Wichita Has PTOs For Large Diesel Engines- Literature Available
Power take-offs (PTOs) designed for use on diesel engines with indirect drives are now available from the W i c h i t a Clutch Company, a subsidiary of Dana Corporation. These PTOs can handle the horsepower range from 250 to 800 hp at speeds up to 2,100 rpm.
Wichita's PTOs utilize the Wichita airtube disc clutch for smooth power transmission. The airtube disc clutch consists of a series of alternating discs connecting an inner drive member to an outer drive member. Engagement is achieved by pneumatic expansion of the airtube. The air clutch provides controlled slip actuation for smooth start-ups. Torque is delivered in direct proportion to air pressure applied, providing easy and accurate control of torque build-up. The air clutch eliminates problems normally associated with mechanical clutches, such as lever and linkage wear.
These PTOs are ideal for use with V-belts or other drives. They isolate the side load from the crankshaft flange of the engine so that all of the side pull is carried by the PTO bearings and the housing. Wichita PTOs are also ideal for automated control systems. Remote control of the clutch as well as the engine throttle is easily accomplished through a simple air system.
