A cost-effective indexing clutch solution was needed at a major food processing OEM for use on a new cookie filling machine. The conveyor head shaft has the indexing clutch mounted on it. Which, interprets the reciprocating motion from the crank mechanism into incremental motion in one direction. Advancing the conveyor a uniform distance with each drive stroke and then on the return stroke overrunning in the opposite direction.
HPI indexing clutches from Formsprag were chosen over competitive units to meet the challenge of this washdown application. HPI ball bearing clutches are specially designed for medium to heavy-duty indexing applications in excess of 150 strokes/min. or greater than 90 degrees of index, to provide superior dependability, uniformity, and long-life performance.
Model HPI 550 clutches were supplied with a torque capacity of 1,885 lb.ft. (2598 Nm). The clutches feature lip-type seals and were shipped with FDA-approved, food-grade grease. The units also featured an anodized coating developed to withstand the rigors of caustic washdown environments.
