i am looking at couplers of connection my motor to my grain mill, and one of the biggest questions i have is do lovejoy couplers like thishttp://www.amazon.com/Lovejoy-Size-L075-Coupling-Bore/dp/B003HIWOQA/ref=sr_1_6?s=industrial&ie=UTF8&qid=1325952162&sr= 1-6
have a set screw?
or will this on work, even though my drive shaft is 1/2 inch and my driven shaft is 3/8 inchhttp://www.amazon.com/Boston-Gear-Coupling-Diameter-horsepower/dp/B004NYAKV8/ref=pd_ecc_rvi_cart_4
The latter looks very similar to the set I use between gear motor and BC mill, but at around half the price I paid to Surplus Center.
There are set screws in these in addition to keyways. I put a drop of blue Loktite on the screws and I set them on the flats on the shafts at each end. Works fine...
sweet, i couldn't tell if the lovejoy had a set screw or not, for my stuff i need the set screw. thanks for the surplus center link, i appreciate it, brew on!
When you buy your lovejoy, you will buy three pieces. One coupler sized for the motor shaft, one sized for the mill shaft and a "spider" to couple them. And yes, they will have set screws.
Look on ebay for the lovejoy i just ordered one a few days ago all 3 pieces where $14 shipped.
