WHAT TO CONSIDER WHEN SELECTING A GEAR REDUCER OR GEAR MOTOR

By Bill Tobias

Many factors go into making the correct decision when selecting a new gear reducer. We must begin with the following basic information to accurately make the correct selection.

WE START WITH:

  • Speed—how fast does the application require the output shaft to turn?
  • Torque—what is the torque load requirement?
  • Overhung load—how external radial loads are applied to the output shaft may require more gear load capacity, and therefore, larger gears.
  • Duty cycle—how long will the gearbox operate before turning off? Depending on life requirements, intermittent duty applications can utilize smaller gearboxes.

THEN WE ANALYZE OTHER FACTORS, SUCH AS:

  • Weight, temperature and environment
  • Special coatings or enclosures for harsh or food and beverage applications
  • The correct mounting position so the unit receives proper lubrication
  • Calculations for correct horsepower requirements

A failure we routinely see is the use of a reducer with a c-face direct mounted motor in reversing applications, these failures can usually be solved by simply changing it to a c-face coupled motor instead. Making the correct selections in the beginning will help assure long life and reliable performance.
