Worm gears

Post by Martin »

First, sorry for my poor English skills. :(

I would like to know at what point will there finally be worm gears?

Had already asked one and a half years ago after. ::)

Will the program as a multi-language.

this would simplify many things.

Unfortunately, I am now in an age where you unwilling to learn a new language.
So I do not always understand everything. ???

Would be nice to know, which is also being worked on.
and this would significantly increase the customer group.

Until then, great work from you!
Greetings, Mart

Hi Martin:

    There is no real development list of when a feature will become available. It usually depends on how many ask for a feature, how possible is it, and
if its possible to easily build one from code to make the output usefull.  I have no yet reall figured out how exactly one will make a worm gear, while I
agree they woudl be usefull, the actual output code to make them is difficult to do with a standard 4 axis machine, its more of a 5 axis device.

    I dont think you'll see worm gears in the near future, not by end of this year anyway.. I think I have enough future code to write that it will be
into next year before worm gears will be seen.

3D printable worm gears might be useful, although they'd be limited to lower power.

I'm still working on getting back to a Roots with square shafts (and a working CNC router for tabs...) and not sure my vote for one is worth much right now.  Googling "3D printer worm gear" found quite a few hits, including some stls, so there might be something else to use.

Yes, thats one of my issues, a 3d printed worm would wear otu pretty quick Id think.. or wouldnt print very well.. And that woudl leave us with another
issue like bevels, but worse. We can print a working bevel, Ive printed several, but cncing them is much more difficult.. worms are also hard to machine and also hard to
print, which makes them questionable as to if time should be invested in them..
  Bevels I intend to cure with an engraving module, more of a 3d waterline type of cut..worms cant even easily be solved that way..

But Ill ruminate on them while Im on my hiatus...

I'd be ok with generating a hobbing tool for now.

Hi Guys:

It is near the top of my list for types of gears..

Perhaps there could be tools for designing, machining, and printing worm wheels that work with standard threaded rods and maybe standard acme screws. Print the wheel, buy the worm.

Jerry:

Depending on the worm you have that now, many worms use a normal spur gear as the wheel,
the worm is just a single gear tooth wrapped on a cylinder. Fully enveloped would have the spur
gear turned down a bit on its tooth center, but still very simular..

I did try to model some worm gears for acme screws a while ago.  They weren't mechanically great. (http://www.thingiverse.com/thing:270309)

If you know the thread form of the drive screw, and you have a lathe it should be relatively easy to use the same thread form to make a primitive hobbing set up like this: https://www.youtube.com/watch?v=J0o3W4_LRBw

Hi,

Just looking if there is the possibility to make worm wheels wit Gearotic, as I see at the moment not.
Art say that is must maybe a 5 axis job, but in this article they do it with the 4th axis, I think with a form cutter (40 degrees?)

Hi Rien:

  That mating gear to a worm I suspect can be done, its the longitudinal worm thats harder.. but I do think a form cutter could
do it. Just a matter of making the Gcode for the cutter.. I see that as a kind of threading operation using the 4th axis..

Hi Art,

I think it is no problem for the most of us to make the Worm in the lathe, dimensions from Gearotic.
And the Wormwheel in the 4t axis with code from Gearotic.

If you have a lathe and a mill it may be easier and faster to build a hobbing jig for making worm gears.
