Description

温度传感器轴承组件 技术领域
本发明涉及轴承技术领域。具体地，本发明涉及一种温度传感器轴承组件。
背景技术
众所周知，轴承间隙对轴承寿命有着至关重要的影响，而轴承的温度是影响轴承间隙的关键因素之一。因此，必须在轴承的设计和使用期间考虑轴承的实际工作温度。为了精确获取轴承的温度，需要在轴承圈上安装温度测量模块。传统的温度传感器通常需要连接信号传输线和供电线，因此必须安装在静止的轴承圈上。但是，对于某些特殊的应用场景，例如在某些变速器的行星齿轮组中，轴承的内圈和外圈同时转动，传统的测量手段就不再适用。
现有技术中使用安装在外壳上的热电偶来测量变速器轴承的温度，但这仅适用于支撑轴承，而不适用于行星齿轮轴承。已知的几种测量转动轴承部件的技术如下：
(1)红外温度传感器，其可以设置在轴承之外，对轴承的温度进行非接触式测量，但其测量对象必须保持静止，以防止测量点的变化；
(2)电滑环温度传感器，其可以借助电滑环来对安装在转动轴承部件上的传感器供电并输出测量信号，但其需要较大的安装空间且容易因磨损而影响使用寿命；
(3)装配有电池的无线温度传感器，其通过自身集成的电池来供电并无线地发送温度测量信号，但其同样需要较大的安装空间，同时还需要定期更换电池。
此外，还有一些新型的测量技术可以对转动轴承部件进行测量，但需要改变轴承部件的现有结构，因此在验证和生产方面成本较高。
发明内容
因此，本发明需要解决的技术问题是，提供一种能够在不改变现有轴承结构的情况下测量转动的轴承部件的温度的温度传感器轴承组件。
上述技术问题通过根据本发明的一种温度传感器轴承组件而得到解决。该温度传感器轴承组件包括能够相对转动的内转动件、外转动件以及安装在内转动件和外转动件中至少一者上的温度传感器模块，其中，该温度传感器模块是安装在内转动件和/或外转动件的轴向端面上的安装槽中的无线无源传感器模块。这里的转动件例如可以是标准设计的轴承内圈和轴承外圈，也可以是齿圈式外圈、锥形滚子轴承圈、圆柱滚子轴承圈、滚珠轴承圈或滑动轴承圈等。使用无线无源传感器模块来替代传统的温度传感器，可以免去为传感器提供电源的电源线和传输测量信号的信号线，因此可以将其直接安装在转动的轴承圈上，从而精确地测量轴承圈的温度。同时，这种温度传感器模块直接安装在转动件的轴向端面上的安装槽中，占用空间小，不需要对轴承的结构进行明显改变，更不会对轴承的结构强度造成影响，因此能够降低验证和生产成本并且适用范围广泛。
根据本发明的一个优选实施例，为了更好地利用现有的轴承结构，用于安装温度传感器模块的安装槽可以是温度传感器轴承组件上现有的润滑油槽或其他槽结构。通过这种方式，可以在完全不改变现有轴承结构的基础上安装温度传感器模块，最大限度地利用现有的轴承结构，从而使验证和生产成本降到最低。
根据本发明的另一优选实施例，温度传感器模块可以形状配合地安装在安装槽中。这是最常见且简单可靠的安装方式。
根据本发明的另一优选实施例，温度传感器模块背向安装槽的轴向端面可以为平坦表面，并且温度传感器模块的轴向长度小于安装槽的轴向深度。这种设计的优点在于，当将温度传感器模块安装到安装槽中之后，温度传感器模块完全位于安装槽之内而不会突出到轴承的轴向端面以外，因此不会改变轴承的整体外部轮廓，避免与其他部件发生干涉。
根据本发明的另一优选实施例，安装槽的底部可以在径向截面中具有 直线轮廓而在切向截面中具有弧线轮廓。这种构造与通常的轴承润滑油槽相适应，并且能够有效防止在轴承结构中引发应力集中现象。
根据本发明的另一优选实施例，可以通过多种方式确保温度传感器模块在安装槽中的稳固安装。例如，安装槽在切向上的两个端部处可以具有固定槽口，温度传感器模块在切向上的两个端部处可以具有固定凸起，当温度传感器模块安装在安装槽中时，固定凸起插入固定槽口中，从而可以将温度传感器模块稳固地安装在安装槽中。此外，温度传感器模块还可以通过高强度、抗老化且耐高温的粘合剂固定在安装槽中。
根据本发明的另一优选实施例，为了便于信号传输，当内转动件和外转动件二者上都安装有温度传感器模块时，这两个温度传感器模块可以位于内转动件和外转动件的同一侧的轴向端面上。
根据本发明的另一优选实施例，温度传感器模块可以是基于声表面波(Surface Acoustic Wave，SAW)传感器或射频识别(Radio Frequency Identification，RFID)传感器的无线无源传感器模块。优选地，这种温度传感器模块可以包括抗金属印刷电路板(Printed Circuit Board，PCB)天线或具有塑料涂层的陶瓷天线。陶瓷天线表面的塑料涂层可以防止陶瓷天线在破碎时分离。
根据本发明的另一优选实施例，温度传感器模块的天线可以具有沿着径向的极化方向，以便放大信号的传输距离。
根据本发明的另一优选实施例，温度传感器轴承组件还可以包括远离内转动件、外转动件和温度传感器模块设置的读取天线和读取器模块，读取天线能够与温度传感器模块的天线无线地通信，从而接收温度传感器模块的温度测量信号，并在读取器模块中进行处理以便读取测量数值。
