Double Clutches

Excel Electromagnetics offers Double Clutch, EDCC. This consists of two EFMC series clutches in a single housing and a single tandem shaft. EDCCs are manufactured considering the higher frequency of forwarding and reversing mechanics. A combination of clutches is used for reversing revolution of the driven member with driving member turning in one direction. Also a combination of clutches is used to increase or decrease the speed during operation without stopping the driving member. Load is being transferred either by the first or second clutch. At a time only one clutch gets engaged while other remains idle. Safety factor (K): to ensure necessary transmission safety also under extreme operating conditions adequate safety factor must be considered the value of which depends on operating conditions namely, the type of load, prime mover, etc. Typically for electric drive: low masses equal loading and non-intermittent operation - 2.0; low masses light shock load and intermittent operation - 2.5; medium masses, light shock load and intermittent operation - 3.0; large masses, light shock load and intermittent operation - 3.0; non-overhauling loads - 2-3; overhauling loads - 3-4; diesel engine drive - 4-5; and compressor driven - 5-6.
