6.5. Rack and Pinion

Try these first

1. 1.

   What does a pinion do in a rack and pinion system?

   Hint

   Think about the role of gears in motion.

2. 2.

   Name a common application of rack and pinion systems.

   Hint

   Where do you turn the wheel on a car?

3. 3.

   What is the primary function of a rack and pinion system?

   • Convert linear motion to rotary motion
   • Convert rotary motion to linear motion
   • Store energy

   Hint

   Consider the motion direction: rotating vs. moving straight.

4. 4.

   True or False: A rack is a circular component in the rack and pinion system.

   • True
   • False

   Hint

   Visualize the shape of both components.

5. 5.

   Design a minimalistic prototype for a rack and pinion mechanism to lift a small weight, detailing materials, dimensions, and calculations for torque required.

   Hint

   Think about how much force is needed to lift the weight and how the gear’s size affects this.

6. 6.

   Assess the limitations and potential failure modes for a rack and pinion system in an automated conveyor belt application.

   Hint

   Consider what happens with continuous use of mechanical parts over time.
