Description

一种轴承座组件、使用了轴承座组件的精轧机鼓形齿接轴和用于鼓形齿接轴的平衡装置 技术领域
本发明涉及机械传动结构领域，尤其涉及精轧机鼓形齿接轴的结构。
背景技术
薄板坯连铸连轧等现代冶金生产的先进技术，需要大型、高效、高精的轧制设备，因此给相关备件产业提出了新的挑战。对于薄板带钢热轧连轧精轧机组和连铸连轧机组而言，由于主传动轴是整套连轧设备的关键传动部件，其性能、质量与板带产品的产量和质量有着直接的关系，其技术要求越来越高。

申请号为201420455123.X的中国实用新型专利公开了一种内循环稀油润滑鼓形齿接轴，包括轧辊连接端、传动连接端、密封装置、中间轴、弹簧装置、供油环；所述轧辊连接端具有第一油腔以及第三油腔；所述传动连接端具有第二油腔以及第四油腔；所述第一油腔与第三油腔连通；所述第二油腔与第四油腔连通；所述传动连接端设置有连通第四油腔的出油孔；所述中间轴具有中心通孔；所述供油环安装在中间轴的外圆周面上；所述中间轴上设置有供油孔；所述中心通孔通过供油孔与供油环连通，还包括第一堵头、第二堵头；所述第一堵头位于第一油腔内，所述第一堵头密封中心通孔在中间轴轧辊端的开口；所述第一堵头上设置有第一喷头以及与中心通孔连通的斜孔；所述第一喷头连通斜孔与第一油腔；所述弹簧装置设置在中心通孔内；所述弹簧装置上设置有第二堵头；所述第二堵头与中心通孔滑动配合；所述第二堵头与传动连接端连接；所述第二堵头上设置有第二喷头；所述第二喷头连通中心通孔与第二油腔；所述中间轴内设置偏离中间轴中轴线的回油 通道；所述回油通道连通第三油腔与第二油腔。该方案在中间轴上设置油环，在中间轴内设置中心通孔和回油通道，通过回油通道进油后，进一步的进入中心通孔，然后对齿部进行供油。这种方式下，回油通道在中间轴转动过程中，润滑油会产生一个离心力，从而给对供油压力提出一定要求，并且这种方式通过在中间轴上安装进油环，进油环在压力下密封效果差，也无法通过进油环承受一定的作用力。
上述两种接轴均通过进油环或供油环来添加润滑油，共同存在如下问题：1、进油环由于加工精度不够且其本身耐磨性差，使用过程中发生磨损变形，而导致进油环抱死；2、因进油环与中间轴相对运动，进油环悬浮在轴体上，其端面存在0.3-0.5mm间隙，加油时润滑油脂容易从端面泄露导致辊端齿部润滑不充分。

