RESEARCH OF THE CONDITIONS OF FLUCTUATIONS IN GEAR COUPLINGS AT NONCOAXIALITIES OF THE CONNECTED SHAFTS
Article is devoted to consideration of conditions of appearance of variable forces and the moments in gear connecting couplings with an intermediate shaft at a discrepancy of axes of the connected shafts. This problem is relevant and important as gear couplings are widely used in rotor systems (in particular, in turbine plants), and their work often is followed by the increased vibrations with a rotation frequency. The dependences allowing to calculate variable forces and the moments at noncoaxialities of the connected shafts are received. Cases of absolutely rigid (not deformed) shaft and the real (deformed) shaft are considered. Requirements to rigidity of shaft and possible sizes of noncoaxiality which implementation allows to exclude variable forces in the coupling are developed.The direction of further researches on this subject is defined - conclusion of conditions of ensuring mobility in the gear couplings.
