Product Description
Problems needing attention in metallographic analysis of bearing materials
(1) Multi-scale structure of bearing materials: atomic and molecular level, dislocation and other crystal defect level, grain microstructure level, meso-structure level, macro-structure level, etc.
(2) The inhomogeneity of the microstructure of the turntable bearing material: the actual microstructure often has the inhomogeneity of geometric morphology, chemical composition and micro-performance (such as microhardness and local electrochemical degree);
(3) The directionality of bearing materials' microstructure: including anisotropy of grain morphology, directionality of macrostructure, crystallographic selection orientation, directionality of macroscopic properties of materials, etc., which should be analyzed and characterized respectively;
(4) The variability of bearing materials' microstructure: chemical composition changes, phase transition and microstructure evolution caused by external factors and time changes, etc. may all lead to the changes of materials' microstructure. Therefore, besides the qualitative and quantitative analysis of static microstructure, bearings should pay attention to whether it is necessary to study the solid phase transition process, microstructure evolution dynamics and evolution mechanism.
The above slewing bearing can also be divided into three different types.
#1 Slewing bearing with no gear
#2 Slewing bearing with external gear
#3 Slewing bearing with internal gear
Turntable bearing is the most basic and standard mechanical part in mechanical manufacturing technology, and it is also the most widely used coupling and rotating technology in mechanical industry. It has the advantages of simple structure, reliable quality, high precision, convenient assembly, easy disassembly and assembly of parts, good reusability and so on. Bearing parts are connected by bolts, that is, two connected bodies are closely attached and have enough axial pre-tightening force (i.e. axial tensile stress) by the torque exerted by "tightening", so as to ensure the reliable connection and normal operation of the connected parts. When assembling, the clamping force must be large enough to ensure that the connected parts do not move relative to each other during the working process. In addition, the applied clamping force must ensure that the bolts and connected parts will not be damaged or plastically deformed during assembly and service.

detailed product parameters
RKS.061.20.0944 bearing basic introduction: 1. the standard of this bearing is slightly different from the number of each brand, which belongs to the external tooth type four-point contact ball rotary support turntable bearing. the material is usually determined according to the customer host, and the material is different in different use occasions. generally, 50Mn or 42CrMo carbon steel or bearing steel is used. The quenching hardness can reach HRC58-64, and the quenching and tempering hardness is 229-269HB, which can ensure the bearing life and rotation accuracy. 2. The bearing has a thickness of 56mm, an outer diameter of 1046.7mm, an inner diameter of 872mm, and a thickness of 56 mm. It is a medium-sized or large-sized bearing with a weight of 77kg. It is a bearing with a large market manufactured by LYDZC according to domestic and foreign standards. 3. RKS.061.20.0944 model bearings produced by LYDZC are in the range of P4A (UP)-P5, which are mostly used as main engine accessories with large bearing requirements, and can ensure the main engine to show good operation. 4. The rolling bodies adopt steel balls and balls, and there is no cage or isolation block between the rolling bodies, which increases the load of the bearing and makes the bearing run more smoothly. 5. The bearings are positioned by inner and outer ring mounting holes, which is convenient for installation and disassembly.

LYDZ turntable bearing is a kind of large bearing with special structure, which can bear large axial load, radial load and overturning moment at the same time, and has many functions such as support, rotation, transmission and fixing. Under normal circumstances, turntable bearings are equipped with mounting holes, lubricating oil and sealing devices, which can meet the different needs of various hosts working under different working conditions; On the other hand, the turntable bearing itself has the characteristics of compact structure, convenient guiding rotation, simple installation and easy maintenance, etc., and is widely used in large-scale rotating devices such as hoisting and transportation machinery, mining machines, construction engineering machinery, port machinery, wind power generation, medical equipment, radar and missile launcher. The single-row four-point contact ball-type turntable bearing is composed of two races, which is compact in structure and light in weight. The steel balls are in four-point contact with the arc raceway, and can bear axial force, radial force and tilting moment at the same time. Rotary conveyors, welding operators, small and medium-sized cranes, excavators and other construction machinery can be selected.
