Between the power machine and the working time, the main and driven ends are connected by one or several different types or different types and sizes of couplings to form a shafting transmission system. In mechanical transmission, the power machine is nothing more than an electric motor, an internal combustion engine and a steam turbine. Due to the different working principle and structure of the power machine, its mechanical characteristics are very different, some operate smoothly, and some have impact during operation, which has an unequal impact on the transmission system.
The mechanical characteristics of the power machine have a certain impact on the entire transmission system. Due to the different mechanical characteristics of different types of power machines, the corresponding power factor KW should be selected to select the best coupling suitable for the system. The type of power machine is the basic factor for selecting the type of coupling; the power of the power machine is one of the main criteria for determining the size of the coupling, and is proportional to the torque of the coupling.
The power machines in the fixed mechanical product transmission system are mostly electric motors. The power machines in the mechanical product transmission system (such as the general ship, various vehicles, etc.) are mostly internal combustion engines. When the power machine is an internal combustion engine with different cylinder numbers, the torsional vibration must be considered. The influence of the transmission system is related to the number of cylinders of the internal combustion engine and whether the cylinders are working properly. At this time, a flexible coupling should be generally used to adjust the natural frequency of the shafting and reduce the torsional vibration amplitude, thereby damping, buffering, and protecting the transmission components, improving the alignment performance, and improving the stability of the output power.
