What's the meaning of overturning moment of slewing ring bearing? What are the factors that affect the overturning moment?
As an important load bearing element of mechanical equipment, the performance of slewing bearing is directly related to the safety and service life of the equipment. The overturning moment of the slewing bearing is one of the important indicators to evaluate the bearing capacity. This article will focus on the topic of the overturning moment of the slewing bearing and discuss it from three aspects.
1. What is the overturning moment of the slewing ring bearing?
The overturning moment of the slewing bearing refers to the larger overturning moment that the slewing bearing bears when it is working, usually expressed in N·m. The overturning moment of the slewing bearing refers to the larger torque that the slewing bearing can bear at a certain angle, and it is also the larger moment that the mechanical equipment can bear when it is working. The overturning moment determines the carrying capacity and working efficiency of the mechanical equipment.
2. Factors affecting the overturning moment of the slewing ring bearing
1) Slewing bearing quality
The quality of the slewing bearing is one of the key factors affecting its ability to withstand overturning moment. High-quality slewing bearing typically employ materials and precision manufacturing processes that provide greater structural strength and stability, allowing them to withstand greater overturning moments.
2) Slewing ring bearing structure
Slewing ring bearings with different structures exhibit different performances when bearing overturning moments. The design and construction of the slewing ring bearing structure determines its ability to resist overturning. For example, adopting a wider slewing ring seat, increasing the number of slewing bearings, or using reinforced structural slewing bearing can improve its ability to withstand overturning moments.
3) External loading
The external load on the slewing ring bearing is an important factor affecting its overturning moment. When the external load increases, the moment on the slewing ring bearing increases accordingly, resulting in an increase in the overturning moment. Therefore, when designing and using slewing rings, the required load-bearing capacity must be considered to ensure that it will not overturn when subjected to the expected load.
4) Working environment
The working environment where the slewing ring bearing is located will also have an impact on its carrying capacity. For example, severe operating conditions, such as high temperature, low temperature, humid or corrosive environment, may reduce the material strength of the bearing or cause the performance of the lubricant to decrease, thereby reducing the bearing capacity and anti-overturning ability of the bearing.
To sum up, you should have a general understanding of the meaning of the overturning moment of the slewing bearing, slewing ring bearing quality, structural design, external load and working environment are important factors that affect the overturning moment of the slewing bearing. By selecting high-quality slewing ring bearing, optimizing structural design, reasonably predicting external loads, and adapting to different working environments, the overturning moment bearing capacity of three-row ball, double-row ball, and single-row ball slewing rings can be improved to ensure their stable operation and safety performance.
