Blow Molding; Process, Types, Materials…
Bevel gears are one of the most important mechanical elements in machinery. In the design phase of power transmission, there are lots of bevel gear mechanisms are used. In here you will find the information about;
Bevel gears are used for the power transmission between non-parallel shafts. In general, shafts are in a 90-degree position. Cone-shaped bevel gears are produced for the power transmission between these shafts.
Bevel gears can be also used for only changing the rotation direction of power transmission which are called miter gears. For miter gears, input and output bevel gears have the same number of teeth.
There are four types of bevel gears are available in general mechanical design; Hypoid type, spiral type, zero spiral types, and straight type bevel gears. In general, when the concept of ‘bevel gear’ is spoken, people generally think of the straight type of bevel gears. But the situation is not like that.
The most general type of bevel gears is the hypoid type bevel gear. Other types of bevel gears are designed from hypoid type bevel gears in terms of several parameters.
In the hypoid type of bevel gears, all the geometrical features are available. The offset position of the pinion provides power transmission between perpendicular shafts that are not placed in planar position. Other types of bevel gears must transmit power between planarly aligned shafts.
Spiral angles are generally between 20-45 degrees. But most generally used bevel gear spirals 35 degrees. The pressure angle of general spiral bevel gears is 20 degrees. Also, the minimum number of teeth is generally 12.
As you see above, there are lots of geometric variables available for calculation. You just need to enter the diameters of mating bevel gears and the number of teeth of these bevel gears. Diameters must be entered in inches because the diametral pitch is used in calculations.
After entering the required values inside brackets, click on the ‘Calculate!’ button to see all geometric results related to your bevel gear mates. If you want to do another calculation, just click on the ‘Reset’ button, then re-enter new values.
Take a look at the article about the difference between diametral pitch value and metric module value for gears.
As you see in the above calculator, the geometries of bevel gears are a bit complex compared with other gear types.
