Embodiment Construction

[0031] figure 1 A speed reducer 10 with two intermediate transmission lines is shown very schematically, said speed reducer 10 mainly comprising four parts: an input line 12, an output line 14 and two intermediate transmission lines 16, the two intermediate transmission lines is driven by the input line 12 and in turn drives the output line 14 .

[0032] The different parts 12, 14, 16 of the reducer are usually mounted in a reducer housing (not shown here), the reducer comprising a first opening and a second opening, the first opening for the input line to pass through And for connecting the input line eg to the first part of the turbine, the second opening is for passing the output line through and connecting the output line to the second part of the turbine. For example, where the turbomachine is a turboprop, the first component is the turbine shaft of the turbomachine and the second component is the drive shaft of the propeller of the turbomachine.

[0033] The input line...

Abstract

The invention relates to a reduction gear (10) with two intermediate transmission lines (16), especially for a turbine engine, comprising an input line (12) and an output line (14), the output line being The input lines are driven via said intermediate lines, said intermediate lines being substantially parallel, characterized in that the speed reducer comprises load sharing means between said intermediate lines, said load sharing means comprising means for rotatably coupling Ball-and-socket means (30) of a first end of the input line, first means (34) for damping radial movement of said end of the input line, and opposing first means (34) for damping the input line Second means (34) for radial movement of the two ends.

Description

technical field [0001] The invention relates to a gear unit with two intermediate transmission lines, in particular for a turbomachine. Background technique [0002] The prior art includes documents US-A-3,772,934, EP-A1-0 636 813 and WO-A1-2013 / 150229, among others. [0003] A turbine may include one or more mechanical speed reducers. This is especially the case with turboprop engines, the propeller of which is rotated by the turbine shaft by means of a reducer. [0004] There are many types of speed reducers, such as planetary gear reduction mechanisms, sprockets, worm gears, intermediate transmission lines, and the like. The present invention mainly relates to a speed reducer (also known as a compound speed reducer) with a transmission line. [0005] In the prior art, reduction gears of this type comprise an input line and an output line, which is driven by the input line by means of two intermediate transmission lines. The power transmitted by the input line is divid...
