Problems solved by technology

[0004] As a relatively integral part, the gear box needs to be replaced and repaired as a whole when the planetary stage fails. The cost of aerial hoisting and replacement involved is high, and disassembly is very difficult. Additional large-scale lifting equipment and tooling are required for on-site maintenance. Large amount of engineering, high difficulty in replacement and high maintenance cost

Embodiment 1

[0037] see Figure 1-6 , the present invention relates to a detachable compact power split main transmission system, which includes a supporting ring gear 1, a primary planetary gear train 2, a secondary planetary gear train 3, a third planetary gear train 4, a nacelle system 5 and generator6.

[0038] The primary planetary gear train 2 includes a primary left flange 2.1, a primary planet carrier assembly 2.2, a primary right flange 2.3 and a primary sun gear 2.4; the secondary planetary gear train 3 includes a secondary ring gear 3.1 , secondary ring gear left bearing 3.2, secondary planetary carrier assembly 3.3, secondary sun gear 3.4 and secondary ring gear right bearing 3.5; the tertiary planetary gear system 4 includes a tertiary planetary carrier assembly 4.1, a tertiary flange 4.2, three-stage ring gear 4.3, generator mounting flange 4.4 and three-stage sun gear 4.5.

[0039] The first-stage planetary carrier assembly 2.2, the second-stage planetary carrier assembly 3....

Embodiment 2

[0048] see Figure 7-Figure 10 , the present invention relates to a detachable compact power split main transmission system, which is different from Embodiment 1 in that the first-stage planetary gear train 2 and the third-stage planetary gear train 4 are set in the support ring gear 1, so The third-stage ring gear 4.3 is arranged on the inner wall of the supporting ring gear 1, the right side of the first-stage planetary carrier assembly 2.2 is supported on the first-stage right flange 2.3 through a bearing, and the left side of the third-stage planetary carrier assembly 4.1 is supported by a bearing Supported on the primary left flange 2.1;

[0049] The generator 6 is fixed in the nacelle system 5 through a flange.

[0050] The three-stage sun gear 4.5 is connected with the input shaft of the generator 6 through a coupling, and finally drives the generator to rotate.

Abstract

The invention relates to a detachable compact type power-dividing main transmission system which is a wind power main transmission system. The detachable compact type power-dividing main transmissionsystem comprises a first-level planetary gear train, a second-level planetary gear train and a supporting gear ring. The first-level planetary gear train is arranged in the supporting gear ring, and the supporting gear ring is fixed in a cabin system through a plurality of bearings. The left end of the supporting gear ring is connected with a wind wheel through a flange, and the right side of thesupporting gear ring is connected with a second-level planet carrier assembly. The wind wheel is supported through the supporting gear ring. The structure is compact, and the supporting rigidity is high. The supporting gear ring is connected with a second-level planet carrier, and the wind wheel drives the second-level planet carrier while driving the supporting gear ring, so that power dividing is achieved. The gear ring is in floating connection with a cabin, the uniform loading performance is good, and the bearing capacity of the whole transmission chain system is high. A three-level planetary transmission structure is adopted, the bearing capacity is high, and the transmission speed ratio is large. The planetary gear train of each level is independent and detachable. The transmission chain system has the advantages of being high in power density, compact in structure, light in weight, high in bearing capacity, convenient to maintain and replace and low in cost.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a detachable and compact power split main transmission system, which is used in a wind power non-direct drive transmission system. Background technique [0002] Common non-direct drive wind power transmission systems are composed of gearboxes, main shafts, main shaft bearings, bearing housings, locking discs, and couplings. The wind wheel is connected to the gearbox through the main shaft, and the main shaft passes through one or two main shafts. Bearings and bearing seats are supported on the bottom plate of the nacelle. The main function of the main shaft is to support the entire wind rotor and withstand the bending moment and torque of the fan; the main function of the gearbox is to realize the speed matching between the wind rotor and the generator, and drive the generator to generate electricity; this kind of transmission The overall size of the chain is long...
