Speed Reducer Pulley In The Uk

[frasermade]

Hi all -

I've just recently acquired an Adler 167 and will soon be putting a servo on it. I have been searching high and low to find info on making my own speed reduction pulley but can't, for the life of me, find a layman's instructional to do it.

I know I need a certain ration 1:3, I know I need bearings and another belt, but I can't find anything on where to get pulleys, bearings and belts in the UK.

Any assistance is greatly appreciated,

Best

Gordon

It's not easy to find speed reducers for sale in Europe. Perhaps Andreas in Sieck.de have some for sale still. I bought some of him before and they where reasonably priced. I have had both Adler 67 and 167. Currently I have the Durkopp Adler 267-373 with an Efka DC 1600. With a new 600 to 750 watt servo motor you do not need any reducer on that machine. A reducer on top of the new strong servo motors will be to much for that machine, it will simply be to strong. That's the setup we use on the heavy stitchers like the 441 and 205-370 machines. I installed a reducer and a 600 watt cobra servo on my Pfaff 345 H3, a similar machine to the 167 but with a cylinder bed (I had a reducer laying around). Now I want to take it off again. The setup is way to much for the machine and easily knocks it out of timing if accident happens. The Pfaff has no safety clutch, your 167 normally has one. Nevertheless, a reducer will be a waist of time and money. Use you money to buy a good motor instead. https://www.college-sewing.co.uk/Industrial-Sewing-Machine-Motors sell many good motors. The best deal will be a Ho Hsing G60 needle position servo motor to about 160 £.(it's not displayed on their site) http://leatherworker.net/forum/index.php?showtopic=65042 that's a Japanese professional motor that is more than strong enough for your machine without any reducer. That's a Japanese motor to a Chinese price

It has needle position, needle always stops down position. Heeling the pedal brings it in correct top position. You can go stitch by stitch and motor have great low speed control. It's a labor saving solution. I currently have such motors on two of my machines, and could not do without them.

Good luck.

I have just bought a servo motor and needle adjustment from College, and wish I'd done it ages ago. No need for a speed reducer, or change of pulley, at least for me.

Single stitch now possible, and easy to control.

Thanks all - I'm going to get a servo (JK-563A-1 220V 750W 1 HP SERVO MOTOR WITH NEEDLE POSITION) from College-Sewing. It looks to be the best one and I've seen a few on youtube.

All I'm looking for is like 1-3 stitches per second. I'm such a new-hat at this that the clutch motor is making me mad.

I take it this motor will give me what I'm after?

I also have two JACK servos from College Sewing in the UK, both 750Watts and both have added a speed reducer. One is for my 133K3 and on the other one I have a Singer 111. Maybe overpowered for the 111 but it will only kick the safety clutch when you hit something really hard at higher speed so thats not an issue for me since I´m sewing quite slow (and it never happened). If you need a needle positioner the Jack servos do not work with an added speed reducer. I have no experience with the Ho Hsing G60 but sounds like a good one.

I think it doesn`t matter if a 750Watts or 550Watts Servo or 370Watts clutch motor kicks off the clutch when you hit a hard spot. The resistance of the clutch is always the same. I´d say thats what the safety clutch is meant for.

Mine is the Jack 563A-1, and the only problem I've found is getting used to the silence after a clutch motor.

I recommend the Ho Hsing G60. You get that for the same price. It has a needle position system that works. It's also possible to build on a system control box on it later. Then you can add all kinds of equipment like pneumatic footlift etc. Together with Efka, Ho Hsing is world leader on sewing motors. And a motor that the Chinese copies allot. It's torgue and lowspeed control it's all about. Watt is a measurement on full speed. Why buy a copy when you can get the real thing for the same price? And with support. Does the needle position work on the Chinese motors, sometimes perhaps? Just a question. That's what they struggle to get right.

I use Efka, but when I need a new reasonable priced motor I will buy the G60, it's half the price in the UK, here its twice as expensive. I have tested it and it works great.

Thanks for the input Tor

Do you have a UK supplier of the Ho Hsing?
