A Comprehensive Analysis of the Causes and Prevention of Slewing Bearing Tooth Breakage: Improving Equipment Stability and Lifespan

Slewing bearings are core rotating components in construction machinery, lifting equipment, wind turbine generators, and large machine tools, and their performance directly affects equipment safety and production efficiency. However, tooth breakage is a frequent problem after long-term use, leading not only to equipment downtime but also potentially high maintenance costs. So, why do slewing bearings break teeth? And how can this be prevented scientifically? This article will provide a systematic analysis.

Main Causes of Slewing Bearing Tooth Breakage

Slewing bearings

1. Overload Operation

Slewing bearings are designed with a rated load range. Overloading causes stress concentration on the tooth surface, accelerating material fatigue and ultimately leading to tooth breakage. This is especially true in cranes or large excavators, where improper operation poses a very high risk of overloading.

2. Improper Lubrication

Insufficient lubrication or low-quality lubricating oil leads to direct metal-to-metal contact between the tooth surfaces, increased friction, localized temperature increases, and rapid gear wear. Neglecting lubrication maintenance over a long period is a major cause of tooth breakage.

3. Installation and Adjustment Issues

The installation accuracy of the slewing bearing directly affects the gear meshing state. Uneven installation or preload can lead to uneven gear stress and excessive localized stress, easily causing tooth surface damage or even tooth breakage.

4. Material and Heat Treatment Defects

Inadequate strength, hardness, and surface treatment of gear steel can easily cause micro-cracks under high stress environments, eventually leading to tooth breakage due to long-term accumulation. Uneven carburizing or insufficient quenching are also common hidden dangers.

5. Harsh Operating Environment

High temperatures, dust, and corrosive media can accelerate tooth surface wear or corrosion, reduce load-bearing capacity, and increase the risk of tooth breakage.

Scientific Prevention Measures for Slewing Bearing Tooth Breakage

1. Strict Load Control

Ensure equipment operates within its design load range and avoid frequent overloading. For high-load machinery, slewing bearings with higher rated loads can be selected to increase safety margins.

2. Optimize Lubrication Scheme

Use lubricating grease that meets specifications and regularly check the oil level and quality to ensure adequate lubrication of the tooth surface. For heavy-duty or high-speed operating equipment, consider a circulating lubrication system to improve tooth surface protection.

What are the effects of surface roughness on a slewing bearing?

In industrial machinery, lifting equipment, and automation systems, slewing bearings, as core components for load bearing and rotation, directly affect the operational stability and lifespan of the equipment. Besides materials, design, and lubrication methods, the surface roughness of the bearing is also a crucial factor determining its performance. This article will delve into the multifaceted impact of surface roughness on slewing bearings and provide optimization suggestions to help companies improve equipment reliability and efficiency.

What is Bearing Surface Roughness?

Bearing surface roughness refers to the degree of microscopic unevenness on the bearing raceway surface, usually expressed by parameters such as Ra and Rz. Excessive or insufficient surface roughness will have varying degrees of impact on bearing operation; therefore, properly controlling surface roughness is a crucial aspect of bearing manufacturing and application.

Main Impacts of Surface Roughness on Slewing Bearings

1. Impact on Friction and Energy Consumption

Excessively high bearing surface roughness leads to increased friction between the rolling elements and the raceway, thereby increasing the equipment’s energy consumption and heat generation. This not only reduces bearing efficiency but may also accelerate lubricant aging, shortening bearing life.

Conversely, an overly smooth surface may cause rolling element slippage, reducing rolling friction efficiency. Therefore, maintaining appropriate surface roughness helps achieve low friction and high efficiency operation.

2. Impact on Wear and Fatigue Life

Under high load and frequent start-stop conditions, minute defects on the raceway surface of slewing bearings can easily form stress concentration points, accelerating wear and even leading to early fatigue cracks. Appropriate surface roughness can improve lubricant film formation, reduce direct metal-to-metal contact, and thus extend bearing life.
