Description

连铸机用轴承座和轴承组件 技术领域
本申请属于钢铁生产领域，特别涉及一种连铸机用轴承座和轴承组件。
背景技术
连铸机是钢铁生产中的常用机械，特别在连铸机的弯曲段和扇形段，连铸机的负载是一个非常重要的工艺参数。用于希望监控辊子的载荷，以优化生产过程和监控轴承的工作状态。
连铸机的辊子和轴承在高温(大约300摄氏度)的环境下工作。高温不仅使大多数的传感器难以正常工作，而且还可能导致轴承座的永久变形。
可能的现有技术中可以使用以下方法测量辊子的载荷：
(1)使用应变片，包括在轴承或轴承座上粘贴或焊接应变片。但是粘贴的应变片可以因温度和冲击的影响而失效，焊接的应变片受温度的影响也很大。
(2)施加载荷可以引起轴承内圈和轴承外圈之间的径向或轴向位移，通过测量位移量来检测载荷。但是由于高温可能造成轴承永久性变形，变形量大至100微米，因此测量位移量的方案不适用于连铸机。

具体实施方式
为了更加清楚地阐述本申请的上述目的、特征和优点，在该部分结合附图详细说明本申请的具体实施方式。除了在本部分描述的各个实施方式以外，本申请还能够通过其他不同的方式来实施，在不违背本申请精神的情况下，本领域技术人员可以做相应的改进、变形和替换，因此本申请不受该部分公开的具体实施例的限制。本申请的保护范围应以权利要求为准。
在下面的描述中，如果没有单独说明，长度方向X表示轴承座1的长度方向，宽度方向Y表示轴承座1的宽度方向，轴承座1的宽度方向与安装于轴承座1的轴承的轴向一致。长度方向X和宽度方向Y相互垂直。
如图1至图4所示，本申请提出一种连铸机，连铸机包括轴承座1、轴承和辊子3。轴承安装于轴承座1，辊子3通过轴承能够转动地连接于轴承座1。
轴承座1可以包括轴承座本体11、轴承座底座12、端盖13和传感器2。轴承座底座12可以连接于轴承座本体11的底部，例如轴承座底座12和轴承座本 体11可以通过螺钉连接。端盖13连接于轴承座本体11，例如端盖13和轴承座本体11可以通过螺钉连接。端盖13位于轴承的轴向的一端，通过端盖13可以将轴承限位于轴承座本体11的轴承安装孔111。
如图2至图4所示，轴承座本体11设置有轴承安装孔111，轴承安装孔111沿轴承座的宽度方向Y延伸，轴承安装孔111内可以安装轴承，例如轴承安装孔111内可以安装调心滚子轴承(SRB)。
轴承座本体11的底面设置有传感器安装孔112，传感器安装孔112的开口朝向轴承座底座12。传感器安装孔112为盲孔，传感器安装孔112用于容纳传感器2，盲孔可以使传感器2受到的载荷较小，承受载荷较小的传感器2体积较小，成本较低。传感器安装孔112的底面为平面，平面的底面使安装于传感器安装孔112内的传感器2能够和传感器安装孔112的底面接触贴合得比较稳定。
轴承座底座12可以接触并挤压传感器2，使传感器2被预加载。也就是说，在轴承没有受到载荷时，传感器2已经受到挤压了，这样可以避免轴承承受载荷而传感器2还未加载的情况，使传感器2的测量数值准确。例如，可以通过传感器2的高度稍大于传感器安装孔112的深度实现传感器2被预加载。
如图3和图4所示，传感器安装孔112设置有多个，例如两个。传感器安装孔112包括第一传感器安装孔112A和第二传感器安装孔112B，两个传感器安装孔112各安装一个传感器2。
第一传感器安装孔112A和第二传感器安装孔112B在轴承座1的宽度方向Y上(轴承的轴向)间隔开，第一传感器安装孔112A和第二传感器安装孔112B的位置可以对应于调心滚子轴承的两排滚动体。安装于第一传感器安装孔112A和第二传感器安装孔112B的两个传感器可以检测到两排滚动体的偏载，即两排滚动体的受力不均。
可以理解，轴承安装孔111内也可以安装两个轴承，第一传感器安装孔112A和第二传感器安装孔112B的位置可以分别对应于这两个轴承，使两个传感器可以检测到两个轴承的偏载，即两个轴承的受力不均。
第一传感器安装孔112A和第二传感器安装孔112B在轴承座1的长度方向X上间隔开。进一步的，第一传感器安装孔112A和第二传感器安装孔112B位于经过轴承安装孔111的轴线的竖直面的两侧，即，第一传感器安装孔112A和第二传感器安装孔112B在轴承的周向上错开。通过间隔开的两个传感器2可以校准轴承座1永久形变的影响并检测负载错位角。例如负载错位导致对轴承座1的负载不是竖直向下时，两个传感器的数据会产生明显差异。
轴承座本体11的底面设置有凹槽113，凹槽113的一端与传感器安装孔122连通，凹槽113的另一端延伸至轴承座1的边缘，凹槽113可以沿宽度方向Y延伸。凹槽113可以容纳传感器2的线缆，传感器2的线缆沿凹槽113延伸至轴承座1的外部。传感器2的线缆可以为耐高温电缆，传感器2和处理器可以通过耐高温电缆连接。
可以理解，凹槽也可以设置于轴承座底座12，通过凹槽在轴承座本体11和轴承座底座12之间形成容纳传感器2的线缆的通道即可。
传感器2为载荷传感器，传感器2可以包括压电石英材料，压电石英材料的居里温度较高并且温度可以保持稳定，居里温度可以达到573摄氏度，因此传感器2能够在高温环境下工作。这种负载传感器2适合于检测动态负载，不适检测静态负载。通过检测动态负载，可以校准因高温和载荷引起的轴承和/或轴承座永久形变引起的测量误差。永久形变引起的测量误差使传感器输出的是直流信号，而轴承的实际载荷是动态变化的，使传感器输出的是交流信号，通过对传感器输出的信号进行处理，可以对轴承和/或轴承座永久形变引起的测量误差进行校准。
传感器2可以基于压电效应原理工作的，当压电材料承受负载时，压电材料的表面就会产生电荷，电荷量的负载的大小成正比。处理器可以处理这些电荷和相应的输出电压，处理器可以连接例如可编程逻辑控制器(PLC)的数据采集设备，从而获取负载数据。
传感器2不直接接触轴承，传感器2测得的载荷实际上并不是轴承或轴承座受到的实际载荷，然而传感器2测得的载荷与实际载荷成正比。为了验证 这一点，进行了有限元分析来分析实际载荷与传感器2的输出数值之间的关系。
在有限元分析中，连铸机的辊子由多个轴承座支撑，例如通过4个轴承座支撑，每个轴承座1安装两个传感器，例如传感器1和传感器2安装于同一个轴承座，传感器3和传感器4安装于同一个轴承座，以此类推。

