Meanwhile, with the gradual saturation of onshore wind fields, people gradually aim at the sea, and compared with onshore, offshore wind energy is richer and is not limited by the terrain, so that higher power requirements are provided for offshore wind turbines.

The wind power gearbox is different from a land wind turbine, the offshore wind turbine has complex working conditions, high transportation cost and difficult maintenance and puts high requirements on the service life, the weight and the safety of the wind power gearbox, in the traditional wind turbine transmission chain structure, an elastic support is required to be used for supporting the gearbox on a bottom plate of a cabin through a flexible support, when the wind turbine generates electricity, due to the influence of torque and bending moment transmitted by an impeller, the gear wheel box and the elastic support are displaced together, so that a shell of the gearbox cannot be always kept on the same axis with a main bearing, a planet carrier of the gearbox is supported on the shell through bearings on two sides respectively, the integral length and the weight of the gearbox are increased, and the integrated wind power transmission chain structure can improve the problems.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing an integrated form wind-powered electricity generation driving chain structure can reduce driving chain length and width, alleviates whole driving chain weight, simplifies the structure.

The technical scheme is as follows: the utility model discloses an integrated form wind-powered electricity generation drive chain structure, including gear box, planet carrier, main shaft bearing, bearing frame, locking dish and planet carrier bearing, the gear box sets up inside the cabin, and the planet carrier of power input one end in the gear box is connected through the locking dish with one end of main shaft, the main shaft other end is provided with main shaft bearing, and main shaft bearing sets up in the bearing frame, and the bearing frame passes through flange joint with the casing of gear box; the planet carrier bearing is arranged at the other end of the planet carrier connected with the main shaft and supports the planet carrier together with the main shaft bearing.

Preferably, an end surface of the bearing seat facing the gear box is connected to the flange by bolts.

Preferably, a gear ring is arranged in the gear box, the gear ring protrudes out of the outer surface of the gear box, and the end face of the gear ring, facing the bearing seat, on one side is connected with the flange through a bolt.

Preferably, an anti-corrosion flange sealing cover is arranged outside the flange, and covers a joint between the flange and the end face of the bearing seat and a joint between the flange and the end face of the ring gear.

Preferably, the housing of the gearbox is rigidly fixed to the nacelle floor.

Has the advantages that:

(1) the utility model discloses well gear box no longer needs the elastic support, consequently can reduce the width of whole driving chain greatly.

(2) The utility model discloses well gear box and bearing frame are direct through adapter flange connection, consequently can reduce the distance between base bearing and the planet carrier greatly to shorten main shaft length, reduce the length of whole driving chain.

(3) The utility model discloses in because the length and the width of whole driving chain wholly reduce to compare the traditional structure and reduced a bearing, consequently reduced the weight of whole driving chain, simplified the structure, the cost is reduced.

Detailed Description

The invention will be further elucidated with reference to the embodiments described hereinafter.

As shown in fig. 1, which is a side cross-sectional view of the present invention, the present invention includes a gear box 1, a planet carrier 2, a main shaft 3, a main shaft bearing 4, a bearing seat 5, a locking disk 6 and a planet carrier bearing 7, wherein the gear box 1 is arranged in a cabin and rigidly fixed with a cabin bottom plate, the planet carrier 2 at one end of power input in the gear box 1 is connected with one end of the main shaft 3 through the locking disk 6, the other end of the main shaft 3 is provided with the main shaft bearing 4, the main shaft bearing 4 is arranged in the bearing seat 5, the bearing seat 5 is connected with a housing of the gear box 1 through a flange 8, wherein an end surface of the bearing seat 5 facing one side of the gear box 1 is connected with the flange 8 through a bolt; a gear ring 9 arranged in the gear box 1 protrudes outwards from the outer surface of the gear box 1, and the end face of one side, facing the bearing seat 5, of the gear ring 9 is connected with the flange 8 through bolts.

The utility model discloses well flange 8's the outside is provided with the anticorrosive flange sealed cowling, including the flange sealed cowling covers the junction of

flange

8 and 5 terminal surfaces of bearing frame and the junction of flange 8 and ring gear 9 terminal surface, ensures that whole equipment can not receive external pollution destruction in long-term work.

The utility model discloses the other end that well planet carrier 2 and main shaft 3 are connected still is provided with a planet carrier bearing 7, and planet carrier bearing 7 supports planet carrier 2 with main shaft bearing 4 together.

In traditional fan drive chain structure, the gear box passes through the locking dish with the main shaft and is connected to install on the cabin bottom plate by base bearing and elastic support cushion cover together the utility model discloses well main shaft 3 still is connected through locking dish 6 with planet carrier 2, but the difference is, flange 8 directly links to each other with main shaft bearing 4's bearing frame 5, and, the gear box planet carrier both ends of traditional structure respectively need a bearing support, and the utility model discloses in, planet carrier 2 only need in the gear box 1 on the right side installation a planet carrier bearing 7 can, the opposite side then supports through main shaft bearing 4 with main shaft 2 together, reduces the distance between 3 bearings of main shaft and the planet carrier 2 greatly, thereby shortens 3 lengths of main shaft, reduces the length of whole drive chain.

Because the utility model discloses well gear box 1's casing has been fixed as a whole with main shaft bearing 4's bearing frame 5 and cabin floor complete rigidity, and in traditional framework, be the flexible support between the elastic support of gear box and the cabin bottom plate, during the fan electricity generation, because the influence of the moment of torsion and the moment of flexure that the impeller transmission was come, make gear wheel case and elastic support take place the displacement together, thereby the casing of gear box can not be with the main bearing remain throughout on same axis, therefore the planet carrier of gear box must be through each bearing support in both sides on the casing, consequently compare in traditional structure and compare, the utility model discloses save this part of elastic support, reduced the width of whole driving chain.

The utility model discloses because the length and the width of driving chain all compare traditional structure and have had holistic reduction to still reduced a bearing in the gear box, consequently simplified the structure of whole driving chain, reduce cost.
