Description

用于真空泵的塑料转子
技术领域
本发明涉及一种用于叶片泵的、特别用于真空泵的转子，该转子具有由塑料制成的可旋转驱动的基体，该基体在运行中围绕旋转轴线旋转，其中，该基体具有用于可滑动地容纳泵叶片的引导部，且其中，第一轴支承部位和第二轴支承部位在旋转轴线的方向上位于该基体两侧。此外，本发明还涉及一种叶片泵，特别涉及包括这样的转子的真空泵。
背景技术
在现有技术中已知用于叶片泵的转子。这样的转子通常具有圆柱形的引导部，其具有至少一个用于可滑动地容纳泵叶片的叶片井，其中，在引导部的两侧上分别设置圆柱形的轴支承部位，其被容纳在泵壳体的相应与其对应的支承凹槽中，使得转子在泵壳体中可旋转地被支承。在引导部的区域中，这样的转子外径大于在轴支承部位的区域中的外径，使得在引导部与轴支承部位之间设置轴倒棱，该轴倒棱也可用作在泵壳体的支承凹槽中的挡块。例如也在DE102012210 048 A1中已知这样的转子。
用于叶片泵的转子通常由金属制成，其中，转子被浇注有无益的形状。然而此外也已知，可在塑料压铸法中制造用于叶片泵的转子。然而在由塑料制成的转子中示出，转子的基体的实心实施方式可导致形成缩孔。为了避免形成缩孔，在现有技术中已知，在引导部的圆环形式的轴倒棱中在基体中设置凹槽，引导部的直径大于轴支承部位的直径。然而，这样的凹槽仅可在相对短的转子的情况下以相对大的直径或相对大的轴倒棱实现。然而，在相对长的转子的情况下，以相对小的直径实现所述做法是有问题的，因为引导部和轴支承部位的的不同的直径不适合构建足够大的凹槽。
发明内容
因此，本发明的目的在于，提供一种用于叶片泵的、特别用于真空泵的塑料转子，在其中，可简单且可靠地防止形成缩孔。
该目的通过具有权利要求1的特征的、用于叶片泵的转子实现。该转子的特征在于，第二轴支承部位具有位于与旋转轴线同心布置的圆形轨道上的、相互间隔的支承部分。第二轴支承部位的该分段构造证明是特别有利的，因为凹槽的布置不仅在圆环类形式的轴倒棱的区域中是可行的。
因此，当基体具有从第二轴支承部位开始沿着旋转轴线延伸的凹槽时是特别优选的。有利地，凹槽这样地被构建成圆柱形或大致圆柱形的，即，压铸模可简单成形。此外下述情况证明是特别有利的，即，当凹槽径向延伸直至进入第二轴支承部位。如通常地，转子的基体在引导部的区域中具有叶片井，在两个面之间的叶片可滑动地容纳在该叶片井，其中，引导部优选被构建成圆柱形的。
有利地，第二轴支承部位具有两个相互径向对置的圆弧部分，该圆弧部分在径向外侧分别具有支承部分。在此下述情况是特别优选的，即，当圆弧部分分别被两个平行于引导部的叶片井布置的平面限制，且其被限制到与圆形轨道同心布置的支承部分上。
此外下述情况是有利的，即，当第二轴支承部位在圆弧部分之间分别具有至少一个、优选两个接片部分时，该接片部分在其自由端上具有支承部分。通过设置在圆弧部分之间布置的接片部分，可额外于圆弧部分的支承部分实现对第二轴支承部位的另一径向引导，其中，在梁之间可设置更大的凹槽。
在转子的另一有利扩展方案中提出，第二轴支承部位被构建成圆柱形的。因为支承部分被布置在圆形轨道上，第二轴支承部位的包络面(Umhuellende)在转子运行中、即在围绕旋转轴线旋转时被构建成圆柱形的。此外下述情况是特别有利的，即，第一轴支承部位被构建成圆柱形。由此，用于支承转子的第一和第二轴支承部位可被容纳在泵壳体的圆柱形凹槽中。
转子的另一有利设计方案提出，转子具有与旋转轴线同心布置的孔，该孔在端面通入第一轴支承部位中，且引导部具有叶片井，其中，孔与叶片井流体连接。通过设置与旋转轴线同心布置的、与叶片井流体连接的孔，可提供用于润滑泵叶片的供油。
转子的一个特别有利的扩展方案提出，具有扭矩传递部分的金属插入件在第一轴支承部位的区域中被形锁合地插入基体中。在此下述情况是特别有利的，即，插入件被基体的塑料挤压包封。通过设置具有扭矩传递部分的插入件，诸如皮带传动的或电动机的驱动单元的旋转运动可被传递到泵转子上。
为了可靠地将旋转运动传递到泵转子上，下述情况是有利的，即，插入件与旋转轴线同心地被布置。
为了形锁合地连接插入件与基体，下述情况是有利的，即，插入件被构建成圆柱形的且在其外周侧上具有齿部时。此外下述情况是特别有利的，即，基体具有与齿部对应的对齿部。有利地，基体的该对齿部通过插入件的挤压包封被制造。
在转子的一个特别有利的实施方式中，齿部被这样地构建成燕尾形式的，即，齿部的齿径向向外扩张。齿部的齿的该燕尾形式的扩张是有利的，因为在泵转子运行中可避免由塑料制成的基体张开。此外，基体可被拉到金属插入件上。
