Explanation Of Pitch And Metric Module Of Spur Gears With Calculators
Because of the complex teeth geometries of spur gears, diameter calculations, teeth geometry calculations a bit complex. In here, we explain all the calculations related to the gear-teeth relations.
Designing of the construction of a machinery, all the geometrical features must be calculated. Contacting of pinion and gears must be calculated in detail to obtain required construction. There are bunch of terms related to these calculations;
You can use the calculator below to calculate Addendum, Dedendum and Clearance of a spur gear, if you know diametric pitch or metric module;
The use of calculator above to calculate addendum, dedendum and clearance values for spur gear mates is very easy. Select the required information from list which you know; diametral pitch or metric module. Do not forget that the unit of diametral pitch is inches and metric module is milimeters.
Enter the required value then click on ‘Calculate!’ button. To make an another calculation, click on ‘Reset’ button then re-enter the values.
Outside diameter of a spur gear is very important constructional value. It is generally referred as ‘Da’. If you know metric module or diametric pitch and number of teeth of your spur gear, you can use the calculator below to calculate outside diameter.
Just like calculator before this, you need to select the information you have baout your spur gear mates; metric module or diametral pitch…
Outside diameter calculated via diametral pitch formula is like below. Check your calculations with this formula;
Metric module outside diamater formula;
The diameter of a spur gear is calculated as extraction of two dedendum values from calculated outside diameter. This value is called as ‘D’.
Maybe center distance calculation is most important aspect of spur gear mates. Exact calculation of center distance is very important in terms of the construction of other elements inside machinery such as shafts etc.
If you know the number of teeths of pinion and gear mates, and diametral pitch or metric module, you can easily calculate the center distance value between mating gears.
Center distance formula via diametral pitch;
Center distance formula via metric module;
These calculators can be very useful when you are making spur gear construction design.
All the responsibility of calculations made in Mechanical Base calculators are about the users of calculators. Calculators are prepeared based on very reliable sources.
