The repair looks really good, but in that last shot I can tell just by looking at it the weld didn't get proper penetration. There shouldn't be a harsh line like that. I can't say if the entire weld didn't, but that edge sure didn't. The entire filler surface probably should have been cleaned via a little grinding prior to welding.

@2stroke1971 4 ай бұрын

That edge might just be a bit of overhang from the lathe operation, made more obvious by the contrast. I get the same out of my cast iron gears..I can never get the weld dead flat with the rest of the gear without digging into the side of the rest of the gear so I wind up with that. Back lash in the carriage I suppose.

Other than insufficient cleaning and poor welding, using an angle grinder to shape the welded tooth will never give him the correct angle on the drive or coast side of the tooth. If the angle is too steep, it will load the next tooth in line excessively. If the angle of the tooth is too shallow, it will load the previous tooth excessively. Either instance will result in more broken teeth. Better cleaning, shielding adjacent teeth from splatter and using a high nickel rod would give the best possible life. Using a form ground carbide cutter in the lathe toolpost, he could have broached the tooth to be EXACTLY like all of the other teeth.

He needed a runout tab on the side so the start/stops would be outside the tooth edge and would machine off.

It all depends on the gear tolerances. If these are loose-fitting gears, this repair may be adequate. But if the gears are tightly fitting, eyeball grinding is not good enough. The gears are likely to wear and clank and grind, perhaps wearing in to better conformance, perhaps to worse. Only time will tell.

@ripd97 7 ай бұрын

I didn't think about that, but you are correct, I saw a few episodes on manufacturing machinery, and some of the gears they were making had to be within a certain tolerance, guided with a computerized cutting machine and checked within a tenth of a millimeter. 😦😦

@PeterChapman-rg6gr 7 ай бұрын

if you look at the gear you will see that there is a lot of wear on one side so there is no way that it could ever be described as a "close fit" gear train.

There is nothing even remotely "New" about this method of repairing broken gear teeth. My family were doing this in their workshop back in the 1920's ( that is over 100 years ago) on steam engine gears. In those days about the only welding rods that were available were early Quasi-Arc rods and the AC power source was very crude. After the war we were running nearly 100 engine driven Lincoln, Petbow and Hobart welding sets. The only difference being that welding power source and welding rod technology has come on in leaps and bounds since then. Ps back then there was no such thing as an "Angle grinder" but we had the some of the very first Flex grinders that came into the UK back in the 1960's. So the gears had to be set up on the "shaper" to re-cut the tooth profile.

Primero no es algo nuevo, lo hacen en muchas partes del mundo. Segundo, este tipo de reparaciones son "pañitos de agua tibia". Sirven para salir de un apuro momentaneo. Eventualmente esos dientes deberan repararse nuevamente puesto que las propiedades de esos materiales no es la misma que solo soldar y esmerilar. De hecho con solo calentar el material ya existen cambios importantes en la estructura metálica. Normalmente las ruedas dentadas son aceros de alta dureza, generando resistencia al desgaste. Al calentar la zona, posiblemente produzca una cambio de fase, y lo q antes era resistente ahora ya no lo es.
