Ahh, I remember my first pull-start End Mill. I believe it was a Troy-Bilt....horrible for cutting spur gears, but worked surprisingly well on grass. Also, Tony, it's done to avoid breakage: The burrs along the tooth edges can often cause breakage when the gear is running, so chamfering de-burrs and extends life, not to mention avoids chipped gear teeth flying all over the joint.

I don't really know much about this, but here is my guess why gears should be chamfered: Both deburring and accurate chamfering is quite important (and each tooth should actually be chamfered on all sides) - Sharp load bearing corners can be work hardened during use, causing breakage. - Sharp corners gets hardened too much during hardening process - If gears are to be engaged and disengaged axially, chamfering geometry is important, oterhwise: - higher wear - Assembly of gears is faster and simpler with correct chamfering geometry - Injury during handling - Less damage during transport - Problems clamping gears in downstream manufacturing steps. (only clamp the disk, not the teeth) - More noise in fast running gear - Post hardening processing requires chamfering to improve process and tool reliablity

Tony, i always enjoy your videos and i learn something, in fact i learn lots of somethings. There is one gigantic problem with this arrangement. All of us viewers (im speaking for all of us, but some may disagree) need more. Im sorry to be the one to break the news BUT, You are going to have to quit your day job. I feel kinda bad about this because im sure your family has gotten used to eating regularly however i think your adorable son has marketable job skills. He needs to get a job. Now i know this may sound a little harsh but in many parts of the world he would have been working for a couple years already. He just needs to buy a lunch pail and head off to work. He has been selfish for far too long. You need to get into shop much much more often. Last i heard these videos you make do not make themselves (at least i don't think they do).Even the cat seems to do as it wishes. Rent out the cat on an hourly basis as either a mouse trap or a companion animal. If you stop hosing it down with the pest repellant it will more than likely survive all the previous sprayings and live to fight another day. I'm sure your lovely bride will feel bad as your son goes off to work with his new lunch pail and decide to pitch in for the greater good of mankind. I'm sure when the rest of the family is doing their part and are ALL(accept you) gainfully employed you will have at least 8 hours daily clot shop. If you include the interruptions because of lunch breaks and potty time, you may even have 9 or mors hours in the shop. I personally feel their employment is a small price to pay for our (your viewers) entertainment and enjoyment. They may not think so at first, but give it, say, three to five years. Then ask how they feel about the new arrangement. Deposit all the paychecks in an account that you alone control. We wouldnt want any money spent frivously, like designers clothes for the little lady or expensive underwear even. All that can be purchased at thrift stores for pennies on the dollar if you shop wisely. There is nothing wrong with second hand underwear, i personally would send it through the washing machine once or twice if it was for my wife. It doesnt have to look new as long as it's fairly clean. For the kids, buy the clothes a few sizes larger than they currently wear and make sure that what you buy is durable. They will grow into them as long as they get enough calories daily. Now you need to be careful with your wife, women can be really sneaky about clothing. She may say that she's put on a little weight and needs new clothes. Humbug, cut back on her caloric intake and in maybe 8-12 weeks she will fit right back into her coveralls. You have to remember that the sneakiness in females is genetic. It may seem that she does it intentionally, it is not her fault so don't punish her too severely. Maybe sending her to bed without dinher for a few weeks will train the genetics right out of her. It may take a litgle longer than a few weejs but she will come around and be thankful for it. I'll send along some more instructions if this doesn't work out 100 % the first go round. So in the mean time, please get out into the shop and make some more videos for us. We really need them. some folks think i'm nuts but in truth, Imonlyhalfnuts really. 😁 seriously, thank your family for giving us so much of your time. you sir are awesome and from what i can tell, so is your great family.

Corner bevels and leading edge bevels assist in side meshing as stated above. Reduced burr formation reduction causing that may cause galling of adjacent plating or gears also as stated above. Corner bevels also assist in oil and debris escapement in gears walled in on both sides. Preventing hydraulic loading and the forcing of walls away from gear. Can reduce noise in some applications. Makes them look and feel way better. Some of these factors are not present on a lot of gear applications and as such you wont see the corner bevel on things like crown gears or 'Bevel' gears, or gears with a shank or standoff.

