Abstract


Improving the quality of finishing is an actual task, because it improves the efficiency of mechanisms, reduces noise, vibration, increases the durability of gears containing gears.

The purpose of the study was to obtain a technique for predicting the relationship between the stability of grinding wheels and the quality of gears resulting from the influence of process parameters during finishing.

To achieve the goal, the following tasks were solved: determination and study of the influence of the parameters of the technological process at the finishing machining of gears on quality indicators; development of a methodology for predicting the stability of the grinding wheel between corrections based on the data obtained.

Parameters of the technological process for the study determined the roughness Ra, the radial runout of the sprocket, the error in the direction of the teeth, the deviation of the profile of the tooth from the theoretical involute profile.

Based on the results of processing and statistical analysis of the experimental results, a mathematical model is obtained that describes the variation of the roughness parameter Ra in the form of a linear response function.

The resulting ratio shows the relationship of the roughness Ra of the machined surface with parameters such as wheel speed, radial feed and vertical feed. On the optimization parameter, the listed factors influence proportionally, as indicated by linear effects. In this case, the greatest influence is exerted by the speed of the circle and the pair interaction of the speed of the circle and the radial feed. The least influence is exerted by the vertical feed, and what is especially interesting is that the pair interaction of the speed of the circle and the vertical feed was not significant.

The obtained data allow modeling the changes in the basic quality parameter Ra of the surfaces of the gear teeth at the final gear grinding by the method of continuous grinding gear grinding.

Based on the results of the experiment, a technique has been developed for predicting the relationship between the stability of grinding wheels and the quality of gears from the influence of the components of technological processes during finishing.
