www.thomsonlinear.com 1 Clutches & Brakes Building Our Business On a Strong Foundation Thomson has a long history of manufacturing quality clutches and brakes. Our roots are firmly planted in brand names such as Deltran, API (American Precision Industries), and Warner PSI bringing over 100 years of combined manufacturing experience. Deltran joined Danaher Motion in March 2000, followed in July 2000 by the acquisition of Warner PSI. The Genuine Wrap Spring and electromagnetic friction products were later combined under the Deltran name within the Thomson family. As we merged the manufacturing of...

6 www.thomsonlinear.com Input Output Control Tang Wrap Spring Design Configurations Overrunning Clutch In its basic form, the wrap spring clutch operates as an overrunning clutch. When the input hub is rotated as shown, the spring wraps down to engage the two hubs. If the input is stopped or reversed, the spring unwraps to release the output hub, allowing the load to overrun. PSI Series overrunning clutches can also perform one-way indexing and backstopping functions. Start-Stop Clutch (Random Positioning) Modifying the basic PSI Series clutch with a control tang allows the clutch to engage and...

www.thomsonlinear.com 7 THE GENUINE WRAP SPRING Clutches & Brakes The Genuine Wrap Spring clutch/brakes provide hundreds of simple motion processes that can be controlled through the three basic wrap spring clutch functions: overrunning, start-stop, and single revolution. Important Facts • The torque capacity of a spring clutch or brake is a direct function of the diameter of the hub and the tensile strength of the spring. • A spring clutch or brake will not slip. It will attempt to supply the torque demanded, up to the mechanical limitations of the spring. • When the spring is allowed to wrap...

THE GENUINE WRAP SPRING www.thomsonlinear.com 9 Clutches & Brakes Linear-to-Rotary Translation Rack and Pinion Indexing Drive Since wrap spring clutches are inherently uni-directional, the PSI/ACCM overrunning model “O” clutch in this application operates as a ratchet drive. When the rack is moved upward, the wrap spring clutch engages to translate torque to the feed conveyor. On the downward side of the stroke, the wrap spring clutch is disengaged. Advantages • Simple—requires no external controls or sensors • Reliable • Maintenance free Product Selection • PSI • ACCM Precise Registration Print...
