Which of the following is NOT an advantage of helical gears?
A) quiet performance
B) more than one tooth is in mesh at the same time
C) reduce thrust forces
D) high strength
Helical Gears
Gears featuring teeth that are cut at an angle to the face of the gear, allowing for smoother and quieter operation compared to straight-cut gears.
Thrust Forces
Thrust forces are axial forces that act along the length of a structural element or mechanical component, pushing or pulling in a direction parallel to its axis.
- Understand the maintenance and mechanical considerations in transmission operation, including backlash and gear mesh.

Final Answer :
C
Explanation :
Helical gears do not reduce thrust forces; instead, they generate axial thrust. This is a disadvantage compared to spur gears, which do not produce significant axial forces.
