Technical Field
The utility model relates to the technical field of threading pipes of wind power gearboxes, in particular to a threading pipe mechanism applied to a wind power gearbox.
Background
The gearbox in the wind generating set is an important mechanical component, and the main function of the gearbox is to transmit the power generated by the wind wheel under the action of wind power to the generator and enable the power to obtain corresponding rotating speed, usually the rotating speed of the wind wheel is very low and can not reach the rotating speed required by the generator for generating electricity, and the rotating speed is realized through the speed increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed increasing box. According to the overall arrangement requirement of the unit, sometimes a transmission shaft (commonly called a large shaft) directly connected with a wind wheel hub is integrated with a gear box, and the large shaft and the gear box are respectively arranged, and a structure of expansion sleeve devices or coupling joints is used for connecting the large shaft and the gear box. In order to increase the braking capacity of the unit, a braking device is often arranged at the input end or the output end of the gear box, and the unit transmission system is jointly braked by matching with a blade tip braking (fixed pitch wind wheel) or a variable pitch braking device.
The rubber sealing piece of the threading pipe on the wind power gear box can be invalid due to aging, so that lubricating oil can be leaked, but the replacement on the tower can not be carried out due to the limitation of the construction conditions on the tower, and the lifting and transportation cost for the maintenance of the lower frame is high.
Therefore, we propose a threading pipe mechanism applied to a wind power gear box.
