Technical Field
The invention relates to the technical field of wind generating sets, in particular to a transmission assembly for connecting an impeller shaft and a main shaft of a wind generating set.
Background
In the mainstream wind generating set at present, the main components comprise an impeller component, a speed change component, a generator component and a tower. The impeller component, the speed change component and the generator component are all connected on the same axis in a very compact manner, so that the shaft end of the impeller and the shaft end of the main shaft are coaxially connected. The impeller assembly, the speed change assembly and the generator assembly are all placed on top of the tower. With the increasing of the single machine capacity of the generator set, the weight of the speed change assembly and the generator assembly is also increasing, and the height of the tower is also increasing. Thus, on the one hand, there are higher demands on the load-bearing capacity and weight of the tower, and on the other hand, the difficulty and cost of installation and maintenance are also increased.
Therefore, a novel transmission assembly for connecting the impeller shaft and the main shaft is required to be designed, so that the speed change assembly and the generator assembly are moved away from the top of the tower and placed at the bottom of the tower, the requirements on the bearing capacity and weight of the tower are greatly reduced, and the difficulty and cost of installation and maintenance of the wind generating set are greatly reduced.
Disclosure of Invention
The invention aims to provide a transmission assembly for connecting an impeller shaft and a main shaft of a wind generating set, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention adopts the technical scheme that:
a transmission assembly for connecting an impeller shaft and a main shaft of a wind generating set is characterized in that one end of the transmission assembly is connected with the impeller shaft, the other end of the transmission assembly is connected with the main shaft, and the two ends of the transmission assembly are not located on the same horizontal plane. The transmission assembly comprises a gear drive comprising a gear (2, 3, 4, 5) and a chain drive comprising a sprocket (6, 8) and a chain (7).
The gear (2) is coaxially connected with the impeller shaft (1) and then is orthogonal to the axial lead of the gear (3) for changing the axial direction of the impeller shaft transmission.
The axial lead of the gear (3) is coincident with the axial lead of the yaw bearing, so that the yaw function can be exerted.
The gear (4) is coaxially connected with the gear (3) and then is orthogonal to the axial lead of the gear (5) for changing the axial direction of transmission.
The chain wheel (6) is coaxially connected with the gear (5) and then connected with the chain wheel (8) through the chain (7) for increasing the center distance of the transmission shaft.
The chain wheel (8) is coaxially connected with the main shaft (9) so as to transmit mechanical energy generated when the impeller assembly rotates to the speed change assembly and the generator assembly.
The transmission assembly for connecting the impeller shaft and the main shaft of the wind generating set is used for transmitting mechanical energy generated when the impeller assembly rotates to the speed change assembly and the generator assembly, and the speed change assembly and the generator assembly can be placed at the bottom of the tower, so that the requirements on the bearing capacity and weight of the tower are greatly reduced, and the difficulty and the cost of installation and maintenance of the wind generating set are greatly reduced.

Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description. The following examples are intended to illustrate the invention but are not intended to limit it.
Referring to fig. 1, a schematic diagram of a transmission assembly for connecting an impeller shaft and a main shaft of a wind turbine generator system is shown, wherein one end of the transmission assembly is connected with the impeller shaft, the other end of the transmission assembly is connected with the main shaft, and the two ends are not in the same horizontal plane. The transmission assembly comprises a gear transmission comprising gears (2, 3, 4, 5) and a chain drive comprising sprockets (6, 8) and a chain (7).
The gears (2, 3, 4, 5) are all bevel gears with the same diameter and the same number of teeth.
The axial lead of the gear (3) is coincided with the axial lead of the yaw bearing, so that the impeller assembly can be enabled to change the direction horizontally by 360 degrees by utilizing the yaw bearing, and wind energy from different directions can be utilized to the maximum extent.
The chain wheel (6) and the chain wheel (8) have the same diameter and the same tooth number, and the axial leads thereof are parallel to each other and are positioned on the same vertical plane, thereby ensuring the high efficiency and stability of transmission under the condition that the chain (7) is longer.
The gear (3) is coaxially connected with the gear (4) and is fixed on the inner wall of the tower through a bearing; the gear (5) is coaxially connected with the chain wheel (6) and fixed on the inner wall of the tower frame through a bearing; the chain wheel (8) is fixed on the inner wall of the tower through a bearing.
Referring to fig. 1 and 2, fig. 2 is a schematic diagram of main components of a wind turbine generator set using the present invention, and according to this embodiment, through the two sets of bevel gear transmissions and the one set of chain transmissions, the transmission efficiency loss in the whole process is small, and the difference between the rotation speed of the main shaft and the rotation speed of the impeller shaft can be maintained small, so that the speed change component and the generator component can be moved away from the top of the tower and placed at the bottom of the tower, thereby greatly reducing the requirements on the bearing capacity and weight of the tower, and greatly reducing the difficulty and cost of installation and maintenance of the wind turbine generator set.
While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
