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.     

Investigating the kinematic error in a hydraulic comparator

Conclusions In order to eliminate the kinematic error and raise factor, and hence raise the sensitivity of the instrument, it is necessary to use hydraulic comparators which provide a constant pressure on the diaphragm due to the liquid head independently of the displacement of the instrument's measuring rod.     

Time measurements of the kinematic and dynamic parameters of reduction gears

Phase and time methods of measuring the dynamics of reduction gears are compared. The features of the various procedures of time measurements are analyzed. It is shown that it is possible to determine the kinematic error of a reduction gear from the results of time measurements.
