Therefore, the two failed O-rings ii 3 must be replaced or repaired. This requires disassembly of the guide shaft body 1. Obviously, since the guide shaft body 1 is welded to the guide shaft sleeve 2, it cannot be detached alone but can be detached together with the guide shaft sleeve 2. This necessitates the disassembly of the guide shaft cover 6 connected to the carrier 9, the O-ring seal i 7 fitted between the guide shaft cover 6 and the carrier 9, the guide shaft bearing 14 and the right end cover 15 fitted to the gear case housing 11, and the like, to disassemble the guide shaft main body 1 and the guide shaft sleeve 2, and to replace or repair the two O-ring seals ii 3. After that, the guide shaft body 1, the guide shaft bushing 2, the guide shaft end cap 6, the O-ring i 7, the guide shaft bearing 14, the right end cap 15, and the like are reassembled. In particular, once oil seeps inside the guide shaft, the guide shaft cannot be independently disassembled and maintained, and only the wind power gear box can be integrally replaced. It can be seen that such conventional wind power gearbox guide shaft seal arrangements are difficult and costly to maintain.
