Setting up a dupont 50lb hammer. All dismantled cleaned, Lubed and reassembled
I had ordered a 2.5" flat belt of synthetic material from mcmaster Carr. I also ordered a paper pulley to drive the system. The hammer specs called for 375 hits per minute. The motor is a 3 hp and drives at a rpm of 1160. I did my calculations and ordered the pulley at 3.5" for direct drive. Now the hammer works, but far from optimally. There seems to be a good deal of slippage on the 3.5" drive pulley which is understandable mechanically but dissapointing from a performance standpoint. Does anyone have experience with a direct drive motor to hammer setup with these kinds of ratios or is some type of overhead reduction jackshaft necessary. I would rather direct drive due to a premium on space.
