Abstract

The operation of the Mi-26 helicopters has shown that the operating time for rejection of splined gear couplings of the tail rotor transmission can differ by about 30 times. This fact is the reason for the search for dynamic processes that violate the stationary of the loading modes of the transmission couplings. Based on the analysis of the kinematics and dynamics of the clutch, it is shown in this work that when sliding in "tooth-spline" friction pairs, frictional self-oscillations can develop, leading to additional dynamic loads in the transmission elements and, as a consequence, a decrease in the working life of the clutches. The type of self-oscillations, their parameters (frequency, amplitude), as well as the stability of the transmission in relation to frictional self-oscillations depend on the tribological characteristics of the "tooth-slot" contact, which require additional experimental research. The results of this work can be useful in planning field tests and processing the data obtained.
