1. The overall planning is fair, because the electric wrench is manually operated,? Therefore, it is necessary to consider reducing the volume and weight of wrench in planning. For this reason,? The stepping motor with small volume, convenient torque wrench and easy control of torque and speed is selected as the power equipment. The reduction equipment adopts the planetary gear organization with compact structure and large transmission ratio.

2.传感器规划的奇妙性

2. The wonder of sensor planning

扭矩传感器的设计对电动扳手的使用功能关重要。由于扳手头正在旋转，因此，不能直接将应变计粘贴在其上，否则导线将缠绕在扳手头上并被折断。如果选择了其他旋转轴扭矩传感器，扳手体积过大，成本高，精度低。

The design of torque sensor is very important to the function of electric wrench. Since the wrench head is rotating, the strain gauge cannot be directly pasted on it, otherwise the wire will be wound on the wrench head and broken. If other rotating shaft torque sensors are selected, the wrench is too large, high cost and low precision.

3.功课原理的科学性

3. The scientificity of the principle of homework

电动扳手主要由微机控制系统、步进电机、两级行星齿轮组织、外壳、扭矩传感器和扳手头号组成。当步进电机移动时,中间轮动弹带动高速级行星齿轮组织,该组织的另一个中间轮（齿圈）与壳体固定，扭矩由系杆传输到低速行星齿轮组织的中间轮,该组织的另一个中间轮(齿圈)与传感器相连，并通过传感器固定在外壳上。

The electric wrench is mainly composed of microcomputer control system, stepping motor, two-stage planetary gear organization, shell, torque sensor and wrench head. When the stepping motor moves, the intermediate wheel moves to drive the high-speed planetary gear organization. The other intermediate wheel (ring gear) of the organization is fixed with the shell, and the torque is transmitted to the intermediate wheel of the low-speed planetary gear organization by the tie rod. The other intermediate wheel (ring gear) of the organization is connected with the sensor and fixed on the shell through the sensor.
