D7G2 Track-Type Tractor Power Train Caterpillar


Track Tension - Test and Adjust

Usage:

D7G 7MB

------ WARNING! ------

润滑脂有很高的压力。

润滑脂在压力下喷出卸压阀能够穿透身体,造成伤亡。

不要通过泄压阀来观察润滑脂是否溢出。 应观察履带或履带调整油缸来查看履带是否松动。

只要转一圈,以便把卸压阀松开。


------ WARNING! ------

为防止人身伤害,不得目视检查通风孔或阀处的润滑脂或机油是否流出。 卸掉履带的张力前,确保通风孔是干净的。 从前支重轮架观看其移动情况。


介绍

必须维持履带的下垂量。

以下测试步骤用于核实履带的下垂量是否符合规定的限制。

测试步骤

  1. 把机器往前移动大约机器长度的两倍。 不使用制动器使机器停止。

    注: 在工作场地的操作条件下测试履带。 如果工作条件要求存在填料,不得去除履带的填料。

  1. 测量间隙 (A) 。 缓冲杆挡块前部和平衡杆安装板的后表面之间的间隙 (A) 。

注: 如果间隙 (A) 小于 3.18 mm (0.125 in),不要紧固履带。

履带的调整步骤

(1) 加注阀和安全阀的扭矩 ... 35 ± 7 N·m (25 ± 5 lb ft)

对于正确的履带调整,遵照此步骤。

注: 在工作场地的操作条件下调整履带。 如果工作条件要求存在填料,不得去除履带的填料。

  1. 把机器往前移动大约机器长度的两倍。 不使用制动器使机器停止。

  1. 移除阀门盖板。

    履带处在完全张紧的位置。

  1. 用加注阀加注多用润滑脂 (MPGM),以将引导轮向机器前部移动。 移动引导轮,直到履带处于完全张紧位置。 在与引导轮轴承组件前表面平齐的履带支重轮架上作标记 (B) 。

  1. 在履带支重轮架标记 (B) 后面 13.0 mm (0.51 in) 处作标记 (C) 。

    履带松动

  1. 打开安全阀,使引导轮向后移动,直到引导轮轴承组件的前表面在标记 (C) 之后。

    注: 必须前后移动机器以将引导轮移回正确的位置。

  1. 关闭安全阀。

    履带的正确调整

  1. 用加注阀加注多用润滑脂 (MPGM),再次向前移动引导轮,直到引导轮轴承组件的前表面与履带支重轮架的标记 (C) 平齐。

  1. 安装阀门盖板。

  1. 在机器的另一侧,重复同样的步骤。
