Study Notes
Geneva Wheel Overview
- Also known as a Geneva Drive, a mechanism used to convert continuous rotation into intermittent rotation.
Common Applications
- Frequently employed in film projectors, elevators, watch movements, and slot machines for precise, controlled movements.
Oil Encasing Purpose
- Encasing the Geneva wheel in oil serves to reduce friction and wear, enhancing durability and operational smoothness.
Drive Wheel Rotation Impact
- For every 360-degree rotation of the drive wheel, the Geneva wheel advances by a set increment, typically one full stop or a specific angle.
Historical Use in Image Projection
- In early image projection systems, Geneva wheels facilitated frame advancement, allowing images to be displayed sequentially for storytelling purposes.
