Description
技术领域
本发明涉及旋转机器。它涉及根据权利要求1的前序部分的凸极电机。
背景技术
垂直轴水力发电机在本领域中是众所周知的。
文献EP 0 740 402 A1涉及一种垂直轴水力发电机,其具有转子星,该转子星设有毂,并且在其外周边上布置有转子轮缘,该转子轮缘承载由极板层叠的转子极和极线圈,以及定子,定子围绕转子,通过气隙与后者隔开,并且具有由板层叠的定子板体,并且在内周边处具有用于容纳定子绕组的槽,定子绕组具有定子绕组端部和在板体的两个端面处的绕组连接,转子轮缘和定子板体两者都具有沿径向延伸的冷却狭缝,冷却空气可通过该冷却狭缝从毂穿过转子轮缘中的所述狭缝、两极之间的距离、气隙和定子板体中的狭缝进入围绕后者并配备有冷却器的环形空间并从那里返回到毂,转子本身用作冷却空气的输送和压力产生装置。
如图1中所示,其是EP 0 740 402 A1的图2的一部分,现有技术的转子构造包括转子毂(未示出),倾斜辐条从该转子毂辐射(radiate),其在顶部和底部处由覆盖环覆盖。这些构件形成转子星。转子轮缘10布置在其外周边处。其由板段11构成,板段11在周向方向上以交错的方式一层叠在另一层顶部上。在此布置中,层的相邻板段11彼此远离,使得获得多个沿径向延伸的冷却狭缝12,其完全穿过转子轮缘,并且冷却空气可沿箭头方向通过冷却狭缝沿径向流动到外部。倾斜臂和转子轮缘10之间的机械连接以已知的方式由条带13、楔形物14和在转子轮缘10的内周边处的轴向槽15制成。在外周边处,转子轮缘10具有沿轴向延伸的燕尾槽,用于紧固转子极17,转子极17设有相应形成的燕尾极爪16。转子极17承载极绕组18。在每种情况下,转子轮缘10中的径向冷却狭缝12通向两个相邻的转子极17之间的空间,即所谓的极间隙19。
在该机器中使用的设计具有一个主要缺点:接收凸极的极爪的转子轮缘中的极爪槽削弱轮缘,并产生一个固定负载质量,这必须由轮缘的其余部分维持,忽视了极槽和螺栓孔 (在层叠轮缘的情况下)。
消除轮缘中的极爪槽,这使得轮缘更弱,并且产生一个固定负载质量,其必须由轮缘的其余部分维持,忽视了极槽和螺栓孔(在层叠轮缘的情况下)。
发明内容
本发明的目的是提供一种凸极电机,它避免了已知机器的缺点,并且特别是在其轮缘处加强转子。
该目的通过根据权利要求1的凸极电机获得。
根据本发明的凸极电机包括绕机器轴线旋转的转子,所述转子在其圆周上具有带有预定外半径的转子轮缘,由此多个凸极(每个凸极沿径向方向延伸)在相应极-轮缘界面处的所述转子轮缘处附接到所述转子。
其特征在于,在所述极-轮缘界面处,多个轴向肋状轮缘延伸部从所述转子轮缘沿径向突出,具有在相邻轮缘延伸部之间的预定的周向距离,每个凸极具有多个轴向极凹槽,其匹配和接收相应的极-轮缘界面处的所述肋状轮缘延伸部,并且提供固定元件以将所述肋状轮缘延伸部固定在所述极凹槽中。
根据本发明的一个实施例,所述固定元件布置在所述转子轮缘的外侧。
特别地,所述固定元件可沿轴向方向延伸并施加。
此外,所述固定元件可布置在所述极凹槽和其侧壁处的所述肋状轮缘延伸部之间的相应界面孔中。
特别地,所述固定元件可为轴向固定销。
所述固定销可为具有圆形横截面的剪切销。
所述固定销可构造为膨胀销,其消除了其界面孔的径向间隙。
所述固定销可构造为开口销。
特别地,所述固定销可劈开成两部分并具有鳄鱼锥形界面。
固定销的数量及其位置是机械尺寸的结果,这意味着销不必沿极到轮缘的界面表面均匀地分布。
相同的适用于销的大小,其在每个界面点上不需要相同。
附图说明
现在借助于不同实施例且参照附图来更详细阐释本发明。
图1示出了凸极电机转子的详细透视图,该凸极电机转子具有根据现有技术通过极爪附接的凸极;
图2以截面轴向视图示出了根据本发明的一个实施例的极附接件;以及
图3示出了图2的附接区域的放大视图。
具体实施方式
在现有技术中,凸极电机上的极要么使用称为"极爪"的极体延伸部固定到转子轮缘上,极爪是从极体向内突出到机器的元件,装配在转子轮缘槽上,要么它们通过螺栓固定,沿径向穿过转子轮缘和极的一部分。
