具体实施方式
下面参照附图描述本发明的示例性实施方式。
如图1所示，本公开提供一种可自监测的滚动轴承组件，该滚动轴承组件包括滚动轴承1，滚动轴承1包括套圈和滚动体4，套圈包括固定套圈2和旋 转套圈3。例如，在图示的实施方式中，固定套圈2为外圈，旋转套圈3为内圈。
在未图示的其他实施例中，固定套圈2可以为内圈，旋转套圈3可以为外圈。
滚动轴承1还包括无线传感器7，无线传感器7安装于，例如粘接于滚动轴承1的固定套圈2和旋转套圈3。无线传感器7能够实时监测旋转套圈3和固定套圈2，无线传感器7不用外接电线，能够一边对旋转套圈3进行监测一边随旋转套圈3转动。
滚动轴承组件可以包括例如三个无线传感器7，两个无线传感器7设于固定套圈2，一个无线传感器7设于旋转套圈3。可以考虑避开轴承承载区、便于轴承安装、加强信号强度、降低加工成本和提高可行性几个方面并根据监测需要而确定无线传感器7的数量和位置。
多个无线传感器7可以设于同一套圈的不同的位置，从而实现不同位置的在线监控。
如图2至图7所示，滚动轴承1具有用于安装无线传感器7的装配槽5、6，装配槽5设于固定套圈2，装配槽6设于旋转套圈3。装配槽5、6设置成使无线传感器7安装于装配槽5、6时不超出滚动轴承1的轴向边界和径向边界，这样，无线传感器7基本不会影响滚动轴承1的安装。
装配槽5例如位于固定套圈2的背离滚动体4的外周面21上，例如外圈的外周面，无线传感器7可以沿径向R安装到装配槽5。这里，可以将装配槽5称为在套圈的周面上的装配槽。
装配槽5可以位于固定套圈2的外周面21的轴向边缘，装配槽5在固定套圈2的外周面21的轴向边缘处具有在滚动轴承1的轴向A上敞开的开口55，无线传感器7通过该开口55与外部设备通讯。
在其他实施方式中，装配槽5的位置可以变化，例如装配槽5可以位于固 定套圈2的外周面21的轴向A上的一半等，只要装配槽5具有在轴向A上敞开的开口55即可。
装配槽5的在轴向上敞开的开口55用作无线传感器7与外部通信的窗口，无线传感器7安装于装配槽5的同时能够与外部通信，从而实现了无线传感器7对滚动轴承1的固定套圈2的实时监测，且使得滚动轴承1的用于安装无线传感器7的部分结构简单，滚动轴承1更易于加工。
装配槽5具有定位特征，该定位特征能够在滚动轴承1的轴向A和周向C上定位无线传感器7，从而能够加强无线传感器7的定位，例如在无线传感器7粘接至滚动轴承1的基础上实现无线传感器7定位的双保险。
具体地，如图2所示，在第一实施例中，定位特征可以由装配槽5的槽侧壁51和设于槽侧壁51的凹部53形成。槽侧壁51用于在滚动轴承1的周向C上定位无线传感器7，凹部53用于在滚动轴承1的轴向A上定位无线传感器7。凹部53例如具有圆滑过渡的内表面。凹部53例如设于装配槽5的两个相对的槽侧壁51。
如图3所示，在第二实施例中，定位特征可以由装配槽5的槽侧壁51和设于装配槽5的槽底壁52的台阶54形成。台阶54可以位于装配槽5的轴向外端(装配槽5的在轴向A上远离套圈的轴向中心的那端)，装配槽5的轴向内端(装配槽5的在轴向A上靠近套圈的轴向中心的那端)设有槽侧壁51，槽侧壁51和台阶54一起在滚动轴承1的轴向A上定位无线传感器7。
如图4所示，在第三实施例中，定位特征可以由装配槽5的槽侧壁51形成，槽侧壁51的开口55的沿着周向C的宽度可以小于装配槽5的轴向内侧部分的沿着周向C的宽度，从而装配槽5具有开口收拢的形状。开口55可以位于装配槽5的轴向外端，装配槽5的轴向内端设有槽侧壁51，槽侧壁51和开口55一起在滚动轴承1的轴向A上定位无线传感器7。
