Miniature One Way Clutch

Miniature One Way Clutch

Product catalog summary

Overview: The document provides detailed information about the Koyo miniature one-way clutch, highlighting its design, functionality, and applications. It emphasizes the clutch's suitability for compact designs, its ability to prevent creep, and its efficiency in reducing heat generation and wear.

Specifications: The clutch is designed for compact equipment, utilizing a thin steel sheet for the outer ring (drawn cup) to minimize size and weight. It features excellent grease retention, allowing for a wide range of operating temperatures without the need for grease replenishment under normal conditions.

Functionality: The clutch operates by engaging rollers with a cam on the drawn cup when the shaft rotates clockwise, locking the mechanism. In counterclockwise rotation, the rollers disengage, allowing the shaft to rotate freely. This design prevents creep even with less accurate plastic housing surfaces.

Installation and Maintenance: The clutch is easy to install, requiring no special fixing devices, and can be directly press-fitted into plastic housings. It is designed to operate without the need for frequent maintenance, thanks to its pre-packed grease.

Applications: The clutch is used in various office automation equipment such as printers, copiers, and facsimiles. It is also applicable in industrial machines like sewing machines and vending machines. The document notes that the clutch itself cannot handle radial and moment loads, necessitating additional bearings for such conditions.

Technical Details: The document includes detailed tables of dimensions, torque capacities, and recommended tolerances for shaft and housing dimensions. It specifies the use of carburized steel for the drawn cup and provides guidelines for shaft surface hardness and torque ratios.

Contact Information: The document lists contact details for Koyo's offices worldwide, including locations in Japan, the USA, Canada, Mexico, and several other countries.
