“…Delrin is primarily used in automotive applications, seatbelt, control switches, loudspeaker grills, and windows. 29 Many industrial types of equipment are made of Delrin, gas meters, pumps and beverage valves, farm machinery, hose couplings, spur and helical gears, bevel and worm gears, and pump impellers. Most consumer goods and appliances are made of Delrin, including clips, toys, knife handles, rollers and chair coaters, zippers, a variety of pen components, garage door openers etc.…”

This paper discusses and analyses a compliant centrifugal clutch with different materials. Compliant centrifugal clutch specimens required for investigation are prepared by an injection moulding process. Experiments are conducted based on the experiments designed as per Taguchi’s Design of Experiment (DoE); an L27 Orthogonal Array (OA) is formulated and a multi-response optimisation approach Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) is adopted for optimising torque carrying capacity, wear rate and, contact temperature. Experiments are conducted for three different polymer materials viz., polypropylene (PP), Delrin (DE) and polyurethane (PU) with three different profiles, circular (CR), elliptical (EL) and square fillet (SF), along with varying rotating speeds. The outcome shows that by changing the clutch material and flexure profiles, a substantial variation in torque carrying capacity, wear rate and contact temperature is observed.
