弹性力偶盘车装置
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。 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； 由于原装置力臂过长， 小齿轮也 为悬臂结构装配， 二者在受力后容易产生较大变形， 影响到齿间正确啮合， 此外， 电动机随着装置一起旋转， 会产生电线缠绕。
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， 使原来繁琐笨重的机组盘车能够轻便快捷的完成。
.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减速机 2和电机 1， 减速 机 2和电机 1均布安装， 或者成 180Q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通过键槽 83或者立柱 84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。
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， 使得被动设备转子 12受力均衡、 平稳。
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。 或者在大齿轮的上面与平行 键 10对应的位置设有立柱 84， 用来传递扭矩。这种情况下， 联轴器的键与 立柱高度相对应， 此时， 相当于有 180Q空回角。
弹性力偶盘车装置的工作原理是： 当控制机构送电后， 沿圆周方向均 匀分布的或成 180Q对称位置的电机 1分别带动减速机 2、 小齿轮 7转动， 小齿轮带动与其啮合的大齿轮 8转动。 由于大齿轮受到均衡切向力的作用， 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。 附图说明

该弹性力偶盘车装置， 用于重型水轮发电机组的轴系调整中心， 安装 在机组的上机架 6上。 在被动设备上机架 6上连接有弹性支架 5。 图 2、 图 3中表示出弹性支架 5包括有上环 51和下环 52， 上环与下环之间有 12个 弹性体 53连接。 上环 51是直径为 2.8米的圆环， 下环 52是直径为 4.1米 的圆环， 弹性体 53是由弹簧钢片制成的， 截面为槽形。 弹性支架上连接有 壳体 4, 壳体 4是圆环形状， 断面呈 U形。 水轮发电机组的上机架 6与弹 性力偶盘车装置之间为弹性连接。壳体 4上面紧固连接壳体盖板 3，在壳体 盖板上面安装两对共包括 4台减速机和电机， 每一对两台减速机和电机成 180Q对称布置， 形成两个力偶， 同步均衡作用在水轮发电机组的转子上。 选用电机的功率为 0.75千瓦、 转速为 1500转 /分钟； 减速机的输出转速 0.8 转 /分钟。 减速机输出轴伸入壳体盖板 3下面的壳体 4内， 小齿轮 7、 大齿 轮 8的模数均为 10。 大齿轮的齿体 81在壳体内， 大齿轮的内圆壁 82上有 键槽 83， 由平行键 10连接大齿轮和联轴器 9。
两个平行键 10成 180Q对称位置分布，根据被动设备转子具体结构， 联 轴器 9是对分式结构， 由两半组成， 联轴器 9与被动设备转子 12之间用 10 块径向联板 11连接。
实施例 3
该弹性力偶盘车装置用于特重型水轮发电机组的轴系调整中心， 弹性 力偶盘车装置采用三对共包括 6台同型号的减速机和电机。 每一对 2台减 速机和电机成 180Q对称布置， 形成 3个力偶， 同步均衡作用在水轮发电机 组的转子上。图 6表示在大齿轮 8的上面与平行键对应的位置设有立柱 84， 用来传递扭矩。这种情况下，联轴器的键与立柱高度相对应，相当于有 180Q 空回角。 此时的弹性力偶盘车装置结构由图 7表示。
将弹性力偶盘车装置安装在被动设备的机架时， 不论是偶数个或者奇 数个， 只要均匀布置安装， 都能实现本发明目的。
