in this case it works, but you have to have enough space.

in my opinion yes! :Thank you! What about the quotation that drawn by me can go?

there are two negative aspects in your mounting hypothesis: I see you have adopted a very small diameter cutter that is not likely. in practice should be larger and therefore would increase the stand-up of the bearing, which is not healthy. the bearing must support well on the shaft with a pull of a few mm. therefore better a workmanship with candle cutters that can minimize the spaces without having to adopt a spacer.

But let me @ndrearicci what does this question have to do with the discussion?

we had already talked about blocking the bearings in the discussion so I thought it might be as a questionBut let me @ndrearicci what does this question have to do with the discussion?

I actually have no experience with mechanical processing and I have no idea what milling diameter is most suitable. Thank you, I suppose I made the quarry with a candle cutter.there are two negative aspects in your mounting hypothesis: I see you have adopted a very small diameter cutter that is not likely. in practice should be larger and therefore would increase the stand-up of the bearing, which is not healthy. the bearing must support well on the shaft with a pull of a few mm. therefore better a workmanship with candle cutters that can minimize the spaces without having to adopt a spacer.

Don't worry, it's just a dotty thread, but not too much.we had already talked about blocking the bearings in the discussion so I thought it might be as a question

hello to all, reading your discussion on forums I asked for a detail, why andrea published a design of a screw gear, I wanted to ask if a mechanical designer apart from being engineer or expert, if besides limiting itself only on the design can have also the faculty to perform calculations for the mechanical resistance of the individual commercial components of machine, for example, to make me understand better, if you should choose a motor gear based on the required power ratio, to calculate the performance of the or are not calculated to resistance because so much being the commercial motor gears automatically were already verified in the reducer box and therefore not to choose them according to the module calculated by the verification of mechanical resistance?. . Thank you all. car

when choosing components from business, calculations and verifications are carried out by manufacturers, if you have doubts you can contact them.
the calculations and the various verifications, resistance, fatigue, etc., are carried out its important components that make up the machine or the plant, according to the regulations in force in which they are understood.

It makes no sense that you, buyer, search for a gear motor, because you already buy it certified to resist the stresses you choose for. Except you wouldn't even have all the information available to verify it.hello to all, reading your discussion on forums I asked for a detail, why andrea published a design of a screw gear, I wanted to ask if a mechanical designer apart from being engineer or expert, if besides limiting itself only on the design can have also the faculty to perform calculations for the mechanical resistance of the individual commercial components of machine, for example, to make me understand better, if you should choose a motor gear based on the required power ratio, to calculate the performance of the or are not calculated to resistance because so much being the commercial motor gears automatically were already verified in the reducer box and therefore not to choose them according to the module calculated by the verification of mechanical resistance?. .

If you want to dimension, draw and verify a reducer you must make the designer in the company that produces it.

why then raga in the community I see many demands x the sizing of the gearboxes, if you choose it only and just then why do you do the problem on the dimensioning? Help me understand, please. . .

but cmq the important components as you say can also be dentate wheels, I did not understand what you mean for important and commercial components, at least if you can explain the difference between them, so I take at least the doubt please.when choosing components from business, calculations and verifications are carried out by manufacturers, if you have doubts you can contact them.

boy, some gearboxes or by size or by type are not found by trade and should be built ad hoc!why then raga in the community I see many demands x the sizing of the gearboxes, if you choose it only and just then why do you do the problem on the dimensioning? Help me understand, please. . .

in a special plant or machine, there are the components you buy (from trade ) type, gearboxes, motors, screws etc. then there are the details you need to design, verify and build, you have to do so respecting the regulations that will be different if you are planning a crane or press.but cmq the important components as you say can also be dentate wheels, I did not understand what you mean for important and commercial components, at least if you can explain the difference between them, so I take at least the doubt please.

because, besides what said from @ pietro2002 on ad hoc construction for their own needs, it is one of the standard exercises that are given to students to put into practice how taught and in fact most of these discussions are open by students.why then raga in the community I see many demands x the sizing of the gearboxes, if you choose it only and just then why do you do the problem on the dimensioning?

Moreover, those who will go to work on bonfiglioli or red et analogue these knowledge must have

therefore in line with what has stated @pierto 2002 therefore if for example in the building houses like x es bonfiglioli, red, etc. the ad hoc construction can be realized also according to the correction of the teeth and therefore considering various parameters to consider it would be easier to build and design it instead of going to choose it?because, besides what said from @ pietro2002 on ad hoc construction for their own needs, it is one of the standard exercises that are given to students to put into practice how taught and in fact most of these discussions are open by students.

Of course, if you build special machinery and you build gears directly in the cashier, you can do them as you think, push on profile shifts and various corrections, as well as materials and treatments.therefore in line with what has stated @pierto 2002 therefore if for example in the building houses like x es bonfiglioli, red, etc. the ad hoc construction can be realized also according to the correction of the teeth and therefore considering various parameters to consider it would be easier to build and design it instead of going to choose it?

typically the firms that make gearboxes have their catalogs and realize the production in series. If you have to build a special gearbox for a mill, you design it and build it, it will be a unique piece. the speech corrections a little from this discussion.therefore in line with what has stated @pierto 2002 therefore if for example in the building houses like x es bonfiglioli, red, etc. the ad hoc construction can be realized also according to the correction of the teeth and therefore considering various parameters to consider it would be easier to build and design it instead of going to choose it?

I'll give you some examples:but cmq the important components as you say can also be dentate wheels, I did not understand what you mean for important and commercial components, at least if you can explain the difference between them, so I take at least the doubt please.
commercial components that do not need to verify (in the sense that it is not necessary to calculate that the respective construction parts are suitable for the function for which they are intended): cylinders, gears/pignions standard, bearings, chains, jacks
important components you need to check: frames and supporting structures, all the cinematic mechanisms in the sense that the standard reducer, the calettator, the cylinder do not have to compute constructively, but its size si; stresses and loads of the various components both commercial and not, safety scales, molds, cereti types of containers, etc. these are some exempts that have come to mind, but it is impossible to create a precise case even for the great variety of mechanics
