Tips: How to adjust torque of brushless electric screwdriver?
- Torque adjustment design of the brushless electric screwdriver is mainly composed of motor, gear box and clutch device. Only when the three parts are proportioned together, can the screwdriver be adjusted to proper torque value.
- To adjust to the proper torque value, first calculate the required torque value. Through the reduction gear box, use different sizes of gears for different ratios, and then calculate, and finally a torque value can be obtained. Among them, in the case of keeping the big gear unchanged and the motor gear enlarged, the gear ratio will become smaller. Otherwise, it will increase. Generally, the smaller the gear ratio, the faster the brushless electric screwdriver. In this time, the torque will become smaller. The faster the rotation, the greater the torque.
- Adjust torque through clutch device. Brushless electric screwdriver has a torque adjustment ring. It can adjust torque by extending and retracting the torsion spring.
