Non-standard alloy steel large diameter Shaft coupling

Overview of Shaft coupling          

Coupling is a key component in the mechanical transmission system, mainly used to connect two rotating axes, so that they rotate in sync and transmit torque and movement. Its importance lies in its ability to compensate for misalignment errors between the two axes and reduce mechanical failures caused by factors such as installation, lack of manufacturing accuracy or thermal expansion during operation. In addition, the coupling can absorb vibration and shock, reduce the noise and wear of the mechanical system, and improve the working efficiency and service life of the machine. In practical applications, choosing the right coupling type is crucial to ensure the stability and reliability of the mechanical system, and different working conditions require different types of couplings to meet specific needs. Through its functions such as cushioning and damping, couplings are also of great importance for the protection of expensive mechanical equipment.

Production process of Shaft coupling

Casting

Casting blank production is the basis of the entire production process, mainly including mold making, melting and pouring steps. First of all, according to the design drawings, high-precision mold is made to ensure that the casting size is accurate. A suitable material (such as cast iron or cast steel) is then selected and heated to a liquid state in an electric furnace or cupola. After reaching the appropriate temperature, the melted metal is slowly poured into the preheated sand mold through the gate to ensure that the filling is complete and there is no air hole. After cooling and solidification, open the mold and take out the preliminary forming of the coupling blank.

Rough Machining

Roughing is designed to remove excess material from the surface of the blank, bringing it closer to the final size. This stage usually uses lathes, milling machines and other equipment to process the basic shape of the coupling, such as cutting the outer circle, end face and plane. During the roughing process, a certain margin should be reserved for subsequent finishing, and attention should be paid to avoid excessive stress concentration points.

Finishing Machining

Finishing is the fine finishing of the roughed parts to achieve the dimensional accuracy and surface finish required by the design. This step includes but is not limited to grinding, boring, drilling and other operations. Finishing not only requires strict control of dimensional tolerances, but also needs to pay special attention to form and position tolerances to ensure the accuracy of each matching part, so as to ensure the working performance of the coupling.

Heat treatment

Heat treatment is to improve the mechanical properties of the coupling, such as strength, hardness and wear resistance. Commonly used heat treatment methods are quenching, tempering, normalizing and so on. After proper heat treatment process, the internal structure of the material can be changed and its comprehensive mechanical properties can be improved. For different types of couplings, the appropriate heat treatment scheme should be selected according to the specific application needs.

Surface treatment

The purpose of surface treatment is to enhance the corrosion resistance, aesthetics and wear resistance of the coupling. Common surface treatment technologies include painting, galvanizing, phosphating and so on. In addition, special coating technologies can be used to meet the requirements of use in specific environments. After finishing the surface treatment, it is also necessary to carry out a comprehensive quality inspection, including dimensional inspection, appearance inspection and the necessary performance testing to ensure that every factory coupling meets the quality standards.

Package of Shaft coupling

Cleaning treatment to remove surface impurities, anti-rust treatment to prevent oxidation, the selection of appropriate packaging materials such as wooden boxes or cartons, and add anti-shock cushion protection, and finally identify product information and handling precautions to ensure transportation safety.
