Аналітичні дослідження роботи приводу кухонного комбайну

Abstract

В роботі запропоновано розробку удосконаленої системи керування електроприводом кухонних комбайнів. Теоретично обґрунтовано можливість ефективного використання системи керування електродвигуном кухонного комбайну зі зворотним за швидкістю і струмом якоря, розроблено електричну схему і визначено її необхідні електричні і конструктивні параметри. Виконано розрахунки потужності, що споживається при різних режимах роботи машини, розрахунок найбільш прийнятного передаточного відношення приводу і параметри зубчатої пасової передачі. Результати дослідження можуть бути використані для вдосконалення конструкцій побутових кухонних комбайнів.

The article presents the results of researches is development of the improved control of kitchen combines system. Depending on the type of processing, the mechanical properties of food and the tool used, the speed and the moment of resistance on the drive shaft are different. Modern food processors are mainly equipped with drives based on universal collector electric motors, which is due to a number of advantages over asynchronous and DC motors. As a result of the analytical study, formulas are obtained that allow determining the power consumption and productivity of the food processor when cutting food products depending on the geometric and structural parameters of the working bodies and the physical and mechanical characteristics of the processed material. In drive possibility of the effective use of the control the electric motor of kitchen system to the combine with reverse after speed and current of anchor, an electric chart is developed and certainly her electric and structural parameters are needed. The calculations of power which is consumed at the different modes of operations of machine, calculation of the most acceptable transmission relation of occasion and parameters of gearing of pass, are executed. Can be drawn on research results for perfection of constructions of domestic kitchen combines. Originality consists in that first in theory drive possibility of the effective use of the control the electric motor of kitchen system to the combine with reverse after speed and current of anchor, an electric chart is developed and certainly her electric and structural parameters are needed. It was found that the electric drive of the food processor will work with a maximum efficiency (55%) when using a disc for cutting vegetables and fruits which has diametrically opposite knives.Practical value consists in that can be drawn on research results for perfection of constructions of domestic kitchen combines.
