MECHANISM OF PARRYING SWASH PLATE TORQUE Russian patent published in 2010 - IPC B64C27/32 B64C27/00 

FIELD: transport.

SUBSTANCE: invention relates to rotary-wing flight vehicles, particularly to swash plates. Proposed mechanism 60 comprises torque parrying shaft 62 counteracting swash plate force and fitted on rotor shaft 14 U. Built-up bearing 64 runs on shaft 62 to allow five degrees of freedom: spherical, linear along rotor axis and crosswise elasto-pliable. The latter are provided by set of elastic plates, rigid tangentially and flexible radially. Inside said built-up bearings assembly a spherical bearing is arranged to turn around and slide along shaft 62. Mechanism 60 can be arranged rotation field on swash plate 48 R or in stationary field on fixed swash plate. On processing input signal of rotor pitch variation, mechanism 60 allows swash plate mount unit to move along rotor axis, to turn when swash plate inclines and displace radially.

EFFECT: simple, compact, and light mechanism.
