Fusee With Cord.png


Description

The Fusee was invented to compensate for the reducing turning power (or Torque) of a clockwork spring as it winds down.


Features and Applications

The Fusee is essentially a conical pulley and the drive is transferred progressively from a large diameter Driver to a smaller diameter Driver with a consequent increase in Mechanical Advantage.


Cone shaped pulleys are sometimes also used in Potters' Wheels to create a variable speed drive.


Animations
Variable Cone Drive - the input and output shafts are parallel and the output velocity is varied by moving the drive belt.
Variable Cone and Disc Drive - the drive is transmitted from the top disc to the one below via a double cone roller which can be positioned to vary the output velocity.
