tree with grooved profile

[J ax]

Hi, I have a few questions to ask about the image I attached: Suppose I have a transmission box of this type and I have to connect a grooved end to a tree; How do I do that? Do I have to make a hole in the end of the tree with the same characteristics as the grooved piece that comes out of the transmission? if it is as it is realized from a technological point of view such hole? and how do I represent it?

 

[MassiVonWeizen]

Typically in the chains of the gearboxes there is one or more pages indicating the tolerances of the outgoing trees and their couplings with other transmission organs.qui an example.
mechanically it is realized through broaching

Okay, I'm also looking for a transmission box similar to that in figure: ie at angle with both grooved ends to pass the bike, in my case it also has to act as a multiplier of turns and in particular it has to multiply for 3, you know some brand or some site where I can find them?

hi, it is not really mandatory to perform such processing directly on the tree (unless there are any particular restrictions), you could use something available on the market, like a grooved sleeve to achieve a suitable joint (by tapping on the tree by tab for example) without complicating life so much...
for the brands I come to mind the unimec or red but if you put in google "angular sending" surely you will see a sfilza...

I have a lot of results, but the ones I find have almost all a colleague with tabs, while I would like to know that they would be channeled from both sides :/

 

[MassiVonWeizen]

If you write "grossed angle sending" is easier.
and then you have to read the catalogue well because they are usually supplies on request.
look at the servantmech

search on google also the site of "gb gearboxes" and download the catalogue pdf... :smile:

Ohh I finally found what I was looking for, thank you very much

last question:

profile 1"3/8 z6-1 din 9611

What do these numbers mean? I have sought this rule but it is in German :/

 

[L'Inventore]

is the norm of unification of scanned trees... grooved trees are built according to various parameters according to the standard of unification chosen.
there are various (in 5482, uni 8953 etc.)
generally what you said is used in agricultural machinery or earth movement.

 

[J ax]

I understood this, but could you tell me how to interpret the designation according to this rule? in my case "1"3/8 z6-1" what do they represent? I don't know what he says.

 

[MassiVonWeizen]

the norm is German, but with a fast search come out several pages also in Italian.
I'll give you a hint... search for the designation of the tree omitting the 1 final
but if 1" 3/8 z6 is a clear value it is not that 1 final (to collect between quotes a measure in inches is not the maximum) could be a reference to a note or a crushed value near the other.
you should see the catalog to understand it

 

[J ax]

from what I found by removing the 1 at the end so that nomenclature should mean that the outer diameter is 1'' 3/8 and 6 the number of grooves. Right?

but I found only a pdf in which these dimensions were explained, in all others there is not written: is it so obvious that they all take for granted?

 

[MassiVonWeizen]

two pages to fly12so it is not such a difficult information to find

ogno good designer and designer should have a vademecum or manual underhand. then over time we make a more specific library of pdf and various catalogs

 

[J ax]

Yes but these two pages do not speak of the designation according to din 9611, but according to other norms.

 

[L'Inventore]

I understood this, but could you tell me how to interpret the designation according to this rule? in my case "1"3/8 z6-1" what do they represent? I don't know what he says.

grooved shaft with 1 inch and 3/8 with 6 teeth (or 6 caves)

Try to give an eye here if it can help you. . .

 

[maxstralis]

other site to see evidence bonds & peacocks make corner rhymes will help you ..:biggrin:

last question:

profile 1"3/8 z6-1 din 9611

What do these numbers mean? I have sought this rule but it is in German :/

this din 9611 profile has these characteristics: hole mm 29,67 - 29,72 outer diameter: 34,90 - 34,93 number 6 fins from mm. 8,69 - 8,74.
If you need to achieve it physically you can contact me because I deal with broaching!
