You asked: How to draw involute gear tooth profile in autocad?

Draw a radial line from base circle on the right hand side to the pitch circle and another from the pitch circle to the new circle (the outside). Make these two lines equal length, so the outside circle is the same radial length larger than the pitch circle as the base circle is smaller.

Also, how do you draw involute gear in CAD? When drawing an involute, you draw one side of one tooth, mirror that to make a whole tooth, and that copy that around your gear the right number of times. A new involute has to be drawn for each size of gear in your system. To begin drawing, lay out three concentric circles: One at the pitch circle.

What is involute profile?

The most common type of gear tooth profile is the involute gear tooth profile, standard and corrected. An involute gear profile means that the profiles of the gear teeth are involutes of a circle, while the involute of a circle is the locus of a point on a piece of string as the string is unwrapped from a circle.

What is module in gear?

What is the module of a gear ? In general, the size of a gear tooth is expressed as its module. The sizes of gear teeth using the module system are indicated with the symbol m followed by numerals such as m1, m2, and m4 where the teeth sizes get larger as the numerical value increases.
