所述安装通道22包括有径向延伸段221和轴向延伸段222，所述径向和轴向均是以轴承中心为基准，所述径向延伸段221的一端连通至套接孔21的内圆周面，所述轴向延伸段222于压板2的一侧的轴向端面上设置有安装口23，所述限位构件4穿设固定在轴向延伸段222中，所述径向延伸段221中活动设置有球体支撑座5，所述球体支撑座5的一端包括有与钢珠3配合滚动接触的球窝51，所述的凹槽20由球窝51提供，所述球体支撑座5的另一端与限位构件4配合抵接限位。在安装钢珠3时，可将球体支撑座5适当的推动至与轴向延伸端222相靠近的位置，使径向延伸端221的一端形成有一个可供钢珠3完全置入的槽，钢珠3可沿套接孔21的内侧安装到所述槽中，使钢珠3不容易掉落。
所述限位构件4为螺接固定在轴向延伸段222中的螺钉，轴向延伸段222的内侧设置有与螺钉配合的螺纹。
为了提高球体支撑座5和螺钉的抵接配合效果，所述球体支撑座5的另一端设置有与螺钉的杆部相吻合的凹部52，凹部52内侧和轴向延伸段222的内圆周壁设置有相吻合的螺纹，使球体支撑座5不容易产生径向的晃动，也能够减少接触部位的磨损。
所述安装口23处设置有导向部，导向部的设置能够与螺钉的头部配合进行限位，方便螺钉的安装，当然也能够起到对螺钉的导向插入的作用，方便安装。
本发明的快速连接的压板轴承装置的实施例2如图3-4所示，实施例2与实施例1结构基本相同，仅有的区别在于：所述轴向延伸段222于压板2的两侧的轴向端面均设置有安装口23，采用两个分别设置在压板2轴向的两侧端面的安装口23一方面方便安装通道22的生产加工成型，另一方面能够方便限位构件4的安装以及推动球体支撑座5朝钢珠3方向运动。所述安装口23处设置有导向部，导向部的设置能够与螺钉的头部配合进行限位，防止螺钉过度深入到轴向延伸段222中。
本发明的快速连接的压板轴承装置的实施例3如图5-6所示：包括轴承1、压板2，所述压板2包括有能够套设在轴承1外圈外侧的套接孔21，所述套接孔21和轴承1外圈的套接配合处设置有限位槽，所述限位槽中设置有钢珠3，基于钢珠3和套接孔21、轴承1外圈之间的限位配合构成轴承、压板之间的轴向限位，所述轴承1外圈或压板2设置有与所述限位槽相连通的安装通道22，所述安装通道22中设置有能够将钢珠3限位保持在所述限位槽中的限位构件4。
所述安装通道22设置在压板2上，所述限位槽包括有环绕设置在轴承1外圈的外圆周面上的第一环形滚槽11、环绕设置在压板套接孔21的内圆周面处的第二环形滚槽24，通过第一环形滚槽11和第二环形滚槽24的配合形成环形的滚道，滚道中配置有多个钢珠3，为了使压板2和轴承1之间的受力更加均匀，这些钢珠3几近装满整个滚道。
所述安装通道22至少为一个，钢珠3通过安装通道22装入到所述限位槽中，所述安装通道22的一端连通至第二环形滚槽24中，所述安装通道22 的另一端连通至压板2一侧的轴向端面上并于该轴向端面上设置有安装口23，所述限位构件4设置在所述安装口23处，限位构件4采用螺钉或其他类型的紧固件，限位构件4安装在安装口23中时能够防止钢珠3脱出，提高了使用时的可靠性。
当然，所述安装口23处也设置有导向部，在本实施例中所述导向部还能够起到对钢珠3进行导向置入的作用。
本发明的快速连接的压板轴承装置的实施例4如图7所示，实施例4与实施例3结构基本相同，仅有的区别在于：所述安装通道22呈倾斜设置，倾斜设置的安装通道22使得在对钢珠3进行安装时，钢珠3在重力作用下能够自动滚入到限位槽中，从而更方便安装。
本发明的快速连接的压板轴承装置的实施例5如图8所示：包括轴承1、压板2，所述压板2包括有能够套设在轴承1外圈外侧的套接孔21，所述套接孔21和轴承1外圈的套接配合处设置有限位槽，所述限位槽中设置有钢珠3，所述轴承1外圈或压板2设置有与所述限位槽相连通的安装通道22，所述安装通道22中设置有能够将钢珠3限位保持在所述限位槽中的限位构件4。
在本实施例中，所述限位槽为多个并沿轴承1中心周向均布，所述限位槽包括有设置在轴承1外圈外圆周面上的第一槽12和设置在压板套接孔21内圆周面上的第二槽25，压板2上设置有多个与第二槽25对应连接配合的安装通道22，基于钢珠3和套接孔21、轴承1外圈之间的限位配合构成轴承1、压板2之间的轴向以及周向的限位配合。
所述安装通道22包括有径向延伸段221和轴向延伸段222，所述径向延伸段221的一端连通至套接孔21的内圆周面，所述轴向延伸段222于压板2的一侧的轴向端面上设置有安装口23，所述限位构件4穿设固定在轴向延伸段222中并与所述钢珠3配合抵触限位，所述第一槽12由径向延伸段221的一端构成。
所述安装口23处设置有导向部，所述导向部能够起到对钢珠3进行导向置入的作用。
以上实施例，只是本发明优选地具体实施例的一种，本领域技术人员在 本发明技术方案范围内进行的通常变化和替换都包含在本发明的保护范围内。
