Oil Cooled Multiple Disc Clutches and Brakes - Airflex CH heavy duty multiple-disc units - Airflex - #1

Element Description

Type CH

Type CH elements are designed specifically for heavy duty clutch and brake applications. They can be air or hydraulically actuated. The friction disc packs are suitable for either wet or dry operation. Actuation is accom­plished through internal shaft and clutch passages, similar to the Type AR. When used as a wet clutch, coolant oil is forced through the friction disc pack from an internal shaft passage.

The element hub is bored and keyseated for shaft mounting. Torque is transferred from the disc pack to a splined drive ring.

Type CH elements are available in six sizes with torque ratings to 1,038,000 lbin (117.200 Nm).

Other design features include:

• Qualified for American Bureau of Shipping (ABS) Type Approval.

• Long-wearing, self-lubricating PolyPak* seals eliminate premature twisting failure and requires no external lubrica­tion.

• Nituff^] coating, a Teflon* impregnated hard coat anodizing, is used on the cylinder walls to create a self-lubricating surface to minimize wear and reduce corrosion.

• All splines processed with Ionitriding* to retard wear and increase corrosion resistance.

• Sintered bronze friction material, operating in oil, provides a low static-to-dynamic torque ratio for smooth long-lasting, high en­ergy performance.

• Mechanical lock-up screws.
