具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。下面的详细描述中公开了许多具体细节，以便全面理解本申请。但是，对于本领域技术人员来说，很明显的是，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请的更好的理解。本申请决不限于下面所提出的任何具体配置，而是在不脱离本申请的精神的前提下覆盖了元素和部件的任何修改、替换和改进。在附图和下面的描述中，没有示出公知的结构和技术，以便避免对本申请造成不必要的模糊。
为了更好地理解本申请，下面结合图1至图15对本申请实施例提供的一种电机分瓣或组装装置、电机分瓣方法及电机组装方法进行详细描述。一般地，该电机分瓣或组装装置及电机分瓣方法适用于直径为4.5米以上的电机，但也可以适用于所有尺寸的电机。
本申请中的电机可以为内定子、外转子结构，也可以是内转子、外定子结构。本申请以内定子、外转子的电机结构为例进行方案的说明。本申请中的“径向”指大直径电机的直径方向，也就是定子和转子的直径方向，“轴向”指大直径电机旋转轴的方向，“周向”指大直径电机的圆周方向。
图1示意性地示出了一种具有内定子、外转子结构的电机，该电机包括定子1、转子2、主轴3以及端盖4。主轴3包括同轴设置的固定轴3a、转动轴3b以及设置于固定轴3a与转动轴3b之间的轴承33。定子1通过定子法兰与固定轴3a连接，定子法兰设置于定子轴向中间区域；转子2通过转子法兰与转动轴3b连接，转子法兰设置于轴向端部区域，图1中所示为轴向上端部区域。端盖4将电机包覆，端盖4覆盖转子2的轴向下端部(与转子法兰相对的一个轴向端部)的径向边缘至径向中心区域。
对于大直径电机而言，尤其是兆瓦级别的风力发电机，定子1和转子2之间的磁吸力可以达到数吨级的大小。在将大直径电机进行分瓣和运输的过程中，需要能够克服各分瓣之间的磁吸力以将各分瓣拆分开，因此需要定制牢固的分瓣装置定位，并且经过反复研究和仿真计算，需要设置特定的额外的固定装置来防止各分瓣部件的变形，从多个方面确保拆分电机的过程不会影响电机的电气性能。
图2至图4示出了本申请实施例提供的一种电机分瓣或组装装置。可选地，分瓣的数量为至少两个，沿着电机的周向均匀分瓣。并且可选地，可以对电机的所有大部件，例如定子、转子、端盖等进行全部分瓣加工制造，也可以对定子、转子或端盖的其中至少一个进行分瓣加工制造。当仅对电机大部件中的其中至少一个进行分瓣加工制造时，分瓣加工制造的部件适用于本申请的拆分装置、拆分方法、组装方法以及运输方法，具体如下文所述；其他部件按照传统的制造、运输方法进行，本申请对传统的加工制造运输方法不再赘述。
具体地，该电机分瓣或组装装置包括：图2所示的第一拆分装置10、图3所示的第二拆分装置20和图4所示的套装装置30。
套装装置30用于将电机的第一回转体1与第二回转体2分离或同轴套装。第一回转体和第二回转体中的任一者为定子，第一回转体和第二回转体中的另一者为转子，根据电机的具体结构而定。
第一拆分装置10的示意图如图2所示，该第一拆分装置10用于固定第一回转体1。第一拆分装置10包括可拆卸连接的至少两个第一可分离部101。第一拆分装置10通过拆分第一可分离部101将第一回转体1沿周向分瓣，或者第一拆分装置10通过组合第一可分离部101将第一回转体1的各分瓣段沿周向组装。
可选地，第一可分离部101为包括底部的平面型框架或板体结构，其平面形状适应于第一回转体1的弧形分瓣结构的形状，即可以适应于第一回转体1的分瓣段的形状。进一步可选地，第一可分离部101为在长度方向适应第一回转体1的直径尺寸、在宽度方向适应第一回转体1的半径尺寸的矩形框架或板体结构。另外，第一可分离部101的数量与第一回转体 1的分瓣数量一一对应，这样通过第一可分离部101将第一回转体1的各分瓣段进行固定。可选地，至少两个第一可分离部101通过螺栓等紧固件可拆卸连接。
