Embodiment Construction

[0010] figure 1 It is the schematic diagram of the embodiment of the speed-up device of the wind power generating set of the present invention, as figure 1 As shown, the embodiment of the speed-up device of the wind power generating set of the present invention includes a parallel shaft gear transmission mechanism 1 and a planetary gear transmission mechanism 2 connected to each other, and the main power output shaft 4 of the parallel shaft gear transmission mechanism 1 and the planetary gear transmission mechanism The secondary power input shaft 11 of the mechanism 2 is fixedly connected.

[0011] With the above-mentioned structure, the active power input shaft of the parallel shaft gear transmission mechanism is used to connect with the impeller shaft in the wind power generating set, and bear the load transmitted by the impeller shaft, because the parallel shaft gear transmission mechanism has a stronger bearing capacity and is more machined. Therefore, the rotation transm...

Abstract

The invention provides a wind generating set speeder and a wind generating set. The wind generating set speeder comprises a parallel-shaft gear drive mechanism and a planet gear drive mechanism, wherein the parallel-shaft gear drive mechanism and the planet gear drive mechanism are mutually connected in a driving mode, and a driving power-output shaft of the parallel-shaft gear drive mechanism is fixedly connected with a driven power-input shaft of the planet gear drive mechanism. According to the scheme, the driving power-output shaft of the parallel-shaft gear drive mechanism is used for connecting with an impeller shaft in the wind generating set and bearing the load which is passed by the impeller shaft. According to the wind generating set speeder, the bearing capacity depends on a part which is connected with the impeller shaft, namely, the parallel-shaft gear drive mechanism is connected with the impeller shaft. Due to the fact that the bearing capacity of the parallel-shaft gear drive mechanism is stronger than that of the planet gear drive mechanism, the bearing capacity of the wind generating set speeder is improved, and requirements that the wind generating set develops to the directions of upsizing and high power are met.

Description

technical field [0001] The invention relates to the structural technology of wind power generating equipment, in particular to a speed-increasing device of a wind power generating set and the wind generating set. Background technique [0002] As a clean and pollution-free renewable energy, wind energy has been paid more and more attention to its utilization. Among them, converting wind energy into electrical energy is an important form of wind energy utilization. A wind turbine is a power generation device that converts wind energy into electrical energy. [0003] Offshore is a place with relatively abundant wind energy reserves. Due to the particularity of offshore working conditions, the trend of increasing single unit power of offshore wind turbines is very obvious. [0004] In the wind power generating set, a gear speed increasing device is arranged between the impeller and the generator to increase the rotational speed input by the impeller to the rotational speed req...
