The function of worm gears in automobiles
Precise Adjustment: The helical structure of the worm gear enables fine, precise angular rotation, and when paired with a worm wheel, it delivers high‑precision position control. For example, in automotive applications such as electric seat adjustment and precision window‑raising/lowering modules, it can accurately regulate both the position and speed of seat and window movements.
