If you want to know more, check out these posts. Fortunately, these calculations are relatively simple and straight forward. Calculating the torque that can be transmitted through gear systems is important in machine design. Gear systems are everywhere and fun to design. Remember nobody complains if your gear system lasts forever.

Kleiss Nomenclature b w face width in the mesh d a outside circle diameter, mm (in.) d b base circle diameter, mm (in.) d tip circle diameter, mm (in.) m a proportional top land tooth thickness m b proportional base tooth thickness p b base pitch. Designing to these criteria will put you on the side of caution. Direct Gear Design for Spur and Helical Involute Gears Alexander L. Make sure that your gears are well lubricated as well. My advice to you is this, go conservative! Calculate the maximum load that system can see and use a design factor or 3:1 on yield stress. I wish I could be of more help, but every case is different.

Here are some of the factors that will play a role in calculating the allowable stressĮach of these factors can be very hard to determine. I can only give the lawyer answer: It depends. Unfortunately, I cannot give an easy answer.

We are only thing missing is the allowable stress. With these equations, you should be able to calculate the tangential force. There are many brass and steel materials that could be used for this application. This eliminates most plastics and some aluminum gears as options. This is minimum yield stress of the material required. Completing the calculation with give a stress of 5200 psi. Reports of the calculation are displayed in the Summary of Messages area which is displayed after clicking the chevron in the right lower part of the Calculation tab.From the chart above, we find that a 40 tooth gear with a 14.5° pressure angle will have a Lewis Form Factor, Y, of 0.336. The inputs that fail the calculation are displayed in red (their value doesn't correspond with other inserted values or calculation criteria). Calculation results are displayed in the Results area.On the Calculation tab, enter values to perform the strength check.To decrease or increase number of teeth for first or second gear by one to achieve greater or smaller total unit correction, select Total Unit Correction from the Design Guide drop-down list, change Number of Teeth value, and click Calculate. Change Module to upper or lower value to decrease or increase Number of Teeth. In the Common area, select Number of Teeth option from the Design Guide drop-down list.