具体实施方式
下面结合附图和实施例来详细说明本发明的具体内容。
如附图1所示，本发明的精轧机鼓形齿接轴，该鼓形齿接轴使用了轴承座组件和平衡装置，包括依次连接的辊端组件1、中间轴3和齿端组件，还包括平衡装置和固定在平衡装置上的轴承座组件，所述轴承座组件与中间轴3通过滚动轴承12连接，所述轴承座组件上设置第一进油孔，所述滚动轴承12上设置径向的第二进油孔42，所述中间轴3上设有轴向的轴体深孔，所述第一进油孔、第二进油孔42和轴体深孔连通。
从上述结构可知，本发明鼓形齿接轴的润滑方式是通过第一进油孔与第二进油孔42安装时保持一致，润滑油从第一进油孔进油，在油压的作用下流向滚动轴承12，然后进入轴体深孔，进而达到润滑的目的。与现有技术相比，本发明不再通过进油环进油，用滚动轴承12代替进油环滑动摩擦，克服了原先进油环加工精度不够，易变形导致抱死的问题。
本发明的平衡装置上设置轴承座组件；通过轴承座组件中的滚动轴承12支撑中间轴3，在获得良好的润滑进油效果的同时，利用平衡装置在中心轴3上的位置，来实现润滑和平衡两重作用。由于滚动轴承12支撑中间轴3，因此平衡装置本身对中心轴3的支撑也得到了改善，因为滚动轴承12位置可以受较大的力的作用；本发明的将润滑进油的功能集合到平衡装置内，解决了进油环变形问题的同时还带来了平衡功能改善的技术效果。
如图3、4、5所示，所述轴承座组件包括轴承座本体8、第一隔套4、第二隔套10、第一轴承压盖6、第二轴承压盖9和压板5，轴承座本体8用于安装所述滚动轴承12，第一隔套4和第二隔套10分别位于所述滚动轴承12两端且与中间轴3固定连接；第一轴承压盖6与第二轴承压盖9分别位于所述滚动轴承12外圈两端部，且第一轴承压盖6和第二轴承压盖9与第一隔套4和第二隔套10之间存在间隙(参见图4、图5)，该间隙使得轴承压盖(包括第一轴承6压盖和第二轴承压盖9)和隔套(包括第一轴套4和第二轴套10)之间可以自由的发生相对运动；所述第一进油孔设置于所述轴承座本体8上。压板5位于所述滚动轴承12两端且与所述轴承座本体8可拆卸连接，所述第一轴承压盖6或第二轴承压盖9上设置有第三进油孔43；所述轴承座组件内设置有密封组件。
如图4所示，所述密封组件包括分别设置于所述第一轴承压盖6、第二轴承压盖9与所述轴承座本体8的配合止口的两道密封圈7，还包括与第一轴承压盖6和第二轴承压盖9配合安装的骨架密封组。
所述骨架密封组包括第一骨架密封11和第二骨架密封13，所述第一骨架密封11和第二骨架密封13均由凹字形的柔性密封装置和角钢截面形状的支撑件组成；其中第一骨架密封11和第二骨架密封13的凹口相向设置；第一骨架密封11和第二骨架密封13的外侧与轴承压盖(包括第一轴承6压盖和第二轴承压盖9)和隔套(包括第一轴套4和第二轴套10)接触；支撑件的外侧边部与第一骨架密封11和第二骨架密封13的与轴承压盖(包括第一轴承6压盖和第二轴承压盖9)接触的外侧相对应的内侧接触。此外，第一骨架密封11和第二骨架密封13也可以是包括了支撑件和包裹在支撑件外的柔性密封装置组成。
柔性密封装置和支撑件组成的骨架密封(包括第一骨架密封11和第二骨架密封13)，在使用过程中，骨架密封整体不会发生变形，柔性密封装置可以始终有效的与隔套接触，从而在发生旋转时不会由于骨架密封的柔性密封装置变形而导致漏油；此外，支撑件使得骨架密封具备了一定的承压能力，当外部给入的润滑油需要一定压力时，齿接轴内的骨架密封也不会因为润滑油压力而变形。通过这样的骨架密封、轴承压盖、隔套的配合使用，使本发明在保证润滑有效性的同时，同时能给承受更高的润滑油给油的压力。
现有技术中使用进油环由于转动需要端面存在0.3-0.5mm间隙，容易造成漏油、灰尘进入，通过取消进油环及设计密封组件，从而可以避免漏油以及灰尘的进入，有效解决了润滑不充分及油品失效的问题。现有鼓形齿接轴研发方向更多聚焦在如何实现稀油内循环或者如何提高承载能力上，对于0.3-0.5mm间隙而产生的润滑故障是极难关注到的，因而也没有相关现有结构是用于解决这一问题的；同时现有技术也没有关注将平衡装置与中心轴3接触的位置利用作为进油装置从而取消进油环；本发明的方案既解决了进油环变形、间隙导致的润滑故障，又更好的为平衡装置提供了中心轴3的支撑位置。
所述第一隔套4或第二隔套10一端连接用于调节所述滚动轴承12的安装间隙的调节组件，所述调节组件包括依次通过螺栓固定连接的连接环14、调整垫片15、第一连接盘16以及第二连接盘17，所述连接环14用于连接所述第一隔套4或第二隔套10。调整垫片15采用弹性材料支撑，例如橡胶或者其他人工合成的柔性材料。通过设置调节组件，能进一步的缩小滚动轴承12的安装间隙，避免漏油以及灰尘进入。
参见图1，中间轴3上还包括设置在阶梯凸台直径细段部分的凹槽，其中中间轴3的阶梯凸台可以用来在轴向方向上固定轴承座组件，凹槽可以用来容纳第一连接盘16，从而将轴承座组件固定在中间轴3上。这样的固定方式在是沿着中间轴3的周向方向的，因此，强度较大，能够承受轴向方向的较大的作用力。
如图2所示，所述辊端组件1与所述中间轴3之间通过过渡齿轮2连接。
如图3所示，所述齿端组件包括齿端内齿圈19和齿端轴套20。所述齿端内齿圈19和齿端轴套20之间通过牙嵌、端面齿或端面键固定连接。通过上述连接方式，让出原先花键连接所需空间，加大鼓形齿齿部啮合分度圆，提高齿端内齿圈19整体强度，延长齿端内齿圈19在线使用寿命。同时，通过螺栓联接形式代替原先花键结构，便于现场直接更换齿端内齿圈19，提高现场维护效率。
本发明在轴承座组件上设有第一进油孔，通过第一进油孔可以与润滑油管道连接，向轴承座本体8和中间轴3内部供给润滑油。
如图6所示，所述齿端内齿圈19外圆设置迷宫凸台。此种设计可防止润滑油沿着齿端内齿圈19外圆流向齿轮机座，造成油品泄露。随着进油环漏油问题的解决，油箱安装位置缩短至齿端端盖18处。
所述齿端组件内设置温度传感器和振动传感器。具体的，温度传感器及振动传感器置于标牌内部，并通过铆钉安装在内齿套齿轮副外圆部位。通过设置温度传感器，能够在线监测接轴齿部工作温度，消除了现有鼓形齿式联轴器工作过程中齿部啮合异常发热，加速齿轮磨损的缺陷，通过设置振动传感器，可以有效在线检测接轴工作时振动幅度，消除了现有鼓形齿式联轴器工作过程中因异常使用，抖动大而无法监测的缺陷。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
