Обґрунтування конструктивних параметрів ножової стружкодробарки

The paper investigates the influence of gaps δ between movable and fixed knives of the chip crusher; the speed of rotation of the shaft n; the mass and material of chips m to be crushed on the torque of the Mkr shaft of the crusher. The following subjects were studied: shavings of carbon steel grades (steel 15, 25, 45) shavings of alloyed steel grades and high-alloy steel grades (steel 40x, 25xgt, 20x13) and shavings of titanium alloys (VT16, VT20) as a result of chip grinding studies and after generalization of experimental data and their mathematical processing, the statistical dependences obtained during experiments were approximated by various functions. Estimating the relative approximation error, the optimal one was selected from the obtained functions. Correlation and regression analysis and the Statistika10 application program for mathematical data processing were used to build mathematical models. As a result of the conducted research, recommendations were developed that can be used by design organizations in thedesign of knife chip crushers and in the development of technological processes for grinding chips from various materials.
