Description

一种轴承径向间隙检测机构 技术领域
本发明涉及轴承检测技术领域，特别涉及一种轴承径向间隙检测机构。
背景技术
轴承是生产实践中应用非常广泛的标准件，滚动轴承在出厂时，滚动体和滚道之间存在间隙，轴承经过使用、磨损之后，这个间隙将逐渐增大，当间隙超过一定数值以后，轴承将不能继续正常使用，径向间隙为轴承的直径方向的活动间隙数值，径向间隙数值可以体现此轴承使用磨损的程度，现有的对轴承的径向间隙的检测中，通过测量设备测量轴承外圈与内圈之间的可活动间隙，常使用的方法为通过百分表接触轴承外圈表面，将轴承内圈固定，而后沿测量方向往复活动轴承外圈，通过百分表记录两次数值，数值之差即为轴承的径向间隙。
然而，就目前传统的测量方式而言，直接将轴承内圈套接在定位轴上，测量过程中手动扶持轴承外圈，将轴承外圈沿轴承的径向方向往复拨动，通过百分表测量拨动的最大间隙，而此种测量方式和轴承定位方式，不能对不同内径的轴承进行固定，且不能保证百分表的测量顶针与轴承轴线垂直，不能保证百分表的测量顶针与轴承外圈的推进方向保持一致，导致测量容易出现误差，测量精度偏低。

此外，根据本发明的实施例，如图9所示，外圈夹架5的前方和后方固定连接有夹架滑块501，夹架滑块501滑动连接侧导轨1011，外圈夹架5的下表面固定连接有两处夹架下推板502，夹架下推板502上开设有螺旋孔，螺旋孔螺旋连接双向丝杠7，外圈夹架5的上端固定连接有外圈夹头503，外圈夹头503内表面开设有弧形槽，外圈夹头503上横向贯穿开设有圆孔结构的检测孔5031，检测孔5031的内表面弧形槽上滚动连接有两处定位夹轮5032，双向丝杠7的中间固定连接有从动齿筒701，从动齿筒701通过齿轮传动连接固定主动齿轮10，双向丝杠7上通过轴承转动连接有两处滑动轴承座702，两处滑动轴承座702位于检测推块603的两侧，且滑动轴承座702的内表面固定连接调节顶簧6031外端；通过夹紧驱动件9、固定主动齿轮10和双向丝杠7的配合，固定主动齿轮10与从动齿筒701啮合传动，驱动双向丝杠7转动，双向丝杠7两侧的螺旋方向相反，分别与两侧外圈夹架5的夹架下推板502螺孔形成螺旋传动，通过双向丝杠7的单向旋转，可以驱动两侧的外圈夹架5同步向里移动和向外移动，对轴承的外圈实现夹紧的效果，通过定位夹轮5032的作用，对不同外径的轴承外圈均设有四处接触点，稳定外圈的固定效果和适用范围。
此外，根据本发明的实施例，如图8所示，横向测量推架6的下表面固定连接有两处测量滑块601，测量滑块601滑动连接在下导杆1031上，横向测量推架6的前表面固定连接有测量推板602，横向测量推架6的上表面中间固定连接有检测推块603，检测推块603中间设有滑孔，滑孔滑动连接内滑动导杆1021，检测推块603的左侧和右侧分别固定连接有一处调节顶簧6031，检测推块603滑动连接在内滑动导杆1021上，并且与两侧的滑动轴承座702通过两调节顶簧6031连接，使得双向丝杠7与横向测量推架6之间的连接关系为弹性连接，当伸缩驱动件8伸缩时，即可驱动横向测量推架6进行左右往复移动，通过双向丝杠7推动外圈夹架5，外圈夹架5对轴承外圈夹持并施加横向推动的力，在内圈固定不动的基础上，两侧偏移的间隙即为径向间隙，通过横向设置的百分表4测量并记录，即可计算轴承的横向间隙数值，保证了推进方向与百分表4的检测针方向一致。
本实施例的具体使用方式与作用：本发明中，首先，将轴承的轴线方向朝向前后方向，而后将轴承从后向前移动，使轴承内圈套接在四处扩张撑杆303上，而后手动旋转双向调节丝杠201，通过双向调节丝杠201与扩张推孔302的螺旋传动，推动两处内圈扩张顶架3同时向中间或者两侧移动，通过增加两组扩张撑杆303之间的横向间距对轴承内圈进行固定，而后通过夹紧驱动件9驱动固定主动齿轮10旋转，固定主动齿轮10与从动齿筒701啮合传动，驱动双向丝杠7转动，双向丝杠7两侧的螺旋方向相反，分别与两侧外圈夹架5的夹架下推板502螺孔形成螺旋传动，通过双向丝杠7的单向旋转，可以驱动两侧的外圈夹架5同步向里移动和向外移动，对轴承的外圈实现夹紧的效果，通过定位夹轮5032的作用，对不同外径的轴承外圈均设有四处接触点，稳定外圈的固定效果和适用范围；使百分表4的测量端接触轴承外圈表面，并对百分表4的底座进行辅助固定，而后控制伸缩驱动件8伸缩运动，驱动横向测量推架6进行左右往复移动，通过双向丝杠7推动外圈夹架5，外圈夹架5对轴承外圈夹持并施加横向推动的力，在内圈固定不动的基础上，两侧偏移的间隙即为径向间隙，通过横向设置的百分表4测量并记录，记录双向丝杠7收缩时百分表4的测量数值和记录双向丝杠7展开时百分表4的测量数值，再取两数值的差，即可计算轴承的横向间隙数值。
最后，需要说明的是，本发明在描述各个构件的位置及其之间的配合关系等时，通常会以一个/一对构件举例而言，然而本领域技术人员应该理解的是，这样的位置、配合关系等，同样适用于其他构件/其他成对的构件。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
