Pininon gear is a small cogwheel. The teeth fit into a larger gear
wheel. Rotational motion is converted into linear motion when the pinion
turns and moves the rack. Pinion gears are engineered to be the best
gears and hence very popular in various industrial applications. How does a Pinion Gear Operates?
Pinion gear system involves the use of a small round gear called pinion and a large flat gear called rack, more the number of teeth in the pinion gear, more is the speed of rotation. Pinion with smaller number of teeth produces more torque. Pinion is attached to the motor shaft with glue. Rotation of pinion is done by rotation of pinion about a fixed center that helps the rack to move in the straight line. If the rack is moved and the pinion rotates then the center of the pinion moves taking along the pinion with it.
Materials of Construction
The gears are constructed from materials like
- Cast iron
- Steel
- Aluminum
- Bronze
- Carbon steel
- Hardened steel
