specific Embodiment

[0041] like Figure 1 to Figure 6 As shown, a high-power multi-branch star gear transmission device in this embodiment includes a box body 2, a support plate 3, an input shaft 1, a gear transmission system 4 and an output shaft 5, and the support plate 3 is fixed on the In the box body 2 , the gear transmission system 4 is installed on the box body 2 and the support plate 3 , and the input shaft 1 and the output shaft 5 are connected to both ends of the gear transmission system 4 .

[0042]The box body 2 is cylindrical and has two supporting bases, which are used to fix and support the entire planetary gear transmission, and are installed between the main engine and the propeller.

[0043] The support plate 3 is fixed in the box 2 by bolts, and the gear transmission system 4 is fixed by bearings.

[0044] The input shaft 1 connects the main engine and the gear transmission system 4 to provide power for the entire transmission.

[0045] The gear transmission system 4 is divid...

Abstract

The invention discloses a high-power multi-branch star-shaped gear transmission device which comprises an input shaft, a box body, a supporting plate, a gear transmission system and an output shaft. The supporting plate and the gear transmission system are mounted between the box body and the output shaft; the gear transmission system is fixed on the supporting plate and the box body; the input shaft penetrates through the box body and is connected with the gear transmission system, and the output shaft is connected with the gear transmission system; the main engine transmits input power to the gear transmission system through the input shaft, the input power is divided and then gathered through the gear transmission system, and the input power is output to the propeller through the output shaft. Large torque can be shared to gears of different levels, the load upper limit of the whole system is improved, larger torque can be transmitted, and the transmission ratio is improved.

Description

technical field [0001] The invention belongs to the technical field of transmission, in particular to a multi-branch star gear transmission. Background technique [0002] The power split transmission system has the advantages of strong bearing capacity, large transmission ratio and compact structure, and has been widely used in high-power power transmission. In low-speed and heavy-load power systems, high-power herringbone gear transmissions are widely used. At present, the common power split transmission systems mainly include two branches, three branches and four branches, and systems with more branches are rare. [Chinese invention] CN201510173879.4 discloses a power branch transmission mechanism, which can equally divide the power into six branches, but has disadvantages such as a large number of gears and a complex structure. [Chinese invention] CN201710142715.4 discloses a planetary transmission system with a double-row parallel and evenly distributed shunt structure o...
