Description

Speed reducer of wind driven generator
Technical Field
The invention relates to the technical field of wind driven generators, in particular to a speed reducer of a wind driven generator.
Background
The generator is a power generation device, and the wind power generator is a power device for converting wind energy into mechanical work, the mechanical work drives a rotor to rotate, and finally, alternating current is output. The wind driven generator generally comprises wind wheels, a generator (comprising a device), a direction regulator (tail wing), a tower, a speed limiting safety mechanism, an energy storage device and the like. The working principle of the wind driven generator is simple, the wind wheel rotates under the action of wind force, the kinetic energy of wind is converted into mechanical energy of the wind wheel shaft, and the generator rotates to generate electricity under the drive of the wind wheel shaft. In a broad sense, wind energy is also solar energy, so it can be said that a wind power generator is a heat energy utilization generator using the sun as a heat source and using the atmosphere as a working medium.
The wind driven generator consists of a machine head, a rotating body, a tail wing and blades. Each part is important, and functions of each part are as follows: the blades are used for receiving wind power and converting the wind power into electric energy through the machine head; the tail wing enables the blade to always face the direction of the incoming wind so as to obtain the maximum wind energy; the rotating body can enable the machine head to flexibly rotate so as to realize the function of adjusting the direction of the tail wing; the rotor of the machine head is a permanent magnet, and the stator winding cuts magnetic force lines to generate electric energy.
At present, when the wind driven generator is in a working state, the blades rotate faster and faster along with the increase of wind speed, the windward side of the blades is unstable easily when the rotation speed of the blades is overlarge, and the blades are broken off due to vibration of a machine body and overlarge centrifugal force, so that potential safety hazards are brought. When the rotating speed of the wind power generator shaft is too high, the electronic components are easy to burn out due to the fact that the wind power generator shaft is too high, so that effective deceleration braking measures are needed to be adopted to ensure that the wind power generator can still work normally under the condition of strong wind, and the wind energy utilization rate is improved.
The speed reduction method of the existing wind driven generator speed reduction device achieves the purpose of speed reduction and braking by applying resistance on one side of the transmission rotating shaft, the speed reduction mode is single, the resistance distribution borne by the transmission rotating shaft is uneven, the speed reduction effect is poor, the normal operation of the wind driven generator can be influenced when the speed reduction effect is serious, the existing speed reduction device lacks a heat dissipation mechanism, heat generated during speed reduction cannot be rapidly dissipated, speed reduction failure accidents are easy to occur, the service life of the wind driven generator is shortened, and the practicability is low.
