Worm Gear advantage
Noise
In applications where noise is a concern, worm gears are ideal. Unlike other gears that produce high pitched whines at high speeds, worm gears are exceptionally quiet. Worm gears are often used in public places because of their noiseless operation.
Fast Stopping
The unique design of worm gears gives them the ability to stop quickly; this makes them the right choice for the operation of elevators. Though they can’t make up the complete braking system, they work well with other braking system components as a safety measure.
Space
The main reason worm gear are installed in many applications is the small amount of space they require. Their compact design makes them a perfect addition to applications that need efficiency but have limited space.
Shock Absorption
All worm gears are made of two different metals, with a harder metal used for the worm and a softer one used for the wheel. This design enhances a worm gear’s ability to absorb shock loads that are found in construction equipment and other applications that have heavy loads.
Torsion
Off road and construction vehicles require different amounts of torque to be delivered to each wheel. The need for a variation in torque is due to the terrain that the wheels of the vehicles have to traverse. Worm gears enable these types of vehicles to maneuver and drive over uneven ground without the fear of damage.
Tuning
The least complicated worm gears are those that are used to tune stringed instruments. Placed on the head of the instrument, the worm gear allows for easy tuning and adjustments to raise or lower the pitch of a string.

Non-Reversible
Another aspect of worm gears in lifts or elevators is their non-reversibility, which serves as a failsafe braking system should the primary braking system fail.
Conveyor Belts
Worm gears are commonly found in conveying systems due to their single direction motion and ability to lock up when motion stops. When a conveyor shuts down, it has to remain motionless. A worm gear locks in place when motion stops and prevents the conveyor from slipping or moving forward.
Automatic Door Systems
Automatic doors have right and left movement; this has to be stopped when they have moved the necessary distance. The ending or stopping of the door’s motion is achieved with a worn gear.
Automotive Steering Systems
In an automotive steering system, the worm gear connects to the steering wheel through the steering column. The turning of the steering wheel depends on the precise angle of the gear ratio of the worm gear system.
