If you want to create a high gear ratio, nothing beats theworm gear. In a worm gear, a threaded shaft engages the teeth on a gear. Each time the shaft spins one revolution, the gear moves one tooth forward. If the gear has 40 teeth, you have a 40:1 gear ratio in a very small package. Wormgearsare used when large gear reductions are needed.

Gear
Generator
- Gear Generator is a tool for creating involute spur gears and download them in DXF or SVG format. In addition it let you compose full gear layouts with connetcted gears to design multiple gears system with control of the input/output ratio and rotation speed. Gears can be animated with various speed to demonstrate working mechanism.
- Gear Ratio BJ-worm gears are available with the following nominal gear ratios: Dimensioning Gear Size and Gear Ratio By using the graphs on subsequent pages, you can dimension gear size, gear ratio and number of revolutions as well as motor according to your requirement. Alternatively, you can use the tables on pages 27 to 29.

Units
Gear Generator is unitless: if you wish it's inches, cm or millimeters. DXF opened in AutoCAD will have the same value for D/P as it is set above. Gears in SVG are measured in pixels, which is the value multiplied with the scale (Pixel per Unit) as it is displayed on the right side.

Why this tool was created? Just for fun. I'm working on a hobby project, a scale construction machine, which needed some spur gears, and I quickly made a simple spur gear creator script in Javascript with SVG output. As it was done, I couldn't stop, and I added more and more features, and finally I got this tool. It was a pleasure to code the whole thing, I'm a bit sad it is already done.
Support: [email protected]Notes about browser compatibility: all new major browsers are supported (i didn't tested IE), but unfortunately Chrome can't render SVG circle correctly. The winners are: Opera for the best performance (shame on me, I never use it) and Firefox for the best looking SVG render.
Update 1.5: Fixed DXF resolution issue. Maximum number of teeth increased to 400.
Update 1.4: TA-DA: Added internal gear support, and the ability of positioning the first gear.
Update 1.3: Fixed DXF file format.

What is a gear calculator?The gear calculator is a comprehensive software which, after inputting various parameters related to gear calculations, computes on-line automatically gear sizes, strengths, working forces, tooth forms, backlash conversions, etc. Because gear calculations require many complex formulas related to strengths and sizes, traditional gear design situations require highly specialized knowledge and suitable design time. By utilizing the gear calculator introduced here, it is possible to reduce these burdens substantially. Among the parameters requiring user input are the unit to specify gear tooth such as module or diametral pitch (DP) and its value, pressure angle, helix angle, number of teeth, coefficient of profile shift, center distance, material, rpm (rotational speed), face width, safety ratio, circumferential backlash, etc. This gear calculator software also handles gear calculations of various types of gears such as spur gears, worm gears, gear racks, bevel gears, internal gears, screw gears, etc.

What is a gear drawing software?The gear drawing software means an on-line automatic program to produce gear drawings when users input various parameters needed to define gear sizes. It also allows downloading the produced original (custom) gear drawings in the dxf format and expands them by using CAD software. Without this kind of dedicated gear drawing software, it would be necessary, after gear sizes have been determined, to use conventional CAD software and draw the gears from scratch. Therefore, the use of this kind of gear drawing software allows large scale improvement in gear designs.
Among the parameters requiring user input are the unit to specify gear tooth such as module or diametral pitch (DP) and its value, standard cross section of the tooth, coefficient of profile shift, precision grade such as JIS, hub diameter, bore diameter and its tolerance, size of the chamfer, various sizes related to keyway, number and positions of tapped and counterbore holes, etc. As with the gear calculator, this gear drawing software also handles making drawing of various types of gears such as spur gears, worm gears, gear racks, bevel gears, internal gears, screw gears, etc. Backlash conversion DISCLAIMERThis software is provided as an exclusive service to our registered users.The contents of the software may be revised for improvements without notice.Any damages directly or indirectly suffered by the users of this software are the responsibility of the users and we do not offer any compensation.We are not responsible for your loss of data from system malfunctions.Calculation results such as values of strength are not guaranteed values.
