1. Coupling function

Used to connect two shafts together, the two shafts cannot be separated during machine operation. Only when the machine is stopped and the connection is disconnected, can the two shafts be separated.

2couplingType of

The two shafts connected by the coupling may experience changes in their relative positions due to manufacturing and installation errors, deformation after loading, and temperature fluctuations, which often cannot guarantee strict alignment. according tocouplingCouplings can be divided into rigid couplings, flexible couplings, and safety couplings based on whether they have elastic elements, whether they have the ability to compensate for various relative displacements, whether they can maintain their connection function under relative displacement conditions, and the purpose of the coupling.couplingMain types, characteristics, and their roles in transmission systems

Rigid couplings can only transmit motion and torque, and do not have other functions such as flange couplings, sleeve couplings, clamp couplings, etc
Flexible couplings without elastic components not only transmit motion and torque, but also have varying degrees of axial, radial, and angular compensation performance, including gear couplings, universal couplings, chain couplings, slider couplings, etc

Flexible couplings with elastic elements capable of transmitting motion and torque; Has varying degrees of axial, radial, and angular compensation performance; It also has varying degrees of vibration reduction and buffering effects, improving the working performance of the transmission system, including various non-metallic elastic element flexible couplings and metal elastic element flexible couplings. The structures of various elastic couplings are different, and their roles in the transmission system are also different

The safety coupling transmits motion and torque, and provides overload safety protection. Flexible safety couplings also have varying degrees of compensation performance, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type and other safety couplings

Electric hoist, abbreviated as electric hoist. It consists of an electric motor, a transmission mechanism, and a drum or sprocket, and is divided into two types: wire rope electric hoist and loop chain electric hoist. Usually using a built-in brake Most electric hoists are operated by humans using buttons on the ground, and can also be operated from the cab or remotely controlled using wired (wireless) technology. The main structure includes a reducer, a running mechanism, a drum device, a hook device, a coupling, a soft cable current inlet, a limiter, and a conical rotor motor that integrates power and braking force. It has the characteristics of small size, light weight, easy operation, and convenient use.
