Wiper motor gears

Wiper motor gears Applications and Precision Gear Manufacturing
Automotive windshield wipers consist of an electric motor, reducer, linkage mechanism, wiper arm pivot shaft, and wiper blade assembly. Their primary function is to clear rain, snow, and dust from the windshield that obstruct driver visibility.
Vehicle wipers are configured as either manual speed adjustment or automatic speed adjustment types. Manual wipers adjust wiper speed through different gear positions based on rainfall intensity. Automatic wipers use body sensors to detect rainfall and adjust wiper speed steplessly. The wiper's power source is the electric motor — the heart of the entire wiper system. It uses DC drive and is typically integrated with the worm gear mechanical assembly as a single unit.
The worm gear mechanism reduces speed and increases torque, with the output shaft driving the linkage mechanism that converts continuous rotary motion into left-right oscillating motion. UNITECH-GEAR focuses on plastic worm gear drive design and manufacturing, with worm gears featuring high torque transmission, precise stability, wear and fatigue resistance, and excellent durability.
