Device and method for fixing enclosure central shaft and fan blade connecting rod of generator

Abstract

The invention discloses a device for fixing an enclosure central shaft and a fan blade connecting rod of a generator. The central shaft, the fan blade connecting rod, the fixing device and the enclosure are fixed together; a claw disc is formed by an annular disc and a claw rod; a fixed disc is provided with a claw groove and a disc groove; a shaft end groove is arranged at the center of the disc groove; and the claw rod of the claw disc is fixedly connected with the fan blade connecting rod. The fixed disc is arranged at the inner side of the enclosure; the claw disc is arranged on the fixed disc, the annular disc and the claw rod are embedded in the disc groove and the claw groove, and the claw disc is fixedly connected with the fixed disc; the shaft end of the central shaft is inserted in the shaft end groove, and the enclosure, the fixed disc and the central shaft are fixedly connected with one other; and the fan blade connecting rod is fixedly connected with the claw rod. The fixing device has a simple structure, low material consumption in manufacturing and a low cost, is convenient to manufacture, and guarantees the connecting stability between the fan blade and the central shaft; and on the basis of the fixing device, the mode of connecting the fixing device with the central shaft and the connecting rod is introduced, the method is simple, the operation is easy, the application is wide, and the working efficiency is high.

Description

technical field [0001] The invention relates to a connecting device, in particular to a fixing device and a method for a connecting rod of a generator casing and a fan blade of a vertical axis wind power generator. Background technique [0002] The vertical axis wind turbine is a new type of high-efficiency wind turbine. Each connection has simple structure, low connection strength and poor wind resistance. Due to the rotation of the fan blade, the strength between the central shaft of the generator casing and the connecting rod of the fan blade is relatively large. Aluminum fixed plate, but due to the low hardness and poor strength of aluminum material, in order to ensure the connection strength of the central shaft and the connecting rod, the connecting surface between the fixed plate and the connecting rod is large, and the consumables are many, the cost is high, the strength is poor, and the service life is low. Low, can not meet the normal, stable power generation effi...

Problems solved by technology

[0002] The vertical axis wind generator is a new type of high-efficiency wind generator. This wind generator is mainly composed of 3 or 4 fan blades perpendicular to the ground, a generator, a flange, a central shaft, and a connecting rod. Each connection has simple structure, low connection strength, and poor wind resistance. Due to the rotation of the fan blades, the strength between the central axis of the generator casing and the connecting rod of the fan blades is relatively high. However, at present, the connection between the two is generally used Aluminum fixed plate, but due to the low hardness and poor strength of the aluminum material, in order to ensure the connection strength between the central shaft and the connecting rod, the connection surface between the fixed plate and the connecting rod is large, the consumables are high, the cost is high and the strength is poor, and the service life Low, unable to meet normal and stable power generation efficiency
