1. Adaptation type of couplings Couplings are partly standardized products. In the initial stage of choosing couplings, you can understand whether there are any coupling products that meet the requirements of use in the national standards, machinery industry standards and national patents. type.If the coupling cannot find the matching type, you can contact the manufacturer to design the coupling product by yourself. 2. Variety and type of coupling The selection of the variety and type of coupling is determined based on the comprehensive functions of the coupling in the transmission system, and the overall design of the transmission system, such as the type of prime mover and the working load. The type, the speed of the prime mover, the transmission accuracy, the shaft offset, the state of the working environment, etc., are the main reference basis for the selection of the coupling. 3. The torque of the coupling and the torque of the primary coupling should meet the requirements of the power machine of the transmission system. According to the power and speed of the power machine and working machine, a reasonable torque value of the coupling can be calculated. Preliminary selection of couplings. 4. Coupling model adjustment After the initial selection of the coupling, the size of the coupling should be determined according to the shaft diameter and the length of the shaft hole of the driving shaft and the driven shaft, and the specifications of the coupling should be adjusted.The adjustment of the coupling model should also consider whether the rotation speed between the driving shaft and the driven shaft connected by the coupling is constant and whether the shaft diameter is the same. 5. The coupling form of the coupling The coupling form of the coupling is determined by the connection form of the driving shaft and the driven shaft, and the most commonly used connection method is the key connection. 6. The final selection of the coupling. In the final selection of the coupling, various factors must be considered again to ensure that the size, torque, shaft diameter, and shaft hole of the coupling are matched with the prime mover and working machine. Can adapt to the working environment.After the coupling model is selected, check the strength of the key and finally determine the coupling model.When the shaft and the shaft are to be connected to transmit power, a belt pulley or gear is generally used for the connection, but if the two shafts are required to be in a straight line and require constant speed rotation, a coupling must be used to connect.However, due to machining accuracy, thermal expansion of the shaft or bending of the shaft during operation, the concentricity between the two shafts will change. Therefore, the flexible coupling can be used as a bridge to maintain the power transmission between the two shafts and achieve absorption. The radial, angular and axial deviations between the two shafts extend the life of the machine and improve the quality of the machine.
