Speed reduction device for wind driven generator

Abstract

The invention discloses a speed reduction device for a wind driven generator, and relates to the technical field of speed reduction devices. The problems that when an existing speed reduction device for wind power generation is used for speed reduction, a rotating shaft is prone to inclining towards one side, resistance borne by a transmission rotating shaft is not evenly distributed, and the speed reduction effect is poor are solved. The speed reduction device for the wind driven generator comprises a speed reduction mechanism, wherein the speed reduction mechanism is composed of a speed reduction shell, an electric push rod, an upper speed reduction strip, a lower speed reduction strip and speed reduction discs. When the device is used for speed reduction of the transmission rotating shaft, the upper speed reduction strip and the lower speed reduction strip can move oppositely at the same time, and therefore the transmission rotating shaft is subjected to speed reduction through theupper speed reduction disc and the lower speed reduction disc, the transmission rotating shaft is evenly stressed, the speed reduction effect is good, and the phenomena of deformation and inclining are avoided; and through anti-skid lines of a shaft body of the transmission rotating shaft, the friction force between the transmission rotating shaft and the speed reduction discs can be increased, the speed reduction effect is better, and the practicability and stability of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of deceleration devices, and more specifically relates to a deceleration device for wind power generators. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind generator is a thermal energy utilization generator that uses the sun as a heat source and the atmosphere as a working medium. [0003] At present, when the wind turbine is in working condition, as the wind speed increases, the blades w...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a deceleration device for wind power generators to solve the problem that the existing deceleration device for wind power generation only applies resistance to one side of the transmission shaft to achieve the purpose of braking during deceleration, which is easy to make The shaft is skewed to one side, the resistance on the transmission shaft is distributed unevenly, and the deceleration effect is poor. In severe cases, it will affect the normal operation of the wind power generation device. The existing deceleration device does not have a heat dissipation mechanism, which cannot dissipate the heat generated during deceleration in time. , it is easy to cause the phenomenon of deceleration failure, and the problem of low practicability
