Description

轴承限位系统及限位方法 技术领域
本申请涉及一种轴承限位系统及限位方法。
背景技术
轴承是在机械传动过程中起固定和减小载荷摩擦系数的部件，它的主要功能是支撑机械旋转体，用以降低设备在传动过程中的机械载荷摩擦系数。按运动元件摩擦性质的不同，轴承可分为滚动轴承和滑动轴承两类。
轴承是各类机械装备的重要基础零部件，它的精度、性能、寿命和可靠性对主机的精度、性能、寿命和可靠性起着决定性的作用。因此，在轴承安装到位后，还需要采取措施对轴承进行限位，以防止轴承发生位移而导致设备运转性能降低，甚至导致机械装备的损害。
现有技术中，对轴承内圈一侧限位一般是通过在轴上设置轴肩的方式实现，在另一侧对轴承内圈进行限位的技术主要有以下几种：一种是通过在轴上设槽或螺纹，通过这个槽或者螺纹固定一个限位部件，进而利用该限位部件对轴承进行限位；另一种是以过盈配合的方式进行限位；第三种是利用粘接的方式进行限位；第四种是在轴端安装轴盖。
过盈配合和粘接的方式，可靠性差。通过在轴上设槽或者螺纹的方式，对轴承内圈进行限位，会对轴的强度造成损害，从而影响整个机械装备的性能和运行安全。在轴端安装轴盖的方法，无法适用于长轴轴承。长轴轴承而言，长轴结构通常设计为锥形，距离载荷端较远的一段通常轴径较小。
发明内容

作为实施方式之一，该第二钢性部件5设有与该限位凸起1相配合的卡接部7。
作为实施方式之一，该钢性作用力传导部3为至少一个一体成型圆环和/或至少一个多瓣扣合圆环。
根据本发明的另一方面，提供一种轴承限位方法，该方法包括，以在轴上一体成型的限位凸起为着力点，在轴承的装配位置，由远端向近端，对轴承内圈沿轴施加径向作用力。该限位凸起的外径小于该轴承内圈的内径。
作为具体实施方式，该轴承限位方法包括，在该限位凸起与该轴承内圈之间，设置作用力传导部，该轴承内圈的内径小于作用力传导部的最大外径，该轴承内圈的外径大于作用力传导部的最大外径。

具体实施方式
以下，将参照附图来详细说明本发明的具体实施方式。本发明具体实施方式提供的轴承限位系统应用于长轴轴承，其长轴为锥形，距离载荷端较远的一段轴径较小。本发明中，定义距离载荷端较远、轴径较小的一端为远端；距离载荷端较近、轴径较大的一端为近端。本发明实施例正是利用了长轴为锥形的特点，设计出了一套轴承限位系统。
实施例一
如图1所示，其为本发明实施例的轴承限位系统的结构示意图之一，本实施例的轴承限位系统包括限位凸起1、轴承内圈2和作用力传导部3，该作用力传导部3设于该限位凸起1与该轴承内圈2之间，该轴承内圈2的内径大于该限位凸起1的外径。其中，限位突起1优选为与轴一体成型。
其中，限位凸起1设置在距离轴承安装部位一定距离的部位，作用力传导部3与限位凸起1和轴承内圈2相抵接，从而将限位凸起1的限位作用传递到了轴承内圈2上。作用力传导部3优选为环状结构，其靠近限位 凸起1的一侧的内径小于限位凸起1的外径，从而能够抵接在限位凸起1上。限位突起可以采用与轴一体成型的凸起挡环的形态。
此外，为了保证不影响轴承外圈和滚子的安装和拆卸，轴承内圈2的内径可以小于作用力传导部3的最大外径，而该轴承内圈2的外径大于作用力传导部3的最大外径。
作用力传导部3为至少一个一体成型圆环和/或至少一个多瓣扣合圆环。作用力传导部3可以为弹性部件和/或弹性部件部件，如果采用弹性部件，可以借助弹性从长轴的轴径较小的一端套入到限位凸起1与该轴承内圈2之间。如果为钢性部件，作用力传导部3也可以加热后从长轴的轴径较小的一端套入到限位凸起1与该轴承内圈2之间，然后冷却后与限位凸起1和轴承内圈2相抵接。不过在实际应用中，作用力传导部3优选地采用沿着圆周方向拼接而成的结构，即采用多瓣扣合圆环，从而安装时不需要沿着轴向进行套接。例如图1所示，作用力传导部3为两瓣对开的固定环，在轴承内圈安装完成之后，在凸起的挡圈和轴承内圈之间安装两瓣对开的固定环，在固定环的接口处开设螺纹孔，两瓣之间采用内六角螺栓连接。
