In modern industrial equipment, slewing bearings are core components for achieving rotary motion, widely used in cranes, wind turbines, steel structure rotary tables, and tunnel boring machines. They can withstand not only large radial loads but also axial forces and overturning moments, directly affecting the safety and efficiency of the equipment. This article will systematically analyze the classification and selection points of slewing bearings to assist in engineering practice.

Main Classifications of Slewing Bearings

Slewing bearings can be classified according to the type of rolling elements, structural form, and installation method. Different types of bearings are suitable for different engineering needs and load conditions.

1. Classification by Rolling Element Type

Spherical Slewing Bearings: Use steel balls as rolling elements, resulting in low frictional resistance and flexible operation, suitable for light to medium load scenarios.

Typical Applications: Industrial robots, light lifting machinery, etc.

Roller Slewing Bearings: Use cylindrical rollers, tapered rollers, or crossed rollers, offering high load-bearing capacity, particularly suitable for bearing radial forces and overturning moments.

Typical Applications: Tower cranes, tunnel boring machines, steel structure rotary tables.

2. Classification by Structural Form

Single-row slewing bearings: Compact structure, moderate load-bearing capacity, suitable for small and medium-sized machinery.

Double-row slewing bearings: Rolling elements are arranged in two rows, increasing load-bearing capacity, suitable for medium and large-sized machinery.

Four-point contact slewing bearings: A single row of steel balls can withstand both positive and negative axial loads and radial forces, widely used in engineering machinery.

3. Classification by Installation Method

Internal gear slewing bearings: Gear ring is on the inner ring, commonly used in turntables, rotary worktables, etc.

External gear slewing bearings: Gear ring is on the outer ring, suitable for gear-driven equipment.

Gearless slewing bearings: Rotation is achieved through hydraulic or direct drive, mostly used in high-precision machinery.

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

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.
