   PinCouplingClassification characteristics

  Due to manufacturing and installation errors, deformation after load, and the influence of temperature changes on the two shafts connected by the coupling, the relative position of the two shafts will change, and strict alignment is often not guaranteed.According to whether the coupling has elastic elements, whether it has the ability to compensate various relative displacements, that is, whether the coupling function can be maintained under the premise of relative displacement, and the purpose of the coupling, couplings can be divided into rigid couplings, Flexible couplings and couplings.The main types and characteristics of the coupling and the remarks on the role of the type in the transmission system.

  Flexible couplings Flexible couplings without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation functions including gear couplings and universal couplings , Chain coupling, slider coupling, etc.The flexible coupling with elastic elements can transmit motion and torque; it has different degrees of axial, radial, and angular compensation functions; it also has different degrees of vibration reduction and buffering to improve the working performance of the transmission system. Including various non-metal elastic element flexible couplings and metal elastic element flexible couplings, variousFlexible couplingThe structure is different, the difference is big, and the role in the transmission system is also different.

  Rigid couplings can only transmit motion and torque. There are several failures of drum gear couplings and their causes. It does not have other functions including flange couplings, sleeve couplings, and clamp couplings. Etc., the calculation of the coupling and the role of the two types.
