A worm gear is a mechanical component used in slack adjusters to provide precise angular positioning and self-locking capability in automotive braking systems.
Commonly used trade names and technical identifiers for Worm gear.
This component is used in the following industrial products
A mechanical device in brake systems that automatically compensates for brake lining wear to maintain proper clearance between brake shoes and drums.
A mechanical system consisting of two or more gears meshed together to transmit motion and torque between rotating shafts.
A mechanical device that converts rotational steering wheel input into linear motion to control vehicle wheel direction.
"Testing the Worm gear now; the technical reliability results are within 1% of the laboratory datasheet."
"Impressive build quality. Especially the technical reliability is very stable during long-term operation."
"As a professional in the Motor Vehicle Manufacturing sector, I confirm this Worm gear meets all ISO standards."
Worm gears provide three critical advantages for slack adjusters: high reduction ratios in compact spaces, precise positioning capability for accurate brake adjustment, and inherent self-locking that maintains adjustment without additional locking mechanisms.
Primary maintenance involves periodic lubrication with high-pressure grease (typically every 50,000 km or during brake service), inspection for wear patterns, and backlash measurement. Most automotive applications use sealed, lubricated-for-life designs.
Self-locking occurs when the lead angle of the worm is less than the friction angle between the materials. This creates sufficient friction to prevent the worm wheel from back-driving the worm, effectively locking the position when input torque is removed.
