I attach geometric construction table conical wheels.
The corner of the foot is deltaf.

Can you explain how I have to do the calculation of the primitive cone semi-angle?
delta1 what is it?

Can you explain how I have to do the calculation of the primitive cone semi-angle?
delta1 what is it?

You could get there. . delta1 is the angle reported to z1, while delta2 is the angle reported to z2. for z2 delta2 worth 90-delta1

but zeta1 and 2 are the teeth numbers? !

 

[meccanicamg]

but zeta1 and 2 are the teeth numbers? !

z1 = tooth number related to wheel 1
z2 = tooth number related to wheel 2

.... connect brain, check that the wires are not to mass, feed.

Numbers 1 and 2 are reference to wheel 1 or wheel 2.

in jargon the dense wheels are called with z followed by the number

is it possible that on the skf site do not find radial ball bearings to a crown to be mounted on a 30mm shaft?

 

[PierArg]

is it possible that on the skf site do not find radial ball bearings to a crown to be mounted on a 30mm shaft?

No, because they exist. see:

I go here, select the bearings to a crown, but then the diameters are all smallhttp://www.skf.com/skf/productcatal...list.jsp?maincatalogue=1〈=it&showchapter=true

at least exsre able to look down and understand that there are n pages to scroll??? We refuse to answer the next questions of this kind :finger:

the problem is that I don't see the list of pages to scroll:frown:

It was a firefox problem. I opened the page with chrome and now you see

I understood this...considering tgdelta1=z1/z2 =delta
I chose the pinion with 20 teeth, since the ratio 1:2 the other wheel will be 40. Now how do I proceed? I'm sorry. .

you have the tabellina with all formulas and you get all the parameters. just a calculator and use pumpkin...and read!!! :biggrin:
delta = arctangent (z1/z2)That's what you did.

...I forgot: press on on/ce if the calculator is off

... ps: there is the calculator manual, wikipedia and google if you just can't do the reverse function of a trigonometric function

Mechanicalmg, have you verified that the function in question is invertible? Otherwise you can not do what you said...ahahah:biggrin:

I would invert your neurores very willingly and find that by calculating the limit for x that tends to + inphile it is always zero less asymptotically:tongue:

 

[meccanicamg]

for those who lost the book use of the calculator there is This is beautiful

and I've been delta=20
angle dedendum =2.3
considering the pinion 20 teeth with ratio 1:2
time deltaf =20-2.3
is it correct?

 

[meccanicamg]

z1 =20
z2= 40

and I've been delta=20 26.56angolo dedendum =2.3 2.56considering the pinion 20 teeth with ratio 1:2
time deltaf =20-2.3 24What do you mean, Corretto?

But you can't even use the calculator? It's getting serious. starts to worry seriously. recheck in everything

z2= 40

when you find the angle dedendum:z is the number of teeth of the wheel taken into consideration?

 

[snaroz]

when you find the angle dedendum:z is the number of teeth of the wheel taken into consideration?

Yes, if you are considering conduct is conduct, otherwise the pinion

 

[xxi]

in the exit shaft I put the braces on the right of the wheel and on the left I have to put a radial bearing to compensate for the spins
is it correct?

to prevent that I still do not have the right knowledge to choose the bearings.
