reducer size

[Ali]

Hello.

I'm a mechanics student and I have to dimension a conical wheel reducer. for the pinion I did not find any difficulties but I do not know what with the shaft (but solved before). I tried a little alone but I stopped because the wheel is mounted in the middle and I know that it produces the bending moment that is always in between and the binding reactions come out a little low. I don't know how to move on, I've got my whole job attached. Please give me the next steps.

for conical wheel reducers we can use:
- shigley's mechanical engineering design to have the verification parameters according to agma 2003 b97
- bonfiglioli - manual of the reducer to have verification according to iso 10300 which is iso 6336 for conical gears
- iii for all geometric values of gears and for bearing reactions
- skf - mechanical elements perfect for bearing reactionsIn this way it is easy to have the forces that gravate on the input shaft, defined as a swing and the shaft that turns out to be at the center of the bearings.

holding for good the data of the reducer, i.e. input 15kw to 1440rpm and gears m4, z1=20 and z2=32 and band b=30mm you have the following:
- material not necessarily cemented but just a bonded bonificate or in simple carbon c45 reclaimed to heart with surface hardening to teeth
- more than one third of the external generator, so the teeth are bombed. too wide band, it would suffice more tight to resist
- we can afford a service factor agma k0>2

Bye!
Would someone tell me a text by choice and size of the dentate wheels? Thank you all!

Can't you believe the writing didn't appear on the phone?
I'm sorry!
