Therefore the diameter of the pinion gear will be around 34mm.A great way to transmit mechanical power from one place to another or to increase or decrease power (torque) or increase or decrease the speed of something.The problems are always that to make efficient gears needs quite a lot of drawing and mathematical skill as well as the ability to machine complex shapes.

Add Tip Ask Question Comment Download Step 4: Working Out the Size of Everything 2.We can now easily sort out some simple maths to make our gear a. How bigsmall do we need the gear teeth to be, (diameter) - The smaller the gear the smaller the teeth need to be. All the teeth that are going to mesh, (connect), together must be the same size so calculate your smallest gear first. Lets start with a gear tooth size of 10 mm I want a gear with 5 teeth on it so the circle will be 10 x 10mm round (circumference) 100 mm To draw that circle I need to find the diameter so I use a bit of maths and a calculator a divide the circumference (100 mm) by Pi 3.142 This gives me a diameter of 31.8mm I can draw this with a compass and then fit exactly 10 circles 10mm diameter round it with my compass. If your able this is easier to do with even the most basic drawing software. If your using software you should be able to rotate the tooth circle round the main circle and will need to know how far to rotate each tooth - This is easily calculated by 360 deg the number of circles so for our 10 circles 3601036 deg rotation for each tooth.

This can be cut in wood or metal with basic hand tools, saws and files. It is easy to repeat this process for any number of gears as we need them. Add Tip Ask Question Comment Download Step 6: You Have Your Gear 6 Because this semi-circle shaped gear tooth is easy to cut you can do it with hand tools, a sabre (jig) saw or even a coping saw. In the past I have made a template of 9 or 10 teeth from plywood and use it as a guide for my hand router and cut the gear teeth with little trouble. If you have access to a laser cutter these can be cut from 3 or 5 mm acrylic and work well down to very tiny sizes.

You need to select a diameter that will suite the teeth spacing on the belt. Sketchup is perhaps the best known although has a steep learning curve. A 2D CAD tool is perhaps best for drawing these gears. I assume this continues youre idea 0 mechanicalengineercalculator. However I perhaps did not express the idea quite as succinctly or precisely as I should have. Text corrected. (i will restrain myself from commenting on your spelling.) 0 jdorrington rickharris. I am using a couple of gears for an exhibit panel.you turn the gears and see the text exposed in the window in the gear Will be fun for the kids to turn it and find out the message:) Cheers 0 rshugrue. The shaft of the servo that rotates it is off-center, obviously inside the arm.
