Motor bearings for vertical position
Motor bearings for vertical position
(OP)
Hi Guys,
I am looking for an opinion on the following motor in the V1 shaft down position. Am I working this out ok or is there more to be considered.
Motor 132kw 4pl V1 - 132*9550/1450=869Nm
Vee Pulley approx 46kg 400mm dia, radial force 2000x869x2/400=8690 newtons
Axial force assuming 135kg for rotor 135+46*9.81=1784 newtons
From Motor catalogue roller bearing NU319 on drive end rated at 14700 newtons ball bearing at non drive end is 6319
The rotor has circlips at either end behind the bearings and it has grease plates either end.
The application is a mixer driven by 6 groove belts.
Your comments would be welcome as i am pretty sure the above is not good enough.

Your right it probably is a bit low, I am waiting to get this info from the motor shop I was going on a hunch. Do you mean the two bearings apposing one another at the non drive end ? would it need two bearings as the force is in one direction I don't think there would be space for the two bearings it a std 315 frame IEC Motor.
Thanks
