Question 1.
What is the pitch circle?
Show hintHide hint
Think about where the teeth contact each other.
Question 2.
Define the term 'addendum'.
Show hintHide hint
It's all about the height of the tooth.
3Question 3.
What is the module of a gear?
- Ratio of pitch diameter to number of teeth
- Distance from pitch circle to top of tooth
- Angle between tooth profile and line of action
Show hintHide hint
It's about tooth size!
4Question 4.
True or False: Backlash is essential for smooth operation in gear systems.
- True
- False
Show hintHide hint
Consider what happens without space between parts.
Question 5.
Design a gear pair that operates smoothly with a pitch circle of 100 mm and a desired module of 5. What would be the number of teeth on the gears if one gear needs to have 10 teeth?
Show hintHide hint
Apply the formula for module effectively.
Question 6.
If the pressure angle of a gear is increased from 14.5° to 20°, how does it affect the manufacturing complexity and tooth engagement?
Show hintHide hint
Think about both manufacturing and performance effects.