下述情况证明是特别有利的，即，插入件由烧结钢、由钢或由黄铜制成。
此外可设想，扭矩传递部分是内六角或两平面。然而也可设想使用扭矩传递的其他可能性或其他横截面。
上述目的也通过具有权利要求13的特征的叶片泵、特别通过真空泵实现。

图7为在观察第二轴支承部位时的根据图1至3的泵转子的侧视图。
具体实施方式
图1示出用于在附图中未示出的叶片泵的、特别用于真空泵的泵转子10。在附图中，相同的构件和部件以相同的参考标记表示。泵转子10具有由塑料制成的基体12，该基体在运行中围绕旋转轴线14旋转。基体12具有引导部16，该引导部具有用于可滑动地容纳泵叶片的叶片井18。在此，叶片井18被两个平行的面20、22限制，其提供针对泵叶片的引导。
在旋转轴线14的方向上，第一轴支承部位24和第二轴支承部位26位于引导部16两侧，其中，引导部16的直径大于第一轴支承部位24的直径，使得在第一轴支承部位24与引导部16之间布置轴倒棱28。第一轴支承部位24被构建成圆柱形的。第一轴支承部位24和第二轴支承部位26这样地被构建，即，其可被容纳在未示出的泵壳体的圆柱形轴承容纳部中。
基体12是可旋转驱动的，且对此在第一轴支承部位24的区域中具有由烧结金属或黄铜制成的金属插入件30，其与旋转轴线14同心地被布置。在根据图2的分解图中可清楚地看到金属插入件30。该插入件30具有六边形的扭矩传递部分32，其可在图5和6中清楚地看到。通过设置扭矩传递部分32，诸如皮带传动或电动机的驱动单元的旋转运动可被传递到泵转子10上。
为了将扭矩从插入件30传递到基体12上，插入件30形锁合地被插入基体12中。特别地，插入件30被基体的塑料挤压包封。为了将扭矩传递到基体12上，插入件30在其外周侧34上具有可在图3、5和6中清楚看到的齿部36。通过挤压包封插入件30，基体12具有对应于齿部36的对齿部38，其同样可在图3、5和6中清楚地看到。在此，图5示出通过在垂直于泵转子10的旋转轴线14平面中的泵转子10的截面，其中，图6示出根据图5的截面的细节图VI。
插入件30的齿部36被构建成燕尾形式的，且具有多个齿40。特别地，齿部36这样地被构架成燕尾形式的，即，齿部36的齿40径向向外，即，垂直于旋转轴线14扩张。在此，齿40的侧面42与齿中间面44形成角度46。齿40的该燕尾形式的扩张是有利的，因为在泵转子10运行中可防止由塑料制成的基体12张开。
图3示出在观察第二轴支承部位26时的根据图1和2的泵转子10的斜视图。
图4示出通过根据图3的平面IV的通过泵转子10的截面，其中，图7示出在图3中所示的箭头48的方向上观察第二轴支承部位26时泵转子10的侧视图。
如可在图7中清楚看到的，第二轴支承部位26具有位于与旋转轴线14同心布置的圆形轨道上的、相互间隔的支承部分50。在此如可在图3中清楚看到的，第二轴支承部位26被构建成圆柱形的。现在当泵转子10在运行中在箭头52的方向上旋转时，形成第二轴支承部位26的包络面，其被构建成圆柱形的。
第二轴支承部位26具有两个相互径向对置的圆弧部分54，其径向向外分别具有支承部分50。圆弧部分54被两个平行于叶片井18布置的面56、58限制且被限制在与圆形轨道同心布置的支承部分50上。在根据图7的视图中可清楚地看到圆弧部分54。
在圆弧部分54之间分别布置两个接片部分60、62，其在其自由端上同样具有支承部分50。通过设置在圆弧部分54之间布置的接片部分60、62，可额外于圆弧部分54的支承部分50对第二轴支承部位26进行另外的径向引导。
因此，第二轴支承部位26被分段地构建成具有圆弧部分54和接片部分60、62，因为位于圆形轨道上的支承部分50相互间隔。第二轴支承部位26的该分段的构建证明是特别有利的，因为在圆弧部分54与接片部分60、62之间可在基体12中布置凹槽64。
如可在根据图4的截面中清楚看到的，在此凹槽64延伸几乎直至在第一轴支承部位24的区域中的轴倒棱28且被构建成大致圆柱形的，其中，在附图中设置不能看到的成形斜面，其使得可成形压铸工具。额外于凹槽64，在第二轴支承部位26的圆弧部分54中还布置凹槽66，然而其仅延伸通过第一轴支承部位26。
由于凹槽64、66，基体12可在压铸法中被压铸具有尽可能恒定的壁厚，且尽可能地或大致尽可能地避免形成缩孔。
如可根据图4的截面中清楚看到的，泵转子10具有与旋转轴线14同心布置的盲孔68，该盲孔在端面通入第一轴支承部位24中，且与叶片井18这样地流体连接，即，可提供用于润滑在叶片井18中滑动布置的泵叶片的供油。
