The gearbox comprises a
machine body, a supporting rod is installed at the bottom of the
machine body, a rotating cover is rotationally connected to the side end of the
machine body, fan blades are installed in the rotating cover, a partition plate is installed at the bottom of the inner wall of the machine body, and a driving motor is installed at the upper end of the partition plate; a transmission shaft is installed at the output end of the driving motor, a gearbox is installed in the middle of the transmission shaft, and a ventilation
pipe is connected between the driving motor and the inner wall of the machine body. Through the arrangement of the mounting frame, the gear ring, the
extrusion ring, the scraping plate, the closing plate, the electric push rod A and the cleaning adsorption mechanism,
scrap iron on the surface of the
filter element can be adsorbed, the problem that the
filter element is blocked by the
scrap iron is avoided, and therefore circulation of engine oil in the gearbox of the
wind driven generator can be ensured; the problem of overheating of equipment caused by temperature rise due to unsmooth flowing of internal engine
oil can be avoided, and insufficient
lubrication and overheating of the interior of the gearbox of the
wind driven generator can be prevented.
