RDG 30VSM-Parts Needed

Hi,

I have an RDG 30VSM which has mashed its gears. Could someone please point me in the direction of where to get replacements, please? Looking at the forum, it seems they are similar to the Warco WM16, but the gearing looks different? Thank You.

Have you tried RDG ?

I have emailed them and await a response.

Unfortunately no joy. The answer was "we got them from the same places as Warco".

Isn’t a 30 the same as a wm 18?

if so i think i have a spare off to look now…

Is it a 56 and a 31 tooth?

if so i have one

You can get an idea of what gears you require by measuring the OD of the mating gear, and counting the teeth, as well as the other dimensions..

The gears are likely to be Module, so Diameter in mm / (Tooth Count + 2) i= Module.

EXAMPLE

OD = 27.5 mm / (20+2 ) = 1.25 (Module ) for a 20 tooth 1.25 Mod gear.

The answer may well be 1.5, 1.25 or 1.

You could look at other importers to see if they import a similar machine (Possibly only in a different paint scheme) who could supply a replacement.

Likely places, once you have measured the gears, and knowing the tooth count of the damaged gear, might be Chester, Axminster Arc Euro, SPG, Amadeal etc.

Bear in mind that some machines, although superficially identical, may differ in detail. Depending on the manufacturer,, the keyway, for instance may differ, (Say 4 mm against 3 mm),

If all else fails and only the bore is different, you might have to bore out and bush a close approximation to get the machine running again.

Ultimately, you could approach someone like HPC, or Davall or Reliance gears, but their gears are likely to be costly and need modification to fit your machine.

The only other advice that I can give is not to work the machine quite so hard in future

The plastic gears are the weak point in the drive train and fail safe to protect other components, akin to a shear pin..

These are hobby machines, not industrial machines designed to be worked hard 8 hours every day!

When that gear got damaged on my mill, I went to HPC and bought steel gears and made my own replacement ! In my case quieter as well. The moulded gear was off centre and made a thumping noise as it ran.

The single Large Helical is 39. Large is 56 Fixed to 30

Thank You. I do not know!

Know anyone with a 3d printer ?

Yes, if someone has the .stl files? That would be fantastic

If you look on thingiverse for G0704 gears there are both spur & helical listed , may fit

Having no luck at the moment with gears, I am looking at fitting an AC motor with belt and pulleys. The current DC motor is 1100W, what is the AC equivalent please? Any links to suitable belts? Thank You.

Are you sure on the fixed pair of gears?

i have a set off a 30vsm spare and they are 31 and 56 and the helical is 39

Hi Ian,

I have messaged you. Thank You

Having recounted. You are correct! that gearing is what I need. THANK YOU!!
