I am familiar at setting up these kinds of drives. The ball mill pinion bearing is held and we will run mag center, stop the motor and return to mag center and set the coupling gap to manufacture's specifications by axially moving the motor assembly. The coupling, by design will allow around...
We will run the motor to check rotation and establish mag center. What kind of tolerance is acceptable and how does this tolerance effect motor life and reliability.
The motor has only sleeve bearings and the OEM manual says that mechanical center is adequate, but am wondering if aligning within a few thou of mag center would improve reliablity or extend the motor life.
Am aligning a 2000 HP 200 RPM motor driving one of our small ball mills. What are the tolerances for setting mag center and will a tighter tolerance impact reliability or extend motor life? How are level tolerances?
