Embodiment Construction

[0019] The present invention uses external splines on the main input shaft to connect with the internal splines of the planet carrier of the first-stage planetary gear system. The main input shaft is supported by two bearings, and the two bearings are supported by the main housing; The planetary gear can rotate around its axis, which is a radially rigid shaft, the ring gear and the housing are rigidly connected together, and the sun gear shaft is a rigid support shaft; the sun gear shaft The power can be directly transmitted to the generator through the coupling, or it can be connected with another planetary gear train or speed-up transmission, and then transmitted to the generator after being connected with the coupling; the planetary gear train is adjusted to ensure load balance.

[0020] The nature of the present invention will become clearer from the following detailed description of a preferred embodiment, which is intended only to illustrate the invention, which is an app...

Abstract

The invention belongs to the technical field of gear transmission and relates to a fan transmission device, one end of a main input shaft of the fan transmission device is linked with a wheel hub, the other end is an external spline and is linked with an internal spline of a first-stage planetary gear train planetary carrier, the main input shaft is supported by two bearings, and the two bearings are supported by a main housing; and a first-stage planetary gear consists of a sun gear, a gear ring and a planetary gear mounted on the planetary carrier, wherein the planetary gear rotates around a shaft thereof, the shaft is a radial rigid shaft, the gear ring is in rigid linkage with the housing, and the shaft of the sun gear is a rigid support shaft. The fan transmission device has the advantages of smaller safety factor, higher reliability and lower mounting and maintenance costs according to the design in the aspect.

Description

technical field [0001] The invention belongs to the technical field of gear transmission, and relates to a fan transmission device. International Patent Classification Number: B02B7 / 00. Background technique [0002] Wind turbines use transmissions to increase the speed and decrease the torque of the blades in order to generate electricity. Key factors to be considered in its design include: power generation efficiency, equipment reliability, and initial cost of manufacture and installation. [0003] Fans usually include: blades, hubs, input shafts, planetary gears or other gears, generators, housings, towers, etc. When designing a wind turbine, dynamic loads caused by local fluctuations in wind speed and direction are important factors to be considered. Because the bending and deformation of the transmission part will lead to poor load sharing between different planetary gears, resulting in short life of the transmission part, a large safety factor should be taken in the ...
