Why root clearance is required for gear meshing

"why required root clearance for gear mashing?"

"So that they 'mesh' instead of "mash".

Gear Wheel Tooth Profile from Wikipedia.

You need a copy of:

Machinery's Handbook 28th Edition Toolbox: book and ebook ..
Yes, you will have to pay for it, but just think, you will never have to ask strangers about this again.

gears are usually designed to take the maximin torque near the center of the teeth. the inner and outter parts of the teeth are used for meshing the teeth as the gears rotate.

Dear Mr.pathak5000,

Root Clearance = 0.225 x Module of the Gear.

Let us say the Module of the Gear is 30, then Root Clearance = 0.225 x 30 = 6.75 MM.

Pl. Refer any Standard Gear Design Book.
