Bevel gears are essentially conically shaped and are commonly used to transmit power between shafts that intersect at a 90-degree angle and are also used to change the direction of a shafts rotation. Therefore, bevel gears are popular in situations that demand a right-angle gear drive.
Helical gears contain teeth that are placed at an angle to the shaft, causing several teeth to be in contact during operation, and helical gears are capable of carrying a heavy load. This configuration also allows helical gears to run smoother and quieter due to load sharing between teeth. Thus, helical gears are able to generate thrust during operation, which should be taken into account when used.
2. What are the applications of Bevel Gears?The most popular application of bevel gears is in the automotive industry, in automotive vehicles, automobiles and also in light and heavy equipment. Besides that, bevel gears are also used in everyday items such as printing presses, power plants, cooling towers, steel plants, railway track inspection machines and the aviation and marine industry.
3. What are the advantages of using Bevel Gears?One of the biggest advantages of bevel gear is the ability to change the operating angle. Besides that, the mechanical advantage can be altered by varying the number of teeth (effectively diameter) on each wheel. The ratio of rotations between the drive and driven wheels can be changed by increasing or decreasing the tooth ratio between them, which means the rotational drive and torque of the second wheel can be changed in relation to the first, with speed increasing and torque decreasing, or speed decreasing and torque increasing.
