Well I doubt I will ever need a worm gear but you just opened my mind to a whole new area of machining ideas

I need to make something like that , i have tread dial with a missing gear that runs in the 4 TPI lead screw . I have a 4 TPI Tap but what size round do i start off with ?

How do you ensure the gear meshes when the worm has turned 360, or did you just keep pushing it into the tap until they do? In which case each movement of the transverse will cut on a new circumference and the new cuts will be out of sync with the previous.

Love the work you do on the lathe m8, old school yes but you know what your doing. Keep the vids coming

When working for my uncles in their small shop we used to manufacture small worm gears for a company that used 1/2-13 threaded rod to make their worms. We cut the gears on a Barber-Coleman #3 gear hobbing machine using a 1/2-13 tap. Obviously you need to calculate the proper diameter of the gear blank but using only the downfeed of the machine it produced beautiful throated worm gears by the hundreds. Nice video.

how to fix the gear diameters For the screw of pitch?

@williamstyers4264

5 жыл бұрын

@@user-ec3ij6mt3p We converted the 1/2-13 UNC threaded rod to the comparable diametral pitch which is 40.83 DP. Using standard worm gear calculations for the 100 tooth gear (number of teeth/diametral pitch) give a value of 2.449 inches for the pitch diameter. The worm gear in this case was throated so standards call for the throat diameter to be the pitch diameter + (2 X addendum). As this was a non-critical application we chose to treat the addendum as one half of the whole depth of the thread (in this case .0472 inches) and add that to the pitch diameter. The outside diameter of the worm gear is pitch diameter + (3 X addendum) so the finished bronze gear blank ended up being 2.520 inches. OD = PD + (3 X addendum) Hope this was not too confusing.

@Ol' Camo Somemthing that I have figured out over the yers is that there are many different kinds of machinist. You have folks that make one off parts, they tend to have tight tolerances and can take more time to achieve prefection and people that are what I call production machinists who focus more on speed and just stay between the linse as perfection only adds cost. I find that someting these two groups but heads a bit. There is also a line between manual and CNC machinists or even mill and lathe machinists, they to can be a bit tribal. Point is that if your making parts for a living your a machinist hell you could only use a file to make em and still call yourself a machinist the only real question is are you a good one and even that could be subjective.

@Dustin Eward Knurling seems to be really hard on bits. But yeah, somehow it magically sorts itself out and looks good even after bad math, lol.

How would you ensure that the point where the threads meet on the new piece are equal to the rest of the threads? It seems as you cut deeper into the material, the point where the threads are cut at the deepest point may not be equal given the circumference. In essence, the point where the new teeth begin to be cut off by the tap

Out-f**kin-standing!! I would have never thought of using that setup to cut a gear...and yet, with the center keeping the tap from deflecting, it makes perfect sense. I'm amazed by your machining cleverness.👍👍👍

Do you need a piece with a certain circumference for a certain pitch for the threads to line up when completing a full revolution?

Legend has it the lathe is still running nonstop for 7 years .

How do you calculate the diameter of the blank for the gear? Very impressive video as usual of course.

Really clever!Did you have an application for this gear? I am curious about the final shape of the teeth: Are they somewhat involute? I would presume that they might be due to the entry and exit of the stock into the tap. Now I am tryna think of some sophisticated application of a gear like this... Thanks!

How do you match the disk (to be cut) circumference with the worm drive teeth rate to be cut?

Well that's nifty. The engineers are always asking us to do nutty things with little to no proper tooling. Always good to learn something new. This is going to be categorized under what I call "old guy tricks" I've learned many many things like this from guys close to retirement many who I have since replaced at various jobs over the years. Also handy if I ever need a small worm gear made at home with my little hobby lathe. I'm sure I could figure it out.

The gear pitch and circumference ratio should match, or else the meeting point at the end of first round will not match...

How do you make sure that the teeth line up on the first pass? Do you calculate the circumference of the gear in increments of pitch of teeth on the tap?

Am I right in assuming that the diameter of the piece must match or be an exact multiplication of the tooth per inch of the tap? And if that is measured on the outer diameter and That the thread spacing must technically be closer or tighter on the inside of the concave?

I don't know about primitive. That's pretty good.

A nice volume knob for the old hi-fi.

Now I will never buy a gear motor again. Just make my own reduction gears! THANK YOU!

To get it to match up on 1 complete round is there a certain diameter for a certain size tap?

I assume calculations are needed to ensure you cut a whole number of grooves on each rotation given the radius, thread pitch, etc.

Loved your idea.. As a learner I will be adopting this in a future. Many thanks

using this method you are machining the gear with varying pitch diameter because you are using the cross feed. What I did was to machine the od of the blank with a groove matching the id of the tap and a circumference which is a multiple of the pitch of the tap, Then bring it in with cross feed onto the end of the taper of the tap. Then use the saddle to feed the gear onto the tap. The cut is done always at the same diameter on the wheel.

Hi Jamie, I didnt change the tap, it is in original condition as You can buy it in store..

That is a great idea. I wonder if it would hold up on a capstan chainsaw winch?? Has the gear been in use and if so how is the durability? Thank you for sharing this video.

How do you ensure that the number and width of teeth end up being exactly 360 degrees around the gear? It looks like its going to be random where the last tooth ends up and it might start running over thr first one when it comes around. Not a bad technique for making a sector gear I guess.
