Problems solved by technology

[0002] At present, most of the vertical axis wind turbines are directly connected to the windmill and the generator. There is a problem: during the rotation of the windmill, due to the height of the fan, it is easy to shake, and the swinging force is also very large, and the swinging force is directly applied to the generator, which is easy Cause damage to the generator due to swaying and reduce the number of revolutions of the generator, affecting power generation efficiency

Embodiment Construction

[0019] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0020] In an embodiment, a connection structure between a vertical-axis windmill and a generator includes a vertical-axis windmill, a self-aligning bearing mechanism, and a generator, and the vertical-axis windmill and the generator are connected together through a self-aligning bearing mechanism and arranged vertically; said The self-aligning bearing mechanism includes a self-aligning bearing 9, a transmission shaft 11, an upper flange 10 of the transmission shaft, and a lower flange 12 of the transmission shaft. The shaft windmill is connected, the lower flange of the transmission shaft is arranged at the lower part of the transmission shaft, and is connected with the generator, and the self-aligning bearing is located between the upper flange of the transmission shaft and the lower flange of the transmission shaft.

[0021] The generator is p...

Abstract

The invention relates to a structure for connecting a vertical shaft windmill with a power generator, which belongs to the technical field of vertical shaft wind power generators. The invention has the technical scheme that the vertical shaft windmill and the power generator are connected together through an aligning bearing mechanism and are vertically arranged, wherein the aligning bearing mechanism comprises an aligning bearing (9), a driving shaft (11), a driving shaft upper flange (10) and a driving shaft lower flange (12); the driving shaft is matched with the aligning bearing; the driving shaft upper flange is arranged at the upper part of the driving shaft and is connected with the vertical shaft windmill; and the driving shaft lower flange is arranged at the lower part of the driving shaft and is connected with the power generator. The structure has the beneficial effects that the action force can be automatically adjusted to be acted on the aligning bearing; the windmill is ensured not to shake by continuously and automatically adjusting the center; and the swing force acted on the power generator is offset by the aligning bearing, so that the power generator and the vertical shaft windmill can be used for automatically adjusting the center, normal operation of the power generator is ensured, and the power generation efficiency is improved.

Description

technical field [0001] The invention relates to a connection structure between a vertical axis windmill and a generator, and belongs to the technical field of vertical axis wind power generators. Background technique [0002] At present, most of the vertical axis wind turbines are directly connected to the windmill and the generator. The problem is that during the rotation of the windmill, due to the height of the fan, it is easy to shake, and the swinging force is also very large, and the swinging force is directly applied to the generator, which is easy. Cause damage to the generator due to swing and reduce the number of revolutions of the generator, affecting power generation efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a connection structure between a vertical axis windmill and a generator, so that the center of the generator and the vertical axis windmill can be automatically adjusted to improve power generation eff...
