Hilliard single revolution clutches provide output cycles, on demand, from a continuously running input. The output cycles can be a fraction of a revolution, one revolution or multiple revolutions. This clutch typically provides five times the duty life of wrap spring clutches for indexing, shearing, bending, fastening, loading or similar applications. Each clutch is designed for a service life of up to 40 million cycles.
Other features include; positive engagement at any point of revolution without slip, lag or cumulative error, automatic disengagement at the same point of each operating cycle, no deterioration in performance throughout service life, ruggedly built and field proven, and controlled by a single trip lever which may be activated by a solenoid, an air cylinder or other mechanical devices.
