Power generating device

Abstract

The invention discloses a power generating device. The power generating device comprises an engine and a generator. An output shaft of the engine is connected with a rotor shaft of the generator through a flexible coupling. The generator comprises the rotor shaft, iron cores and permanent magnets. The iron cores are composed of multiple stampings in an overlapping mode. An axle hole and mounting holes of the permanent magnets are arranged in the central sections of the stampings. The permanent magnets can be directly inserted into the iron cores on the rotor shaft composed of the stampings and therefore the quick and convenient installation can be achieved. More of the corner magnetic line of force of the permanent magnets can pass through the iron cores in a more even manner through communicated grooves. The boundary lines of the adjacent magnetic fields can be made clearer due to heat emission holes and concave grooves. A better linear distribution of the magnetic fields can be achieved, harmonic waves losess can be reduced and the working efficiency of the engine can be improved. Meanwhile, self-adaptive adjustment is achieved by flexible transmission ring segments and the flexible transmission ring segments are capable of compensating the errors in manufacturing, assembling and transmitting. The transmission vibration is low and the adaptability is high. At the same time, the manufacturing precision and the assembling difficulty are lowered, the working efficiency in assembling the power generating device is improved and the damage, caused by assembling errors, to the engine and an electric motor is avoided.

Description

technical field [0001] The invention relates to a power generating equipment, in particular to a combined power generating device. Background technique [0002] The combined power generation device is composed of two parts, the engine and the generator. The generator is composed of a rotor and a stator, and the rotor includes components such as a rotor shaft, an iron core, and a magnetic pole. The iron core of the rotor is generally composed of overlapping punched sheets of high magnetic permeability materials. The structure of the punched sheets directly affects the efficiency, life, performance, and assembly and production efficiency of the generator. [0003] For example, the existing power generator with a power of 6Kw adopts a magnetic tile structure for its power generation device. During installation, the magnetic tile is fixed on the cylindrical iron core composed of punched pieces through screws. The installation takes a long time and the work efficiency is low. At...
