Reducer with two intermediate lines for a turboprop engine, turboprop engine comprising said reducer

摘要

The present invention provides an input line including an input shaft (ai) that supports an input gear, a first intermediate line including a first intermediate shaft that supports a first intermediate gear, and a second that supports a second intermediate gear. A first intermediate shaft (a2) from the input shaft (ai) to the first intermediate line (17), comprising a second intermediate line with an intermediate shaft and a spring (24) held by the frame (25); And a spring (24) to allow movement of the input gear (10) towards an equilibrium position corresponding to an equal distribution of power transmission to the second intermediate shaft (a3) of the second intermediate line (18). ) Relates to a speed reducer with two intermediate lines for a turboprop engine, which surrounds the longitudinal part (29) of the input shaft (ai).