@@another1commenter770 makes good points. In tough ductile materials, chamfers are important to prevent damage to 90 degree corners, which will raise a bruise adjacent to the ding (which, as he points out, may then damage the part in contact with it); in brittle materials, they're important to prevent chips or cracks when the gear is accidentally knocked or dropped. As other have said, these chips can migrate through the entire gearbox (they may not break off at the time of the damage) causing mayhem when they pass through the mesh or get jammed in bearings. These rules are true not just for gears but for machined parts generally. Also a perfect 90 degree corner is unsafe for human contact.

I will probably never cut a gear in my life... But I love this!

The ToTstronaut...The genius is truly in the details. Also the wide view. And the editing. And font selection. Most parts, really.

The chamfer on the corners of the gears is because that is a weak area. Under load any shaft deflection can put very high loads on the corners of the teeth, and for hardened steel gears or cast iron the edges would simply break and you end up with bits of hard material passing through gears, so best to remove them from the start by putting a chamfer or radius on them. Not really a problem on aluminium or nylon gears. Finally something I learned during my apprenticeship turned out to be useful...

It is stupid how much better at math I am now that I am a machinist. Every time you cut you need some kind of math. If I have a 12 foot piece of A36 that needs to be cut to 10 inches I divide and add at the same time using an equation, length of stock÷(length of piece+blade thickness)=useful stock length. This tells me how much material I can actually use from a piece of stock. But first i have to convert the stock length from feet to inches. So i multiply the feet by 12 inches to get 144 inches.So 144÷(10+0.125)=144÷10.125=14.2222222222. I cant use the extra 22222s at the end because they represent what i have left on the stock so I can get 14 pieces of 10 inch part blanks per stick of A36. And the customer wants 100 pieces. So I divide 100÷14 which gives me 7.1428571429 which just means 7 full sticks and one that wont be cut up completely. Lets assume that the customer actually sent the 8 sticks I need and I dont have to tell my boss that I need one more stick because we're also out of 0.5 inch A36. NOW WE CAN CUT oh wait i have to set the stop, ok stops set at 10 inches. NOW WE CAN CUT METAL! This is just the first step in most jobs period.

a tip for when you're cutting smaller gears (like for clocks, as I do) cut in a little bit with your parting tool. This doesn't need to be the whole depth of the tooth, just a slight, but it'll decrease the chance of the teeth getting mangled when you're parting it off after you've cut the teeth. bigger teeth usually are strong enough, and the involute gearshape helps as well, but making cycloidal teeth the base of the tooth is quite small, especially when making pinions (Z

Two guesses on why gears are chamfered: 1: To reduce oil flinging, without the corner the oil is more likely to fling onto the other gear. 2: To remove a stress riser. Helps keep your gear from looking like a Hockey Player.

@Gottenhimfella

5 жыл бұрын

Stress risers (for everyone's information, not as a rebuke to this post) arise (ha!) from INTERNAL corners, not external ones. So the root fillet of the gear tooth moderates the stress raising tendencies at the root, but there is no such need at the tip. Sharp external corners are delicate by a different mechanism: because they're not well supported by the part, because they present a small cross sectional area (which *does* expose them to increased stress, but only in proportion to the area, like any contact stress) and because they're protruberant by nature and hence damage prone.

@StanislavG.

Absolutely LOVE your work. One of my top ten favourite KZread channels. Been watching almost daily for the last few weeks 😀

The bevel on the gear depends on the application. You don't always have to do it, and you can always add it later. 1: It helps retain oil by adding surface area and changing geometry. When they're flat and tightly meshed, they foam up the oil faster. That little bevel lets surface tension do its job, and then oil on the following rotation will clean out any junk from the prior turn. Same thing for when gears are submerged where they mesh away from each other. You'd be amazed how hard it gets to turn a shaft under that kind of condition. 2: On geartrains with lots of shock loading and harshness, like on motorcycles, the teeth chip on the corners of the tooth tips.

