High Torque Electric Wrap Spring Clutches

Reell Electric Wrap Spring Clutches

Reell electric wrap spring clutches are engineered to engage and disengage torque on a rotating shaft with precision timing and repeatable performance. Designed for intermittent motion control, these clutches deliver high torque density, fast response, and consistent engagement across millions of cycles.

What Is a Wrap Spring Clutch - How Does It Work?

An electric wrap spring clutch transmits torque using a helically wound spring wrapped around an input and output hub.  When actuated, the spring tightens around the shaft, creating a positive mechanical connection that transmits torque instantly.  When released, the spring unwraps, allowing the shaft to rotate freely.

  • Electric wrap spring clutches work well in applications requiring:

  • Fast, controlled engagement and disengagement

  • Full torque transmission without slip
    Compact integration into high-cycle rotating systems

Not all input-engaging clutches perform the same. While friction clutches rely on surface contact and slip, wrap spring clutches use a self-energizing spring mechanism to deliver instant engagement and consistent performance over time.

How Do Reell Clutches Improve Performance?

Consistent, Predictable Torque Output

Reell’s precision-controlled wrap spring manufacturing ensures tight timing tolerance and repeatable engagement. This eliminates variability common in standard clutch designs.

Engineering Impact:

  • Reliable system performance without compensation

  • Reduced tuning and calibration

  • Consistent performance across production variability

Fast Engagement and Release for Precise Timing

Reell Clutches transition between engaged and disengaged in milliseconds, enabling accurate control of shaft motion in timing-critical systems.

Engineering Impact:

  • Improved indexing and registration accuracy

  • Reduced misfeeds in paper handling systems

  • Clean start/stop behaviour without lag or overshoot

High Torque Density in Space-Constrained Designs

Reell wrap spring clutches deliver high torque in a compact form factor, supporting applications up to 75 lb-in (8.5N-m) across 1 million cycles while minimizing system size.

Engineering Impact:

  • Enables smaller assemblies

  • Reduces need for additional gearing or oversized motors

  • Simplifies mounting and system design

Slip-Free Engagement with Minimal Backlash

Reell’s precision wrap spring design and manufacturing create a positive mechanical lock when engaged, eliminating slip under the rated load and minimizing any backlash.

Engineering Impact:

  • Maintains positional accuracy

  • Improves repeatability in precision systems

  • Eliminates drift associated with friction-based clutches

Engineered for High-Cycle, Long-Life Performance

Reell clutches are optimized for intermittent motion applications with frequent cycling, maintaining consistent torque and engagement behaviour over time.

Engineering Impact:

  • Reduced maintenance and downtime

  • Stable performance over product life

  • Lower total cost of ownership

Slip Device Clutches

Reell slip devices provide an in-line constant torque, which increases the life of clutch components by reducing the engagement shock due to inertia. They complement clutch systems where both precision engagement and torque limiting are required.

They can also be used for overload protection where component safety is a concern. They offer long life and consistent, repeatable performance in a small package.
