SORRY FOLKS, I am stopping this blow-by-blow method as other work demands time вЂ“ comment below if you want it finished

One with the diameter of the pitch circle minus twice the modulus, minus one third of the modlus (this will be used for the bottoms of the teeth)ДЇor the crucial base circle, the circle from which the involute will be вЂunwoundвЂ™,.

One with the diameter of the pitch circle plus twice the modulus (this will be used for the tops of the teeth).

To begin drawing, lay out three concentric circles: 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.ДЄ new involute has to be drawn for each size of gear in your system. If you donвЂ™t know your pitch circle diameter, read вЂworking out what you needвЂ™ belowвЂ™.ДЄssuming you do, there is also a nice graphical way to work out pitch circle diameter, and then draw the involute. The imaginary circle around which the imaginary string unwinds in gear creation is called the вЂ base circleвЂ, which is a special thing in gear creation.Д«ase circle diameter = (pitch circle diameter) xВ cos(pressure angle) If you wind string tightly around a cylinder, and then unwind it while keeping it taught, any point along the unwound string describes an involute as it unwinds. Properly designed involute gears mesh nicely, operate smoothly with predictable back-lash.ДЄs far as I can see, they add little or no velocity variation to the output shaft, and nor do they add much torque variation.Д®veryone describing the shape of an involute вЂ“ at least, in my experience вЂ“ mentions string. Rarely will anyone need to play with other types, such as hypoid gears. When you read about designing gears, you are almost always reading about вЂinvoluteвЂ™ gears.

This bit is about how to lay-out the gear tooth profile, for how many teeth to have, scroll down to вЂ Working out what you need. but it might be better to try the presentation resource mentioned above.ДЇrom here on, there is a bit more detail, missing all the stuff that you donвЂ™t actually need to create a 20В° >16 tooth metric gear by 3D printing (cutting a gear using special tools adds more complexity). You can have (almost) any gear ratio and centre-to-centre distance if you are prepared to use arbitrary modulus and pressure angles, but stick to common modulus values and 20В° pressure angles if you want your gear to mesh with a buyable gear.Д«ased on this last item, here are a bunch of things where, unless you are really lucky, you will have to trade-off at least one to get a working gear pair:Д«ig warning:В Whilst all of this is true to the best of my knowledge, everything written here is only for gears for trivial use вЂ“ look elsewhere to design any form of load-bearing or safety-related gear.вЂ Pitch circleвЂ is the diameter of a pair of plain cylinders that would have the same gear ratio and centre-to-centre distance as the intended gears.In fact, if they are different diameters, to mesh perfectly they will have different shaped teeth. This does not mean that they will have the same shaped teeth. To mesh properly, involute gears only need two things in common: modulus and pressure angle.Involute is a type of shape, very important to most gears, andВ easily drawn.Now for some other useful gear facts if you are to diy: However, it does not provide a format that DesignSpark Mechanical can directly import.

Gear generatorВ is an on-line gear generator websites by Abel that is easy to use, and you can download CAD files from it for a small payment.

The author, Matthias Wandel, will also sell you a programme to run on your Windows computer. This one handles вЂundercutвЂ™, which removes the gear-interference problem that prevents the easy creation of gears with fewer than 17 teeth.

Woodgears is an excellent on-line gear generator website which is very flexible (frankly, amazingly flexible) and has this excellent associated video.

Also, there are two that will design gears for you.CAD package Fusion 360 will draw gears for you вЂ“ so you might want to stop reading here, and download that instead.The slides mention ShigleyвЂ™s Mechanical Engineering Design, which maybe what they are based on. The best diy gear information source, of all the many many videos, websites and documents that I read to design my gear pair, this presentation was far clearer than the rest, and had extra information.
