- Select Insert / Boss/Base / Extrude… to create a cylindrical gear blank.
How do you draw an involute gear tooth profile?
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.
How is an involute profile designed?
In an involute gear, the profiles of the teeth are involutes of a circle. The involute of a circle is the spiraling curve traced by the end of an imaginary taut string unwinding itself from that stationary circle called the base circle, or (equivalently) a triangle wave projected on the circumference of a circle.
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.
How do you modify gears in SOLIDWORKS?
Navigate and Right click “Spur Gear” from the listed options and left click “Create Part.” The part should appear in the main editing window. 4. Change the options in the left hand column (titled “Configure Component”) to create the desired gear.
Why involute profile is used in gears?
An involute gear has the profiles of its teeth in the shape of an involute of a circle. This structure helps to reduce torque variation and allow greater assembly flexibility, helping to make involute gears one of the most popular power transmission devices.
What is gear tooth profile?
Gear Tooth Profile: One of the fundamental s of gear design is the profile of the gear tooth. Gears generally have an involute curve tooth profile. There are other types of gear profiles, but they are mainly utilized in specialty applications such as cycloidal gears in clocks and watches.
What is gear involute profile?
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.

How to create accurate involute gears in SolidWorks?
This post will help you create accurate involute gears in SolidWorks. To accurately generate involute curves in SolidWorks we will be using Equation Driven Curves in our sketches. That means we will be needing some equations, and there are quite a few for involute gears:
How to make an involute gear?
Join the lower end of the spline with the center of the circle with a line.. create a construction line in the point shown in the picture.. mirror… convent entities for the 2 circles.. trim… extrude the circle… then the tooth.. add fillet linked with the following equation… And Voila…. a fully defined involute gear…

How to calculate the number of teeth on a gear wheel?
2) The module, m, expresses the size of the teeth and thus also the total number of teeth and the overall size of the gear wheel. I chose m=2. Therefore the number of teeth, N, is N=P/m=76/2=38.
