R175 Battery Bank Charger
« on: February 09, 2016, 02:37:39 AM »
I just completed my latest Project...
The engine is Changfa style R175 and is coupled to an ST-2kw head.
This is the first unit I have built which is directly coupled without a belt drive.
To accommodate the power pulses I sized a shaft coupling capable of 30HP even though the engine makes 6hp.  ;)
For 60hz power the engine must run at 1800 rpm, however I would like to slow it down to 1500 rpm and generate 50hz power.
This should provide quieter operation, lower fuel consumption and maybe longer engine life.
Apparently the IOTA 55 amp charger that the ST head will be powering accepts 50hz power.

There is more discussion on this subject at the following thread...

cheers,

Nice looking project there! Of course it would be nice for us to be able to see the coupling you installed!

Nice setup , I did the same with a Lister SR2 with a 10KW ST head. I used a double chain coupler, with a outside housing the bolt together, around the chain couple. The casing holds grease, so the couple doesn't wear as bad. Funny thing is , you have the same style base as my setup. Old Lister base?

 quinnbrain,

Those chain couplings (I think they are made by FALK ?) are pretty much indestructible. Just like your SR2.
I used a Woods Sureflex coupling. The style with 2 hubs and a Neoprene insert between.
That's why I over sized mine so grossly. If you size them for the engine horsepower the elastomer insert tends to disintegrate, so I used a 5 service factor.

The base is fabricated from a length of 12" wide channel steel and some riser pads to get both machines at the same height.
I had some help with the welding because can't do that very well.

cheers,
veggie

Thanks 38ac,
I must give much credit to a fellow I work with who is a great welder.
He stitched my base parts together with lovely smooth welds.
A very useful skill.
