Gearbox device for airplane thruster, has elastomer elements arranged in rotation direction of rotary elements between projections of one set of rotary elements and projections of other set of rotary elements of auxiliary gearbox

摘要

The gearbox device (31) has projections (39,41,59,61) which are in operative connection with the power transmission rotary elements (33,35,55) of auxiliary gearbox (13) of an airplane thruster (1). The projections of the rotating elements are partially spaced apart. The elastomer elements (43,57) are arranged in direction of rotation of the rotary elements between projections (39,59) of rotary elements (33,35) and projections (41,61) of rotary elements (33,55) of the auxiliary gearbox.
