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
- Examples from Nguyen Duc Thang's YouTube Channel 2100 Animated Mechanical Mechanisms
| 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. |
