In other embodiments, the elastic structure 18, the radial hole 22, the dimension measuring instrument mounting portion 38, and the dial gauge 14 may also be set to other numbers, but must satisfy the elastic structure 18, the radial hole 22, and the size measuring instrument mounting portion. The number of 38 and the dial gauge 14 are the same, and the number can simulate a circle, so that the dial gauge 14 of the measuring tool 10 can be used to reflect the variation of the diameter of the envelope circle of the measured object, thereby obtaining the measured value. The envelope diameter of the object.
[0028] 下面将参考此图来详细说明使用本发明的测量工具 10的具体测量方法。  [0028] A specific measurement method using the measuring tool 10 of the present invention will be described in detail below with reference to this figure.

The bearing assembly includes a cylindrical roller bearing 42, a shaft 44, a bearing compression nut 45, and a spacer 52 that is captured between a shoulder of the shaft 44 and the bearing 42. The cylindrical roller bearing 42 includes a bearing inner ring 46, a bearing outer ring 48, and a cylindrical roller (not shown) that is held between the bearing inner ring 46 and the bearing outer ring 48 by a cage. The shaft 44 has a journal 50 for mating with the cylindrical roller bearing 42. The spacer 52 defines the relative positional relationship of the bearing 42 and the journal 50 in the axial direction. By changing the thickness (axial dimension) of the spacer 52, the bearing clearance can be changed. Conversely, if a desired bearing clearance is determined, this desired bearing clearance can be achieved by varying (thinning or thickening) the thickness of the spacer 52.
[0030] 所述测量方法包括:  [0030] The measuring method comprises:
[0031] 1、 将测量工具 10组装好, 即将三个千分表 14分别安装至圆环 12的对应的尺寸 [0032] 2、 将一圆柱形基准校准块插入测量工具 10, 以使得校准块的外圆柱面与弹性 结构 18的圆弧形内表面 20抵触, 将三个千分表 14调零校准, 然后移除校准块。 [0031] 1. The measuring tool 10 is assembled, that is, the three dial gauges 14 are respectively mounted to the corresponding dimensions of the ring 12. [0032] 2.

[0033] 3、 将去除轴承外圈 48的圆柱滚子轴承 42与轴 44的轴颈 50配合后放入测量工具 1 0内, 使得轴承滚子与弹性结构 18的圆弧形内表面 20接触, 其中这个配合结构中 的隔圈的厚度是已知的; 然后转动轴承 42, 当三个千分表 14的读值变化趋势一 致后, 找出轴承滚子最高点的读值, 并据此得到压紧后圆柱滚子的包络圆直径 , 其中该包络圆直径与轴承外圈 48的内径的差便是圆柱滚子轴承 42的游隙。 其 中, 测量工具 10的内径和校准棒的外径由轴承的设计值决定, 轴承外圈 48的内 径是已知的。  [0033] 3. The cylindrical roller bearing 42 that removes the bearing outer ring 48 is fitted into the journal 50 of the shaft 44 and placed in the measuring tool 10 so that the bearing roller contacts the circular arc-shaped inner surface 20 of the elastic structure 18. Wherein the thickness of the spacer in the mating structure is known; then the bearing 42 is rotated, and when the reading values of the three dial gauges 14 are consistent, the reading of the highest point of the bearing roller is found, and accordingly The diameter of the envelope circle of the cylindrical roller after compaction is obtained, wherein the difference between the diameter of the envelope circle and the inner diameter of the bearing outer ring 48 is the clearance of the cylindrical roller bearing 42. The inner diameter of the measuring tool 10 and the outer diameter of the calibration bar are determined by the design value of the bearing, and the inner diameter of the bearing outer ring 48 is known.
[0034] 通过该测量工具测出圆柱滚子轴承 42此吋的游隙之后, 与预期游隙相减, 可得 出需要的游隙变化量。 根据配合面轴颈的锥度比 1 : n即可得出对应上述游隙变 化量的隔圈厚度的变化量 (例如其厚度减薄或加厚的量) 。 因此, 只要对隔圈 的厚度进行相应变化, 圆柱滚子轴承组装之后, 即可实现预期的轴承游隙。  [0034] After the clearance of the cylindrical roller bearing 42 by the measuring tool is measured, the expected clearance is subtracted, and the required amount of change in the clearance can be obtained. According to the taper ratio of the matching journal, the ratio of the thickness of the spacer (for example, the thickness is reduced or thickened) corresponding to the change of the above-mentioned clearance is obtained. Therefore, as long as the thickness of the spacer changes accordingly, the expected bearing clearance can be achieved after the cylindrical roller bearing is assembled.
[0035] 综上所述, 本发明提出一种圆柱滚子轴承游隙测量工具及其测量方法, 通过一 个带弹性的装置得出圆柱滚子轴承压进轴颈后滚子的包络圆直径, 从而控制轴 承的径向游隙。 该测量工具包括一圆环、 若干千分表及基准校准块, 圆环内均 匀设置若干结构相同的弹性结构, 圆环上对应每个弹性结构设置一供千分表的 测杆插入的径向孔。 圆柱滚子轴承配合在轴颈上, 轴承压进后, 径向游隙会减 小, 将轴承放入圆环内使得轴承滚子与弹性结构内表面抵触, 千分表测出弹性 结构在径向上的弹性变量值, 即可得出压进后轴承滚子包络圆直径, 与轴承外 圈内径的差便是游隙。 本发明的测量工具相对精准, 制作简单且实用, 易于推 广应用, 而且测量方法简单方便, 易于实现, 能有效控制轴承游隙, 从而提升 轴承使用寿命。  [0035] In summary, the present invention provides a cylindrical roller bearing clearance measuring tool and a measuring method thereof, and an elastic device is used to obtain an enveloping circle diameter of a cylindrical roller bearing pressed into a journal rear roller. , thereby controlling the radial play of the bearing.
