Description
技术领域
本发明涉及一种轴承组件。此外,本发明涉及一种用于调节轴承间隙的调节螺钉。
背景技术
实践中已知具有多个轴承段的轴承组件。特别地,已知滑动轴承组件具有多个滑动轴承段。滑动轴承段可以是轴向滑动轴承段或径向滑动轴承段。轴承组件的滑动轴承段优选地紧固到壳体上,或者替代地紧固到转子上。每个滑动轴承段包括滑动轴承体,该滑动轴承体将自身支撑在优选地为转子或替代地为壳体的部件部段的滑动表面上。在滑动轴承体与滑动表面之间需要限定的轴承间隙,在实践中已知的轴承组件中,该轴承间隙可以通过组件垫片来调节。利用这种组装垫片来调节轴承间隙是麻烦的,并且因此是耗时的。为此,必须经常安装和移除轴承段,以确定的轴承垫片的正确厚度。
发明内容
需要一种轴承组件,其中可以更容易地调节轴承间隙。从这一点出发,本发明基于创造一种新型轴承组件和用于调节轴承间隙的调节螺钉的目的。
这个目的通过根据权利要求1的轴承组件来解决。
根据本发明的轴承组件用于将转子安装在固定壳体中。轴承组件包括优选紧固到壳体的多个滑动轴承段,其中每个滑动轴承段包括滑动轴承体,该滑动轴承体自身支撑在优选为转子的部件部段的滑动表面上。
在每个滑动轴承段的区域中,相应滑动轴承体与相应部件部段的滑动表面之间的轴承间隙可通过调节螺钉调节,滑动轴承体自身支撑在相应部件部段的滑动表面上。
相应调节螺钉具有外螺纹,经由该外螺纹,调节螺钉可以拧入到优选地在壳体侧上具有内螺纹的凹部中。在外周边上,相应调节螺钉包括凹槽,该凹槽在两侧上由调节螺钉的部段轴向界定。
至少一个夹紧螺钉延伸穿过轴向界定调节螺钉的凹槽的调节螺钉的部段,并且因此也穿过凹槽,经由该夹紧螺钉,界定调节螺钉的凹槽的调节螺钉的部段可以被夹紧,因此,相应调节螺钉可以被锁定在相应凹部中。
在根据本发明的轴承组件中,通过相应调节螺钉在相应滑动轴承段的区域中调节轴承间隙。通过至少一个夹紧螺钉,相应调节螺钉可以被夹紧并因此被锁定。可以在短时间内进行轴承间隙的简单调节,无需多次安装和移除轴承体。用于调节相应轴承间隙的调节螺钉被锁定在其位置,即通过与相应调节螺钉相互作用的至少一个夹紧螺钉来锁定。
根据本发明的有利的进一步发展,相应夹紧螺钉延伸穿过在轴向限定调节螺钉的凹槽的相应调节螺钉的部段中的内孔,其中部段之一上的内孔被实施为无螺纹贯通内孔,而部分中的另一个上的内孔被实施为螺纹内孔。这允许将相应调节螺钉特别有利地夹紧在接纳相应调节螺钉的凹部中。
根据本发明的有利的进一步发展,相应夹紧螺钉延伸穿过轴向界定调节螺钉的凹槽的调节螺钉的部段,并且在凹槽的区域中,完全地与凹槽的凹槽基部间隔开地穿过凹槽。这也有利于将相应调节螺钉有利地夹紧在接纳相应调节螺钉的凹部中。
根据本发明的用于调节轴承间隙的调节螺钉在权利要求6中限定。
本发明的优选进一步发展从从属权利要求和以下描述中获得。
附图说明
通过附图更详细地解释了本发明的示例性实施例,但不限于此。附图示出了:
图1示出了根据本发明的穿过轴承组件的截面图;
图2以前视图示出了轴承组件的细节,即轴承间隙调节螺钉;和
图3以侧视图示出了图2的细节。
具体实施方式
本发明涉及一种用于将转子安装在固定壳体中的轴承组件以及一种用于调节轴承间隙的调节螺钉。
根据本发明的轴承组件尤其用于将风力涡轮机的转子安装在风力涡轮机的固定壳体中,即用于安装经由转子叶片驱动的风力涡轮机的所谓主转子。
图1示出了用于将转子1安装在壳体2中的轴承组件的提取图。
图1的轴承组件包括多个滑动轴承段3,在所示的示例性实施例中,滑动轴承段3实施为轴向滑动轴承段。本发明不限于轴向滑动轴承段,而是也可以采用径向滑动轴承段。
在图1的示例性实施例中,滑动轴承段3紧固到壳体2,使得图1的滑动轴承段3是壳体侧滑动轴承段。每个滑动轴承段3包括壳体侧安装件4,壳体安装件各自通过至少一个安装螺钉5紧固到壳体2。相应的安装件4容纳滑动轴承体6,该滑动轴承体6将其自身支撑在转子1的滑动表面7上。
与所示的示例性实施例相比,滑动轴承段可以是紧固到转子1的转子侧滑动轴承段,其中相应滑动轴承段的滑动体然后将其自身支撑在壳体的滑动表面上。
