Skip to content One of my main reasons for buying a PCNC CNC milling machine from Tormach was to have the potential to create clock components on the mill without the sweat of cutting teeth through indexing on the lathe and crossing out by hand filing. Full control of all design parameters like spokes and hub diameter means you can easily generate beautiful custom clock-type wheels too! Show cm grid Show a 1 cm grid. You can now buy a downloadble gear template generator.

Involute Spur Gear Builder
However, for wooden gears, it really doesn't matter very much. The next printout should be the correct size. You can now zoom in and out of the preview with the mouse wheel and drag the picture around to suit your specific needs. The checkbox controls whether one or two gears are rendered. Even if you don't cut the gears with an involute shape, the template generator is still useful as a form of protractor using the "dividing plate mode" for dividing the circle into even intervals.
Free Gear Design Software
There is also a bottom clearance but it is not considered in simple calculations. This function hides the text at the bottom of this page and tells your browser to start the "print dialog" to print this page.
Simply enter a negative number of teeth for one of the gears, and that gear will be an inside gear.

Number of teeth on gear to render for gear. This software is 2. It's saving me so much time.
Lightly scribed alignment lines mark the plate's center. Example plywood gears from a template. The angle of this line with respect to vertical is the pressure angle 'Tooth angle' field in the form above The gear tooth generation is not perfect.
The red line will show the line of tooth contact for the given gears, as well as the base circles. After printing a test page, measure the distance between the lines marked "this should be mm". Epicycloid, the shape above the base circle. After degreasing, the brass plate is mounted using double-sided tape. For gears larger than a sheet of paper, the gear is offset from center.
You can email me at More projects with wooden gears: Physical samples of gears printed on 3D printer. Depth of the tooth below the pitch circle diameter. Modified the supplied packaging to safely hold the cutter desginer. Subsequent printouts should be scaled so that the millimeters are exact and the grid has 1 cm spacing. Adding 2 to the teeth number works because gears contact each other at exactly one-half the distance from the top of the gear to the bottom.
The path is depicted by a virtual marker at the end of a taut string as it unwinds off a cylinder the gear's base circle.
This free online gear template generator is designed for making scale accurate paper gear templates which you can glue onto wood and then cut out with a bandsaw. Mounting the 4-jaw chuck. The ratio between the two circles is used to derive the pressure angle.
Show line of contact Shows the pressure angle, and the base radius. This application is an aid to the design of simple spur gears using either involute or cycloidal tooth form. Not for a clock but another example of Mach3 controlled CNC produced gears. Point at which the pitch circle diameters of two gears in mesh coincide.
Handles BOTH internal and external spur gear designs as well as clock-type gears.
