ОЦЕНКА ЭНЕРГЕТИЧЕСКИХ ПОКАЗАТЕЛЕЙ УСОВЕРШЕНСТВОВАННОГО ПРИВОДА МНОГООПОРНЫХ ДОЖДЕВАЛЬНЫХ МАШИН, ТИПА «КУБАНЬ-ЛК1»

Abstract

The issues of assessing the energy performance of the improved drive of a multi-support irrigation machine (DM) operating in motion in the Kuban-LK1 circle are described. It is noted that in order to increase the efficiency of DM cart drives and increase the speed of their movement, it is necessary to develop geared motors with a high gear ratio. The most promising option seems to be the use of energy-intensive gearmotors equipped with wave transmission. The rationale for the use of highly efficient gearing is given through theoretical studies. It is indicated that today, in the design of machines of this type, wheel gears with ineffective worm gears are used, as a result of which a blocked connection and uneven peripheral wheel speeds are formed in the transmission of running systems, which leads to a decrease in efficiency. operation of gear motors. It is possible to eliminate such negative qualities of the operation of the Kuban-LK DM by equipping it with gearmotors with wave transmission. Experimental studies of the machine were carried out at Ozery JSC, Kolomensky district, Moscow region, on a prototype of an 8-bogie electrified multi-support DM “Kuban-LK1”. On four trolleys (No. 2, No. 3, No. 7 and No. 8), gear motors with wave transmission were installed on each wheel. Potatoes were watered. Agricultural background is a field planted with potatoes. The slope of the field along the water supply pipeline and in the direction of movement of the carts did not exceed ± 0.01. As a result of the research, operational indicators were obtained, presented in Table 1, which allowed us to draw the following conclusions: power consumption of the support trolley with a modernized drive when operating; two electric motors, is 300 - 370 W. Under the same conditions, a serial drive consumes 630 – 670 W. Thus, power savings occur due to increased efficiency. drive (η) from 0.5 to 0.8 and its unlocking, on average, by approximately 1.8 times.
