After the electric torque wrench motor is decelerated by planetary gear mechanism, the power is transmitted to the impact head. The impact head and two protruding heads drive the rotating shaft through the wrench to complete the power output. When the torque wrench is used for a period of time, its output power decreases. With the increase of wrench usage time, the output power will continue to decline until it can not work. How should we deal with this situation?

　　通过对电动扭矩扳手的解体观察，人士发现，所使用的扭矩扳手，其扳手轴的工作面磨损严重。磨损工作面是与原工作面成45度角的斜面。冲力分散后，扳手内件的受力也发生了变化。通过反复的观察和检查，电扳手失效的主要原因是轴的工作表面磨损严重。

　　Through the observation of the disintegration of the electric torque wrench, professionals found that the working surface of the wrench shaft was worn seriously when the torque wrench was used. The worn working face is an inclined plane with an angle of 45 degrees from the original working face. When the impulse is dispersed, the force acting on the wrench internals also changes. Through repeated observation and inspection, the main reason for the failure of electric wrench is the serious wear of the working surface of the shaft.

　　为了延长电动力矩扳手的使用寿命，有必要其磨损问题。如果能这个问题，就能冲击头磨损问题。更换整体杠杆轴拆卸，杠杆轴工作面可拆卸。使用一段时间后，可根据磨损情况进行更换。可移动工作面可单独选择合适的材料，通过合理的加工工艺，达到较高的机械性能。

　　In order to prolong the service life of electric torque wrench, it is necessary to solve its wear problem. If this problem can be solved, the problem of impact head wear can be solved. Replace the integral lever shaft and disassemble. The lever shaft working face can be disassembled. After using for a period of time, it can be replaced according to the wear condition. Movable working face can select suitable materials independently and achieve higher mechanical properties through reasonable processing technology.

　　建议电动力矩扳手选用高碳钢，淬火回火热处理工艺。这样，加工后的工作面既有较高的硬度又有一定的韧性，使其在冲击过程中不会断裂，并且可以大批量加工，一次加工就可以满足长期更换使用的要求，非常方便。从而了77779193永利首页网址输出功率降低的问题。

　　Experts recommend high carbon steel for electric moment wrench, quenching and tempering heat treatment process. In this way, the working face after processing has both higher hardness and certain toughness, so that it will not break in the impact process, and can be processed in large quantities, one processing can meet the requirements of long-term replacement and use, very convenient. Thus, the problem of reducing the output power of the electric wrench is solved.