第一回转体1固定于第一拆分装置10后，通过拆卸螺栓等紧固件，将第一回转体1沿周向分瓣为至少两个分瓣段，每个分瓣段由第一可分离部101支撑并固定。可选地，第一回转体1的分瓣段的数量与第一可分离部101的数量相同。进一步可选地，各分瓣段的分瓣面与各第一可分离部101的拼接面相互平行，以便于由第一可分离部101承载各分瓣段运输至待装配目的地后再次进行组装操作。
第二拆分装置20的示意图如图3所示，该第二拆分装置20用于固定第二回转体2。第二拆分装置20包括可拆卸连接的至少两个第二可分离部201，第二拆分装置20通过拆分第二可分离部201将第二回转体2沿周向分瓣，或者第二拆分装置20通过组合第二可分离部201将第二回转体2的各分瓣段沿周向组装。
可选地，第二可分离部201为包括底部的平面型框架或板体结构，其平面形状适应于第二回转体2的弧形分瓣结构的形状，即可以适应于第二回转体2的分瓣段的形状。进一步可选地，第二可分离部201为在长度方向适应第二回转体2的直径尺寸、在宽度方向适应第二回转体2的半径尺寸的矩形框架或板体结构。另外，第二可分离部201的数量与第二回转体2的分瓣数量一一对应，这样通过第二可分离部201将第二回转体2的各分瓣段进行固定。可选地，至少两个第二可分离部201通过螺栓等紧固件可拆卸连接。
第二回转体2固定于第二拆分装置20后，通过拆卸螺栓等紧固件，将第二回转体2沿周向分瓣为至少两个分瓣段，每个分瓣段由第二可分离部201支撑并固定。可选地，第二回转体2的分瓣段的数量与第二可分离部201的数量相同。进一步可选地，各分瓣段的分瓣面与各第二可分离部201的拼接面相互平行，以便于由第二可分离部201承载各分瓣段运输至待装配目的地后再次进行组装操作。
本申请实施例提供的一种电机分瓣或组装装置，通过套装装置30将电 机的第一回转体1与第二回转体2分离或组装，通过第一拆分装置10将第一回转体1沿周向分瓣或将分瓣后的各分瓣段组装为第一回转体1，通过第二拆分装置20将第二回转体2沿周向分瓣或将分瓣后的各分瓣段组装为第二回转体2，分瓣后的各分瓣段与拆分装置固定连接一并运输。第一回转体1和第二回转体2中的任一者为定子，第一回转体1和第二回转体2中的另一者为转子，有效解决了电机的道路运输超限、运输成本高的问题。
下面结合附图进一步详细描述本申请实施例提供的电机分瓣或组装装置的各部件的具体结构。
请一并参阅图1和图4，套装装置30包括同轴设置的第一套装件31和第二套装件32，如图4所示，第一套装件31包括第一法兰部311，第一套装件31通过第一法兰部311连接第一回转体1；第二套装件32包括第二法兰部321，第二套装件32通过第二法兰部321连接第二回转体2。套装装置30的结构与电机的具体结构有关。为了便于描述，本申请实施例以内定子、外转子结构的大直径电机为例进行说明。
如图1所示，第二回转体2套设于第一回转体1的外周侧，第一回转体1为定子，第二回转体2为转子。第一套装件31还包括与第一法兰部311连接的第一主体部312，第二套装件32还包括与第二法兰部321连接的第二主体部322，第一主体部312与第二主体部322沿轴向重叠设置。
如图4所示，套装装置30的第一套装件31的第一主体部312为筒形圆柱结构，第二套装件32的第二主体部322为类似的筒形圆柱结构，第一主体部312同轴设于第二主体部322的外周侧。第一主体部312与第二主体部322在轴向上具有一定程度的重叠长度。
