Forging

Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Forging can eliminate the defects such as loose casting in the smelting process and optimize the microstructure. At the same time, due to the preservation of the complete metal flow line, the mechanical properties of forgings are generally better than castings of the same material. Related machinery in high load, severe working conditions of important parts, in addition to the shape of a relatively simple available rolling plates, profiles or weldments, the use of forgings.

Forging is an important metal product, which is formed by processing metal at high temperature. Forgings have the advantages of high strength, high hardness and good plasticity, and are widely used in machinery and equipment, automobile industry, aerospace and other fields. In the forging process, the yield strength of forgings is an important indicator, which is the ability of forgings to undergo plastic deformation under load.

Bearing

Investigate its role should be to support, that is, the literal interpretation used to bear the shaft, but this is only part of its role, the essence of the support is to be able to bear the radial load. It can also be understood that it is used to fix the shaft. Bearing fast and easy automatic selection is included. Is to fix the shaft so that it can only achieve rotation, and control its axial and radial movement. The motor can't work without bearings. Because the shaft may move in any direction, the shaft can only be rotated when the motor is working. Theoretically speaking, it is impossible to realize the function of transmission. Not only that, the bearing will also affect the transmission. In order to reduce this influence, good lubrication must be realized on the bearing of the high-speed shaft. Some bearings already have lubrication, which is called pre-lubricated bearings. Most bearings must have lubricating oil, which is responsible for not only increasing energy consumption but also easily damaging the bearings due to friction during high-speed operation. The idea of turning sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.

Alloy Steel

Alloy steel alloy steel in addition to iron, carbon, add other alloy elements, called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different elements added and the appropriate processing technology, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties can be obtained.

Large ring

Large rings are key forgings for aero-engines. The large ring formed by rolling technology has the advantages of compact structure, high strength and good toughness, which can not be replaced by casting or other manufacturing technology. The performance and quality of ring forgings determine the performance and behavior of key aviation parts to a large extent. The structure and performance of large rings are often directly related to the service life and reliability of the aircraft. Whether the ring forging is integral, high quality and high precision has a significant impact on the economic bearing capacity of the aircraft and the aero engine. Therefore, the production quality and manufacturing process of the special-shaped ring similar to the part type line have a very important influence on reducing the cost of engine development and improving the engine development and production capacity.

Gear ring

The ring gear is embedded on the outer edge of the flywheel after heating, and fastened to the outer edge of the flywheel after cooling to mesh with the starter gear to drive the crankshaft to rotate and start the engine.
