tree with pinion

[beretta12]

Hello everyone, I have to make on paper the design of a tree with a pinion mounted via grooved profile, and a pulley for trapezoidal belt mounted via tab.unfortunately they couldn't be present in lesson and the book included does not explain the subject at all well, so I ask who can't give me a hand or some advice.
Thank you in advance, for those who want to attach the delivery.

of these exercises there are a tide held both here on the forum and on the internet.

your exercise is reduced to:
- draw a grooved shaft/hole coupling according to standard
- accessory this design with two dice or something a little more

the other is a tree with bar with tongue seat and mounted pulley + nut.

These things are on all drawing books, on the internet dispensers and on the technical manuals that a responsible person who will go to perform the profession must buy.

It's more than just what you think. put down the drawings and allegiances that we look at them...otherwise it means I have to do your homework and this is not good
