In the main operating system of underground loader, the transmission performance of hydraulic and hydraulic system directly affects the quality and efficiency of engineering construction. Therefore, understanding and mastering its use and maintenance knowledge and troubleshooting technology is an important content for modern engineers and technicians.

關(guān)乎井下裝載機(jī)變矩器的保養(yǎng)方法我們?yōu)槟偨Y(jié)以下幾點(diǎn)：

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

①每班工作后，應(yīng)檢查井下裝載機(jī)變速箱有關(guān)機(jī)件的結(jié)合緊固情況，如有松動(dòng)，應(yīng)及時(shí)擰緊。

① After each shift, check the binding and fastening of relevant parts of the gearbox of the underground loader. If it is loose, tighten it in time.

②每工作100h后，擰下變矩器蓋上的加油螺帽，用油位尺檢查油面高度，油面高度應(yīng)在油位尺上下刻線之間。測(cè)量時(shí)，拖拉機(jī)應(yīng)處于水平位置。油量不足時(shí)應(yīng)及時(shí)添加。

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

③的潤(rùn)滑油為齒輪油，要注意保持齒輪油的清潔，油中不應(yīng)有機(jī)械雜質(zhì)，否則會(huì)加速齒輪的磨損。加油時(shí)，應(yīng)注意加油工具和加油口的清潔。

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 it will accelerate the wear of the gear. When refueling, pay attention to the cleanliness of refueling tools and refueling ports.

④井下裝載機(jī)每工作500h左右應(yīng)清洗變速箱，更換齒輪油。清洗方法如下：井下裝載機(jī)工作結(jié)束后趁熱放出贓油，然后加入適量的清潔柴油，拖拉機(jī)前進(jìn)、倒退數(shù)次，然后放出柴油，再加入清潔齒輪油。注意不同季節(jié)應(yīng)選用不同規(guī)格的齒輪油，冬季用冬季齒輪油，夏季用夏季齒輪油。

④ The gearbox shall be cleaned and the gear oil shall be replaced every 500h of underground loader. The cleaning method is as follows: after the work of the underground loader is completed, release the stolen oil while it is hot, then add an appropriate amount of clean diesel, advance and reverse the tractor several times, then release the diesel, and then add clean gear oil. Note that different specifications of gear oil shall be selected in different seasons. Winter gear oil shall be used in winter and summer gear oil shall be used in summer.

除此之外定期檢查各處油封和襯墊紙板的密封、完好情況，必要時(shí)應(yīng)予更換。更換時(shí)，襯墊紙板的厚度應(yīng)與原來厚度相同以保證正確的軸向間隙，保證井下裝載機(jī)的正常運(yùn)行。

In addition, regularly check the sealing and integrity of all oil seals and liner paperboards, and replace them if necessary. During replacement, the thickness of liner paperboard shall be the same as the original thickness to ensure correct axial clearance and normal operation of underground loader.
