Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power gear box with a self-reinforced structure. Background Art

[0002] The gearbox in a wind turbine is an important mechanical component. Its main function is to transfer the power generated by the wind rotor to the generator and make it obtain the corresponding speed. Usually, the speed of the wind rotor is very low, far from the speed required by the generator. It must be achieved through the speed increase effect of the gear pair of the gearbox, so the gearbox is also called a speed increaser. According to the overall layout requirements of the unit, the transmission shaft (commonly known as the main shaft) directly connected to the wind rotor hub is sometimes integrated with the gearbox. There is also a structure in which the main shaft and the gearbox are arranged separately, and a clamping sleeve device or a coupling is used to connect them. In order to increase the braking capacity of the unit, a brake device is often set at the input or output end of the gearbox, and the blade tip brake (fixed pitch wind rotor) or variable pitch brake device is used to jointly brake the unit transmission system. However, it still has the following disadvantages in actual use:

[0003] At present, the existing wind power gearbox lacks relevant reinforcement structure when in use, which leads to an unstable structure of the bearing seat and has certain limitations in use; or the existing wind power gearbox with a self-reinforced structure is usually a fixed integrated design. When the gears are worn out after long-term use, the gearbox cannot be disassembled and replaced quickly, and the gearbox can only be replaced as a whole, which has high maintenance costs and certain limitations in use; therefore, it is necessary to improve a wind power gearbox with a self-reinforced structure to solve the above problems.

[0010] Preferably, a large gear assembly is fixedly connected to the other side of the middle part of the upper surface of the gear box assembly, and the large gear assembly includes a large gear body and a No. 2 hexagonal gear shaft, the No. 2 hexagonal gear shaft is fixedly connected to the middle part of the two end surfaces of the large gear body, and a No. 2 bearing is sleeved on one end of the circumferential surface of the No. 2 hexagonal gear shaft.

[0011] Compared with the prior art, the utility model provides a wind turbine gearbox with a self-reinforced structure, which has the following beneficial effects:

[0012] This wind turbine gearbox with a self-reinforced structure has the effect of a self-reinforced structure by providing a first gearbox, a second gearbox and a reinforcement piece, thereby solving the problem that the existing wind turbine gearbox lacks relevant reinforcement structures when in use, thereby causing the bearing seat to be structurally unstable and having certain limitations in use.

[0013] The wind turbine gearbox with a self-reinforced structure has the effect of facilitating the disassembly of the gearbox and reducing maintenance costs through the provision of a gearbox assembly, which solves the problem that the existing wind turbine gearbox with a self-reinforced structure is usually of a fixed integrated design. When the gears are worn out after long-term use, the gearbox cannot be quickly disassembled and replaced, and the only way is to replace the gearbox as a whole, resulting in high maintenance costs and certain limitations in use.
