The initially selected coupling size, that is, the diameter of the shaft hole d and the length of the shaft hole L, should meet the requirements of the shaft diameter of the driving and driven ends, otherwise the specifications of the coupling should be adjusted according to the shaft diameter d.It is a common phenomenon that the shaft diameters of the main and driven ends are different. When the torque and speed are the same, and the shaft diameters of the main and driven ends are different, the coupling model should be selected according to the larger shaft diameter.In the newly designed transmission system, the seven shaft hole types specified in GB/T3852 should be selected, and the J1 shaft hole type is recommended to improve versatility and interchangeability. The length of the shaft hole is in accordance with the coupling product standard. .
Understand the comprehensive functions of the coupling (especially the flexible coupling) in the transmission system, and choose the type and type of the coupling from the overall design of the transmission system.According to the prime mover category and working load category, working speed, transmission accuracy, two-axis offset conditions, temperature, humidity, working environment and other comprehensive factors to select the type of coupling.Select the structure of the coupling according to the needs of the supporting host. When the coupling is used in conjunction with the brake, the coupling with brake wheel or brake disc should be selected; when overload protection is required, a safety coupling should be selected ; When connecting with flanges, the flange type should be selected; for long-distance transmission, when the axial size of the connection is large, it is advisable to choose the intermediate shaft type or the intermediate sleeve type.
