1.全體規(guī)劃的公道性由于電動扳手是手工操縱東西,?因而規(guī)劃時需要思索減輕扳手體積和分量。為此,?選用體積較小、定扭矩扳手便捷的扭矩和轉(zhuǎn)速易于操控的步進電機作為動力設(shè)備。減速設(shè)備則選用構(gòu)造緊湊、傳動比大的行星齒輪組織。
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.傳感器規(guī)劃的奇妙性
2. The wonder of sensor planning
扭矩傳感器的設(shè)計對電動扳手的使用功能關(guān)重要。由于扳手頭正在旋轉(zhuǎn)，因此，不能直接將應(yīng)變計粘貼在其上，否則導(dǎo)線將纏繞在扳手頭上并被折斷。如果選擇了其他旋轉(zhuǎn)軸扭矩傳感器，扳手體積過大，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.功課原理的科學(xué)性
3. The scientificity of the principle of homework
電動扳手主要由微機控制系統(tǒng)、步進電機、兩級行星齒輪組織、外殼、扭矩傳感器和扳手頭號組成。當(dāng)步進電機移動時,中間輪動彈帶動高速級行星齒輪組織,該組織的另一個中間輪（齒圈）與殼體固定，扭矩由系桿傳輸?shù)降退傩行驱X輪組織的中間輪,該組織的另一個中間輪(齒圈)與傳感器相連，并通過傳感器固定在外殼上。
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.