附图说明
以下结合附图进一步描述本发明。图中以相同的附图标记来代表功能相同的元件。其中：
图1是根据本发明的实施例的温度传感器轴承组件的示意图；
图2是图1中的温度传感器轴承组件的细节示意图；和
图3是根据本发明的另一实施例的温度传感器轴承组件的示意图。
具体实施方式
以下将结合附图描述根据本发明的温度传感器轴承组件的具体实施方式。下面的详细描述和附图用于示例性地说明本发明的原理，本发明不限于所描述的优选实施例，本发明的保护范围由权利要求书限定。
根据本发明的实施例，提供了一种温度传感器轴承组件。图1示出了根据本发明的实施例的温度传感器轴承组件的示意图。如图1所示，该温度传感器轴承组件包括常规的轴承部件：内转动件1、外转动件4、多个滚子3以及保持架2。在本实施例中，内转动件1为轴承内圈，外转动件4为齿圈形式，内转动件1同旋转轴线地安装在外转动件4的径向内侧。多个滚子3安装在内转动件1与外转动件4的径向之间，并且通过保持架2保持沿周向均匀地间隔分布。
此外，该温度传感器轴承组件还包括用于测量轴承温度的部件：安装在内转动件1上的一个或多个温度传感器模块5、安装在外转动件4上的一个或多个温度传感器模块6以及远离轴承的转动件设置的读取天线7和读取器模块8。这里的温度传感器模块5和6都是无线无源传感器模块，即，温度传感器模块5和6不需要外部电源进行供电，并且可以通过无线信号与读取天线7进行通信，从而将自身的温度测量信号发送到读取天线7，继而在读取器模块8中进行处理和读取。这种无线无源传感器模块例如可以是基于SAW传感器或RFID传感器的无线无源传感器模块。温度传感器模块5和6包括用于发射无线信号的天线。天线的类型可以是抗金属PCB天线或陶瓷天线。当温度传感器模块5和6采用陶瓷天线时，可以在陶瓷天线的表面涂覆塑料涂层，这样即使陶瓷天线碎裂也不会发生分离。
图2示出了温度传感器模块5的细节。如图2所示，温度传感器模块5形状配合地安装在内转动件1的轴向端面上的安装槽中。优选地，该安装槽可以是现有轴承结构中原有的结构槽，例如润滑油槽，这样可以在不改变现有轴承结构的前提下安装温度传感器模块。如图2中的放大图所示，与安装槽的轮廓相适应，温度传感器模块5的底部(即与安装槽接触的面) 在切向截面中具有弧线形的轮廓，而在径向截面中具有直线轮廓，这使得温度传感器5沿着径向方向固定，避免了在硬化工艺过程中在内转动件1上产生应力集中现象，并且弧形的接触面保证了温度传感器模块5在安装槽中的良好接触和稳定安装。安装槽的弧形面在切向上的两个端部处可以形成有固定槽口，相应地，温度传感器模块5的弧形面在切向上的两个端部处也可以形成有固定凸起，当温度传感器模块5安装在安装槽中时，温度传感器模块5上的固定凸起可以分别插入相应的固定槽口中，从而将温度传感器模块5相对于安装槽稳定定位。温度传感器模块5的背向安装槽的轴向端面为平行于内转动件1的轴向端面延伸的平坦表面，并且温度传感器模块5的轴向长度小于安装槽的轴向深度，因此当温度传感器模块5安装在安装槽中时，温度传感器模块5完全容纳在安装槽中而不会突出到内转动件1的轴向端面之外，从而避免了对其他部件的干扰。温度传感器模块5中的天线具有沿径向的极化方向，从而可以放大信号的传输距离。此外，在温度传感器模块5与安装槽之间还可以施加高强度、抗老化且耐高温的粘合剂，从而将温度传感器模块5牢固地粘结在安装槽中。
外传动件4上的温度传感器模块6及安装槽与内传动件1上的温度传感器模块5及安装槽的构造基本相同，并且也可以使用相同的方式进行安装。仅有的差别在于，对于外转动件4上的温度传感器模块6，还可以利用外转动件4上原有的吊装螺纹孔来加装螺钉9，从而将温度传感器模块6固定在安装槽中。这种安装方式在图3的替代实施例中示出。
为了便于信号的传输，如图1至图3所示，内转动件1上的温度传感器模块5与外转动件4上的温度传感器模块6优选位于同一侧的轴向端面上。但是根据具体的安装环境，内转动件1上的温度传感器模块5与外转动件4上的温度传感器模块6也可以位于不同侧的轴向端面上。
根据本发明的温度传感器轴承组件可以适用于各种类型的现有轴承，除了上述实施例中示出的具体轴承类型以及标准设计的轴承之外，也可以应用于锥形滚子轴承、圆柱滚子轴承、滚珠轴承或滑动轴承等。
虽然在上述说明中示例性地描述了可能的实施例，但是应当理解到，仍然通过所有已知的和此外技术人员容易想到的技术特征和实施方式的组 合存在大量实施例的变化。此外还应该理解到，示例性的实施方式仅仅作为一个例子，这种实施例绝不以任何形式限制本发明的保护范围、应用和构造。通过前述说明更多地是向技术人员提供一种用于转化至少一个示例性实施方式的技术指导，其中，只要不脱离权利要求书的保护范围，便可以进行各种改变，尤其是关于所述部件的功能和结构方面的改变。