本实施例的轴承限位系统，在通过在长轴上设计外径不超过轴承内限位凸起，并通过作用力传导部将限位作用传递到了轴承内圈，实现了在不影响轴承内圈装配和长轴的强度的前提下，对轴承内圈进行了有效的机械固定。
实施例二
如图2所示，其为本发明实施例的轴承限位系统的结构示意图之二，与实施例一的不同之处在于，作用力传导部3包括第一钢性部件4和第二钢性部件5，其中，该第一钢性部件4位于轴承内圈2一侧，该第二钢性部件5位于该限位凸起1一侧。优选地，第一钢性部件4为钢性环，过盈配合安装于轴上(即第一钢性部件为过盈环)，并与该轴承内圈相接。第二钢性部件5也可以同实施例一一样，采用两瓣或多瓣对开的固定环的形式。如图4所示，第一钢性部件4和第二钢性部件5可以通过螺栓8连接在一起。具体地，可以在第一钢性部件4的轴向方向上设有螺纹孔，同时第二钢性部件5的轴向方向上也对应设置螺纹孔，通过螺栓将两者连接在 一起形成一个整体，并最终通过第二钢性部件5抵接到限位凸起1上。
过盈环依靠过盈配合防止轴承内圈的轴向移动，但这种方式也存在失效的风险，因此，再配合一个两瓣对开的固定环，能够有效防止过盈环的失效，能够更加有效地防止轴承内圈的轴向移动。
实施例三
如图3所示，其为本发明实施例的轴承限位系统的结构示意图之三，与实施例二的不同之处在于，本实施例中的第一钢性部件(即过盈环)4和第二钢性部件5之间间隔一定距离，并通过连接部件6连接在一起，连接部件6具体可以采用螺栓。在使用过程中，可以在安装完轴承和第一钢性部件4后，再安装第二钢性部件5，并通过螺栓将两者穿接在一起，最后再通过螺母进行紧固。采用这种方式，能够使得第一钢性部件4和第二钢性部件5之间具有一定的间隙，以保证第二钢性部件5能够顺利安装到轴上，同时也节省了轴承限位部件的材料。与上述实施例一样，第二钢性部件5也可以同实施例一一样，采用两瓣或多瓣对开的固定环的形式。作为本实施例的进一步改进，也可以取消第一钢性部件(即过盈环)4，而仅保留第二钢性部件5，第二钢性部件5通过与其连接的螺栓直接抵接到轴承内圈上。
实施例四
在本实施例主要涉及对限位凸起1所进行的进一步改进，如图3所示，限位凸起1还可以采用一个或多个沿着周向设置的凸起挡块的形式，其外径一般小于(至少是不大于)轴承内圈2的内径，以保证不影响轴承内圈2的安装和拆卸。凸起挡块可以为方形(图中所示为方形)或圆弧形。
如果在轴上设计了挡块，则可以将整个作用力传导部3或者上述的第二钢性部件5设计为一种特殊结构的钢性环，该钢性环为锥形的环状结构(如图6所示)，与轴的形态相吻合，钢性环上开有与轴上挡块尺寸和数量相配合的通槽和半通槽(即图3所示的卡接部7)，同时设计有轴向的螺纹孔。钢性环的外径不能大于轴承内圈的外径，以保证钢性环不影响轴承外圈和滚子的安装和拆卸。如图5和图6所示，图5为本发明实施例的钢性环的截面结构示意图之一(沿着圆周所在的平面进行剖面)，图6为本发明实施例的钢性环的截面结构示意图之二(沿着轴线所在的平面进行 剖面)，图中所示的钢性环开有通槽b，半通槽c和螺栓孔a。
以图3所示的结构为例，将第二钢性部件5设计为一种特殊结构的钢性环，同时配合作为第一钢性部件4的过盈环来实现限位。其安装过程如下：在过盈环3完成安装后，安装第二钢性部件5，首先使用通槽b对准轴上的凸起挡块，完全推入到轴上的凸起挡块的右侧后，旋转一定的角度，使第二钢性部件5上的半通槽c对准轴上的凸起挡块，然后向左移动挡环，使凸起挡块顶住半通槽c。此外，作为进一步改进，半通槽c也可以设计成L形，使钢性环不能继续向轴端方向移动。
