　　The assembly of the diaphragm coupling on the shaft is one of the keys to the installation of the coupling.The fit between the diaphragm coupling and the shaft is mostly interference fit. The connection is divided into keyed and non-keyed connections. The shaft hole of the elastic diaphragm coupling is divided into two types: cylindrical shaft hole and tapered shaft hole. ...

　　In practical applications, the intermediate shaft type is generally used, which is also called a double diaphragm coupling to improve the performance of two-axis offset compensation.The bolt is one of the important parts of the double diaphragm coupling. Its correct installation directly affects the performance life and safety of the diaphragm coupling...

　　Definition: No. 45 steel is a high-quality carbon structural steel with a carbon content of 0.42~0.50%, and 45 is the intermediate value. No. 45 steel is a high-quality carbon structural steel with low hardness and easy cutting processing. It is a common material for shaft parts. After quenching and tempering (or normalizing), better cutting...

　　The coupling is selected according to the load conditions, calculated torque, shaft end diameter and working speed and other factors.The torque is calculated as follows: TC=KT=K9550 PW/n＜Tn where Tc—calculated torque (N•m)...

　　Two commonly used measurement and adjustment methods in the process of repairing couplings can be divided into different measurement tools: 1) Using a knife-shaped ruler and a feeler gauge to measure the misalignment of the coupling and using a wedge-shaped clearance rail or a feeler gauge to measure the coupling The non-parallelism of the end face of the device, this method is suitable...

　　Gear coupling is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth.The external teeth are divided into two types of tooth shapes: straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis, and the tooth side clearance is more than that of ordinary teeth...

　　Nylon, Chinese polyamide, English name Polyamide (PA), is the general term for thermoplastic resins containing heavy amide groups-(NGCO)-on the molecular backbone.The name is determined by the specific number of carbon atoms of the synthesized monomer.Nylon rods have good toughness and wear...

　　The maximum torque transmitted by the coupling should be less than the allowable torque value. The determination of the maximum torque should consider the acceleration/deceleration torque and overload torque required for machine braking. However, when the design data is insufficient or the analysis is difficult, the maximum torque can be determined by Calculating torque selection...

　　Parallel deviation; when the two shafts are connected, the deviation between the two shafts in the radial direction.Angle deviation: When the two shafts are connected, the deviation angle of the two shafts.Axial deviation: when the two shafts are connected, the displacement of the two shafts in the axial direction. ...

　　The main structure of the serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and a serpentine spring sheet.It transfers torque by embedding the serpentine spring into the tooth slots of the two halves of the coupling. For example, the coupling uses serpentine springs to embed the two half of the coupling...
