Connecting structure for wind driven generator main shaft and wind power gearbox planet carrier

Abstract

The invention discloses a high-safety and high-reliability connecting structure for a wind driven generator main shaft and a wind power gearbox planet carrier. The connecting structure is characterized by comprising a plurality of double-fold anti-loose gaskets, each double-fold anti-loose gasket comprises a left anti-loose gasket body and a right anti-loose gasket body, each left anti-loose gasket body and each right anti-loose gasket body are each provided with a plurality of large anti-loose teeth which are circumferentially distributed along one axial end face of the gasket body at intervals, the angle of tooth corners of the large anti-loose teeth is larger than the angle of cam-shaped teeth of spiral corners of a threaded body on a bolt, each left anti-loose gasket body and the corresponding right anti-loose gasket body are assembled on one bolt in a left-right overlapped mode and located between a bolt cap of the bolt and a connecting pin, the large anti-loose teeth of each leftanti-loose gasket body are meshed with the large anti-loose teeth of the corresponding right anti-loose gasket body, and the end, opposite to the large anti-loose teeth, of each left anti-loose gasket body and the end, opposite to the large anti-loose teeth, of each right anti-loose gasket body closely fit the bolt cap of the bolt and the connecting pin correspondingly.

Description

technical field [0001] The invention relates to a connection structure between a wind power generator and a wind power gearbox, in particular to a connection structure between a wind power generator main shaft and a wind power gear box planetary frame. Background technique [0002] At present, there are two connection structures between the wind turbine main shaft and the wind power gearbox planetary frame, one is that the wind power generator main shaft is connected to the wind power gearbox planetary frame through a locking disc, and the other is connected to the wind power gearbox through a flange Planet carrier connection. see figure 1 As shown, a connection structure between the main shaft of the wind turbine generator and the planetary frame of the wind power gearbox that is commonly used in the market by flange connection includes a flange 1, a planetary frame 2, several paired connecting pins 3 and nuts 4- 1. The threaded body has a bolt 4 with a helix angle. The f...

AI Technical Summary

Problems solved by technology

The defect of the connection structure between the main shaft of the wind power generator and the planet carrier of the wind power gearbox in the prior art is that the bolts have no anti-loosening measures, and under the influence of the load shock and vibration of the wind power generator, the bolts may loosen, and eventually It may lead to the failure of the connection between the planet carrier and the flange and cause major safety accidents, poor safety and reliability