为了轴承组件的正确操作,重要的是调节相应滑动轴承段3的区域中的轴承间隙,其中轴承间隙由相应滑动轴承体6与滑动表面7之间的空隙限定,滑动轴承体6自身支撑在滑动表面7上。
调节螺钉8用于调节该轴承间隙。在每个滑动轴承段3的区域中,相应滑动轴承体6与滑动表面7之间的相应轴承间隙可各自通过至少一个调节螺钉8调节,滑动轴承体6自身支撑在滑动表面7上。
相应调节螺钉8接纳在相应滑动轴承段3的安装件4的相应凹部9中。
这里,相应调节螺钉8具有外螺纹10,外螺纹10与接纳相应调节螺钉8的凹部9的内螺纹11相互作用。通过相应调节螺钉8的外螺纹10与相应凹部9的内螺纹11相互作用,调节螺钉8可以拧入相应滑动轴承段3的安装件4的凹部9中,以便因此调节滑动轴承体6与滑动表面7之间的空隙,滑动轴承体6自身支撑在滑动表面7上。
在相应调节螺钉8的外周边上,相应调节螺钉8包括凹槽12,该凹槽12在两侧上由调节螺钉8的部段13、14轴向界定,部段13、14相对于凹槽12径向突出。因此,调节螺钉8的外螺纹10在凹槽12的区域中断。在两个轴向侧上,调节螺钉8的凹槽12由调节螺钉8的部段13和14界定。在内侧,调节螺钉8的凹槽12由调节螺钉的凹槽基部15限定。
至少一个夹紧螺钉16延伸穿过轴向界定凹槽12的调节螺钉8的部段13、14,并且因此也穿过凹槽12。优选地,对于每个调节螺钉8,存在至少两个、优选至少四个、特别优选至少六个这样的夹紧螺钉16。
通过夹紧螺钉16,轴向界定调节螺钉8的凹槽12的调节螺钉8的部段13、14可以向着彼此夹紧,因此,调节螺钉8然后被锁定在接纳调节螺钉8的相应滑动轴承3的安装件4的相应凹部9中,相应凹部9也接纳相应滑动轴承体6。在操作过程中,相应调节螺钉8则不再会意外松脱,而是相应调节螺钉8被夹紧螺钉16锁定在其位置上。
夹紧螺钉16的纵向中心轴线平行于相应调节螺钉8的纵向中心轴线延伸。相应夹紧螺钉16延伸穿过相应调节螺钉8的部段13、14中的内孔17、18。带有内孔17、18的这些部段13、14也是轴向界定凹槽12的那些部段。相应夹紧螺钉16延伸穿过调节螺钉8的这些部段13、14,并且在凹槽12的区域中,完全地与凹槽12的凹槽基部15径向间隔开地穿过凹槽12。
用于夹紧螺钉16的内孔17、18在调节螺钉8的部段之一上,即在所示的示例性实施例中的部段17上,实施为螺纹内孔,而在调节螺钉8的另一部段14上实施为无螺纹贯通内孔。
然后,相应夹紧螺钉16在延伸穿过无螺纹贯通内孔的部段上没有任何外螺纹,但是相应夹紧螺钉16在接合在螺纹内孔中的特定部部段上具有外螺纹。相应夹紧螺钉16通过螺钉头19自身支撑在相应调节螺钉8上,即支撑在调节螺钉8的轴向表面上。
因此利用本发明,可以在具有滑动轴承段的轴承组件上容易且舒适地调节轴承间隙。为此,每个滑动轴承段3使用至少一个调节螺钉8,该调节螺钉8具有外螺纹10,并且经由该外螺纹10可以拧入相应滑动轴承段3的安装件4中的凹部9中,在该凹部9上形成对应的内螺纹11。这里,调节螺钉8在其外周向表面上包括凹槽12,凹槽12中断外螺纹10,并因此形成轴向界定凹槽12的两个部段13和14。在内侧,凹槽12由凹槽基部15界定。该夹紧螺钉16或每个夹紧螺钉16用于夹紧夹紧螺钉8的部段13和14,以便锁定它们以防止无意地变松。相应夹紧螺钉16完全地延伸穿过轴向界定凹槽12的部段13,然而不穿过位于部段13之间的调节螺钉的中间部段20,该中间部段20限定凹槽12的凹槽基部15。
为了调节轴承间隙,调节螺钉8因此被拧入滑动轴承段3的安装件4的相应凹部9中的限定位置。在此过程中,通过拧紧夹紧螺钉16,相对于凹部9的内螺纹11,调节螺钉8的外螺纹10的侧面间隙被完全消除。最初,夹紧螺钉只拧紧到消除该侧面间隙的程度,但是调节螺钉8仍然可以转动。因此,可以防止调节后的轴承间隙受到侧部间隙的影响和叠加。
通过进一步转动调节螺钉8来调节轴承间隙。一旦调节了轴承间隙,夹紧螺钉16就以限定的标称扭矩拧紧,并因此调节螺钉8最终锁定在其位置上,使得调节螺钉8不能再转动。
如果螺纹10的侧面间隙没有消除,则存在调节后的轴承间隙由于调节螺钉8夹紧而以侧面间隙的数量级改变的风险。
