An optical method of checking kinematic accuracy without a prototype

Conclusions

This method can be used for checking the kinematic accuracy of various mechanisms such as kinematic pairs, metal-working lathes, screws, worm gears, and other devices.

This optical method of nonprototype checking of the kinematic accuracy was used in practice in checking the accuracy of the chain feed of a gear-hobbing machine [1], which was constructed to the design of the author of this article by the gear transmission section of TsNIITMASh. The tests showed that the instrument can be recommended for use in industry.

A model of an instrument for checking the accuracy of screws was constructed under the author's guidance in the Moscow Engineering Evening Institute in conjunction with the Interchangeability Bureau of the Committee of Standards, Measures, and Measuring Instruments. Since the model was tested and certain modifications made, a second model is being constructed which can also be recommended for general use.
