Study Notes
Gear Functions
- The idler gear is used to change the direction of rotation without changing the gear ratio.
Gear Types
- The most common type of gear is the spur gear.
Gear Ratio
- A gear ratio of 5 to 1 means that the output shaft rotates at 1/5 the speed of the input shaft, while the torque is multiplied by 5.
Gear Mounting
- Bushings are placed on the back side of a 1x16 beam when using a gear to provide a clearance fit for the gear's shaft, reducing friction and allowing for smoother rotation.
Worm Gear
- The worm gear is a type of gear that allows for high gear ratios in a small package, and is often used in applications where a high torque is required in a confined space.
