Description
(一)技术领域
本发明涉及一种用于立式水轮发电机组及其它转动设备轴系调整中心,靠弹性力偶矩驱动转子的专用工具,具体说是一种弹性力偶盘车装置。
(二)背景技术
立式水轮发电机组轴系调整中心,需要靠外力驱动转子,以便校核轴系各截面径向摆度值。这就要求驱动转速均匀平稳,停点准,而且在各停点时,置转子于充分自由状态,排除外力对转子施加的干扰,同时要求在现场操作方便、快捷。然而现在大部分设备制造厂家能够提供的驱动方法仍然沿用原始的人力直接驱动、吊车牵引的驱动方法,其安全性差、劳动强度大、工作效率低。本专利申请人曾有过两项专利,提出新的自动盘车装置,对传统的盘车方法进行改进:一项是92219180.8号专利,另一项是99222132.3号专利。但是还存在一些缺点:该两项自动盘车装置与转动设备的同心度标准低,自动盘车装置与转动设备的机架采用刚性连接,当盘车装置的轴线与转动设备转子的轴线稍有偏差时,驱动力矩过大和驱动力矩不平稳,使用时需花费许多调整时间;由于该装置力臂过长,在受力后容易变形,小齿轮也为悬臂结构装配,影响到齿间正确啮合,影响调整的准确度;电动机随着设备一起旋转,会产生电线缠绕。
(三)发明内容
本发明目的在于克服上述技术中的缺点,提出一种弹性力偶盘车装置,使其在用于立式水轮发电机组及其他转动设备轴系调整中心时,能够降低劳动强度,改善劳动条件,减少操作调整时间,提高工作效率,提高调整的准确度。
本发明目的由以下技术方案实现:本弹性力偶盘车装置,其特征在于在被动设备上机架6上连接有弹性支架5,弹性支架上连接有断面呈U形的壳体4,使被动设备上机架6与弹性力偶盘车装置之间为弹性连接,壳体上面紧固连接壳体盖板3,在壳体盖板上面安装有一对或数对减速机2和电机1,每对减速机2和电机1成180°对称位置布置,减速机的输出轴伸入壳体盖板3下面的壳体4内,输出轴上连接小齿轮7,与同在壳体内的大齿轮8的齿体81啮合,由平行键10连接大齿轮8和联轴器9,联轴器9固定连接在被动设备转子12上。
弹性支架包括有上环51和下环52,上环与下环之间有数个弹性体53连接。弹性体53是由弹性材料制作的,其截面形状是矩形,或者是槽形,或者是T形,或者是工字形,或者是圆环形,或者是其他的形状。当弹性力偶盘车装置中心与被动转子中心稍有偏差时,弹性支架5缓解因此产生的径向反抗应力。更便于现场操作,运行更加平稳与安全。
两个平行键10分别位于联轴器9直径方向的两端、成180°对称位置分布,根据被动设备转子具体结构,联轴器9是整体式或对分式,当联轴器是对分式结构时,联轴器9与被动设备转子12之间用数块径向联板11连接。由于电机1、减速器2、小齿轮7都是成180°对称位置布置,因而传递出的是力偶矩,使得被动设备转子12受力均衡、平稳,匀速缓慢转动。
位于壳体内大齿轮的齿体81,与壳体内的水平面和内侧面之间形成轴向滑动间隙13和径向滑动间隙14,构成滑动轴承,以保证大齿轮8与断面呈U形的壳体4同心旋转。
大齿轮内圆壁与联轴器之间留有空气间隙,并在相对应的位置上,沿联轴器圆周方向均匀分布三个调整同心度的顶螺钉15。调整顶螺钉15的伸缩,就可以调整静止部分与转动部分的同心度。壳体4为油箱,其内腔装有润滑油,保证滑动轴承正常工作。
大齿轮的内圆壁82上有键槽83,键槽上设有旋转空回角,便于设备的转子与外力脱开,使转子处于充分自由状态。
弹性力偶盘车装置的工作原理是:当控制机构送电后,装配在成180°对称位置的两台电机1分别带动两台减速机2、小齿轮7转动,对称分布的小齿轮带动与其啮合的大齿轮8转动。由于大齿轮受到一对均衡切向力的作用,以及轴向滑动间隙13和径向滑动间隙14构成的滑动轴承的约束,运行平稳。大齿轮8通过平行键10带动联轴器9,联轴器9通过联板11带动被动设备转子12平稳转动。弹性力偶盘车装置将被动设备转子12旋转到某一位置停止后,稍许倒车,将平行键10旋转至空回角处,使外力与被动设备转子脱离,被动设备转子便处于充分自由状态,确保测数的精确性。弹性力偶盘车装置在应用初装时,静止与转动部分的同心度用三支调整同心度的顶螺钉15调整,调整后,再将弹性支架5紧固连接在被动设备上机架6上,三支调整同心度的顶螺钉15退出。
本发明的优点是结构更加合理、简单,由于将调整同心度的顶螺钉位置设置的更加合理,调整同心度更加方便;弹性支架代替了以前的刚性支架,增加了自稳定调整性能,使得操作更加容易,转动时晃动减小;壳体盖板的使用,将原有的悬臂结构改为固定结构,根除了由于悬臂产生的变形,齿轮啮合运行过程更加平稳,提高了运行的准确性和精度,齿轮啮合传动在封闭的壳体内,提高了安全性,便于保养;也避免了电线缠绕。
