Bevel Gears: Advantage

1. Operating angle could be changed and this characteristic of bevel gear makes it more flexible in operation
2. Bevel gears could also be made my nylon or plastic and such bevel gears made of plastics are generally used in electric toy industries.
3. 锥齿轮效率足够了;在少量情况下，锥齿轮可以提供高达90％的效率，并且在少数情况下也超过90％。
4. Manufacturing costing will be less
5. 斜面齿轮机构的滑动摩擦也将较低

Bevel Gears: Disadvantage

1. 锥齿轮应与相应的轴组装恰恰
2. Bevel gears are not desirable for high speed reduction; such gears could be used maximum speed reduction up to 5:1
3. 在高速时，这种传动机构会产生噪音

Worms and worms gear: Advantage

1. 可以确保更高的减速;减速可固定高达300：1
2. Worm and worm gears operate silently
3. Worm and worm gears will have one characteristics i.e. self locking. Reverse movement will be restricted but this characteristic depends on lead angle and friction angle, we have discussed this concept in our discussion in previous post during study of worm and worm gear.
4. 如果我们已经讨论过的空间，蜗杆和蜗杆齿轮单元将优选使用空间，因为我们已经讨论了蜗杆和蜗轮齿轮单元也可以用于紧凑空间的重速减速。
5. Handsome output torque will be secured here with the application of worm and worm gear.

Worms and worms gear: Disadvantage

1. 与锥齿轮的制造成本相比，制造成本浓厚
2. Cost of raw material to manufacture the worm and worm gear set will be quite high
3. Worm and worm gear set will have heavy power losses.
4. 效率将很低
5. If speed reduction ratio is large, worm teeth sliding action will create lots of heat
6. Lubrication scheduled must be strictly maintained for healthiness of worm and worm gear as this unit requires much lubrication for smooth working of gearbox.

Applications of bevel gears

1. 锥齿轮用于在速度和负载均小时在两个轴之间传输电源和运动。
2. Hypoid Bevel gears are used in various automobile applications such as vehicle differential drives
3. 锥齿轮大多是在海洋应用程序使用, locomotives, energy sector, steel sector, cement units, defence sector, cooling tower and printing presses.
4. 锥齿轮用作手钻的关键机制
5. Sewing machines use spiral bevel gears
