COMPARATIVE ANALYSIS OF DIFERENT TYPE REDUCERS FOR WINCH DRUM DRIVING UNIT

Abstract

Thanks to modern technological advances, today is developed so many of different types of mechanical transmissions. They are differences in performance, dimensions, mass, efficiency ratio, and of course price. In the framework of this paper is to set the output parameters (puling force, rotations per minute) the concept of the ship's winch drum are developed and elaborated. Performed by calculation of its operating parameters (power and rotations per minute of electric motors, power transmission and gear ratio) its threedimensional model has been made. Then is analyzed the possibility of implementing different types of reducers due to the fact that there is a large difference in the torque, rpm and efficiency ratio in relation to the mass and overall dimensions. The paper also presents the results of mutual comparisons given reducers as well as guidelines for the selection of optimal solutions.