可选地，第一主体部312与第二主体部322沿轴向重叠的部分的长度大于第一套装件31或者第二套装件32的轴向长度的一半。当吊装第二套装件32以带动转子沿轴向移动时，第二主体部322可以沿第一主体部312的内壁移动，引导第二套装件32带动转子沿轴向移动，从而将转子从电机中拆离。由此，第一套装件31与第二套装件32具有足够的刚度和强度抵抗定子与转子之间的磁吸力而保持不变形，防止转子2在拆离过程中发生偏移卡住而损坏定子，或者无法将转子从电机中拆离。
请一并参阅图1至图3，当第一回转体1为定子，第二回转体2为转子时，第一拆分装置10用于固定并对定子1进行分瓣。如图2所示，第一拆分装置10包括第一固定部11，第一固定部11用于固定定子的定子法兰，每个第一可分离部101包括至少一个第一固定部11。
可选地，第一固定部11呈立柱结构形式的且与第一可分离部101对应的弧形结构，其高度与定子法兰的高度适应。
另外，第一拆分装置10还包括设置于第一固定部11径向外侧的多个第二固定部12，第一可分离部101上设置有至少一个第二固定部12，第二固定部12用于固定电机的端盖4。可选地，第二固定部12还可以用于固定电机的其它非电磁部件。
可选地，第二固定部12可以设置为螺栓等形式的可拆卸固定结构，便于拆卸端盖4。即，可以将电机的其它非电磁部件与第一回转体的分瓣段一起固定在第一拆分装置10的第一可分离部101上运输。
进一步地，第二拆分装置20包括第三固定部23和设置于第三固定部23径向外侧的第四固定部24，第三固定部23用于固定转子2的转子支架轴向一端的转子法兰，第四固定部24用于固定转子支架的轴向另一端；每个第二可分离部201包括至少一个第三固定部22以及至少一个第四固定部23。
对于永磁电机来说，转子2包括转子支架和设置于转子支架的安装表面上的磁极模块。转子2的转子支架沿周向分段为至少两个转子支架段，每个转子段包括转子支架段和若干磁极模块。由于转子支架为薄板结构，第二拆分装置20的第三固定部23和第四固定部24将转子支架的轴向两端均进行固定，可以尽量避免转子支架在运输过程中发生变形。
另外，第一可分离部101还包括第一连接部19，第一可分离部101通过第一连接部19与相邻的第一可分离部101可拆卸连接；第二可分离部201还包括第二连接部28，第二可分离部28通过第二连接部28与相邻的第二可分离部201可拆卸连接。
由于转子支架的安装面上沿周向排布有磁极模块，各转子段之间存在较大的磁吸力，为了便于将转子2分瓣拆分，第二拆分装置20需要具有足 够的结构强度克服分瓣过程中的磁吸力。由此，第二连接部28的轴向高度为h，转子2沿轴向的高度为H，且0.5H<h<H。第二连接部28的轴向高度如此设置，便于稳定地对分瓣的转子段进行支撑，避免转子支架在分瓣过程中发生变形。
可选地，第二连接部28由第二拆分装置20的底部沿竖直方向凸出、并对应于转子段的分瓣面设置，第二连接部28上设置螺栓孔等，螺栓等紧固件可穿过各第二连接部28的螺栓孔对第二可分离部201进行分瓣或组合。
另外，本申请实施例的电机分瓣或组装装置还包括：第一驱动设备(图中未示出)和第二驱动设备(图中未示出)，第一驱动设备用于辅助第一可分离部101对第一回转体1进行分瓣，第二驱动设备用于辅助第二可分离部201对第二回转体2进行分瓣。
在一些实施例中，第一回转体1为定子，第一驱动设备可以为牵引设备，例如手动葫芦，以克服地面的摩擦力将定子的各分瓣拆分。第二回转体2为转子，转子的磁极模块具有磁性，各转子分瓣之间的磁吸力较大，需要借助第二驱动设备克服地面的摩擦力及磁吸力，以将各分瓣拆分开。可选地，第二驱动设备为液压缸或者气缸。
请一并参阅图5和图6，本申请实施例还提供了另外一种电机分瓣或组装装置，其与图2至图4所示的结构类似，不同之处在于，该电机分瓣或组装装置用于辅助拆分内转子、外定子结构的电机，因此第一拆分装置10、第二拆分装置20和套装装置30对应于定子1和转子2的位置的不同而结构有所不同。