Best videos on the Internet. Combined with humor most will never get. Pure awsome!

Because of these videos I now have a home made idler/reverse gear for my little lathe. When I need a left hand thread cut in ten years I'll be sure to tell everyone to thank Old Tony.

Should I wait for the re-upload before commenting?

The chamfer is necessary, because it´s more aerodynamic. No need to thank us, we are here to help....

Old Tony you need to be writing, directing, acting and editing your own big budget Hollywood movies. But on second thought, we would dearly miss your KZread channel so please continue your brilliant work on KZread.YOU'RE ONE OF A KIND!😁

Thanks for these videos, Tony. I don't have much for tools so I've been making them from scratch building up to a point where I'm gonna have to cut some bevel gears. That thing about concentricity error is golden! Honestly, there's a very high probability of failure, so I'll take every bit of info I can get lol. Thanks again! 👍😊👍

I love the McMaster tip, I steal dimensions from their drawings all the time

I'm not a machinist and i have no idea what are you doing... but i love it all!!!!!!!!!!!!!!!

You, good sir, have truly gone off the deep end. I love it.

Best channel I use to watch. I love the good humor in every videos!

I just watched it, second times. It’s a great video, superbly done. I don’t have a dividing head, never even worked with one. Two gears were done by me only, during a life time, using the lathe as a shaper. I am planning to make a special gear without dividing head, most likely never will be done. Thanks again for this most enjoyable video, I can appreciate the work you put in and the excellent photography. Bob

@7.29 the reference to Cogswell’s Cogs (again from the Jetson’s) made me grin. I’m compelled to re-watch your other videos again to search for more of these Easter eggs. You certainly put a lot of effort and humor into your videos. Much appreciated.

Dang Tony. I literally said out loud watching this; 'holy crap, that's some amazing filming' (the static cutting head, in particular). Your sense of cinematography is criminally undervalued. Well done, chap, well done. 'Top Secret: Cogswell's Cogs' Lolololol. Brilliant.

You make me wanna leave the comfort of my warm home and go to that cold shop and cut some gears... Thank you This Old Tony!

Absolute gold. Thanks for sharing your talent for teaching and video making!! Best regards from Brasilia, Brazil.

Two ways of checking you actually got it right. love the videos Tony.

Re: teeth chamfer - first thought is to ease assembly when inserting / meshing gears. Second guess would be clearance for gear oil / grease to pass around.

That was a great video. Now do a worm gear. No cheating using a tap for a hob. Nice square threads. Then put it in a cute machine to show it working. Due in 30 days. Grade depends on fit and finish as well as fancy video editing. This project will be 1/2 your grade this semester.

@ThomCat316

That's not all that hard. Make worm and hob as one piece on lathe. Remove, heat treat, reinstall. Gash wheel blank using slitting saw to provide a start for the hob. Mount wheel blank on workholder on lathe cross slide, turn on lathe, slowly feed wheel into hob until desired depth achieved. Lap on worm if desired. Part off hob. Matched worm and wheel!

You uploaded this video precisely at the same time I started to think about making a gearbox, how serendipitous.

Re: The CHAMFER. It will reject foreign objects better, and more importantly, protect the gears when they are ever so slightly misaligned. But I'm pretty sure you knew that! A thing of beauty. Thanks.

How serendipitous

More on gears and sprockets if you have ideas for them please! Make gears for all the things! How to make helical cut gears? Herring bone gears? How to make gears if you only have a lathe? Gears?!? MOAR GEARS!!!!

As a wood worker who came from a piano shop that loved nothing more than talking people's ears off about nonsense they wouldn't even begin to care about. I have to say when you cut yourself off into the next scene, shows great discipline and talent. I tip my cap.

I could resist anymore. I subscribed. You way to entertaining and I love your humor.

KZreadrs take note: this is how you make a video entertaining - stealing top secret data from cogswell , getting a custom space suit monogrammed by NASA - no one does it better .
