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. I recommend printing the gears with an ink jet printer. Even cheap ink jet printers print very scale accurate but Not all laser printers are accurate. You can still access the old (pre 2015) Legend (What do the fields above mean?) Tooth spacing Number of millimeters from one tooth to the next, along the pitch diameter.

Gear 1 teeth: Number of teeth on gear to render for gear. Controls left gear when showing two gears. Enter negative value for ring gears. Rack&Pinion: Change gear 1 to a linear gear (rack). You can also make the other gear a rack by entering '0' for the tooth count.

Gearotic is a 3D gear template generator to design clock escapements, tabbed boxing, circular and non circular gears, and even Celtic Knots. All the gears are created using proper mathmatical models of the tooth forms involved.

Measured cal distance (mm): After printing a test page, measure the distance between the lines marked 'this should be 150 mm'. If it's not 150 mm, enter the value in this field to compensate for printer scaling. The next printout should be the correct size. Contact angle(deg): The pressure angle of the gears. For gears with smaller number of teeth, set this a bit larger, to get more sloped teeth that are less likely to jam.

Gear 2 teeth: Number of teeth for the gear on the right, if rendered. The checkbox controls whether one or two gears are rendered. Two gears: When printing templates, it helps to have just one gear shown. Spokes: Show the gear with spokes. Spokes are only shown for gears with 16 or more teeth. Shaft hole dia.

(mm): What size to draw the shaft hole. For inside (planetary) gearing, set this larger than the gear to draw a circle around the gear Show rotated: Rotate the gears shown slightly.

Useful for checking the fit of gears at different angles when showing two gears on the screen. Use values 0 to 100 to indicate percentage of one tooth advance of rotation. Print gears: This function hides the text at the bottom of this page and tells your browser to start the 'print dialog' to print this page. Show pitch diameter Show the pitch diameter of the gears. The pitch diameter is the effective diameter of the gear. Show line of contact Shows the pressure angle, and the base radius.

Show cm grid Show a 1 cm grid. Use the 'printed page width' to scale exactly to your printer Animate Turn the gears on the screen. Good for checking meshing of gears with small numbers of teeth. Dividing plate mode Sometimes you just want to divide a circle into something like 17 equal parts, and the gear template is handy for that. Checking this option just draws the dividing lines and no gear teeth. Getting the printout to scale correctly, avoiding cropping Different browsers print at different scales depending on browser type and printer configuration. The default scale should be correct for firefox, Internet explorer 10 and Google Chrome.

If the scale is not correct (that is, the grid is not 1 cm increments), measure the distance that is labeled 'If this is not 150 mm.' In millimeters and enter it in the field 'Measured cal distance'. Billy joel piano man legacy edition torrent. Use an ink jet printer I recommend using an ink jet printer.

The colour registration requirements of ink jet print heads requires manufacturers to make sure the image is not stretched in either direction, so even cheap ones are quite scale accurate. Some laser printers stretch or distort. Printing the gear templates To print the gear template, use the 'Print' button, instead of printing the web page from the browser. The print button hides those parts of this page that you don't want to print, then brings up the print window. To get the sizes specified to be correct, it's best to print a test template, and then measure the distance between the lines at the bottom of the image, and enter that under 'Measured cal distance'. Only enter this once (the value will reset).

Subsequent printouts should be scaled so that the millimeters are exact and the grid has 1 cm spacing. This program only prints what fits on the screen. To fit more, you can zoom out in your browser on a PC by holding down the 'Ctrl' key and puhing the '-' key. For gears larger than a sheet of paper, the gear is offset from center.

If your gear has an even number of teeth, you can print it twice and paste the halves together. If the number of teeth is divisible by 4, you can print it 4 times and paste together. You can print gears up to 40 cm (16') in diameter this way. The that I created and sell doesn't need the scale calibration, and can paginate across many pages for larger gears. Some notes about gear design and this gear template generator This template generator is intended for generating paper templates for cutting low precision gears from plywood, phenolic, or other suitable materials with a band saw. This gear template generator generates shapes for involute spur gears. Involute spur gears have involute shaped teeth.
