De vez en cuando un usuario final quiere utilizar un motor diseñado para montaje horizontal en posición vertical. En este artículo, trataremos algunos factores mecánicos clave que deben ser considerados cuando se utiliza un motor horizontal con rodamientos de bolas en una aplicación en la que trabaja en montaje vertical. La Figura 1 ilustra un motor horizontal en posición vertical con el eje hacia abajo.

Los factores clave incluyen:

  • Capacidad de carga axial del rodamiento que soporta el peso del rotor.
  • Peso del rotor
  • Peso de los elementos acoplados al eje de salida
  • Empuje axial de los equipos de impulsión acoplados directamente
  • Trayectorias de lubricación de los rodamientos
  • Retención del lubricante de los rodamientos
  • Orientación del eje: Hacia abajo o hacia arriba
  • Protección contra ingreso
  • Fijación axial del rodamiento de empuje
