Made in Japan
Manufacturer: Fukuda Seiko
Model: FE 80 Series : FE 8072 Z 25/ FE 8000 Z

Developed by GMN, which has been dealing with machine component parts for more than 100 years, this is a lightweight, space-saving, and high-torque one-way clutch. A mechanism of the ring fastening part called a sprag controls the direction of rotation.

Use

Printing Machinery
Conveyor
E-bikes (electrically power assisted bicycles)
Compressor
Winch
Generators
Emergency power supply equipment and fire doors
Wheelchair

Features

Suggestions for backstops, indexes, and overrunning
Space-saving and high torque
High-speed swivel motion
High-precision positioning
Minimal moment of inertia
Uniform load distribution due to individual sprag movements
High design freedom with various options: with inner and outer rings, with axle reception, with keyway, with lubrication and seals

Summary

A one-way clutch is a clutch mechanism that transmits power in only one direction, and GMN uses a sprag-type mechanism.

Idle direction Power transmission direction

The friction force generated when the uniquely designed sprag is upright around the entire circumference controls the direction of rotation. Since a static friction force is generated around the entire circumference, both high torque and space saving are achieved.

The slight rotation of the tilt angle of δ minutes makes the splug stand upright.

There are two types of spring structures that fix the splugs, Z type and M type, and use the M type for applications where the angular frequency (angular frequency) is greater than 10 Hz.

You can choose the best clutch from a variety of designs + options.
