verification of force agents on a reducing rotism

[elleci]

hello to all, as from title I have a doubt (lieve to tell the truth) on the verses of the forces agents on a reducer. I attach an image of the unifilare pattern of the reducer and a hand sketch of the agents forces. I thank everyone who decides to help me, I realize it's nonsense but it's better to ask that we stay in doubt!

with a scheme so you demand a little too much. where is the engine and the cargo? in which direction do the trees turn? who is motor and who is led? not from the indications if the helical wheels are straight teeth or not and for the conical wheels do not provide any characteristics of the tooth.

I suggest you go look at the site khk gears where you will find all manuals and guides for gears, from basic guides to complete ones for dimensioning, calculation forces, calculation geometries.

on these valuable guides there are formulas related to these examples as well as others.

thank you for the answer and the link you posted
the gearbox is geared to toothless wheels the bike enters from the shaft where the c1 is applied (a1 the one at the top) and exits obviously from the lower one (a4). I have a conical couple in the entrance and then I have three parallel trees (a3 is of reference). My doubt is essentially about the direction of the tangential forces I indicated in the second annex with qij. fixed the verse of the incoming c1 (reported on the drawing) I wondered if the verses I reported were correct.
