Abstract

一种旋转圈形零件内支撑气浮式静平衡装置，包括气浮腔体（1）、端盖（2）、支座（3）、支承柱（4）、圆盘座（5）和两个轴向定位装置（6），气浮腔体（1）内部设有工作气腔（1-2）和与工作气腔（1-2）相连通的多个圆柱形进气通道（1-3），工作气腔（1-2）位于气浮腔体（1）一端，气浮腔体（1）顶端加工有圆弧形的工作表面（1-1），工作表面（1-1）上加工有多个与圆柱形进气通道（1-3）相连通的进气孔（1-4），端盖（2）固定安装在气浮腔体（1）靠近工作气腔（1-2）一侧的端面上，端盖（2）与气浮腔体（1）的工作气腔（1-2）密封连接，端盖（2）上加工有与工作气腔（1-2）相连通的供气孔（2-2），端盖（2）底端与支座（3）顶端可转动连接，气浮腔体（1）远离工作气腔（1-2）的一侧通过支承柱（4）与圆盘座（5）连接，气浮腔体（1）的两侧分别沿轴线方向安装两个轴向定位装置（6）。一种基于该种旋转圈形零件内支撑气浮式静平衡装置的方法，包括以下步骤：S1、将待静平衡的旋转圈形零件放置于气浮腔体（1）上，调整标高及水平度，使旋转圈形零件处于水平位置； S2、外部供气通过工作气腔（1-2）和进气孔（1-4）在气浮腔体（1）的工作表面（1-1）和旋转圈形零件的内表面之间形成具有承载力的气膜，将旋转圈形零件浮起；S3、转动旋转圈形零件，若旋转圈形零件存在静不平衡，则含有不平衡量的相位会自动旋转至最低点静止，在该相位去重或者在其反向相位加重，重复上述过程，直至旋转圈形零件静止后最低点的相位随机，则完成旋转圈形零件静平衡操作。如此设置解决了现有的旋转圈形零件气浮式静平衡装置存在仅适用于零件宽度短的场合，无法对宽度长的旋转圈形零件静平衡的问题，能够实现对不同宽度旋转圈形零件静平衡。

Description

一种高精度旋转圈形零件内支撑气浮式静平衡装置及方法 技术领域
本发明涉及一种静平衡装置及方法，具体涉及一种高精度旋转圈形零件内支撑气浮式静平衡装置及方法，属于旋转圈形零件静平衡领域。
背景技术
旋转圈形零件(比如齿圈、轴套等)是制造业、航海、航空、航天等领域中广泛应用的一类零件。旋转圈形零件在制造过程中，由于材料缺陷、设计误差等因素的影响，不可避免的产生静不平衡质量。在旋转圈形零件随主轴旋转过程中，这些静平衡质量将造成系统异常振动，加剧设备磨损，甚至系统的灾难性破坏，严重降低系统的安全可靠性。静平衡技术能够减少旋转圈形零件静不平衡质量，降低设备、系统的振动水平，对于提高安全可靠性具有重要意义。
由于齿圈、轴套等旋转圈形零件外表面不是圆柱形，现有的平衡导轨、滚动轴承摆架台等静平衡装置无法直接用于旋转圈形零件静平衡，通常与转子和轴套等配合使用。但由于转子和轴套自身的不平衡质量，以及硬接触存在较大的摩擦力矩，导致旋转圈形零件静平衡精度严重下降。
国际公布号为WO 2020/224614 A1、国际申请号为PCT/CN2020/088949公开了一种名称为“用于转子静平衡的剖分式可调摆角的静压气体轴承装置及旋转圈形零件静平衡的气浮支承装置”的发明专利，具体公开了一种旋转圈形零件静平衡的气浮支承装置。但是该装置在对旋转圈形零件静平衡时存在以下几点问题：
(1)由于该气浮支承装置的气浮支承结构采用单支承的方式，且由于旋转圈形零件在静平衡时需要套设在气浮支承结构上，导致该气浮支承装置必须采用侧部支承的方式，侧部支承与单支承相结合的支承方式，致使现有的旋转圈形零件气浮式静平衡装置仅适用于零件宽度短的场合，无法对宽度长的旋转圈形零件静平衡。
(2)由于该气浮支承装置的气浮支承结构采用单支承的方式，导致该气浮支承装置只能调整标高，无法实现水平度的调节；
(3)由于该气浮支承装置的气浮支承结构与两侧轴向定位装置可调范围较小，无法对任意长度的旋转圈形零件实现轴向定位。
(4)由于该气浮支承结构内的工作气腔为一个整体空腔，使气浮支承结构顶端形成曲面薄板结构，大大地降低了气浮支承结构的强度和刚度，致使现有的旋转圈形零件气浮式静平衡装置仅适用于轻型零件的场合，无法对重型的旋转圈形零件静平衡。
综上所述，现有的旋转圈形零件气浮式静平衡装置存在仅适用于零件宽度短的场合，无法对宽度长的旋转圈形零件静平衡的问题。
发明内容

