Стальные конструкции are widely used in modern buildings, industrial plants, and infrastructure projects due to their high strength, посадка в теплице, and high construction efficiency. Однако, the reliability of steel structures depends not only on design and construction but also on the rigorous quality control system of the steel structure factory. This article will delve into how заводы стальных конструкций ensure the durability and reliability of every delivered product through comprehensive quality management, safeguarding engineering projects.

Why is Quality Control of Steel Structures So Critical?

Steel structures are typically the load-bearing core of buildings, and their safety directly affects the stability and service life of the project. Substandard materials, improper welding, or inadequate anti-corrosion treatment can lead to a shortened structural lifespan and even safety hazards.

For engineering contractors, project managers, and end customers, understanding the quality control process of steel structure factories is an important reference for ensuring investment safety and the long-term stable operation of buildings.

How do Steel Structure Factories Achieve Rigorous Quality Control?

1. Strict control over raw materials

High-quality steel is the foundation of the durability of steel structures. Steel structure factories typically conduct multiple tests on incoming steel:

Chemical composition analysis: Ensuring that the steel meets national standards (GB) or international standards (ИСО). Mechanical performance testing: such as tensile strength, yield strength, and impact toughness, to ensure load-bearing capacity.

Appearance and defect inspection: checking for cracks, коррозия, and surface imperfections to prevent potential problems from entering the production process.

Through rigorous raw material selection, the factory lays a solid foundation for subsequent processing and welding.

2. Precision Machining and Welding Management

The machining accuracy and welding quality of steel structures are core to structural durability and safety:

Подвергать механической обработке CNC: using high-precision CNC cutting, гибочный, and drilling equipment to ensure accurate and consistent component dimensions.

Standardized welding processes: each weld follows AWS or ISO welding standards to ensure uniform welds free of porosity.

Welding quality inspection: using X-ray inspection, Ультразвуковое тестирование (UT), and penetrant testing (ПТ) to detect welding defects.

Through high-standard machining and welding management, the strength and durability of steel structure components are effectively guaranteed.

In modern industrial equipment, Мы все знаем, что независимо от того, какой подшипник are core components for achieving rotary motion, widely used in cranes, ветряные турбины, 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.

Типичные приложения: Industrial robots, light lifting machinery, п.

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.

Типичные приложения: 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, п.

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 Bearing Selection Guide

Choosing the right slewing bearing not only ensures stable equipment operation but also reduces maintenance costs and extends service life. The following factors should be considered when selecting slewing bearings:

Load Type and Size

Маленький, light-load equipment can use ball bearings.

Поворотные подшипники 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. Однако, tooth breakage is a frequent problem after long-term use, leading not only to equipment downtime but also potentially high maintenance costs. Так, 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, повышенное трение, 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, твердость, 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, пыль, 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.
