Coupling function features and selection principles

　　Elastic sleeve pin couplings, plum-shaped elastic couplings, tire couplings, etc. are non-metallic elastic element flexible couplings. Their functions and characteristics in the transmission system are: connecting two shafts and transmitting torque Or movement, with different degrees of vibration reduction, cushioning and axial, radial and angular compensation functions.
　　Different types of couplings have different functions and characteristics in the transmission system. Transmission torque and movement are the main functions of the coupling, and the direction of rotation and the magnitude of the torque are not changed during the movement.
　　Gear couplings, universal couplings, chain couplings, slider couplings, etc. are flexible couplings with no elastic elements. Their functions and characteristics in the transmission system are: connecting two shafts, transferring rotation Moment or movement, with different degrees of axial, radial, and angular compensation functions at the same time.
　　The main features of elastic tube couplings, bellows couplings, film couplings, cross slider couplings, etc. are: connect two shafts, transmit motion, transmit small torque, and transmit motion with high precision, and No hysteresis.
　　Flange couplings, parallel shaft couplings, sleeve couplings, clamp couplings, etc. are rigid couplings. Their functions and characteristics in the transmission system are: connecting two shafts, transmitting torque or motion , No other functions.
　　Diaphragm couplings, serpentine spring couplings, etc. belong to flexible couplings with metal elastic elements. Their functions and characteristics in the transmission system are: connecting two shafts, transmitting torque or motion, and having different degrees of reduction Vibration, cushioning and axial, radial and angular compensation functions.
　　The main features of steel ball type, steel sand type, friction type, pin type, etc. couplings are: connecting two shafts, transmitting torque, overload protection, and flexible couplings have different degrees of compensation performance.
　　Selection principle of coupling:
　　Alignment: For good alignment, choose a rigid coupling, and when compensation is needed, choose a flexible coupling;
　　Assembly and disassembly: Considering the convenience of assembly and disassembly, choose a coupling that can directly move radially;
　　Environment: If working at high temperatures, couplings with non-metallic components are not available;
　　Cost: Under the same conditions, try to choose a coupling with a low price and simple maintenance.
