POSSIBILITY TO ENSURE THE TECHNICAL EFFICIENCY OF THE VERTICAL SPINDLE COTTON PICKER

Abstract

In order for the use of the vertical-spindle cotton picker, created in Uzbekistan, to be economically effective, it is necessary, first of all, to increase its completeness of harvest. This indicator depends on many factors. However, the most important factor is that the spindle friction drive function is inadequate. Friction forces between the friction drive belts and the spindle roller determine its tagging capacity. The magnitude of the friction force depends on the pressure of the belts on the roller, which in turn depends on the tension of the drive belts. The article analyzes how much the tension of the drive belts in economic conditions meets the requirements.Key words:completeness of cotton picking by the apparatus; friction drive; belt tension; traction ability; direction and magnitude of the absolute speed of the spindle tooth; moment of power; variability of the angular speed of the spindle; gripping power of the tooth
