Question:medium

The minimum number of teeth on the pinion in order to avoid interference for $20^\circ$ full depth involute system is

Show Hint

This is a standard reference value in mechanical design: - For a $14.5^\circ$ full-depth system $\rightarrow$ Minimum teeth = 32 - For a $20^\circ$ full-depth system $\rightarrow$ Minimum teeth = 18 - For a $20^\circ$ stub-tooth system $\rightarrow$ Minimum teeth = 14
