minimum teeth

A pair of spur gears is required to maintain a velocity ratio of $1: 2$. The module of the gears is 10 mm and the addendum is 10 mm . If the operating pressure angle is $15^{\circ}...

It is desired to avoid interference in a pair of spur gears having a 20 o pressure angle. With increase in pinion to gear speed ratio, the minimum number of teeth on the pinion

The minimum number of teeth on the pinion to operate without interference in standard full height involute teeth gear mechanism with $${20^ \circ }$$ pressure angle is

For full depth of involute spur gears, minimum number of teeth of pinion to avoid interference depends upon
