The features of slewing bearing.

Slewing bearing is a new type of mechanical component, which consists of inner and outer rings and rolling bodies, etc.  Slewing bearing is a large bearing capable of bearing comprehensive loads and bearing large axial, radial loads and overturning moments at the same time. This article mainly introduces the features of slewing bearing. 

Here are the main points of the article:

1.A brief introduction to slewing bearing

Slewing bearing is a new type of mechanical parts that has gradually emerged in the world in the past 40 years.  It consists of internal and external circles and rolling bodies, etc.  The slewing bearing that has been shaped for production in China mainly refers to the design and manufacturing technology of the former federal republic of Germany Rothe Erde company, which was organized by tianjin engineering machinery research institute designated by the ministry of machinery industry in the early 1980s. Released on December 20, 1984 of the People's Republic of China machinery industry standard: JB / 2300-84 the slewing bearing type, basic parameters and technical requirements, composed mainly of machinery and electronics industry of tianjin engineering machinery research institute,  slewing bearing factory is responsible for drafting, the country then issued standard of construction machinery in 1991: JB36. 1-36. 3-91, released in 1999 and 2011 successively new machinery industry standard JB / 2300-1999 and JB / 2300-2011. 

Slewing bearing is a large bearing capable of bearing comprehensive loads and bearing large axial, radial loads and overturning moments at the same time. Slewing bearing bearing bearing is generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, thus enabling the design of the main engine to be compact, easy to guide and easy to maintain. Slewing bearing bearing presence of tooth, tooth and tooth in the four-point contact ball bearing, double row angular contact ball bearing, crossed cylindrical roller bearing, crossed tapered roller bearing and three composite bearings, four row cylindrical roller series, including four-point contact ball bearing has high static load capacity, crossed cylindrical roller with high load capacity, preloaded can make crossed tapered roller bearing of the bearing has great support stiffness and the rotation accuracy, three rows of cylindrical roller bearing combination height because of the increase to the bearing capacity of bearing, all kinds of power respectively by different race to bear, so under the same stress distribution,The bearing diameter can be greatly reduced, thus making the main engine more compact and characterized by a high-bearing slewing bearing bearing. Slewing bearing is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and equipment, as well as high-precision radar machinery and missile launchers and other equipment of large slewing devices. At the same time, it is also possible to design, develop and produce various special structural slewing bearing bearings according to users' specific requirements. 

2. The features of slewing bearing:

In many large engineering construction process are used to slewing bearing, its product characteristic is obvious, mainly driven by rotary, mounting holes, lubricating oil, and sealing device, often plays an important role in the real industrial production, especially of truck crane, rail crane, port crane equipment, can withstand the axial force and radial force and overturning moment. slewing bearing, also known as the joint of the machine, can be used in excavators, filling machines, radar antenna mounts and other mechanical equipment. 

You will find that the slewing bearing the characteristics of the obvious, is one of the many important components of machinery and equipment, general in dynamic compaction machine, drilling machine, boring machine, and crane, excavator plays an important role in equipment, slewing bearing bearing the characteristics of the obvious, the applicable scope is broad, in the midst of a lot of large mechanical equipment can rotate 360 degrees, particularly large in diameter, is mainly by connecting bolts, rather than rely on tight fit. 

So what does slewing bearing tell you about?In general, there are many components of slewing bearing.  The whole slewing bearing is divided into outer ring, sealing belt and rolling body from left to right.  In general, slewing bearing plays a large role in the implementation of the rotation, and the rotation of the entire equipment, whether 360° or 120° in the designated area, can be easily realized. In addition, slewing bearing is widely used in excavators, filling machines, wheeled cranes, crawler cranes and other equipment.
