Product Description
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Can Stainless Steel Couplings Withstand High Torque and Heavy Loads?
Yes, stainless steel couplings are designed to withstand high torque and heavy loads in various industrial applications. Stainless steel is known for its excellent mechanical properties, including high strength and durability, making it well-suited for coupling systems that experience significant loads.
Stainless steel couplings are available in different designs, such as rigid couplings, flexible couplings, and beam couplings, each offering specific benefits in terms of torque transmission and load-carrying capacity.
Rigid Stainless Steel Couplings: Rigid couplings provide a solid connection between shafts and are ideal for applications where precise shaft alignment and torque transmission are crucial. They can handle high torque and heavy loads without any noticeable deformation or backlash. Rigid couplings are commonly used in machinery that requires precise motion control and accurate synchronization.
Flexible Stainless Steel Couplings: Flexible couplings, also known as misalignment couplings, can accommodate some degree of shaft misalignment while transmitting torque and handling heavy loads. They are designed to maintain a constant velocity ratio even in situations where shafts are not perfectly aligned. Flexible stainless steel couplings can help reduce stress on bearings and other components by compensating for misalignments and dampening vibrations, making them suitable for various industrial machinery and power transmission systems.
Beam Stainless Steel Couplings: Beam couplings are a type of flexible coupling that uses a helical cut in a stainless steel beam to provide flexibility. They are capable of handling high torque and moderate misalignments while maintaining a compact design. Beam couplings are commonly used in motion control systems, encoders, and other precision equipment that requires torque transmission with minimal backlash.
The load-carrying capacity and torque handling capability of stainless steel couplings depend not only on the design but also on the specific grade and size of the coupling. When selecting a stainless steel coupling for high torque and heavy load applications, it’s essential to consider factors such as the operating environment, shaft sizes, misalignment requirements, and overall system specifications.
In summary, stainless steel couplings are well-suited for applications that require withstanding high torque and heavy loads. Proper selection and installation of the appropriate coupling type and size will ensure optimal performance and reliability in demanding industrial settings.
Stainless Steel Couplings in Food Processing and Medical Equipment