根据本发明,使用其间的剪切销,极至轮缘连接(极-轮缘界面)通过最小高度连接系统优化,放置在极侧区域上。
根据这个想法,没有向内延伸的极爪或固定螺栓。转子轮缘自身向外突出到极体中,并且通过其间的剪切销完成固定。由于可沿径向完成极装配,这种解决方案还可帮助最小化极和轮缘之间的间隙,这有助于强地减小通过磁路的磁阻。
代替传统的现有技术解决方案,使用位于转子轮缘的外半径内的径向切割的槽,以及沿径向向内突出以将极芯固定在转子轮缘上的极爪,本锚定解决方案基本上在极芯区域中形成,使极固定从轮缘的外半径向外突出(并因此向内到极芯中)。
锚定系统或极-轮缘界面的一部分放置在极线圈的阴影下或下方。因此,为了移除极,在移除连接销之后,必须使用气隙空间稍微径向地滑动极,并然后使其沿轴向、平行于轮缘轴向长度滑动。
图2和3示出了本发明的实施例。
图2和3的凸极电机30包括转子20,转子20绕机器轴线(未示出)旋转。转子20在其圆周处具有转子轮缘28,转子轮缘28具有预定的外半径29。每个沿径向方向延伸并配备有极绕组23的多个凸极22在所述转子轮缘21处附接到所述转子20。每个极在极-轮缘界面24处锚定到所述转子轮缘21,极-轮缘界面24具有交错接合的特征。
在每个极-轮缘界面24处,多个轴向肋状轮缘延伸部25从转子轮缘21的圆柱形表面28沿径向突出,具有在相邻的轮缘延伸部25之间的预定的周向距离d。在另一侧上,每个凸极22具有多个轴向极凹槽26,其匹配并接收极-轮缘界面24的所述肋状轮缘延伸部25。
凸极22通过固定元件或固定销27以该交错接合的构造固定,固定元件或固定销27提供用于将所述肋状轮缘延伸部25固定在所述极凹槽26中。固定元件27布置在转子轮缘21的外侧。它们沿轴向方向延伸并施加。如图2和图3中所示,它们布置在所述极凹槽26和其侧壁处的所述肋状轮缘延伸部25之间的相应界面孔中。
根据该解决方案,由于这种从转子轮缘21延伸并装配到极22中的该肋状轮缘延伸部或肋25是可接近的,因此可移除销27并沿轴向滑动极22,而不从发电机定子内移除转子20。此外,由于没有向内延伸到轮缘21中的肋,转子轮缘21没有削弱,因此使用其径向强度的100%。
因此,转子轮缘21上的极固定通过轴向销完成。为了在相邻表面或极和转子轮缘之间具有完美的接触,可考虑不同的可能性作为基本构想的变型。一种可能的固定方法是在引入固定销27之前沿轴向铰孔。
根据另一种解决方案,可使用膨胀销,其消除了界面孔的径向间隙。
根据此极设计,所提出的新锚定系统可或多或少地在凸极22的极芯内部穿透并且在极绕组23的区域下具有显著区域。在此情况下,一个另外的变型是将固定销27劈开成两部分,优选地具有鳄鱼锥形界面。
在凸极22在转子轮缘21上沿径向向内滑动之后,开口销应旋转,并且然后沿轴向驱动以彼此相对锁定。
本发明内的另一个变型是极固定可要么垂直于轮缘界面(圆柱表面28)要么具有梯形形状,由此该角度将便于极22的拆卸和移除。
固定销27的数量和它们在极-轮缘界面24中的位置由机械尺寸确定,即固定销27不必沿极到轮缘的界面表面均匀地分布。相同的适用于销的大小,其在每个界面点上不需要相同。
本发明具有各种优点:
•对于效率不是关键问题的机器,可优化效益。初步分析表明,可实现具有相同或更好性能的较轻机器。
•此外,可提高临界速度。
•该解决方案的另一个优点是,由于它们不需要称为"极爪"的延伸部,所以较少原材料用于极。
•另一个优点是在接触区域中具有大的半径,从而优化了应力集中,并从而优化了极的疲劳寿命。
•使用剪切销的一个优点在于它们将有助于将转子轮缘中的负载与轮缘螺栓一起传递;因此,由于这种新功能,轮缘可甚至更加优化。
•由于在该解决方案中不需要使极爪滑过轮缘,因此另一个优点将是减少极和轮缘之间的安装间隙,这对磁路非常有利,因为它减小了磁路的磁阻。
•可沿轴向移除极,而无需从机器或发电机定子内移除转子。
•由于没有肋向内延伸到轮缘中,因此转子轮缘不会削弱,因此使用其径向强度的100%。
•通过不同方式冷却机器是在本发明的范围内,例如利用通过转子轮缘的径向通风冷却,或利用轴向冷却(在叶片/风扇的帮助下,促进沿轴向通过机器转子极和定子泵送空气)。
