Fukuda FE 455 Z FE 400 Z type GMN Clutch
Made in Japan
Manufacturer: Fukuda Seiko
Model: FE 455 Z
FE 400 Z type
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.
