Abstract

The article describes a test stand with a spindle equipped with an active bearing preload system using piezoelectric actuators. The proper functioning of the spindle and the active system was associated with the correct alignment of the spindle shaft and the drive motor. The article presents two methods of shaft alignment. The use of commonly known shaft alignment methods with dial indicators is insuﬃcient from the viewpoint of being able to control this preload. This work aims at making the readers awarethat,forsystemswithactivebearingpreload,thelatestmeasuringdevicesshouldbeusedtoaligntheshaft.Theuseofcommonlyknownmethodsofequalizationwithdialgaugesisinsuﬃcientfromthepointofviewofcontrollingthispreload.Increasingtheaccuracyofshaftalignmentfrom0.1to0.01mmmadeitpossibletoobtaina50%reductioninthedisplacementoftheouterbearingringduringspindleoperation.

对中误差对主动轴承预紧模块机床主轴运行的影响

本文介绍了一种装有压电作动器主动轴承预紧系统的主轴试验台。主轴和主动系统的正常工作与主轴轴和驱动电机的正确对准有关。本文介绍了两种轴对中方法。从能够控制这种预紧力的角度来看，使用通常已知的带有表盘指示器的轴对中方法是不够的。这项工作的目的是使读者意识到，对于具有主动轴承预紧力的系统，应该使用最新的测量设备来校准轴。从控制预紧力的角度来看，使用常用的测量方法是不够的。将轴对准的精度从0.1 mm提高到0.01mm，使其有可能在主轴运行期间获得50%的减少外轴承的位移。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
