Embodiment Construction

[0012] The structure of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 , figure 2 , image 3 As shown, the device is composed of a support arm 2, a fan blade bracket 4, a positioning pin 5, a self-lubricating bushing 6, and a cotter pin 7. The positioning pin 5 is installed on the fan blade bracket. Positioning pin 5 is combined together, can do relative rotation around self-lubricating axle sleeve 6, cotter pin 7 is contained on the positioning pin 5. .

[0014] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than limit them. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements to the technical solutions of the present invention do not depa...

Abstract

The invention relates to a fan blade connecting device for a vertical-axis wind driven generator. According to the fan blade connecting device for the vertical-axis wind driven generator, self-lubrication shaft sleeves are adopted, it is guaranteed that the connecting portions of fan blades of the vertical-axis wind driven generator and supporting arms are good in abrasion resistance and long in service life, and cost is reduced. The fan blade connecting device is composed of the supporting arms, fan blade supports, locating pins, the self-lubrication shaft sleeves and cotters and is characterized in that each locating pin is installed on the corresponding fan blade support, the supporting arms are combined with the locating pins together through the self-lubrication shaft sleeves and can rotate relatively around the self-lubrication shaft sleeves, and the cotters are arranged on the locating pins. The fan blade connecting device for the vertical-axis wind driven generator has the advantages that the abrasion resistance of the connecting portions of the fan blades of the vertical-axis wind driven generator and the supporting arms is improved, the service life of the wind driven generator is prolonged, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a connecting device for blades of a vertical-axis wind power generator, which belongs to the technical field of mechanical manufacturing. Background technique [0002] Most existing vertical-axis wind turbine blades and support arms are connected by joints, which require rolling bearings, which not only costs a lot, but also brings difficulties to subsequent maintenance and repair. Contents of the invention [0003] The object of the present invention is to provide a connecting device for blades of a vertical-axis wind power generator, which adopts a self-lubricating bushing to ensure that the connection between the blades of a vertical-axis wind power generator and the support arm has better wear resistance and service life. It can also reduce costs. [0004] The object of the present invention is achieved in this way: the device is composed of a support arm, a fan blade bracket, a positioning pin, a self-lubricating bushin...
