Gears Flashcards
(7 cards)
1
Q
What pros do gears have over belts?
A
- Higher transmission efficiency due to less friction
- Takes up less space
- No slippage
- Suitable for short-distance transmission
2
Q
Name the key features of helical gears
A
- Angled-teeth for smoother and quieter operation
- Suited to high-speed applications
- High efficiency
3
Q
Name the key features of spur gears
A
- Simple design with straight teeth parallel to shaft axis
- Constant velocity ratio
- Suited for low-speed applications
4
Q
Name three features of a rack and pinion gear
A
- Comprises of a circular gear (pinion) and a linear gear (rack)
- Converts rotational motion to linear motion
- Used in steering systems
5
Q
Name three key features of a straight bevel gear
A
- Cone-shaped toothed wheels
- Transmits power at intersecting shafts (usually at 90° )
- Used in differential systems
6
Q
Name the key features of an internal gear
A
- Compact design with inside teeth meshing with external gears
- High transmission efficiency
- Used in planetary gears and for high-speed reduction
7
Q
Name the key features of a screw gear
A
- Angled teeth like helical gear
- Transmits power between non-parallel and non-intersecting shafts
- Compact with low load-bearing capacity
