1.Spur Gear Description

Within the field of miniaturisation, spur gears are core micro-transmission components characterised

by their diminutive dimensions (typically with modules ranging from 0.1 to 1mm) and demanding precision requirements,

finding extensive application in precision micro-devices.

2.Key Features

Characterised by compact dimensions and lightweight construction, these gears achieve tooth profile precision

to IT5-IT7 grades with excellent transmission smoothness. Their advantages include enabling precise speed

and torque transmission within confined spaces, offering rapid response times and low energy dissipation.

They demonstrate strong compatibility with components such as miniature motors and bearings,

facilitating the integration of compact micro-transmission systems.

3.Working Principle

Precision machining techniques (e.g., wire cutting, precision gear hobbing, laser engraving) ensure tooth profile accuracy

and pitch uniformity. When meshing with micro-actuators (e.g., micro-motor shafts), the minimal tooth contact clearance

and high-precision tooth profile engagement enable low-noise, low-vibration power transmission, meeting micro-devices'

demands for transmission precision and compact spatial requirements.

4.Applications

Focus drive systems in smartphone cameras, joint drive gears for micro-robots, fine-adjustment transmission mechanisms

in drone gimbals, micro-transmission gears in medical endoscopes, and counting/adjustment gears in precision instruments.
