图 1g02006034

(A) 0.20 ± 0.05 mm (0.008 ± 0.002 in) 的所需间隙尺寸

(1) 柱塞缸

(2) 中心销

(3) 弹簧

(4) 垫片

注: 尺寸 (A) 是垫片 (4) 和中心销 (2) 的端部之间所需的间隙。

此步骤将确定获得尺寸为 (A) 的间隙所需的垫片厚度。

  1. 将弹簧 (3) 从油缸筒 (1) 上拆下。

    (B) 测得尺寸

    (1) 柱塞缸

    (2) 中心销

    (4) 垫片

    (5) 轴

    (6) 挡圈

    (7) 配流盘

  1. 将旋转总成安装到壳体中。 参考图 2。

  1. 向轴 (5) 施加 650 至 675 N (145 至 150 lb) 的拉力,以便抵住挡圈 (6) 座合旋转总成。

  1. 平行于马达壳体表面定位配流盘 (7) 的表面。

  1. 测量配流盘 (7) 的表面与马达壳体表面之间的尺寸 (B) 。

  1. 从测得尺寸 (B) 减去间隙尺寸 (A) 。 这就是垫片 (4) 的厚度。

    注: 测量值(B)- [0.20 ± 0.05 mm(0.008 ± 0.002 in)] = 垫片厚度

    注: 请参阅技术规格, "马达旋转总成(制动器冷却)",了解要使用的正确垫片。

    注: 仅使用一个垫片 (4) 获取尺寸 (A) 。

  1. 拆下柱塞缸 (1) 并安装弹簧 (3) 和步骤 6 中确定的垫片 (4) 。
