High-Efficiency Worm Gears for Smooth Industrial Power Transmission

Established in 1998, Jinjiang Feida Machinery Co., Ltd. has a modern production workshop covering 45,000 square meters and employs 150 people, including over 20 technical staff. Our worm gears are widely sold in China, Europe, the United States, the Middle East, Southeast Asia, and other regions.

The gear usually works with a worm in a worm gear transmission system and features high reduction ratios, compact design, smooth operation, and potential for self-locking.

Working Principle

The worm is usually installed on the driving shaft and is powered by an electric motor or another power source. The worm wheel is installed on the driven shaft. When the worm rotates, its helical teeth continuously engage with the teeth of the worm wheel and cause the wheel to rotate.

Main Parameter

Module: Determines the basic tooth size and is one of the most important parameters.
Number of Teeth: Determines the transmission ratio together with the number of worm starts.
Pressure Angle: Affects tooth loading, meshing performance, and transmission characteristics.
Face Width: Affects its load-carrying capacity.
Number of Worm Starts: Determines the transmission ratio together with the worm wheel tooth count.

Production Flow & Quality Control

Feida's modern production steps include:

Raw Material Selection → Forging → Turning → Gear Hobbing → Heat Treatment → Inspection → Packaging

Feida has obtained ISO 9001:2015 quality management system certification. Rigorous quality control is taken out on every step right from selection of raw material to final packing.

Frequently Asked Questions

Are worm gears always self-locking?

No. Self-locking depends on factors such as the worm lead angle, friction conditions, materials, lubrication, and load.

Why are worm wheels commonly made from bronze alloys?

Worm wheels are often manufactured from bronze or other copper alloys because these materials provide suitable wear resistance and friction characteristics when paired with hardened steel worms. The specific material combination should be selected according to the load, speed, service life, and lubrication conditions.
