C. Use the 10 DP Spur Gears. pdf and the Gearbox Cale was in the Design Project folder to create a combination of gears to achieve your determined RPM (IF] or an RPM that falls between your upper and lower limits (18). Below is an example of a 600 RPM to 18 RPM gearbox. Note that the gear clusters that are the same color are fixed to each other, are turning at the same RPM, and in the same direction. The velocity ratio of the gear box can be found by dividing the input RPM by the output RPM or by multiplying all of the VH's in the right-hand column. Both are shown below the chart. (600/18 = 33.333) (5x1x3.333 1x2= 13 333) The Gearbox Cake risk has a blank for you to add gear tooth and the example. If you achieve your desired RPM, but are turning the wrong direction, add a gear of the same number of teeth as your last gear for a 1:1 VR and a direction change. There are rows for plenty of gears, try to use the least number as possible to help eliminate complexity and cost. You can, but are not required to, create a depiction of the gear clusters either in excel or by hand. I have added it for demonstration. There are multiple correct gear combinations to fulfill the design criteria TEETH CW 5.000 120 COW 1 170 CW CW CCW 1 A. The output RPM of your gearbox RPM B.
