Electric Screwdriver Gearbox

In our daily life, we use tools such as screwdrivers to disassemble something. We manually screw the screws by ourselves and screw them straight into the hole. It’s wrong. Although we can tighten it, this approach will cause damage to some precision instruments.


With the advancement of science and technology, there are many electric screwdrivers on the market that are aiming at maintaining precision instruments. The adjustment function enables users to adjust the torque as needed. It can maintain precision instruments without damaging the screws. However, these electric screwdrivers have the disadvantage of not screwing well or tight. ZHAOWEI micro-drive system can be applied to electric screwdrivers. It has two-stage, three-stage, and four-stage transmission changes available for you to choose from. The reduction ratio, output speed, and torque can be selected based on your specific requirements of the electric screwdriver. Compact structure and high-efficiency help realize the tightening function.

The electric screwdriver needs to feature high torque with compact size. Through the analysis of the functional requirements of the electric screwdriver, a planetary gearbox can be adopted to realize the forward and reverse rotation and adjustment, thus fulfilling tightening and loosening screws.


In terms of safety, safe self-locking can be realized by using the reduction gearbox and the screw rod. If It is detected that the screwdriver is twisted manually, and the internal self-locking structure will automatically open to avoid damage to the motor.


The electric screwdriver has a twist-proof function that evenly rotates to prevent damage to components due to excessive force. If you want to enjoy the fun of disassembling things, then the electric screwdriver will be a good choice. It’s suitable for disassembling quartz watches, cameras, radios, computers, mobile phones, drones, and other conventional household appliances, meeting most daily repair needs.


For electronic DIY enthusiasts, noise could be a big problem. To reduce noise, we carry out displacement coefficient distribution for each gearbox for the electric screwdriver, optimize the calculation of meshing angle, slip rate, and coincidence check to improve efficiency and service life, reduce noise. Meanwhile, finite element analysis technology is adopted to analyze and check the tooth surface strength of spiral teeth and bevel gears, thus improving the stability of the electric screwdriver gearboxes.
