Horizontal-axis wind turbine generator system spindle with vibration damping function

Abstract

The present invention discloses a horizontal-axis wind turbine generator system spindle with a vibration damping function. The horizontal-axis wind turbine generator system spindle includes a fixed tower, a supporting plate is fixedly connected to the inner side wall of the fixed tower, a damping rod is fixedly connected to the outer side wall of the supporting plate, a sleeve is fixedly connected to the tail end of the damping rod, a spindle is rotatably connected to the inner side wall of the sleeve, an inner bearing is fixedly connected to the outer side wall of the spindle, an outer bearing is rotatably connected to the outer side wall of the inner bearing, sealing blocks are symmetrically and fixedly connected to the outer side wall of the outer bearing, a lubricating box is fixedly connected to the inner side wall of the fixed tower, and a lubricating mechanism is slidably connected to the inner side wall of the lubricating box. By using the spindle, a downward moving distance of the sleeve may be increased, so that more lubricating oil can be conveyed between the outer bearing and the inner bearing, meanwhile, more gases can be compressed between the spindle and each sealing block, so that a high-pressure state between the spindle and each sealing block is kept.

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a main shaft of a horizontal axis wind turbine with its own vibration reduction and damping. 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. Wind turbines are generally composed of components such as wind rotors, generators (including devices), steering devices (tail fins), towers, speed-limiting safety mechanisms, and energy storage devices. [0003] 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 ge...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem in the prior art that the lubricating oil inside the bearing leaks during long-term work, which leads to the reduction of the service life of the main shaft and the bearing, and proposes a main shaft of a horizontal axis wind turbine with its own vibration reduction and damping
