What pulleys and timing belts do I buy from sdp-si???
Hi all, I need to knock up a timing belt reduction like the one in the photo. I was thinking of around a 6:1 ratio. ie 10 tooth and 60 tooth pulley. I would like to use a 3/4" belt.
How are those plastic pulleys with the aluminium inserts? are they okay for cnc use?
I want to buy from www.sdp-si.com. I had sent them an email telling them what I have do and what I need for my plasma table.
http://www.cnczone.com/forums/showthread.php?t=4900 (Started to build my plasma table.)
They replied back that they do not select parts for people and that I would need to get an engineer to do that. Pathetic support for customers. So anyway. I need to find some one to get me the part numbers from the sdp-si.com website for me to make a belt drive.
the centre distance is to be 250mm.
1/2" drive shaft internal diameter
Allloy or aluminum prefered
What diameter of bore do you need. Any preference for GT2, L, H , L, XL, MXL or pitch?
Bore is for 1/2" shafts.
Don't know what size is best or what pitch is best. All I know is that I think that 1/2 wide belt will be too small and that I might have to use a 3/4 wide belt.
Off track to your question I know but have you tried http://www.smallparts.com.au They are in Mansfield, Qld.
For the GT2 5mm pitch pulleys with 1/2 inch bore, 15mm belt width (0.691 inches), the best ratio is about 3 to 1. What would you like to do?
smallparts.com.au actually use the sdp-si.com stuff. My email ended up getting directed to smallparts.com.au
I still like the idea of going with sdp-si.com as the shipping is direct and it is also faster to get here.
I like what you have sugested. I have had a problem with the whole plasma table vibrating like its convulsing after having a hard night on the grog.
So I decided to see what would happen to the noise/vibration if I was to disconnect the motor away from the pinion. And what I found out was that the really loud noise disapeared.
So the vibration must be transfering to the rack from the motor. Now I am thinking that by using a rubber timing belt this vibration will not be transfered to the rack???
I like the idea of the stuff that you reccomended ViperTX. I will now try to find all the part numbers to order the stuff that you reccomended.
