good morning to all, can someone help me in this design? i find myself with a professor who cannot help me do this exercise

[meccanicamg]

There's a deafening silence from our student. . .

we hope he's interested.... it's his post. I would have already received at least a dozen notification mails.

mha.. Perhaps he hoped that the forum enthusiasts would serve the solution on a silver plate.
the title of the post says long.. a professor who cannot help him? :unsures:

the track has been given to him.. You just have to put in a few numbers.

I'm not gone, I just don't spend all day in front of the pc

you think about it, but the whole class is struggling. my professor treated the subject only for five minutes, not even making us a sizing

So carlos, do you have a draft to share?

I tried to do the exercise with different data, assuming some values

I'm sorry, I don't want to insist, but the gears made them? how do they measure and verify? as you said before yes.

here now, it is not a problem to apply lewis .... but understand that 270 degrees are not a turn and therefore development is not a primitive diameter round. . .

that puts us 5 seconds or 70 seconds doesn't need anything in this exercise....unless you check it hard and wear according to norm and impose a number of hours of operation....but I don't think that's what you're asking...unless you know the whole subject.

Why with different data? What changes? procedure one must be.

I must also do the fatigue dimensionalization and in this case I must use omega that is obtained from the angle in radiants, fract the time in seconds.

performance: wheels well work what it means? if rectified 0,99 if you cut creator 0,95 approximately.

because I have the same exercise as my classmate, not now I have only the photo of his exercise (equal to mine with only different data)

ok, se devi fare anche ad usura ok.

I hypothesized a performance of 0.8 to be able to calculate the power applied on the rack.

I'm sorry, do you have to solve yours and cover yours? who does reasoning? him or you?

 

[carlosiltopochegira]

the main problem is what I can't understand which angle speed to use

 

[meccanicamg]

with a 0,8 yield means that the teeth are cut by hand with the pond or however you have many losses for friction and dry work.

we have reasoned together

 

[carlosiltopochegira]

with a performance 0.8 means that the teeth are cut by hand with the pond.

So you recommend using a higher performance?
