In Spur Gear The Shaft Is __________ To The Gear?
- Parallel
- Horizontal
- Perpendicular
- None above
Explanation
In a spur gear system, the shaft is parallel to the gear.
Spur gears are specifically designed for applications where power is transmitted between parallel and coplanar shafts.
Teeth orientation:
-Spur gears have straight teeth that are cut parallel to the gear's rotational axis.
Shaft alignment:
-Because of this tooth orientation, spur gears can only mesh correctly if they are fitted to shafts that are also parallel to each other.
Contrasting gears:
Other gear types are used for different shaft arrangements:
-Bevel gears are used when shafts intersect.
-Worm gears are used for non-intersecting and non-parallel shafts.
