In modern industrial equipment, La clasificación de carga estática básica y la clasificación de carga estática básica del rodamiento se refieren a la carga máxima que el rodamiento puede soportar cuando está estático o rotando. are core components for achieving rotary motion, widely used in cranes, turbinas de viento, 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.
Aplicaciones típicas: 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.
Aplicaciones típicas: 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 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
Pequeño, light-load equipment can use ball bearings.
Medium-to-large equipment with high load-bearing requirements should use roller bearings or crossed roller bearings.