在安装完第二钢性部件5之后，在螺纹孔a中拧入作为连接部件6的螺栓8，螺栓可以采用内六角平端螺栓，拧入的螺栓数量根据轴的外径选择，拧入后，使螺栓的平端顶住第一钢性部件4，之后继续旋转螺栓，由于第二钢性部件5内也有螺纹，继续旋转螺栓将会推动第二钢性部件5向左侧移动，直至轴上的凸起挡块与第二钢性部件5上的半通槽c相抵接，从而整个系统被顶紧，待螺栓旋转到位后，可以安装垫片和螺母进行最后的紧固。
以上通过四个实施例介绍了本发明的技术方案，各个实施例中所采用的改进点也可以相互组合。因此，在整体上，对上述实施例的各种变形进行如下总结性说明：上述钢性环既可以单独构成作用力传导部3，一端与挡块卡接，另一端与轴承内圈相接。也可以与至少另一钢性部件共同构成作用力传导部3，该钢性环(即钢性部件5)作为作用力传导部的一端，与挡块卡接，另一钢性部件(即钢性部件4)作为该作用力传导部的另一端与轴承内圈相接。钢性部件5和钢性部件4可以不直接相接，而是通过一连接部件6相接。只要是能够以该限位凸起1为着力点，由远端向近端，对轴承内圈2沿轴施加径向作用力的结构，均可实现本发明所预期的目的。
作为一种实施方式，也可以在凸起挡块或者凸起挡环(即限位凸起1)与轴承内圈2之间，设一弹性部件(比如弹簧)作为作用力传导部3的一种实现方式。该弹性部件两端，分别与限位凸起和轴承内圈相接。或者，该弹性部件只是作为作用力传导部的一部分，与其他钢性部件一起，共同构成作用力传导部。比如，该弹性部件一端与该限位凸起相接，另一端与一过盈配合装配与轴上的钢性环相接，该过盈配合钢性环与轴承内圈相 接。以该限位凸起为着力点，实现对轴承内圈的限位。
作为一种实施方式，可以在限位凸起与轴承内圈之间安装一个两瓣对开的钢性环，对开的钢性环之间设计螺纹孔，以将对开的两瓣连接成整圆，同时在钢性环上设计轴向的螺纹孔。钢性环的内径与轴形成间隙配合，以实现钢性环可以在轴上移动，同时保证钢性环的外径不大于轴承内圈的外径，以保证钢性环不影响轴承外圈和滚子的安装和拆卸。
在轴承内圈安装之后，可以安装对开两瓣的钢性环，用螺栓把对开的两瓣连接成整圆之后。在钢性环螺纹孔内拧入内六角平端紧定螺钉，拧入紧定螺钉，直至紧定螺钉抵住轴承内圈，此时继续拧入紧定螺钉，将会使钢性环向轴端方向移动，直至该钢性环与限位凸起抵接，比如，该钢性环内的半通槽和轴上的挡块完全顶紧，即实现轴承内圈的完全固定。此时在紧定螺钉上安装垫圈和螺母，即实现轴承内圈的限位固定。
在以上的方案中，也可以在轴承内圈和钢性环之间增加安装一个过盈环，安装完轴承之后，安装过盈环，过盈环靠紧轴承，此时，让紧定螺钉抵住过盈环，实现对轴承内圈固定的冗余机械固定。当然，本领域技术人员可知，在其他实施方式的基础上，增加过盈环，对实现本发明的目的也是有利的。比如，抵靠轴承内圈设置一过盈环(即钢性部件4)后，在该过盈环和轴上的限位凸起之间，设置钢性部件5，并将该钢性部件5通过螺栓固定到该过盈环上。此情况下的钢性部件5可以与轮轴长轴相适应的弧形钢块。在轴上的限位凸起为若干个凸块时，该弧形钢块可以是与限位凸起的个数相适应的若干块，在每个限位凸块与过盈环之间都设独立的弧形钢块；也可以是弧形钢块的个数少于限位凸起的个数，也就是说，有相邻的若干限位凸块与过盈环之间的弧形钢块是一体的。在轴上的限位凸起为凸环时，该弧形钢块的个数可以根据实际需要选择。
对于凸起挡块的设计可以有多重方案，除了所述方形挡块外，也可以是圆弧形，或者不是分散的挡块，设计成整圈的挡圈。钢性环上通槽和半通槽的形状也可以对应变形。
尽管已参照优选实施例表示和描述了本发明，但本领域技术人员应该理解，在不脱离由权利要求限定的本发明的精神和范围的情况下，可以对这些实施例进行各种修改和变换。
