PLANETARY MECHANISM AND CORRESPONDING METHOD FOR PRODUCTION Russian patent published in 2016 - IPC F16H1/28 F16H55/08 F16H57/08 B64C27/12 

FIELD: machine building.

SUBSTANCE: invention relates to planetary mechanism and method for production of such planetary mechanism. Planetary mechanism (6) for aircraft (1), capable of flight in stationary point comprises sun gear (7), which turns about first axis (A) and has plurality of first teeth (11); fixed crown gear wheel (8), having plurality of second teeth (12); and, at least, two planetary gears (9a, 9b, 9c, 9d, 9e), each including multiple third teeth (13). Every planetary gear (9a, 9b, 9c, 9d, 9e) engages with crown gear (8) and sun gear (7) and rotates around appropriate second axes (B), which in turn, are capable to rotate around first axis (A). At least two of third teeth (13) are engaged simultaneously with corresponding second teeth (12) and additional two of third teeth (13) are engaged simultaneously with respective first teeth (11). Third teeth (13) include first side (16a) and second side (16b), which respectively have first angle (α1) of profile and second angle (α2) of profile, which are different from each other. Number (ZP) of third teeth (13) of every planetary gear (9a, 9b, 9c, 9d, 9e) differs from absolute value of half-difference ((ZC-ZS)/2) between number (ZS) of first teeth (11) of sun gear (7) and number (ZS) of second teeth (12) of crown gear wheel (8).

EFFECT: transmission of motion to rotor shaft is implemented in simple and noiseless manner.
