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?
@williamstyers42645 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.

Don't knock the method if you haven't tried it, because it works very well. For a more robust gear, use an ACME thread tap! Or even better, make a properly proportioned involute (straight-sided teeth!) hob. Relief is only required on the tooth OD. The concern with this method is getting the right number of teeth, as the number can vary by +/- one tooth. To make an accurate worm gear with the required tooth count, such as I made for an indexing head, gashing of the teeth will be required with very accurate spacing and depth of the individual gashes. This would be followed by the Free Hobbing process, where the gear blank turns freely, driven by the hob itself. Worked out very well for me.

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.

The gear hobbing set-up described herein is neither new nor primitive. In fact it is described in the bible of milling machines, published by the Cincinati Milling Machine Company in the middle of the last century. The basic set-up is named free-hobbing, and is useful only for worm gears. When cutting small gears by this method, it is best to make 3 or 4 gear blanks because the number of teeth produced may vary by +/- 1 tooth! This may be ok for some purposes, but if an accurate gear with a certain number of teeth is required, the process needs a little refinement. I've used this refined method to hob a worm gear for a small indexing head, which turned out very well indeed.

Well done, although brass needs no lubricant and using such can, and did, cause the chips to stick to both the tap and the work piece causing issues. I saw you were using a brush to deal with the chips sticking to the brass gear; that's not necessary if you don't use lubricant. Also the tap, as with any tools used on brass, needs to be brand new and sharp, i.e. never used on steel. This advice comes from a Trade Qualified Fitter and Turner (Mechanical Engineer). Great job, great vid :).

Nice! Have not seen that done before.

Pure luck if after 1 rev, the teeth marks matched up. You could end up with half teeth and machine everything off. Good idea but for accurate work ie meshing gears, the work piece has to be driven in synch with the cutter.

Igotknobblies The method demonstrated is called free bobbing. The workpiece is forced to rotate by the helix angle on the flank of the cutter. Works fine for light power transmission, probably not consistent enough for accurate positioning.

webtoedman yes, I quite understand the theory behind free hobbing, like I said, it's pure luck if the first and last tooth of the revolution of the workpiece are a perfect tooth distance apart, and like I said, if they're out by 50%, you could end up chopping all the teeth off.

Igotknobblies Unless he calculated the diameter exactly.
@EJaunez6 жыл бұрын
PaintHerWhite but wich diameter the initial or the final? I think he calculated the initial, because the center of the gear seems a little flat than the borders.

Well, you lost all respect with the IKEA wrench but then you gained it all back and more by teaching this old machinist a new trick. Well done.

Generally I would agree, but I can't/won't pass up the chance to rib a fellow machinist for using his wife's adjustable wrench on a KZfaq video. Name on the tool doesn't matter if it does what you need. Maybe the good natured joke got lost in translation....

D=P/sin(3.14/z) Это формула для определения наружного диаметра для этой шестерни. D - диаметр в миллиметрах P - шаг в миллиметрах Z - число зубьев

You can use a threaded rod, type as the tap.. If You used M10 tap, use a M10 threaded rod..

I used to grind gears at caterpillar, and on a larger scale, its hobbing, just on a much smaller scale. If you were to start at the leading edge of the work piece, and run all the way down to the bottom edge, it would actually be a decent hobby grade straight cut gear, run multiples at different diameters and you could, theoretically, build an entire gearbox.

I was a Cat tech for 30 years. We have probably touched some of the same gears. The various machining techniques Cat used always intrigued me.
@bradvanbibber58834 жыл бұрын
I think a standard bolt used to drive this gear would strip the gear quickly if subjected to any amout of torque. Most bolts onlt have 60% thread engagement. If you threaded a rod of the correct diameter you could get the thread contact percentage up quite a bit and have more consistent threads that wouldn't chew up the gear as quickly.

Thanks, this video appeared just at the right time for me. A simple jig for my mini mil or mini lathe and I should be able to cut a large worm gear. Thanks again. Now then, I wonder if a matching die could cut the matching worm?
