Simple box-style speed reducer for an industrial sewing machine 

I'm glad the video was helpful. I do love this reducer!

glad it was helpful!

Nice! With my very small pulley going to the machine, I did need to tighten that belt quite a bit. Someone was thinking when they designed this simple and very effective reducer!

Yeah--whoever invented it should get a big raise!

@@weekenddistractions where can I get one?

@@ThoughtFission Hi. I got one from Toledo Sewing.

Awesome--you'll like it!

I think that is better since you can take the belt to the machine off without having to take the other one off. I couldn't make it work that way--maybe I didn't try hard enough!

Look forward to your results. My rumble is there, but it isn't too loud, but it would be nice if it was whisper quiet. Isolators are a good idea.

@@weekenddistractionsso i unmounted everything and reinstalled but this time with the rubber isolators between the table and the speed reducer. It helped tamp down on the noise a bit but i still can hear and feel a low rumble. The noise in my opinion almost makes my machine feel like an old car or some kind of army tank. The feel over all of the low rumbling vibrations of table makes seem like my machine heavy and clunkier rather than nimble and quick if you know what I mean. Sewing is a chore with that feeling. When i had everything apart i turned the speed reducer pulley by hand it didn’t seem to me like it made any noise by itself. The motor being turned by hand also didn’t seem to make noise. I have come to the conclusion then when everything is put together and the belts are tightened the entire assembly seems to vibrate in unison and it all gets transferred to the table. I did notice when i tightened the belts much tighter the sound dissipated a bit. My motor has a really badly designed hinge where there is slack in pin holding the hinge. That is possibly not helping as the motor pulley needs to be tightened extra hard to make the motor stop vibrating and transferring vibration up through the speed reducer and on to the table. So in conclusion rubber isolators between table and speed reducer helped a bit but not much. I think instead what I’m gonna end up doing if i cant get used to this setup is just removing the speed reducer and putting a smaller pulley on the motor instead to slow down my machine. That would help slow it a bit down but it would not be ideal in terms of torque on thicker materials. Oh well I really don’t know why it’s so hard to make sewing machine motors that go slow and have allot of torque.

It's a little harder as you say, but still quite useable.

Thanks for commenting and watching! I would be nice to just have a servo motor capable of very slow speeds without the need for a reducer, but this solution is pretty nice. I'll take a peek at your playlist!

I got this one from Toledo sewing.
