摘要: 主轴颈作为船用柴油机曲轴的关键组成部分,其平行度的加工精度是保证曲轴强度和可靠性的决定因素之一。目前人工检测或非接触式检测方法存在一定的局限性,如自动化程度低、测量精度低或易受表面因素影响等;因此,提出基于无线传输的接触式检测方法,通过设计接触式传感器环形测量装置依次采集主轴颈多处轮廓数据,利用空间解析几何原理提取轮廓点坐标并进行拟合分析,进而实时获得加工过程中主轴颈的平行度。试验结果表明,曲轴主轴颈平行度误差最大为9.65 %,该检测方法可有效对曲轴主轴颈与中心线平行度进行检测,为曲轴在机检测提供了理论基础。

Abstract: Main journal is crucial for the crankshaft of the diesel engine. The machining accuracy of parallelism is one of the determining factors to ensure the strength and reliability of the crankshaft. At present,there are some limitations in manual or non-contact detection methods,such as low automation,low measurement accuracy or susceptible to surface factors.Therefore,a contact detection method is proposed based on wireless transmission. By designing a contact sensor ring array device to collect data of the main journal in turn,coordinates of contour points are extracted and analyzed by using the principle of spatial analytic geometry.The parallelism of the main journal is obtained in real time during working time. The experimental results showed that the maximum error in detecting the parallelism of the main journal was 9.65 %. This detection method can effectively measure the parallelism between the crankshaft main journal and the centerline,providing a theoretical basis for crankshaft in machine inspection.

Key words: main journal of crankshaft, parallelism, contact detection
