[0002] The wind turbine is a kind of special power equipment. The transmission chain plays a very important role in the doubly-fed wind turbine. The main shaft system and the gearbox are connected by locking sleeves. After the gearbox is connected, the bolts on the locking sleeve need to be tightened to play a locking role. This process is time-consuming and labor-intensive, and the unit that has been hoisted in the wind field, when the transmission chain system is abnormal, the traditional transmission The chain system needs to remove the entire system, which is time-consuming and labor-intensive

A connection device between a double-fed fan main shaft system and a gearbox, including a main shaft side connection block, an intermediate elastic body and a gearbox side connection block, the main shaft side connection block is used to be installed on the main shaft of a double-fed fan main shaft system through threaded connection The connecting block on the side of the gearbox is used for positioning and connecting with the gearbox through the positioning key. The connecting block on the main shaft side is provided with a connecting protrusion, and the connecting block on the side of the gearbox is provided with a connecting groove that matches the connecting protrusion. Through the connecting protrusion The connection between the doubly-fed fan main shaft system and the gearbox is achieved by cooperating with the connection groove, and the middle elastic body is used to be installed between the main shaft side connection block and the gearbox side connection block. The device connects the main shaft and the gearbox through split connection, which can improve the assembly efficiency, and at the same time can ensure the normal operation of the main shaft and the gearbox when they are not completely concentric, and when the transmission chain system is abnormal, The main shaft system and the gearbox system can be handled separately to save costs.
Description
technical field [0001] The present invention relates to the technical field of wind power generating sets, in particular to a double-fed fan main shaft system and a gear box connection device, and also relates to a connection method for the above-mentioned double-fed fan main shaft system and the gear box connection device. Background technique [0002] The wind turbine is a kind of special power equipment. The transmission chain plays a very important role in the doubly-fed wind turbine. The main shaft system and the gearbox are connected by locking sleeves. After the gearbox is connected, the bolts on the locking sleeve need to be tightened to play a locking role. This process is time-consuming and labor-intensive, and when the unit is hoisted in the wind field, when the transmission chain system is abnormal, the traditional transmission The chain system requires the entire system to be removed, which is time-consuming and labor-intensive.
