Stainless steel rigid coupling accessories
A stainless steel rigid coupling is a mechanical component used to connect two shafts so that they rotate together and transmit torque. It mainly consists of two half couplings and connecting bolts. The two half couplings are usually disc-shaped structures that are installed at the ends of the two shafts that need to be connected. The connecting bolts are used to secure the two coupling halves tightly together to ensure that the two shafts rotate synchronously during rotation.
Material Properties - Stainless Steel
Corrosion resistance: Rigid couplings made of stainless steel (such as 304 stainless steel, 316 stainless steel) have good corrosion resistance. In some working environments with humid or corrosive media, such as in food processing, chemical production and other industries, stainless steel can prevent couplings from being damaged due to rust. For example, in conveying equipment in the food and beverage industry, stainless steel rigid couplings can resist corrosion from juice, milk and other liquids, ensuring long-term stable operation of the equipment.
Mechanical properties: Stainless steel has high strength and hardness, which allows rigid couplings to withstand large torques. Its tensile strength and yield strength can meet the requirements for use in various mechanical transmission systems. At the same time, stainless steel also has good toughness. When subjected to a certain impact or overload, the coupling will not break easily, ensuring the safety of the transmission.
Working principle
When the driving shaft rotates, the torque is transmitted to the driven shaft through the connecting bolt between the half couplings, causing the two shafts to rotate synchronously. Since a rigid coupling has no elastic elements and is a rigid connection, the angular velocities of the two shafts during rotation are exactly the same. This requires that the two connected shafts have good alignment, otherwise additional stress will be generated due to misalignment of the shafts, resulting in damage to the coupling, shaft or other transmission components.
Performance characteristics
High transmission efficiency: The torque transmission efficiency of the stainless steel rigid coupling is very high because it is a direct rigid connection with almost no energy loss in elastic deformation or relative sliding. In some mechanical systems that require high power transmission efficiency, such as the spindle transmission system of precision machine tools, it can meet the requirements well.
Simple and compact structure: Its structure is relatively simple, mainly consisting of two half couplings and connecting bolts, without complex elastic elements or other ancillary structures. This simple structure makes it easier to install and maintain, and takes up less space, making it suitable for use in mechanical devices with limited space.
Machine tool industry: In precision machine tools, such as lathes, milling machines, grinders, etc., stainless steel rigid couplings are used to connect the motor shaft and machine tool spindle to ensure high-precision power transmission. Since machine tools require precise motion control when working, rigid couplings can ensure that the power of the motor is accurately transmitted to the spindle, thereby achieving high-precision machining.
Food and pharmaceutical industries: Because these industries have high hygiene requirements for equipment, stainless steel rigid couplings can be used to connect the transmission shafts of various conveying equipment, mixing equipment, etc. Its corrosion resistance can prevent equipment from being contaminated, and its reliable transmission performance can ensure the normal production process.
Chemical and petroleum industries: In chemical and petroleum production equipment, as long as the medium does not severely corrode stainless steel, rigid couplings can be used to connect the shafts of pumps, compressors and other equipment. It can withstand large torque and meet the power transmission requirements of these equipment under high load operation.