在表1中，实际载荷的单位为千牛顿(KN)，传感器的输出数值单位为牛顿(N)。在图5中横坐标表示实际载荷，单位为千牛顿(KN)，纵坐标表示传感器的输出数值，单位为牛顿(N)。从表1和图5中可以看出，传感器的输出数值远小于实际载荷，传感器的输出数值和辊子的实际载荷成正比。通过有限元分析和/或实验掌握上述正比例关系，就可以通过传感器2的输出数值计算得到辊子的实际载荷。
除了有限元分析之外，也可以在实验室中测试连铸机，用实验结果验证有限元分析结果，进一步保证结果的准确性。经过有限元分析和/或实验的过程，将传感器2输出的数值和实际载荷进行关联校准之后，获得传感器2的输出数值与辊子的实际载荷之间的关系，就可以通过传感器输出的数值计算得出辊子的实际载荷。
本申请的连铸机结构紧凑，易于制造而用于实际生产。通过使用压电石英材料的传感器，使传感器2可以在高温环境中使用，测量动态负载。通过传感器2检测动态负载，可以校准因高温和载荷引起的轴承和/或轴承座的形状永久形变引起的测量误差，通过传感器输出的数值计算得出辊子的实际载荷。
虽使用上述实施方式对本申请进行了详细说明，但对于本领域技术人员来说，本申请显然并不限于在本说明书中说明的实施方式。本申请能够在不脱离由权利要求书所确定的本申请的主旨以及范围的前提下加以修改并作为变更实施方式加以实施。因此，本说明书中的记载以示例说明为目的，对于本申请并不具有任何限制性的含义。
