DRAWN CUP ROLLER CLUTCHES FOR USE IN PLASTIC HOUSINGS

EWC FCP AND DF TYPES

Types FCP and DF clutches feature axial grooves in the outside surface of the clutch cup. It is important that these grooves align with similar protrusions in the housing bore to prevent the clutch from slipping relative to the housing.

Types FCP and DF clutches are available with bore diameters of 4, 6, 8 and 10 mm.

These clutches may be made available already mounted in a plastic housing such as a gear or a pulley to meet the customer’s design specifi cations.

CHARACTERISTICS

• Easily unitized – they can be unitized with plastic parts such as gears, pulleys, rollers, etc. as needed.

• Creep preventing structure – creep is prevented by mating a thin cross section roller clutch, which has special grooves on O.D. formed by a precision press, with a plastic part that has an equal number of bosses on the bore of the housing.

• High precision and good durability – high precision and good durability is obtained because cam surfaces are formed by precision deep drawing.

• Small and compact – this series satisfi es the need for a lighter compact product.

STRUCTURE

Drawn cup roller clutches for plastic housings are composed of a drawn cup with internal cam surfaces and creep preventing grooves on O.D., rollers, and a retainer with either integral plastic or stainless steel springs.

The plastic housings can be a plastic gear, a pulley, a roller, etc., so it is possible to design the housing to meet any customers’ needs.
