Business Machines and Paper Handling
For over 50 years, Reell has provided enabling technology for business machines and paper handling applications. With industry leading precision and life ratings, Reell wrap spring clutches precisely move paper in copiers, printers, scanners, mail sorters, direct mail and envelop processors, along with currency dispensing in ATMs and point of sale equipment.
Wrap spring technology used in Reell clutches provides the capability to transmit a large amount of torque in a small size. The package size for a given load rating is smaller for electric wrap spring clutches than other clutch technologies such as friction disk, tooth or magnetic particle. It also require less power for a given torque than these other technologies. Mechanical wrap spring clutches require only a small amount force for actuation.
Electric wrap spring technology has very positive engagement characteristics, meaning once the spring has wrapped down, the clutch will bring the system output up to speed in just a few milliseconds. Slip during engagement is virtually eliminated, resulting in the ability to cycle the clutch multiple times per second. Disengagement is also almost instantaneous, even under load. This precision is critical to rapidly and accurately move paper.
Electric wrap spring clutches are ideally suited for critical timing applications requiring consistent, repeatable engagement and disengagement performance. Reell’s patented clutch design limits the effects of wear, so the timing performance remains constant throughout its rated life as opposed to other technologies which see increased timing variation as the load-driving surfaces wear. For high hour and/or input revolution applications, Reell has developed a long-life version, which dramatically extends the life of the clutch.