本发明还提供一种基于高精度旋转圈形零件内支撑气浮式静平衡装置的方法，包括以下步骤：

S2、外部供气通过工作气腔1-2和进气孔1-4在气浮腔体1的工作表面1-1和旋转圈形零件的内表面之间形成具有承载力的气膜，将旋转圈形零件浮起；
S3、转动旋转圈形零件，若旋转圈形零件存在静不平衡，则含有不平衡量的相位会自动旋转至最低点静止，在该相位去重或者在其反向相位 加重，重复上述过程，直至旋转圈形零件静止后最低点的相位随机，则完成旋转圈形零件静平衡操作。
本发明与现有技术相比具有以下效果：
1、本发明的气浮腔体1外部的工作表面1-1与旋转圈形零件内表面相互配合，外部供气进入工作气腔1-2内，气体通过多个进气孔1-4在气浮腔体1的工作表面1-1与旋转圈形零件内表面之间形成具有一定承载力的气膜，将旋转圈形零件浮起后进行静平衡。
2、本发明提供的一种高精度旋转圈形静平内支撑气浮式静平衡装置，不需要借助其他旋转部件，能够直接对旋转圈形零件静平衡，消除转子、轴套等旋转部件自身不平衡量的影响，并且旋转圈形零件与气浮腔体1之间是气体接触，摩擦力矩低，能够极大提高旋转圈形零件静平衡精度。
3、本发明的气浮腔体1采用两侧双支撑的方式，使得本发明的高精度旋转圈形静平内支撑气浮式静平衡装置既能够用于对宽度短的旋转圈形零件静平衡；与能够用于对宽度长的旋转圈形零件静平衡，大大提高了静平衡装置的通用性。
4、本发明可以通过转动支承柱4来快速调整气浮腔体的水平度，在转动支承柱4来调整气浮腔体一侧的高度时，气浮腔体1和端盖2与支座3沿销轴中心转动，能够快速调节气浮腔体1的水平度，提高静平衡效率。
5、本发明的气浮腔体1的两侧分别沿轴线方向安装两个轴向定位装置6，滑道6-1通过螺栓连接固定在气浮腔体1的底部，喷嘴6-3可通过喷嘴定位结构6-2在滑道6-1内沿轴向和垂向滑动，调整至旋转圈形零件端面位置，外部供气通过喷嘴6-3将气体喷至旋转圈形零件端面处，防止旋转圈形零件沿轴向窜动，能够适应不同宽度尺寸的旋转圈形零件，提高了静平衡装置的通用性。
6、本发明的气浮腔体1内部设有工作气腔1-2和与所述工作气腔1-2相连通的多个圆柱形进气通道1-3，与现有的气浮支承装置相比较，本发明的圆柱形进气通道1-3在气浮腔体1呈分散式排布，有效地提高了气浮腔体1的强度，使得本发明的气浮腔体1能够适用于重型零件的场合，进而能够实现对重型旋转圈形零件静平衡。而且所述多个圆柱形进气通道1-3分布位置为沿周向从中间至两端逐渐稀疏方式排列。气浮腔体1的工 作表面1-1顶部的进气孔1-4数量较多，可以提高本发明的承载力。
