The paper presents a method for calculating the maximum power of the conveyor drive under the condition of the maximum heating temperature of the elements. To study the thermal regime of the drive, the drive was selected according to the motor-drum scheme. The peculiarity of this drive is the lack of fan and air cooling, which can lead to overheating. The main components that generate heat energy are an induction motor with a short-circuited rotor and a reducer. The space of the motor-drum is filled with working fluid, which performs the functions of lubrication and cooling of the system components. Analysis of the design of the motor-drum drive allowed to establish the quantitative characteristics of the sources of thermal radiation of the individual components of the drive, taking into account the peculiarities of the interaction of the components. Quantitative characteristics of the sources of thermal radiation of the individual components of the drive allowed to establish the mutual influences of different parts of the object of study on its temperature state. The heat balance equation is applied under the condition of uniform distribution of the heat field on the surface of the drive elements. The equation of thermal balance of the system motor-drum-environment allows to determine the limit values of the drive power at known geometric parameters of the system. Coefficient of convective heat transfer coefficients between the working medium and the drum wall and the drum wall and the environment are used to determine the total heat transfer coefficient of the working medium-drum-environment system. Analysis of the obtained data shows a significant limitation of the required drive power. Limited drive power does not allow this type of drive to be used for long conveyors. Increasing the power of the drive according to this scheme can be provided by forcibly cooling the working fluid or changing the design of the drive by increasing the surface in contact with the working medium. ; В роботі представлено методику ... |
