Plastic Worm Gears

Crafted by Feida Machinery factory,plastic worm gears are critical components in plastic worm drive systems,paried with worms ( screw-like shafts) to achieve high reduction ratios,self-locking property, and compact design.

The typical engineering plastics used for our products include nylon,PEEK,POM,which all come from original manufacturers and have material certifications.

Application

Plastic worm gears are common in consumer goods,including household appliances,printer feed mechanisms,automatic door drives,food processing machinery,medical devices,toys,smart home devices, lab instruments,etc.

FAQ

Why choose plastic materials?

Compared to traditional bronze ,They have significant advantages as follows:
Self-lubricating:Many plastics(e.g., POM,Nylon) have low friction coefficients and can operate without lubrication,which prevents seizing or galling that can occur with metal gears when dry.
Low noise:Plastic’s inherent ability to absorb vibrations allows for lower operating noise.
Low cost:Plastic gears can be mass-produced quickly and cheaply using injection molding,which eliminates complex and costly machining processes.
Corrosion resistance &light weight:Plastics are resistant to moisture,weak acids,alkalis and the other corrosive agents.Additionally,their  low density helps reduce rotational inertia,allowing mechanisms to start and stop more responsively.

What should be considered in the design process?

Material pairing: Plastics worm gears must be paired with steel worms.The plastic parts ensure wear resistance and noise reduction, while the metal parts provide stength.
Thermal management: During design, contact stress and temperature must be strictly calculated, and operating temperatures are typically required to remain below 120℃.
