【摘要】 大型高精度齿轮广泛应用在水利发电、矿山冶金、大型工程机械等行业,在国民经济和国防工业中起着十分重要的作用。但由于大型齿轮的检测技术尚不完善,测量手段难以满足机械设备制造业迅速发展的需求,所以深入研究大齿轮的测量技术,开发性价比高、精度适中、简洁实用的大型齿轮测量仪是十分必要的。本课题在详细调研大型齿轮的加工及检测现状的基础上,提出了一种新型的大齿轮在位测量方案。该方案基于坐标测量原理和测量坐标系与加工坐标系的统一思想,主要以在位测量仪自身的测量运动实现大齿轮相应技术参数的测量。本文的研究工作如下:1、设计了一种新型的大型齿轮在位测量仪的结构。该仪器具有六个自由度,可实现测量坐标与加工坐标的统一,能够以自身的坐标系和测量运动实现大齿轮在位测量;对所制造出的仪器机构进行了定标测试及测量分析。2、开发了仪器的控制系统。基于仪器机械系统的特点,控制系统采用“PC+运动控制卡”的形式,可实现位置闭环控制;该系统由运动控制部分、坐标测量部分、状态检测与保护部分、数据采集部分等组成。3、利用C++Builder设计并调试了测量控制软件。该软件实现了齿向误差与齿距偏差的测量与误差的评定,输出了评价数据及曲线。4、分析了齿形测量的系统误差。基于空间解析几何方法,从理论上深刻阐述了该仪器在对大齿轮齿形测量时的系统误差,为齿轮测量误差的分析提供一种新的思路。综上所述,本文完成了大型齿轮在位测量仪的结构及其控制系统的设计与调试,并通过实验初步验证了这种大齿轮测量方案的可行性,为大齿轮测量提供了一种新的思想与途径。更多还原

【Abstract】 The large-scale high-accuracy gear is applied in industries such as waterpower, mine metallurgy, large-scale engineering machinery broadly. It is playing very important role in national economy and national defense industry. While the detecting technology of large-scale gear is not perfect, measure meaning is difficult to satisfy fast development of machinery equipment manufacturing industry’s demands, therefore, it is necessary to study deep into the measurement technology, exploit high rate of quality and price, moderate precision, and compact applied large gear measure instrument.This task suggested one kind of new large gear on-line measure project on the basis of investigating and studying for the large gear’s processing and inspecting current situation in detail. This scheme is basis on the uniform idea in coordinate measuring principle, measuring coordinate system and process coordinate system, mainly to realize the large gear corresponding technology parametric measurement through the measure instrument’s own measure motion. The research works of my thesis as follows:1. Have designed one late-model structure that is a large gear on-line measure instrument. The instrument has six free degrees, could realize the unification between the measuring coordinate and processing coordinate, could realize the on-line measure through it’s own coordinate system and measurement motion; and have taken picketage tests and measures analysis for the instrument organization manufactured.2. Have developed the instrument controlling system. Owing to the characteristic of instrument machinery system, the controlling system adopt the format of "PC + movement controlling cards", could realize location close-cycle controlling, but realizing location, the system is composed of moving controlling part, coordinate measuring part , state and protecting part , data collection part and so on.3. Making use of C++Builder to design and test measurement controlling software. The software has realized the measure and assessment of alignment errors and tooth pitch deviation,exported the assessment data and curve.4. Have analyzed the system error in profile measures. Owing to space analytic geometry method, set forth the system error being an instrument to measure the large gear profile measurement theoretically, providing a new thought for the analysis of gear measure error.To sum up, this thesis has accomplished the design and debugging of the organization and controlling system for large gear on-line measure instrument, and validated first and foremost that this measure scheme is feasible, providing one kind of new thought and approach to large gear measurement.更多还原
