Description

Technical Field

[0001] The utility model belongs to the technical field of generators, and more specifically, particularly relates to a generator housing central axis reinforcement device. Background Art

[0002] Generator refers to a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. Generators come in many forms, but their working principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that are electromagnetically inductive with each other to generate electromagnetic power and achieve the purpose of energy conversion.

[0003] Most existing generators have a reinforced casing at the center axis. Since the center axis of the generator is connected to the equipment, the purpose of providing the reinforced casing is to protect the center axis when the generator generates vibration during operation, to prevent the center axis from being affected by the vibration and causing irreversible deformation or looseness at the connection with the equipment, thereby affecting the service life of the center axis. However, most existing center axis reinforcement devices are fixedly mounted on the outer wall of the center axis. Although they can well protect the center axis and prevent it from deformation, during long-term use, since the position of the center axis reinforcement device on the outer wall of the center axis is fixed, the center axis is still affected by vibration, and its outer wall will be worn. If the center axis is not repaired in time, it is very easy to cause the center axis to be deformed and damaged by the vibration, and even affect the connected equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a generator casing central axis reinforcement device is provided, in order to achieve a more practical purpose. Utility Model Content
