Cantidad y frecuencia de lubricación de los rodamientos de motores eléctricos

Las consideraciones para la cantidad y la frecuencia de lubricación de los rodamientos de motores eléctricos ( y generadores) incluyen lo siguiente:

  • ¿El lubricante es aceite o grasa?
  • ¿El tipo de rodamiento es un cojinete de deslizamiento o un rodamiento de bolas o rodillos?
  • Si es un rodamiento de bolas ¿Tiene sellos, obturaciones o es abierto? En este artículo trataremos todo lo anterior dividiéndolo en las siguientes categorías:
  • Cantidad de grasa y frecuencia de lubricación para rodamientos de bolas y rodillos (rodamientos de elementos rodantes).
  • Frecuencia de lubricación y nivel de aceite (relacionado con la can- tidad) para rodamientos de bolas y rodillos.
  • Frecuencia de lubricación y nivel de aceite (relacionado con la cantidad) para cojinetes de deslizamiento.

Dado que la lubricación con grasa de cojinetes de deslizamiento es muy rara, este tema no se incluye en este artículo. Además, ya que los rodamientos sellados no se pueden relubricar, este tema tampoco está incluido.

Electric motor bearing lubrication frequency and quantity

Article

Considerations for lubrication frequency and quantity for electric motors (and generators) include the following:

  • Is the lubricant grease or oil?
  • Is the bearing type sleeve, ball or roller?
  • If it is a ball bearing, is the enclosure open, shielded or sealed?

This article addresses the above by breaking them down into the following categories:

  • Grease lubrication frequency and quantity for ball and roller (rolling element) bearings.
  • Oil lubrication frequency and level (relates to quantity) for ball and roller bearings.
  • Oil lubrication frequency and level (relates to quantity) for sleeve bearings.

Understand vertical motor bearings

Vertical motors differ from horizontal units in various ways, including their oil-leak risks

Trade press article — Efficient Plant

Bearing construction is a key difference between vertical motors and horizontal motors that are mounted vertically. Vertical motors typically drive pumps using thrust bearings. Horizontal motors rarely have those types of bearings. Understanding relevant construction and configuration factors is crucial when confronting lubrication-related issues that can be associated with vertical-motor bearings.

In oil-lubricated machines, leaks are a frequent and difficult-to-diagnose and correct condition. Due to design issues, there may even be a few machines where oil leaks are simply part of the landscape and not correctable without major modifications. Topics discussed in this article include:

  • Overfilling
  • Checking/replacing sight glasses
  • Proper venting of labyrinth seals
  • Checking/repairing stand tubes (stand pipes)
  • Proper sealing
  • Examining condition of oil sumps
  • Draining oil before transporting
  • Oil foaming
  • Checking vibration levels
  • Checking to see if motor is running off electrical center
