Selection Of The Mixer's Horsepower And Speed Is Critical To The Performance Of The Mixer.

Marion uses a data base of thousands of known applications to design each drive train specifically for the application. For unique applications, data obtained from controlled experimental testing (with our test mixers) is used to determine the appropriate horsepower for the production sized mixer. Although Marion can custom design to virtually any type of power train specifications, our typical drive train package includes:

gear reducer

Gear Reducer

  • Shaft mounted with torque arm for precision alignment
  • Helical cut gears for speed and torque conversion
  • Dual tapered bushings for simplified maintenance
electric motor drive

Motor

  • Cast iron body for rugged industrial applications
  • TEFC or explosion proof frame construction
  • High locked rotor torque for starts under load
  • Inverter duty for variable frequency drives if required
pillow block bearing

Bearings

  • Externally mounted pillow block roller or spherical ball bearings
  • Non-expansion type on the drive end and expansion on the opposite
  • Welded stops permanently hold lateral position of bearings
drive shaft

Shaft

  • Solid core shaft to transfer torque and withstand bending stresses
  • Turned, ground and polished for straightness and finish
  • Machined keyways with radius corners for reduced stress risers. Straightness of shaft varified following weld operation