具体来说，第一回转体1为转子，第二回转体2为定子，第一拆分装置10用于固定分瓣的转子段。第一拆分装置10包括第五固定部15、设置于第五固定部15径向外侧的第六固定部16，第五固定部15用于固定转子支架轴向一端的转子法兰，第六固定部16用于固定转子支架的轴向另一端；每个第一可分离部101包括至少一个第五固定部15以及至少一个第六固定部16。其中，第五固定部15和第六固定部16沿周向分段为与第一可分离部101对应的弧形结构。
如前所述，由于转子支架为薄板结构，第一拆分装置10的第五固定部 15和第六固定部16将转子支架的轴向两端均进行固定，可以尽量避免转子支架在运输过程中发生变形。
另外，第一拆分装置10还包括设置于第一固定部11径向外侧的多个第八固定部18，且第一可分离部101上设置有至少一个第八固定部18，第八固定部18用于固定电机的端盖4。第八固定部18还可以用于固定电机的其它非电磁部件。
可选地，第八固定部18可以设置为螺栓等形式的可拆卸固定结构，便于拆卸端盖4。即，可以将电机的其它非电磁部件与转子段一起固定在第二拆分装置20的第二可分离部201上运输。
第二拆分装置20用于固定分瓣的定子段，其包括第七固定部27，第七固定部27用于固定定子的定子法兰。每个第二可分离部201包括至少一个第七固定部27。第二可分离部201还包括第二连接部28，第二可分离部28通过第二连接部28与相邻的第二可分离部201可拆卸连接。
另外，第一可分离部101还包括第一连接部19，第一可分离部101通过第一连接部19与相邻的第一可分离部101可拆卸连接；第二可分离部201还包括第二连接部28，第二可分离部28通过第二连接部28与相邻的第二可分离部201可拆卸连接。
如前所述，由于转子支架的安装面上沿周向排布有磁极模块，各转子段之间存在较大的磁吸力，为了便于将转子2分瓣拆分，本实施例中，第一拆分装置10需要具有足够的结构强度克服分瓣过程中的磁吸力。由此，第一连接部19的轴向高度为h，转子2沿轴向的高度为H，且0.5H<h<H。第一连接部19的轴向高度如此设置，便于稳定地对分瓣的转子段进行支撑，避免转子支架在分瓣过程中发生变形。
请一并参阅图7至图14，本申请实施例还提供了一种电机分瓣方法，使用如前所述的任一种电机分瓣或组装装置对电机进行分瓣。电机包括同轴设置的第一回转体1和第二回转体2，第一回转体1和第二回转体2中的任一者为定子，第一回转体1和第二回转体2中的另一者为转子。为了便于描述，本申请实施例以内定子、外转子结构的电机为例进行说明。
该电机一般为预装配完成且试验合格的分瓣电机，尤其是包括预制分瓣定子、预制分瓣转子以及预制分瓣端盖的大直径电机。该电机分瓣方法包括：
步骤S1：将电机固定至第一拆分装置10；
步骤S2：通过套装装置30将第一回转体1与第二回转体2分离，并将第二回转体2固定至第二拆分装置20；
步骤S3：通过第二拆分装置20将第二回转体2进行分瓣，并通过第一拆分装置10将留置的第一回转体1进行分瓣。
本申请提供的一种电机分瓣方法，通过电机分瓣或组装装置的套装装置30将电机的第一回转体1与第二回转体2分离，通过第一拆分装置10将第一回转体1沿周向分瓣，通过第二拆分装置20将第二回转体2沿周向分瓣，各分瓣段连同拆分装置一起运输，有效解决了电机的道路运输超限、运输成本高的问题。其中，第一回转体1和第二回转体2中的任一者为定子，第一回转体1和第二回转体2中的另一者为转子。
如图11和图12所示，步骤S2中，通过套装装置30将第一回转体1与第二回转体2分离，并将第二回转体2固定至第二拆分装置20，包括：
步骤S21：将第一套装件31与第一回转体1连接，将第二套装件32与第二回转体2连接；
步骤S22：吊装第二套装件32沿第一套装件31的内壁或者外壁移动，以将第二回转体2与第一回转体1分离；
