How to Adjust The Torque of An Electric Screwdriver

Electric screwdriver, as an indispensable fastening tool in the production and assembly process, has been widely used along with the global popularization of industry 4.0 automatic production line. However, as the core assembly tool of precision machining and machining, the precision and torque screwdriver is very important. Today, I'd like to share with you some practical ways to improve your electric screwdriver by adjusting the torque.

How to Change torque screwdriver

• The principle of adjusting torque is composed of motor, gearbox and clutch. These three parts work together to properly adjust the torque value.
• If you want to adjust the torque to the right value, first calculate the required torque. The power generated by the output shaft of the electric screwdriver motor is rotating. 
• As long as the motor rotates, it will generate a rotating force, which is the torque output of the motor. The torque value is obtained by calculating the ratio of gears of different sizes by the reducer. Among them, in the case of keeping big teeth unchanged and motor teeth increasing, the gear ratio will be smaller. And vice versa. (For example, Pinion with big gear at the same engine speed, pinion with big gear, the output torque is greater, faster acceleration, but the maximum speed is smaller)
• Generally speaking, the smaller the tooth ratio is. The speed of the electric screwdriver will increase, but the torque will decrease. The faster you rotate, the greater the torque.

• The smaller the tooth ratio is, the faster the electric screwdriver turns, but the smaller the torque is.

Then through the power screwdriver clutch device, torsion spring expansion and contraction process to finally reach our ideal electric screwdriver torque value output range. Electric screwdriver torque adjustment ring is to play a stretch torque spring will increase the torque or down the role.
