Abnormal noise in a rodamiento giratorio de bolas de dos hileras can indicate a range of issues, from minor lubrication problems to significant component damage. Addressing the noise promptly is crucial to prevent further damage and ensure the longevity of the bearing and the machinery it supports.
Diagnosis of abnormal noise of double-row ball slewing bearing
Here are the common methods to solve abnormal noise in double-row ball slewing bearings, categorized by their underlying causes.
I. Addressing Lubrication Issues:
Lubricación insuficiente: This is one of the most common causes.
y las razones deben ser investigadas y tratadas a tiempo para resolver: Regularly add the appropriate type and amount of grease. Follow the manufacturer’s recommended lubrication schedule. If the bearing has been dry for a while, it may require more frequent lubrication initially.
Poor Quality or Aged Grease: Grease can degrade over time, losing its lubricating properties.
y las razones deben ser investigadas y tratadas a tiempo para resolver: Clean out the old, contaminated, or degraded grease and replace it with fresh, high-quality lubricant suitable for the bearing’s operating conditions (temperatura, carga, velocidad).
Uneven Grease Filling: Inadequate or uneven distribution of grease can lead to localized friction and noise.
y las razones deben ser investigadas y tratadas a tiempo para resolver: Ensure the grease is evenly distributed throughout the raceway during lubrication. Running the bearing for a few rotations after greasing can help with distribution.
II. Resolving Contamination and Debris Problems:
Foreign Particles: Dirt, polvo, metal shavings, or other debris entering the bearing can cause friction, tener puesto, and noise. This often results in a “dust sounding” o “rattling” ruido.
y las razones deben ser investigadas y tratadas a tiempo para resolver: Disassemble the bearing (if feasible and necessary), thoroughly clean the raceway and rolling elements, and remove all foreign matter.
Prevention: Improve sealing arrangements to prevent contaminant ingress. Regularly clean the surrounding area of the bearing.
