Question:
Spur gears have:
Spur gears have:
Show Hint
Spur gears are the simplest type of gear, with straight teeth aligned parallel to the axis of rotation, making them easy to manufacture and widely used.

- Helical teeth
- Straight teeth
- Bevel teeth
- Spiral teeth
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Spur gears are a type of gear with straight teeth that are parallel to the axis of rotation. They are the most commonly used type of gears for power transmission in machinery.
- Helical teeth are found in helical gears, which have teeth that are angled relative to the axis of rotation.
- Straight teeth are characteristic of spur gears. These gears operate with teeth that are aligned in a straight line along the gear's axis.
- Bevel teeth are found in bevel gears, which are used to transmit motion between intersecting shafts.
- Spiral teeth are a characteristic of spiral bevel gears, which are similar to bevel gears but with curved teeth.
Thus, spur gears have straight teeth.
