Worm Gear Reducers

Feida worm gear reducers are one of the important types of speed reduction transmission devices. They achieves power transmission through the meshing of worm gears and worm shafts, and belongs to the form of staggered shaft transmission. They are usually used in transmission systems where the two shafts are perpendicular to each other, featuring a high requction ratio(5:1 to 100:1 in a single stage), compact design, smooth operation, and self-locking function.

Basic Structure

Worms: Transmission components with a helical tooth shape, usually installed on the input shaft.
Worm gears: Driven parts that mesh with the worm and are usually installed on the output shaft. The worm gear ring is generally made of non-ferrous metal materials with good wear resistance, while the core can be made of cast iron or steel to balance strength, wear resistance and economy.
Housings: Used to support and fix each component, while storing lubricating oil and protecting the internal transmission mechanism.
Lubrication System: Very important for reducing friction, minimizing wear, and controlling temperature rise. Common lubrication methods include oil-bath lubrication, splash lubrication, and forced-circulation lubrication.

Working Principle

Power source → Input shaft → worm → worm gear → output shaft → working mechanism

Material Selection

Worm Material: A Worm is usually made of high-quality alloy steel or carbon steel and undergo heat treatments such as quenching and tempering, surface quenching or carburizing and quenching according to working conditions to enhance the hardness and wear resistance of the tooth surface.
Worm Gear Material: Worm gear rings often use copper alloy materials such as tin bronze and aluminum bronze. Copper alloys have good anti-friction, wear resistance and anti-adhesion properties, and are suitable for use in conjunction with steel worm gears.
Housing Material: The housing is often made of cast iron, aluminum alloy or welded steel structure. The cast iron housing has good rigidity, vibration damping performance and processing performance. The aluminum alloy housing is relatively light in weight and has good heat dissipation performance, making it suitable for equipment with weight requirements.

Application

Conveying Equipment

Used in conveyors, lifting conveying equipment, and material handling equipment to reduce motor speed and increase output torque, enabling the conveyor belt or other actuators to operate at an appropriate speed

Automated Machine

Used In packaging equipment, indexing mechanisms, actuators and small-scale automated devices to provide stable low-speed power output and meet specific spatial layout requirements.

Lifting and hoisting equipment

Used in some lifting and hoisting auxiliary mechanisms. However, when it comes to personnel safety or the retention of heavy objects, it cannot rely solely on its possible self-locking performance. It must be combined with brakes, limit devices and other safety measures.

Valves and actuators

Used in industrial valve drives, rotary actuators and other equipment to to achieve a large reduction ratio and high output torque, and meet certain holding and positioning requirements.

Machine tools and other mechanical equipment

Used in some machine tool auxiliary drives, turntable drives and special machinery to meet the requirements of low-speed drive, steering layout or compact installation, etc.
