How to design a working and fully editable rack and gear mechanism, identify which characteristics control the gear design and why the module, number of gear teeth and pressure angle are important. The relationship between addendum and dedendum in terms of clearance is also discussed.
Design a linear gear rack mechanism using Solidworks
This video gives a practical demonstration on how to detail the involute curve, gear tooth profile, pitch circle, circular pitch, dedendum, addendum, whole depth, addendum circle, clearance circle, root circle, base circle, pressure angle and how it relates to rack design
