Component Specifications

Definition
The Control Ring is a critical rotational component within a Coupling Iris assembly, designed to precisely adjust the iris aperture through controlled angular displacement. It functions as the primary interface between the actuator mechanism and the iris blades, converting rotational input into linear blade movement to regulate flow, light, or material passage in industrial applications.
Working Principle
The Control Ring operates on a cam-follower principle, where its inner circumferential groove or track engages with pins on iris blades. Rotational force applied to the ring causes the groove profile to translate blade pins radially, synchronously opening or closing the iris aperture. This provides precise, repeatable control over the opening size with minimal backlash.
Materials
Typically manufactured from hardened alloy steel (e.g., AISI 4140, 17-4PH stainless steel) or aluminum alloys (6061-T6) for lightweight applications. Surface treatments include black oxide coating, nickel plating, or PTFE impregnation for wear resistance and smooth operation.
