Abstract

风力发电机风轮轴装置,包括风轮机轴座(1),在风轮机轴座(1)上固定有风轮轴(2),风轮轴(2)上安装有深沟球轴承(3),风轮座(4)插套在风轮轴(2)上且安装在深沟球轴承(3)上,风轮座(4)上固定有连接螺母(5),风轮固定连接在连接螺母(5)上,左边第一个风轮座到右边最后一个风轮座的距离(L)小于500mm。它的风轮轴设计较短,有利于保持风轮轴的稳定性,延长风轮轴的使用寿命。

Description

风力发电机风轮轴装置
技术领域
本实用新型涉及风力发电机技术领域,更具体地说涉及一种风力发电机的风轮轴。
背景技术
如图1所示,现有风力发电机的风轮轴A1安装在风轮机轴座A2上,风轮轴A1上固定在有轴承A3的内圈,轴承A3的外圈上固定有风轮座A4,内轮座A4上固定有连接法兰盘A5,风轮固定在连接法兰盘A5上。其不足之处是:它的风轮轴A1较长,从左边第一个风轮座A4到右边最后一个风轮座之间的长度L1为1800mm以上,这样风轮轴A1在工作时,由于它长度较长,轴易晃动,影响风轮的稳定性,同时易损坏风轮轴。
实用新型内容
本实用新型的目的就是针对现有技术之不足,而提供一种风力发电机风轮轴装置,它的风轮轴设计较短,有利于保持风轮轴的稳定性,延长风轮轴的使用寿命。
本实用新型的技术解决措施如下:
风力发电机风轮轴装置,包括风轮机轴座,在风轮机轴座上固定有风轮轴,风轮轴上安装有深沟球轴承,风轮座插套在风轮轴上且安装在深沟球轴承上,风轮座上固定有连接螺母,风轮固定连接在连接螺母上,左边第一个风轮座到右边最后一个风轮座的距离小于500mm。
本实用新型的有益效果在于:
它的风轮轴设计较短,有利于保持风轮轴的稳定性,延长风轮轴的使用寿命。
附图说明:
图1为现有技术的结构示意图
图2为本实用新型的结构示意图
图中:1、风轮机轴座;2、风轮轴;3、深沟球轴承;4、风轮座;5、连接螺母。
具体实施方式:
实施例:见图2所示,风力发电机风轮轴装置,包括风轮机轴座1,在风轮机轴座1上固定有风轮轴2,风轮轴2上安装有深沟球轴承3,风轮座4插套在风轮轴2上且安装在深沟球轴承3上,风轮座4上固定有连接螺母5,风轮固定连接在连接螺母5上,左边第一个风轮座到右边最后一个风轮座的距离L小于500mm。
工作原理:它由于边第一个风轮座到右边最后一个风轮座的距离L小于500mm。它的风轮轴设计较短,有利于保持风轮轴的稳定性,延长风轮轴的使用寿命。

Claims (1)
