The common structural forms of slewing bearings are single-row, double-row four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, crossed cylindrical roller and crossed tapered roller slewing bearings, three-row cylindrical roller slewing bearings, balls Different structural forms such as column hybrid slewing bearing. Although the structure is different, the materials used are […]
In recent years, industrial robots have ushered in explosive development, especially due to the increase in labor costs, making manufacturing companies increasingly favor the use of more mechanized, more efficient, and lower-cost robots. When it comes to robots, we have to mention one of the important components, the reducer, which is what we often call […]
The life of the slewing ring raceway is determined by the quality of its own products and subsequent maintenance. It is even considered “three-point quality and seven-point maintenance”. The following phenomena generally occur after the raceway is damaged and failed: large gaps, oil leakage, jamming, abnormal noise, iron powder and even iron pieces on the […]
After the slewing ring is used for a period of time, spots or discoloration will be found on the surface, which not only affects the territory and smoothness of the bearing surface, but also directly affects the use effect and service life of the bearing. So, how to improve the brightness of the slewing bearing […]
Slewing bearing can also be called turntable bearing and rotating bearing. It is one of the important parts of modern construction machinery slewing devices, such as excavators, cranes, pile drivers, graders, road rollers, dynamic compactors, roadheaders, tower cranes, etc. Slewing bearings are always used. Due to the large load during operation and the harsh working […]
There are many technical indicators that reflect the accuracy of slewing bearings and slewing bearings, such as axial clearance and radial clearance, end jump and radial jump, parallel difference and inside and outside difference, roughness, dimensional tolerance, position tolerance, etc. So, do you know what the tolerance of slewing ring refers to? The dimensional accuracy […]
Recently, our company has produced a set of non-standard customized special-shaped high-precision slewing bearings for a high-tech enterprise in Beijing. This set of bearings is used on high-end automatic welding equipment for processing nuclear equipment. This is the second time this company has been with us. The first cooperation was for large-scale precision slewing bearings. […]
As a process to be realized by precision products, the situation of grinding teeth needs to be noted, and what kind of technical indicators should be achieved. This article analyzes one by one. Regarding the slewing bearing or slewing bearing, whether external or internal teeth, helical teeth, etc., the normal process level, there are gear […]
The slewing bearing is responsible for the operation and rotation of marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, and industrial machinery and equipment. It is an important transmission component necessary for machinery that needs to bear axial force, radial force, and tipping moment. . Therefore, the consideration of performance guarantee in […]
For equipment installed with slewing bearings, corresponding performance is the focus of users’ attention, and often requires high accuracy. In the application of equipment, the stability of the slewing bearing can meet the requirements of the special work nature of construction equipment, including bearing large axial load, radial load and overturning moment and other comprehensive […]
