Abstract

The invention provides an assembling type external shell used for a power generator. The external shell is formed by two symmetrical semicircular metal shells through splicing. The two side edges of each metal shell are provided with an adapter plate and a connecting plate. The surface of the connecting plate is provided with multiple sealing grooves which are internally provided with sealing rubber strips I protruding out of the sealing grooves so that the gap between the two connecting plates can be sealed by the sealing rubber strips I after the two metal shells are spliced and the two connecting plates are fixed through a fixing bolt. The external side of the adapter plate is connected with a rotating shaft in an adapter manner through a connecting member, and the surface along the length direction of the adapter plate is provided with a bar-shaped groove. The bar-shaped groove is internally provided with a compression spring so that the compression spring is enabled to be in the compression state and generate elastic force after the two metal shells are spliced and the two connecting plates are fixed through the fixing bolt, and separating of the two metal shells is facilitated. The external shell is manufactured in a manner of being formed by the two symmetrical semicircular metal shells through splicing so that the external shell is enabled to be openable, and maintenance work is facilitated.

Description

technical field [0001] The invention belongs to a generator in the field of mechanical physics, in particular to an assembled outer casing for a generator. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water 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. Converted to electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive materials to form magnetic circuits and ci...