步骤S23：将第二回转体2固定至第二拆分装置20。
如图13所示，步骤S3中，通过第二拆分装置20将第二回转体2进行分瓣，包括：
步骤S31：将第二套装件32从第二回转体2拆离；
步骤S32：取下各相邻的第二可分离部201的第二连接部28之间的紧固件；
步骤S33：通过第二驱动设备50将各第二可分离部201分开，以将第二回转体2的各分瓣段固定于各第二可分离部201进行分瓣操作。
如图14所示，步骤S3中，通过第一拆分装置10将留置于第一拆分装 置10的第一回转体1进行分瓣，包括：
步骤S31’：将第一套装件31从第一回转体1拆离；
步骤S32’：取下各相邻的第一可分离部101的第一分离部之间的紧固件；
步骤S33’：通过第一驱动设备40将各第一可分离部101分开，以将第一回转体1的各分瓣段固定于各第一可分离部101进行分瓣操作。
另外，如图8至图10所示，步骤S2之前，即通过套装装置30将第一回转体1与第二回转体2分离，并将第二回转体2固定至第二拆分装置20之前，还包括：将电机的非电磁构件从电机拆离。
其中，非电磁构件包括电机的端盖4以及主轴3等大部件结构，其中，将端盖4从电机拆离后固定至第一拆分装置10，如图9所示。
进一步地，由于端盖4也是具有相当大的直径尺寸的圆形板件结构，步骤S3中，通过第一拆分装置10将留置的第一回转体1进行分瓣的同时，还包括：通过第一拆分装置10将端盖4进行分瓣。端盖4的具体分瓣方法如前所述，不再赘述。
主轴3的拆离，如图10所示，具体为将主轴3整体从第一拆分装置10吊离。由于主轴3位于电机的最内侧，其最大直径一般可以控制在运输限制尺寸以内，因此，将主轴3吊离后可直接整体运输。
另外，本申请实施例提供的电机分瓣方法还包括：
步骤S4：将分瓣后的各分瓣段与相应的第一拆分装置10或者第二拆分装置20一并分别运输至待装配目的地。
例如，第一回转体1的各分瓣段和端盖4的分瓣段与第一拆分装置10的第一可分离部101一起固定并运输至待装配的下一个目的地，将第二回转体2的各分瓣段与第二拆分装置20的第二可分离部201一起固定并运输至待装配的下一个目的地，主轴3通过其它固定装置运输至待装配目的地。
到达待装配目的地后，再将第一回转体1的分瓣段、第二回转体2的的分瓣段、主轴3及端盖4的的分瓣段分别组装为完整的电机。
参阅图15，本申请实施例还提供了一种电机的组装方法，其大致与该 电机的分瓣方法的主要步骤相反，具体可以为：
步骤R1：将第一回转体1的各分瓣段通过第一可分离部101组合形成第一拆分装置10而组装成完整的第一回转体1；将第二回转体2的各分瓣段通过第二可分离部201组合形成第二拆分装置20而组装成完整的第二回转体2；
其中，由于第一可分离部101与第二可分离部201为不同的装置，可以视情况同步进行。
步骤R2：将套装装置30分别固定至第一回转体1以及第二回转体2，并将第二回转体2吊离第二拆分装置20；
当以第一拆分装置10为主要固定结构组装完整电机时，将第二回转体2吊离第二拆分装置20，安装至第一回转体1；当以第二拆分装置20为主要固定结构组装完整电机时，将第一回转体1吊离第一拆分装置10，安装至第二回转体2。
步骤R3：通过套装装置30将第二回转体2与第一回转体1套装并固定，拆除套装装置30形成完整的包括第一回转体1以及第二回转体2的电机。最后将完整电机吊离第一拆分装置10。
需要说明的是，本申请仅以电机包括分瓣的定子1、分瓣的转子2以及分瓣的端盖4为例描述的分瓣拆分、组装及运输的方法，当然，电机的分瓣部件可以不限于上述定子1、转子2和端盖4，当存在其他的分瓣部件时，可按照本申请的分瓣、组装以及运输的构思进行合理扩展而得到相应的方法。
可以理解的是，上述电机分瓣方法及电机组装方法也适用于内转子、外内子结构的大直径电机的分瓣，不再赘述。
