What can i do with a mechanical engineering degree: Comparing efficiencies of unlike gear types across diverse reduction ratios volition aid us to brand correct gearbox alternative for our applications. Please banking concern annotation that these efficiency values are for full general guideline as well as refer manufacturers catalogue for to a greater extent than accurate values.
Gear Efficiency Comparison Table
| No | Type | Normal Ratio Range | Efficiency Range |
| 1 | Spur | 1:1 to 6:1 | 94-98% |
| 2 | Straight Bevel | 3:2 to 5:1 | 93-97% |
| 3 | Spiral Bevel | 3:2 to 4:1 | 95-99% |
| 4 | Worm | 5:1 to 75:1 | 50-90% |
| 5 | Hypoid | 10:1 to 200:1 | 80-95% |
| 6 | Helical | 3:2 to 10:1 | 94-98% |
| 7 | Cycloid | 10:1 to 100:1 | 75% to 85% |
1. Spur Gear Efficiency
What can i do with a mechanical engineering degree: Spur gearing is a parallel shaft arrangement, as well as these gears tin accomplish much higher efficiencies compared to other gear types. Its efficiency varies from 94% to 98% amongst lower gear ratios.
2. Straight Bevel Gear Efficiency
What can i do with a mechanical engineering degree: Straight bevel gearing is like to spur gearing amongst perpendicular shaft arrangement. Like spur gearing these gears also alone tin grip lower gear ratios amongst higher efficiencies (93% to 97%).
3. Spiral Bevel Gear Efficiency
What can i do with a mechanical engineering degree: Because of molar cast as well as contact spiral bevel having less dissonance as well as racket compared to lead bevel gears, as well as hence having improve efficiency (95% to 99%).
4. Worm Gear Efficiency
What can i do with a mechanical engineering degree: Worm gear efficiency varies significantly when Pb angle, friction component subdivision as well as gear ratio changes.
Worm Gear Efficiency Calculation
What can i do with a mechanical engineering degree: Use the next gear efficiency equation to calculate efficiency of worm gears.
What can i do with a mechanical engineering degree: 
5.Hypoid Gear Efficiency
What can i do with a mechanical engineering degree: 
What can i do with a mechanical engineering degree: The efficiency of a hypoid gear is roughly 80-95% as well as tin accomplish really high gear ratios upward to 200:1.
What can i do with a mechanical engineering degree:
6. Helical Gear Efficiency
What can i do with a mechanical engineering degree: Helical gears tin run amongst really high pitch draw of piece of occupation velocity as well as tin accomplish much higher efficiencies (94%-98%) amongst maximum gear ratios upward to 10:1.
7.Cycloid Gear Efficiency
What can i do with a mechanical engineering degree: These gears tin operate inwards really high efficiencies at relatively high gear ratios higher upward 30:1 as well as nether normal working weather condition cycloid gearing efficiency ranges from 75% to 85%.