如图5至图7所示，滚动轴承1包括位于旋转套圈3的装配槽6，装配槽6位于旋转套圈3的端面31，例如内圈的端面31，无线传感器7可以沿轴向A安装到装配槽6。这里，可以将装配槽6称为在套圈的端面上的装配槽。
装配槽6可以从旋转套圈3的端面31的径向内侧延伸至径向外侧，装配槽6在旋转套圈3的端面的径向边缘处具有在滚动轴承1的径向R上敞开的开口65。无线传感器7可以通过在径向R上向外敞开的开口65与外部设备通讯。
此外，无线传感器7还可以通过装配槽6在轴向A上未被例如旋转轴的轴肩遮挡的部分而与外部通讯。
应当理解，旋转套圈3的远离旋转轴侧具有滚动体4，滚动体4在轴向上通常短于旋转套圈3而且旋转套圈3的径向边缘通常具有倒角，从而设在旋转套圈3的端面的装配槽6具有在径向上向外敞开的开口65。
旋转套圈3的远离旋转轴侧的开口65为敞开的，而靠近旋转轴侧的开口65通常由旋转轴遮挡而不处于敞开状态。例如，当内圈用作旋转套圈3时，在径向内边缘的开口65通常被旋转轴遮挡而不处于敞开状态，在径向外边缘的开口65处于敞开状态。
在其他实施方式中，装配槽6的位置可以变化，例如装配槽6可以位于旋转套圈3的端面31的径向内侧半部或者径向外侧半部，只要装配槽6具有在径向R上敞开的开口65即可。
装配槽6的在径向R上敞开的开口65用作无线传感器7与外部通讯的窗口，无线传感器7安装于装配槽6的同时能够与外部通讯，从而实现了无线传感器7对滚动轴承1的旋转套圈3的实时监测，且使得滚动轴承1的用于安装无线传感器7的部分结构简单，滚动轴承1更易于加工。
旋转套圈3的装配槽6的定位特征与上述固定套圈2的装配槽5的定位特征相似，下面描述二者的区别之处。
如图5所示，在第一实施例中，定位特征由槽侧壁61和设于槽侧壁61的凹部63形成。槽侧壁61用于在滚动轴承1的周向C上定位无线传感器7，凹部63用于在滚动轴承1的径向R上定位无线传感器7。凹部63例如具有圆滑过渡的内表面。凹部63例如设于装配槽6的两个相对的槽侧壁61。
如图6所示，在第二实施例中，定位特征可以由槽侧壁61和设于装配槽6的槽底壁62的台阶64形成。台阶64例如可以位于装配槽6的径向两端从而用于在滚动轴承1的径向R上定位无线传感器7。
如图7所示，在第三实施例中，定位特征可以由装配槽6的槽侧壁61形成，槽侧壁61的开口65的沿着周向C的宽度可以小于装配槽6的径向中间部分的沿着周向C的宽度，从而装配槽6具有开口收拢的形状。装配槽6可以具有两个开口65，两个开口65位于装配槽6的径向两端从而槽侧壁61在两个开口65处在滚动轴承1的径向R上定位无线传感器7。
如图8所示，与具有凹部53、63的装配槽5、6安装的无线传感器7具有凸耳71，凸耳71与凹部53、63装配。与具有台阶54、64或者开口收拢形状的装配槽5、6安装的无线传感器7可以不具有上述凸耳71。
当然，上述多个实施方式的特征可以适当地组合。
滚动轴承组件还可以包括与固定套圈2安装的轴承座和与旋转套圈3安装的旋转轴。轴承座位于无线传感器7的径向外侧，从而在固定套圈2的径向R上定位无线传感器7。旋转轴，例如旋转轴的轴肩在旋转套圈3的轴向A上定位无线传感器7。
轴承座和旋转轴也能够在无线传感器7粘接至滚动轴承1的基础上加强无线传感器7的定位，实现无线传感器7定位的双保险。
上述无线传感器7包括例如温度传感器。
当然，本发明不限于上述实施方式，本领域技术人员在本发明的教导下 可以对本发明的上述实施方式做出各种变型，而不脱离本发明的范围。
