Description

轴承压缩带
技术领域
本发明涉及轴承环，并且更特别地涉及用于轴承环的拉紧装置。所述装置提供朝所述轴承环的旋转中心的周向分布力。
背景技术

大轴承的问题是随着轴被加载，轴承环12可能扭曲。
发明内容
本发明通过施加朝向所述轴承环的旋转中心的周向分布力18来解决该问题。
根据一个方面，本发明提供用于轴承环的拉紧装置，包括带和拉紧器。带包括在每一端的连接器，并且拉紧器包括用于连接至连接器的装置。拉紧器还包括用于向带施加拉力的装置。在使用中，带被布置在轴承环周围并且带的接触轴承环的周长被减小，由此向轴承环施加压缩力。

具体实施方式
现在参照图1B，其示出了拉紧装置100的概念示意图，带108的第一端A和第二端B被连接到拉紧器105。所述拉紧器包括用于向带施加拉力的装置15。带的一端B被连接到所述拉紧装置，并且所述拉紧装置拉动端B进入缩短所述带的拉紧器105。当所述拉紧装置被布置在轴承环(未示出)周围时，拉紧器的持续驱动绷紧并且拉伸所述带并且增加所述带108中的拉力并且因此朝轴承环的旋转中心引入压缩力。引入到所述带中的所述拉力取决于所述轴承的尺寸及其应用：对于较小的轴承其值通常大于25kN，对于中等尺寸的轴承其值通常大于50kN，并且对于较大的轴承在75kN以上。
现在参照图2，其示出用于轴承环的拉紧装置，带108被连接到拉紧器105。所述带具有在每一端或其附近的连接器，并且在示出的示例中，所述带是钢丝绳并且所述连接器包括在绳108终端(分别在A和B)上的型锻(swaged)螺柱或按钮106a、110a。在钢丝绳一端(B)的螺柱110a包括螺纹。另一个螺柱106a是平面的具有大于绳的直径。这些连接到拉紧器105。拉紧器105包括安装板104。所述拉紧装置被示为安装于轴承环102。
现在参照图2至图8，其示出图1的拉紧装置的其它视图，所述带装置108包括所述平面螺柱106a的一端(A)被锚固于安装板104中的槽106b中。如可以在图4中看到的，所述带108的另一端(B)经过所述连接器110a的外部部分。拉紧器105包括安装板104，其包括通道或孔110b(以虚线示出)并且所述带108包括螺纹螺柱110a的一端(B)穿过所述通道110b并且通过与螺母112接合而紧固至所述安装板104。包括所述螺纹螺柱110a、所述安装板104和所述螺母112的所述拉紧器105随着螺母被绷紧而操作成拉动带108穿过安装板104。单独的工具通常绷紧所述螺母，由此增加带中的拉力。因为带在另一端(A)通过在槽106b中的连接器106a被锚固，这意味着布置在轴承环102周围的带108的长度被减小。因此绳108中的拉力被增加并且因此朝轴承环的旋转中心的压缩力被增加。当轴被加载时，压缩力足够防止轴承环扭曲。安装板104被设计能够使用螺栓拉紧设备来方便绷紧过程。在使用中，安装板104可以接触轴承环102。
带100被安装于轴承环102，或者轴承环的部件壳体。轴承环102，或者轴承环的部件壳体，是已经存在的部件并且不是本发明的一部分。拉紧力被施加到带，其避免了由轴承环提供的空间在使用中扭曲。
在图2至图8中示出的本发明的示例中，所述带部件108包括一个或多个构件，诸如所示出的绳，并且这些构件在使用中围绕所述轴承环102的圆周。此外，连接器106a被示出为经由槽106b连接至安装板104。技术人员应当理解同样的总体效果将通过直接地并且永久地连接所述安装板至所述带108的一端来实现。
现在参照图9和10，其分别以等距视图和侧视图示出拉力器装置的另一个示例，带部件108被连接到拉紧器105。带部件具有在每一端的连接器，并且在示出的示例中，带部件包括在如上文描述的绳108的一端(B)上的型锻(swaged)螺柱110a。在该示例中，在带部件108的另一端(A)的连接器由形成在带部件中的环122提供，其中带部件的终端成环并且由锚120锚固到所述带部件。所述环122被安装在安装板104的周围并且由通道(见下文)保持在适当位置。在使用中，安装板104可以接触轴承环102。在该视图中还示出封套130，在带组件附接到轴承期间，拉紧设备将占用所述封套130。如上文所描述的，带由绷紧螺母112拉紧。
现在参照图11A-D，其示出安装板104的其它视图，通道132、134和136被形成在拉紧器105中，其用于保持带部件在适当位置并且还防止由所述拉紧器中的尖锐边缘在带部件被拉紧时对带造成伤害。如在图11D中特别示出，通道110b穿过拉紧器105。
带100可以在轴承被附接到其它机器部件之前或之后被安装。
在描述的实施例中，当被拉紧时，拉紧装置被保持在轴承环的适当位置；安装装置不是必要的。
在进一步的实施例中，拉紧装置包括保持器以用来将绳定位在轴承环的圆周上。如果带部件将要断裂，这些保持器用来保持安装板并且进一步防止缆绳从轴承环掉落。
尽管在示例中示出的带部件108包括绳，其它适当的带部件108可以例如包括链或条。
类似地，用于施加拉力的装置可以例如包括棘轮或齿轮。
棘轮拉紧器是众所周知的，并且图12中示出典型的棘轮拉紧器1200。它包括线轴1210、棘轮和相关联的齿轮1230以及把手1220，并且是通常被用来绷紧带108的机械装置，。
其它的带/拉紧器装置包括软管夹、T型螺栓夹，以及具有预先形成的孔和带扣的带。
在另一个示例中，公开了包括所述拉紧装置的风力涡轮机轴承。特别地，所述拉紧装置被接合围绕位于叶片和转子毂之间的叶片桨距轴承的外周界，并且由钢支架104保持在适当位置。这向轴承引入压缩力，其减小了在轴承环中的张应力并且提高了桨距轴承的寿命。
