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.
Test your knowledge of gears with this quiz on the basics of different gear types, including spur gears, idler gears, bevel gears, and worm gears. Learn about how gears change speed, torque, and direction of rotating axles as you build your understanding of these essential mechanical components.
