LOADLESS STARTING CENTRIFUGAL AUTOMATIC CLUTCHES

 

- WHY USING A CENTRIFUGAL AUTOMATIC CLUTCH

- FEATURES

- TYPES  
  -"A" SERIES CLUTCH PULLEY
  - "A" SERIES for pulley (From A-0 to A-2)
  - "A" SERIES for pulley (from A-3 to A-8)
  - "B" SERIES to join two aligned shafts
  - "C" SERIES to join driving wheel with load shaft
  - "D" SERIES, to be set between aligned shafts (From D-0 to D-2)
  - "D" SERIES, to be set between aligned shafts (From D-3 to D-8)
  - "E" SERIES, to be set on the load shaft

- NOTE

 

Features :

  • Loadless starting.
  • Avoid failures due to overloads or clogging.
  • Allow less powerful engines to be used.
  • Electrical accessories are no longer needed.
  • For explosion engines, they can be automatically disconnected when idling.
  • Acceleration time can be adjusted by adding or removing centrifugal mass, depending on if we want either to shorten or to lengthen that time.

How it works:

When idling, the driving part remains completely free and independent from the driven part, since the centrifugal masses are hold on the plate by an spring; as there is no rotation there is not impulsory or centrifugal force to produce the massess to expand.

When the engine begins to run, the masses, because of the centrifugal force, are expanded with a force directly proportional to the square of the speed. The masses reach the sleeve to which a friction force is forwarded and then the rotation movement is transmitted.

Note :
  - Our units are delivered without drilling nor notching, but both of them can be done, by adding their additional cost, in case they are required by the customer.
 

- Powers shown in the tables can have 20% overloads. For harder applications ask our technical department.
  - If clutches are used as torque limiters and must be exposed to long slipping periods, you should ask our technical department so that, after analysing the heat dissipation, they can choose the most suitable mechanism.
