Wind-power generating variable-propeller speed reducer

Abstract

The invention relates to a wind-power generating variable-propeller speed reducer. Two-stage satellite transmission structures are arranged in a box and are connected with each other to be transmittedto output shafts in sequence; the sun gears of the first-stage satellite transmission structure are connected with a bevel gear through a bevel-gear connecting sleeve; the bevel gear is coaxial withthe all stages of sun gears and the output shafts; a shell which is arranged in the front of the box is connected with a motor flange; the motor is in interference fit connection with the shaft of thebevel gear through an input connection sleeve; the shaft of the bevel gear is meshed with the bevel gear; and the input connection sleeve and the bevel gear are arranged at an angle of 90 degrees. The variable-propeller speed reducer adopts the 90-degree orthogonal transmission of the first-stage bevel gear and the combined transmission of the two-stage satellite transmission structures, is lowered in the integral height after being provided with a motor, needs the small-volume rotor cover, is convenient to produce with low cost, transport and install on site, has large bearing capacity and impact resistance capacity, long service life, high speed ratio adjustment precision and is applicable to the wind-power generation of the large-size wind field.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a pitch-variable deceleration device suitable for wind power generation. Background technique [0002] With the gradual improvement of people's awareness of energy saving, environmental protection, and pollution-free and the development of technology, wind power, as a renewable energy source, has been developing rapidly all over the world. [0003] Wind power generation is driven by the wind to rotate the generator. The magnitude and direction of the wind directly affect the rotation speed of the wind wheel. If it is not well controlled, it will easily lead to unstable power generation frequency and cannot be used. Therefore, in addition to the yaw The reduction device changes the wind bearing angle to adapt to the unpredictable wind direction, and the pitch reduction device is also required to change the windward angle of the blades, so that the wind turbine can run stably and generate e...

Problems solved by technology

[0005] In order to solve the problem that the pitch reduction device for wind power generation in the prior art has a large volume, increased installation space, and heavy weight, resulting in an increase in the volume of the rotor cover where the pitch reduction device is installed, difficulty in manufacturing, high production costs, and the speed of the pitch reduction device The ratio adjustment accuracy is poor, and there are large speed ratio errors. The purpose of the present invention is to provide a rotor cover with small volume, light weight, small volume for installation, convenient manufacture, low cost, small speed ratio error, and accurate adjustment.
