Abstract
The research and design of the intelligent gear tooth distance error measuring instrumentt are involved in this thesis.After the study of the present error measuring instrument, the paper designs the measuring instrument for the gear tooth distance error of the middle and middle gears..?Its characteristics lie in small size, convenient measurement, convenient for saving space and easy to use..
The error of single and multiple pitch measurement is realized, and if the software part is developed, it can measure tooth profile, tooth profile error, etc..?Design and development of the design and software of the design and the electrical sub measurement and controlling parts of the design and the electrical sub measurement and control system.?On the basis of the stability accuracy, the mechanical part is as far as possible to make the structure simple, in order to reduce the accumulation error and reduce the cost.?In the aspect of intelligence by SCM system, realize the automatic data collection, automatic measurement, automatic data processing, automatic display and print the measuring results of "flowing water" measurement process, save manpower and time measurement.?In terms of computation with reference to numerous domestic and foreign advanced research results, combined with the subject characteristics, selection of the least square method is used to calculate a single tooth pitch error, the choice of relative method for measuring a plurality of teeth cumulative pitch error has the characteristics of simple.
This topic statement at the end of instrument measurement and working environment make the economic feasibility and environmental analysis, with the design of products covers an area of small space, manufacturing cost is low and the operation is simple, intelligent measurement, such as a series of characteristic, and is very suitable for small and medium enterprises, small and medium-sized zero batch production.?In addition to the design of the product operation noise is low, no pollution.?The advantages of this design have excellent prospects for the market..
