摘要：
The invention relates to a speed reducer comprising two intermediate lines for a turboprop engine, said reducer comprising: - an input line comprising an input shaft (ai) bearing an input gear wheel, - a first intermediate line comprising a first intermediate shaft bearing a first intermediate gear wheel, - a second intermediate line comprising a second intermediate shaft bearing a second intermediate gear wheel, - a spring (24) held by a frame (25), the spring (24) surrounding a longitudinal portion (29) of the input shaft (ai) in order to allow a movement of the input gear wheel (10) towards an equilibrium position corresponding to an equal distribution of the transmission of the power coming from the input shaft (ai) to the first intermediate shaft (a2) of the first intermediate line (17) and the second intermediate shaft (a3) of the second intermediate line (18).
