Sprocket ・Pin gear drive
A sprocket is a type of gear and is also called a chain wheel.
A mechanical element that can transmit the rotation of a shaft to a chain or the tension of a chain to a shaft.
Types depend on use of a hub: Type A (flat type), Type B (single hub), Type C (dual hub).
High-strength, corrosion-resistant series are available for use in a variety of situations.
※Sprockets for Plastic modular chains, Top chains and Plastic block chains can be found on the product page for each chain.
What's New / Product Information
Features
- ・When used for drive chain transmission, a large reduction ratio can be achieved by combining the number of teeth. (Usually up to 1:7 )
- ・Choose from a wide range of lineups, including pilot bore products, finished bores and additional bore finishings. (Steel, stainless steel, engineering plastic, surface treatment, etc. )
- ・A range of materials and specifications are available to suit your application.
- ・Sprockets for pin gears with special tooth profiles can be used in combination with attachment chains or pin rack/pin wheel for rotating and linear drive applications instead of power transmission applications.
Construction
RS sprockets are manufactured in four types in conformance with JIS standards.
| Model code | A Type (flat plate ) |
B type (Single hub ) |
C type (Dual hub ) |
SD Type (single dual ) |
|---|---|---|---|---|

|
| Multi-strand Heavy Duty Chain (Super-H, RS-HT, etc.) Note 1 | For using two single-strand chains at the same time | |||
| HB type | HC type | |||
| Usage by structure | Used when mounting on a rotating body, such as the center member of Torque Limiter. | Most versatile use. | For use with large driven sprockets or when key surface pressure is insufficient with B type. | For using two single-strand chains at the same time. |
Notes
1.The total tooth width (transverse pitch) of multi-strand Heavy Duty chains (HB/HC types) differs from the standard.
Locking system to shaft
The following three types of bores for attaching the sprocket to a shaft are available for RS sprockets.
