注: 组装前,将 4C-4030 螺纹锁固胶 涂抹在螺栓螺纹上。

(1) 28 只螺栓的扭矩 ... 1800 ± 200 N·m (1320 ± 150 lb ft)

(2) 2 只管塞的扭矩 ... 80 ± 10 N·m (60 ± 7 lb ft)

(3) 组装前,将 4C-4030 螺纹锁固胶 涂抹在 12 个螺栓螺纹上。

(4) 组装前,将 4C-5599 防咬合剂 涂抹在 6 个定位销配件的内径和外径上。

(5) 组装时,必须清洁和干燥橡胶曲面密封圈和与密封圈接触的所有表面。 安装前,在金属密封的接触表面上涂抹一薄层 6V-4876 润滑剂 。 该密封的组装必须与孔相符。 胶曲面密封圈不得有凸起。 不得扭曲胶曲面密封圈。

(6) 根据需要,使用 7Y-0808 垫片 来调整盖和齿圈之间的间隙 (C) :

(C) 间隙 ... 1.0 至 2.6 mm (0.04 至 0.10 in)
数量 ... 1
垫片厚度 ... 1.6 (0.06 in)

(7) 将 4C-5599 防咬合剂 涂抹在 2 个专用圆锥滚柱轴承内环的内径和外径上。

(8) 将 4C-5599 防咬合剂 涂抹在 2 个专用圆锥滚柱轴承外环的内径和外径上。

(9) 组装前,将 4C-4030 螺纹锁固胶 涂抹在两个内六角头调整螺钉的螺纹上。 安装内六角头调整螺钉,需与盖表面平齐。

(10) 组装前,将 1U-8846 垫片密封胶 涂抹到齿圈的表面上。

注: 使用下列步骤调整轴承的预加载荷:

  1. 在专用圆锥滚柱轴承内环上放置 10000 kg (22050 lb) 重的负载 (13) 。

  1. 转动壳体 (14) 以落座锁定轴承。

  1. 将负载 (13) 降低至 3700 ± 370 kg (8160 ± 815 lb)。

  1. 测量马达壳体顶面和轴承内环之间的距离 (G) 。

  1. 测量连接器齿轮 (11) 的步长 (F) 。

  1. 根据需要,使用垫片 (12) ,以便在锁定轴承和连接齿轮 (11) 之间获得正确的间隙。 使用下表 1 计算垫片的总厚度:

    表 1
    测量值     公差    
    (G) − (F)    
    ± 0.10 mm (± 0.004 in)    

注: 如果需 2 片垫片 (12) ,则靠近连接器齿轮处安装最薄的垫片。
