飞轮端面跳动(轴向偏心度)

表 1
所需工具    
零件号     零件名称     数量    
8T-5096     千分表总成     1

    检查飞轮的端面跳动

  1. 请参阅图 1 并安装千分表。 在读取千分表上的读数之前,在曲轴上施加一个同方向的力。 要想消除曲轴端隙。

  1. 设定千分表读数为 0.0 mm (0.00 in)。

  1. 以 90 度为间隔转动曲轴,读取千分表的读数。

  1. 记录所有四个测点的测量值。 在飞轮直径为 25.4 mm (1.0 in) 时,在所有四个点测得的高低值之差不得高于 0.13 mm (0.005 in) 的跳动量。

检查飞轮的镗孔跳动

(1) 7H-1945 握杆

(2) 7H-1645 握杆

(3) 7H-1942 千分表

(4) 7H-1940 万用附件

  1. 安装 7H-1942 千分表 (3) 。 对 7H-1940 万能固定架 (4) 进行调整,以使千分表接触到飞轮。

  1. 设定千分表读数为 0.0 mm (0.00 in)。

  1. 以 90 度为间隔转动曲轴,读取千分表的读数。

  1. 记录所有四个测点的测量值。 在所有四点测得的高低值间的差值不得超过飞轮最大允许端面跳动(径向偏心度)的以下数值。

    飞轮 ... 0.13 mm (0.005")

    飞轮离合器导向轴承孔

  1. 使用前述步骤,测量导向轴承孔跳动(偏心度)。

  1. 飞轮上的导向轴承孔的摆差(偏心度)不应超过以下数值:

    飞轮 ... 0.13 mm (0.005")
