯的内部并且被配置成通过感应加热对转子芯的内周侧表面进行加热。第二线圈被布置在转子芯的外部并且被配置成通过感应加热对转子芯的外周侧表面进行加热。磁通屏蔽夹具具有中空圆筒形状并且被布置成与转子芯的第一端表面相对，其中在第一端表面与磁通屏蔽夹具之间沿转子芯的轴向方向设置有间隙。
摘要（英）：

A rotor core heating device (100) is configured to heat an inner peripheral side surface and an outer peripheral side surface of a rotor core (150) through induction heating. The rotor core has a hollow cylindrical shape. The rotor core heating device includes a first coil (110), a second coil (120) and a magnetic flux shielding jig (170). The first coil is disposed inside the rotor core and is configured to heat the inner peripheral side surface of the rotor core through induction heating. The second coil is disposed outside the rotor core and is configured to heat the outer peripheral side surface of the rotor core through induction heating. The magnetic flux shielding jig has a hollow cylindrical shape and is disposed opposite a first end surface of the rotor core with a gap provided between the first end surface and the magnetic flux shielding jig in an axial direction of the rotor core.
