Technical Field

[0002] The back pulley, also known as the coupling, is an important component in mechanical transmission, mainly used to connect the rotor of the steam turbine to the generator. Its main function is to transmit the torque of the steam turbine to the generator, so that the generator rotor can rotate at high speed to generate electricity. There are many structural types of back pulleys, including rigid, flexible and semi-flexible couplings, each type has its specific uses and advantages. For example, the rigid coupling has a simple structure, can bear the weight distributed from the adjacent rotor, reduce the number of support bearings and shorten the length of the unit; while the flexible coupling does not transmit axial thrust, basically does not transmit vibration, has low alignment requirements, but is easy to wear, requires lubrication, and has a high cost. These different types of couplings are selected according to specific application scenarios and needs to ensure the efficiency and stability of the gas generator.
