STUDY OF THE EFFICIENCY FACTOR OF SLIDING BEARINGS OF THE NEW CONSTRUCTIVE SOLUTION OF MULTISTAGE REDUCER

The article deals with the issues of quantitative assessment of the internal resistance of oil in sliding bearings of the new constructive solution of two-line three-stage reducer intended for use in transmission mechanisms of machines and devices. Based on the analysis of possible kinematic diagrams of the new constructive solution of reducer, it was determined that the directions of rotation of the driving and driven shafts coincide with the directions of rotation of block gears mounted on sliding bearings. In this case, the resistance in the sliding bearings becomes a useful driving force, which becomes a useful factor characterizing the internal driving force of the oil. This improves the reliability of the mechanism, as well as significantly reduce the energy consumption of the mechanical transmission. Based on the results of calculations, it was determined that the efficiency factor of the new constructive solution of a three-stage reducer is about 2% higher than in classic reducers.
