How do you design involute gears?
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. A new involute has to be drawn for each size of gear in your system. To begin drawing, lay out three concentric circles: One at the pitch circle.4 mar. 2020

How do gears turn?
Gears are wheels with teeth that slot together. When one gear is turned the other one turns as well. If the gears are of different sizes, they can be used to increase the power of a turning force. The smaller wheel turns more quickly but with less force, while the bigger one turns more slowly with more force.
What is simple gear train?
A Simple Gear Train is a number of Simple Gear-Pairs in series. Each shaft/axis has only one gear. Use a Simple Gear Train: •To increase the distance between the input and output shafts and still use small gears. •To reverse the direction of the output shaft on a Simple Gear-Pair.
