Performance Characteristics The Model CBH combination clutch-brakes are oil immersed units with a spring-set brake and hydraulically-set clutch. They are designed for extremely high cyclic rates and for those applications that require a high degree of stopping accuracy. Hydraulic actuation and precise control of piston stroke contributes to an extremely fast response time. Actuation volumes are very small and the fluid's virtually incompressible characteristics means that piston motion times can be as low as 5-10 milliseconds. This, in turn, allows for more shaft motion time since the units' hydraulic response time is so short. Cyclic rates in excess of 300 cpm are not uncommon in some applications. Such high cyclic rates induce a large amount of shock into the mechanical components of the unit and all members are designed to withstand these loads. Oil films help dampen these shock loads and the units run extremely quiet. Noise reductions of 25-30 dBA are common when compared to dry units running at the same speeds and loads. Wear characteristics of the Model CBH units are excellent. As an example, a Model CBH unit was endurance tested for 120 million cycles with no appreciable lining or mechanical wear. A dry unit was tested at the same load level and found to require re-line every 10 million cycles and complete unit replacement every 30 million cycles. There are many industrial applications which require longevities of this magnitude and the Model CBH has exhibited outstanding performance in these instances. Advantages Combination clutch-brake eliminates the possibility of clutch-brake fight Hydraulic actuation for fastest possible response time Impervious to adverse operating environments Wear virtually non-existent Capable of high cyclic rates Extreme stopping accuracy Quiet operation The following datasheet (PDF file) will provide product specifications and information for the Oil Immersed combination clutch-brakes.
