摘要

齿廓偏差测量，又名齿形测量，通常是在渐开线检查仪上进行测量的。渐开线检查仪可分为万能渐开线检查仪和单盘式渐开线检查仪。单盘式渐开线检查仪是用比较法进行齿廓偏差测量的，即将被测齿廓与理论渐开线进行比较，从而得出齿廓偏差。

随着工业化、信息化的不断进步，测量技术也日新月异。以前的单盘式渐开线检查仪暴露了一些缺点，例如测量齿轮时记录装置是一个百分表，齿轮每转过一定角度读取一个读数，不能连续测量记录。没有智能化和现代化的检测方法，就不能得到高精度的齿轮。

本文通过对国内外产品的调研，查阅相关资料手册等，完成了单盘齿廓测量仪的设计。主要包括前期的设计准备工作：通过查阅文献、科学调研等学习了解齿廓测量原理；之后对于单盘齿廓测量仪设计整体方案的创成和优化。用电感传感器代替测量装置，用步进电机代替手轮传动。确定用单片机系统控制步进电机转动，扩展显示器显示齿形误差数值并将结果打印出来。最后，根据之前的设计成果，对机械结构进行设计和零件的设计校核，还要进行二维图纸（包括总装图和零件图）的建立等。

Abstract

The tooth profile deviation measurement, also known as tooth profile measurement, is usually measured on an involute tester. Involute testers can be divided into universal involute testers and single disk involute testers. The single disk involute tester uses a comparative method to measure the tooth profile deviation, that is, to compare the measured tooth profile with the theoretical involute curve to obtain the tooth profile deviation.

With the continuous progress of industrialization and informatization, measurem-

ent technology is changing with each passing day. The previous single disk involute tester revealed some disadvantages. For example, when the gear is measured, the recording device is a dial indicator. Every time the gear reads a reading through a certain angle, it cannot record continuously. Without intelligent and modern detection methods, high-precision gears cannot be obtained.

This article through the investigation of domestic and foreign products, access to relevant information manuals, etc., to complete the design of a single disk profile measurement instrument.It mainly includes the preliminary design preparation work: learning the principles of tooth profile measurement by consulting literature, scientific research, etc.; and then designing and optimizing the overall plan for the single disk profile measuring instrument. Replace the measuring device with an inductive sensor and replace the hand wheel drive with a stepper motor. It is determined that the stepper motor rotation is controlled by the single-chip microcomputer system, the extended display shows the tooth profile error value, and the result is printed out. Finally, based on the previous design results, the design of the mechanical structure and the design of the parts were checked, and the two-dimensional drawings (including the assembly drawing and the parts drawing) were also established.
