The slewing bearing  coefficient is a vital parameter in the field of engineering. Single -row rotating support is a key component widely used in various industrial machinery and equipment. It is responsible for supporting and turning important mechanical components. The rotating support coefficient directly affects the operating efficiency, accuracy and life of mechanical equipment. This article will explore the significance, influencing factors, and how to optimize the performance of the rotary support to improve the performance of mechanical equipment.

1. What are the friction coefficients of the rotation support

The concept of the slewing bearing coefficient: The friction coefficient refers to the ratio of friction between the relative motion between the two objects and the pressure of the contact surface perpendicular to the contact surface of the two objects. In the rotary support, the friction coefficient affects the force required for the support during the rotation process and the size of friction. The high friction coefficient can cause greater friction loss in mechanical equipment, which affects the rotation efficiency and heat of the equipment.

Second, the rotary supporting friction coefficient influencing factors

The rotating support coefficient is affected by various factors. The choice of materials is one of the main factors that determine the friction coefficient. The friction coefficient between different materials is very different, so you must choose the right material carefully when designing the backup. The surface roughness and lubrication conditions will also affect the friction coefficient. The smoother surface and effective lubricant can reduce the friction coefficient, thereby reducing friction loss.

3. Method of handling the rotary supporting coefficients

In practical applications, optimizing the rotating support coefficient is critical to improving the performance of mechanical equipment. First of all, reducing the friction coefficient can reduce the energy loss of mechanical equipment during operation, improve rotation efficiency, thereby saving energy and reducing operating costs. Secondly, optimizing the friction coefficient can reduce the wear of support, extend the service life of mechanical equipment, and reduce maintenance costs.
Back support 1. Select the right material

According to the specific application scenarios and working conditions, select materials with lower friction coefficients, such as high -performance polymer materials or coating materials.

2. Surface treatment

By surface processing technology, improve the smoothness of the support surface, reduce surface roughness, and reduce the friction coefficient.

3. Lubricant selection

Select the lubricant suitable for working conditions to maintain the lubrication state of the support surface, and reduce the friction coefficient and wear.

4. Optimization of load distribution

Reasonable design support structure, balanced load distribution, avoid local overload, and reduce friction.

5. Temperature control

Properly control the working temperature of the support to avoid increased friction coefficient caused by overheating.

The slewing bearing coefficient is an important parameter that affects the performance of mechanical equipment. By selecting the appropriate material, optimizing surface treatment, lubricant selection, and load distribution, we can effectively reduce the friction coefficient and improve the operating efficiency and service life of mechanical equipment. In the future engineering design, we should continue to pay attention to the research of the rotary support coefficients, continuously optimize the design, promote the development of engineering technology, and provide more efficient and reliable machinery and equipment for all walks of life.

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 its bearing capacity. This article will focus on the topic of the overturning moment of the slewing bearing and discuss it from three aspects.
the
1. What is the overturning moment of the slewing bearing?
the
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 bearing
the
1. Support quality
the
The quality of the slewing bearing is one of the key factors affecting its ability to withstand overturning moment. High-quality supports typically employ materials and precision manufacturing processes that provide greater structural strength and stability, allowing them to withstand greater overturning moments.
the
2. Support structure
the
Slewing bearings with different structures exhibit different performances when bearing overturning moments. The design and construction of the supporting structure determines its ability to resist overturning. For example, adopting a wider support base, increasing the number of support bearings, or using reinforced structural supports can improve its ability to withstand overturning moments.
the
3. External load
the
The external load on the support is an important factor affecting its overturning moment. When the external load increases, the moment on the support 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.
the
4. Working environment
the
The working environment where the support 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.
the
To sum up, you should have a general understanding of the meaning of the overturning moment of the slewing bearing. Support quality, structural design, external load and working environment are important factors that affect the overturning moment of the slewing bearing. By selecting high-quality supports, 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.

During the use of construction machinery equipment, various problems can not be avoided. Sometimes the turntable bearings suddenly break, which will not only affect the production progress, but also cause huge losses, and may also danger. What is the reason why Hengguan Xiaobian will analyze the reasons why the lower turntable bearing broken phenomenon will be analyzed today.

Reasons for the break of the rotor bearing
1. Material problem

The phenomenon of rotor bearing breaks can be said to be a major quality problem of this part. The rotor bearing breaks refer to the inner and outer ring of the inner and outer circles of such bearing, mainly because the tensile strength, yield strength, and impact toughness of the material are not up to the standard. Mechanical properties of making such bearing materials. The main material of the rotor bearing is carbon structure steel. 50mn and 42CRMO are commonly used in this industry. 50mn mechanical performance: (1) tensile strength σb (MPA): ≥645 (66); (2) Lading strength σs (MPA): ≥390 (40); (3) elongation rate Δ5 (%): ≥13: ≥13 ; (4) Sectional contraction 断 (%): ≥40; (5) impacting AKV (J): ≥31; (6) impact tough value αKV (j/cm2): ≥39 (4). When the turntable bearing work at a normal use temperature (-30 ° C to 70 ° C), it can basically be sure of the factors of the material problem.

2. Processing heat treatment

The production and processing process needs to be heat treatment of the rolling roads. The heat treatment fails, resulting in low surface hardness. The hardness layer penetrates into the wall of the rotary bearing structure or reaches the rotary supporting wall, which changes the mechanical performance of the internal and external circles. The value becomes smaller and the material becomes crispy.

3. Design structural problem

After the design structure of the turntable bearing is caused by heat treatment, the quenching layer is equivalent to the design thickness of the inner and outer circle. At this time, the material anti -tensile strength and the impact toughness value is small, resulting in a break, but this possibility accounted for a low proportion of the broken accident.

There are many reasons for the phenomenon of rotor bearing. When using an unspoken ring forged, the quality of the bearing material is unqualified. Bearing manufacturers, so that the material and design of the bearing can be guaranteed.
