In the main operation system of underground loader, the performance of hydraulic and transmission of hydraulic system directly affects the quality and efficiency of engineering construction, so it is an important content for modern engineering and technical personnel to understand and master its use and maintenance knowledge and elimination technology.

关乎井下装载机变矩器的保养方法我们为您总结以下几点：

Concerning the maintenance methods of torque converter of underground loader, we summarize the following points for you:

①每班工作后，应检查井下装载机变速箱有关机件的结合紧固情况，如有松动，应及时拧紧。

① After each shift, check the binding and fastening condition of the gear box of the underground loader. If it is loose, tighten it in time.

②每工作100h后，拧下变矩器盖上的加油螺帽，用油位尺检查油面高度，油面高度应在油位尺上下刻线之间。测量时，拖拉机应处于水平位置。油量不足时应及时添加。

② After every 100h of operation, screw off the oil nut on the torque converter cover, and check the oil level with the oil level gauge. The oil level shall be between the upper and lower lines of the oil level gauge. When measuring, the tractor should be in the horizontal position. When the oil quantity is insufficient, it should be added in time.

③的润滑油为齿轮油，要注意保持齿轮油的清洁，油中不应有机械杂质，否则会加速齿轮的磨损。加油时，应注意加油工具和加油口的清洁。

③ The lubricating oil is gear oil. Pay attention to keep the gear oil clean. There should be no mechanical impurities in the oil, otherwise the wear of the gear will be accelerated. When refuelling, pay attention to the cleaning of refuelling tools and refuelling ports.

④井下装载机每工作500h左右应清洗变速箱，更换齿轮油。清洗方法如下：井下装载机工作结束后趁热放出赃油，然后加入适量的清洁柴油，拖拉机前进、倒退数次，然后放出柴油，再加入清洁齿轮油。注意不同季节应选用不同规格的齿轮油，冬季用冬季齿轮油，夏季用夏季齿轮油。

④ The gearbox should be cleaned and the gear oil should be changed every 500h. The cleaning method is as follows: after the underground loader is finished, let out the dirty oil while it is hot, then add an appropriate amount of clean diesel oil, the tractor moves forward and backward several times, then let out the diesel oil, and then add clean gear oil. It should be noted that different specifications of gear oil should be selected in different seasons, winter gear oil in winter and summer gear oil in summer.

除此之外定期检查各处油封和衬垫纸板的密封、完好情况，必要时应予更换。更换时，衬垫纸板的厚度应与原来厚度相同以保证正确的轴向间隙，保证井下装载机的正常运行。

In addition, regularly check the sealing and integrity of oil seals and linerboard, and replace them if necessary. When replacing, the thickness of liner board should be the same as the original thickness to ensure the correct axial clearance and the normal operation of underground loader.
