Abstract
本发明提出一种机械换流的电动机,它的电刷夹(8)构成在一个支承板(9)上,支承板用作电子线路板。支承板(9)具有一个带两个限定支脚(12,13)的缺口(11),两支脚具有用于容纳两个电刷(16,17)的彼此面对的凹口(14,15),凹口(14,15)的彼此面对的边缘构成导轨(18a,18b),导轨(18a,18b)***电刷(16,17)的相应导槽(19a,19b)中。在导轨(18a,18b)上具有导电的覆盖层(24),尤其是线路(10),覆盖层(24)用于插在凹口(14,15)中的电刷(16,17)的电接触。
Description
本发明涉及机械换流电动机。已经由WO84/00645公开了一种机械换流的电动机,为了夹持电刷,该电动机具有在支承板上构成的导轨,导轨***到刷的相应导槽中。该支承板设置来夹持总共二个电刷,电刷分别经过单独的绞合线形成电接触。
此外,DE4215446A公开了机械换流的电动机的一种电刷夹持装置,它具有设在一个线路板上的筒形刷架。通过与线路板的线路的单独连接实现刷的电接触。
本发明的机械换流的电动机,具有电刷夹(8),该电刷夹具有在至少一个支承板上构成的导轨,导轨分别成对地彼此平行延伸,其中,在每对导轨之间构成电刷的容纳口,并且导轨用于纵向地插在电刷的相应的导槽中,其特征在于,导轨为了与电刷的电接触,其外表面被作成导电的。相比之下它具有这样的优点,即不需要用于使电刷电接触的单独部件。也由此简化了电刷夹的结构。
通过在从属权利要求中所述的措施可以得到权利要求1中给出的电动机的优选实施形式。
在附图中描绘了本发明的两个实施例,对它们将在以下的描述中详细的说明。附图所示为:
图1构成电刷夹的线路板的正视图,
图2电刷夹的另一实施例。
图1中示出了用于电刷夹8的支承板9。该支承板9为线路板结构并在其上设有大量未示出的电子元件,它们彼此通过线路10连接。支承板9具有一个缺11,该缺口以两个支脚12,13为限界并大致形成矩形。在支脚12,13中开有朝着缺口11敞开的凹口14,15,例如是冲压出来的,凹口分别构成同样是矩形的、用于容纳电刷16,17的容纳口。凹口(14,15)的彼此面对的边缘区域分别构成导轨18a,18b,在电刷16,17被置入所属的容纳孔时,这些导轨嵌入电刷16,17的相应导槽19a,19b中。导轨18a,18b的间距的确定准则在于,分别有一个电刷16,17可在导轨18a、18b之间纵向移动地被容纳在凹口14,15中。
在图1的下半部中示出了一个被置入到所属凹口15中的电刷17。在电刷17与凹口15的底侧20之间放置着一个螺旋弹簧21,该弹簧朝着电动机的整流子22的方向以弹簧力向电刷加载,该整流子为转子结构并仅示出了其一部分。在图1的上半部中示出了***凹口14之前的电刷16。其中可以看出,在支承板9的凹口14的底侧20上具有一个用于螺旋弹簧21的导向凸出部23。
为了使电刷16,17进行电接触,导轨18a、18b上设有导电覆盖层24。特别有利的是,覆盖层24与线路10同时地覆盖在支承板9上。为此,覆盖层24由与线路10相同的材料、如铜制成。其中,电刷16,17的电接触通过导电的覆盖层24来实现。由于整流子22的旋转运动,使电刷16,17在导槽19中产生摆动,其摆动量相当于导轨18的导向间隙。因此,在覆盖层24及电刷16,17之间一直存在电接触。具有电刷夹8的支承板9大致放置在一个平面上,该平面是由整流子22的转动轴线25与垂直于该转动轴线25的垂线26构成的。然而原则上,该支承板9也可垂直于转动轴线25,即与转动轴线25错置90°地设置。例如为了容纳一个轴承,通过凹口11a使支承板9的缺口11径向扩大。
在图2中示出了弹簧21的第二实施例。其中,与第一实施例中相同及具有相同功能的部件用相同的标号表示。设置了一个大致为曲折形的弹性元件27来取代螺旋弹簧。该弹性元件的制造例如可以通过由普通的线路板材料、例如纤维增强的塑料作的支承板9中相应地冲出凹口14来实现。该弹性元件27可沿电刷16的移动方向变形并当电刷16***凹口14时被夹紧。在预计没有较大的电刷磨损及据此在电机的工作寿命中不出现大的弹簧行程的条件下,设置这样一种弹性元件27来代替螺旋弹簧是特别适宜的。
