Description

一种在风力涡轮机的轴和风力涡轮机轴承组件上安装滚动轴承的方法
技术领域
本发明涉及风力涡轮机中的轴承组件。更明确的是，本发明涉及一种在风力涡轮机中的转子轴上安装滚动轴承的方法和轴承组件设计。
背景技术
用于风力涡轮机的一种经常使用的设计是使用一转子轴以连接风力涡轮机的转子至发电机，从而将旋转能量传递至发电机，其进而产生电力。转子轴由至少一个或者两个轴承支撑。这些轴承可以安装在转子轴上的锥形座上，其中，此类轴承的内孔呈现一相应的截头圆锥形轮廓。为了便于此类轴承的安装，经由转子轴上的钻孔，将油压入轴承与转子轴的接触表面之间，其中，钻孔在转子轴的锥形安装座处截止。
发明内容
本发明的发明人已经发现在转子轴上的此类钻孔可以减小轴的强度。因此，已经认识到的是，有必要提出一种新的方法和设计以避免当前设计所暴露的缺陷。
因此，本发明的目的是提出一种可避免现有技术中至少一个缺陷的新的方法和设计，并且具体地，其导致一种风力涡轮机以及其转子轴强度增加的设计。通过如在独立权利要求中所限定的方法以及轴承组件已经实现了此目的。
根据第一方面，通过一种在风力涡轮机的转子轴上安装滚动轴承的方法来实现此目的，其中，轴承呈现外圈、内圈以及插入两圈之间的滚动元件，并且其中，内圈呈现一内圆周表面，此表面呈现出截头圆锥形轮廓。通过截头圆锥形轮廓，滚动轴承被安装在转子轴上的相应的锥形座上。此方法包括下述步骤：
将液体压入内圈的内圆周表面与锥形座之间，从而便于推动锥形座上滚动轴承，
通过作用在滚动轴承上的轴向力，推动锥形座上的滚动轴承，
其中，在内圆周表面的轴向端部，将液体压入两表面之间。
此方法的优点是不必在风力涡轮机的转子轴上钻孔。这将导致此轴与具有钻孔的轴相比有提高的强度。风力涡轮机转子组件有刚性以及坚固的设计是很重要的，从而避免了不必要的维护和修理工作。转子组件安装到风力涡轮机的机舱内，其位于地面水平之上的高处。因此，修理工作和维护成本高，也难以进行。
在该方法的一实施例中，液体是油、合成油或者其他非腐蚀性流体中的任一种。
在该方法的一实施例中，一圈安装在轴上并且其位于与内圈的轴向端部相邻并接触，其中，经由圈中的管道，液体被压入两表面之间，此管道靠近内圆周表面的轴向端部截止。
根据本发明的第二方面，通过一种风力涡轮机轴承组件来实现此目的，此风力涡轮机的轴承组件包括：
转子轴，
滚动轴承，其中滚动轴承呈现外圈，内圈以及插入两圈之间的滚动元件，并且其中内圈呈现一内圆周表面，此表面呈现一截头圆锥形轮廓，并且其中，通过截头圆锥形内圆周表面，此滚动轴承安装在转子轴上的相应的锥形座上。此轴承组件还包括安装在轴上并在滚动轴承的轴向端部至少与内圈接触的第一圈，并且其中，第一圈还呈现一管道，其中管道靠近内圆周表面的轴向端部截止。
此设计的优点是不必在风力涡轮机的转子轴上钻孔。取而代之的是曲径圈中的管道，此处诸如油的液体将被压入内圈与轴之间。这将导致此轴与具有钻孔的轴相比有提高的强度。风力涡轮机转子组件有刚度以及坚固的设计是很重要的，从而避免了不必要的维护和修理工作。此转子组件安装在风力涡轮机的机舱内，其位于地面水平之上的高处。因此，修理工作和维护成本高，也难以进行。
第一方面的所有实施例适用于第二方面的所有实施例，并且反之亦然。
在本发明的一实施例中，第一圈是曲径圈，其中，在滚动轴承的轴向端部，此曲径圈至少与内圈以及外圈接触，并且其中，此曲径圈封堵外圈与内圈之间的空间。在另一实施例中，第一圈是轴承座的环形部分、密封件或轴承内圈定位装置或者任何其他适合的圈中的任一种。
在一实施例中，滚动轴承是圆环滚子轴承、球面滚子轴承、圆锥滚子轴承、圆柱滚子轴承，或者用于风力涡轮机轴承组件的任何其他适合的滚动轴承中的任一种。在轴承组件的一实施例中，组件还呈现了安装在轴上并在滚动轴承的其他轴向端部与内圈和外圈接触的第二曲径圈，其中第二曲径圈封堵外圈与内圈之间的第二空间。
在轴承组件的一实施例中，组件包括安装在轴上并邻近第一曲径圈的第三圈，其中，第一曲径圈、第三圈以及轴配置成在围绕轴的圆周延伸中形成一圆周腔。
在轴承组件的一实施例中，此腔作为压力腔，用于通过轴向地推动在轴上的锥形座上的轴承来将轴承安装在轴上。
在轴承组件的一实施例中，轴呈现一圆周凹槽，并且其中，第三圈被轴向固定在介于第一曲径圈与凹槽中的金属丝之间的轴上。
附图说明
下文将对多个优选实施例的更加详细的说明进行描述。应该注意的是，所附附图未按比例绘制，并且在某些情况下，为了更好地解释本发明，具体的细节可被放大。此外，本发明如权利要求所述不限制于所描述和示出的实施例，而是在权利要求范围内，对于本领域的技术人员可以对其进行修改。
