目前,由于滚刀检查仪的生产和应用尚不多,在许多工厂中仍普遍用影象法来测量滚刀的齿形误差。影象法测量滚刀齿形的方法虽然用得很普遍,但精确度如何,却不多见有分析。本文拟从影象法测量齿形的原理出发,试对这种测量方法的精确度略作分析,笔者希望自己的浅见能引起同志们的批评和讨论,以求对此能得到比较明确的认识。 At present, due to the production and application of the hob tester is not yet available, in many factories is still commonly used imaging method to measure the gear hob error. Although the method of measuring the hob tooth shape by imaging method is widely used, the accuracy is not so much analyzed. This article intends to start from the principle of image method to measure tooth shape, try to make a slight analysis of the accuracy of this measurement method. I hope my own humble opinion can arouse the criticism and discussion of the comrades in order to get a clearer understanding .
