A little worm gear machining for you. A friend at work asked if I could make a more durable gear for his wife's Kitchen Aid mixer. Replacement gears are readily available but don't last under the heavy loads of dough hook bread kneading. We make a new one out of a tough strong bronze alloy.
The stock gear in the Kitchen Aid is not a full enveloping worm but a helical spur gear. This is done for ease of assembly and reducing tight tolerances required in assembly for a full enveloping worm gear system. The stock gear is made from a stiff nylon plastic over molded on an aluminum hub. One theory is this nylon gear is also used for some mechanical overload protection of the gearing.
If the testing goes well I would be a good follow on video to make another that is a true helical gear or a fully enveloping worm using the dogmeat helical indexer shown in a previous video.
Cheers,
Tom
