Overtensioning was one of the first things we checked. If not for component wear, the extra motor current draw from excessively tightened belts is reason enough to check that first thing every time.
We're investigating the shaft material from two fronts. First, we're getting the steel tested...
Thanks. I figured that the usual suspects were to blame, but figured I'd throw it out there to see if anyone else had any additional ideas. I've seen plenty of crack originations from the keyway slots, but didn't want to write this instance off as just another one.
The shaft material is 1045 steel TG&P.
Yes, all of the pulleys were sourced from the same vendor (which made me consider that quality control could be an issue).
Shock loading has been minimal, but I'm glad you mentioned that - I hadn't really investigated that in too much detail, but it's...
Hello all,
I just found this website/forum - seems to be a great resource of talented engineers.
My question relates to shaft failures that I've been experiencing on belt conveyors. We have several different HP motors ranging from 2HP to 7 1/2HP, all with C-Face motors and gear reducers. The...
