The invention relates to a large-power wind driven generator step-up gearbox with an electric barring device. The large-power wind driven generator step-up gearbox comprises a large-power wind driven generator step-up gearbox, wherein a large barring gear, a small barring gear shaft and a box body of a clutch device are arranged on a high-speed end bearing seat; a driving motor is fixedly mounted on the box body of the clutch device; the large barring gear is meshed with the small barring gear on a small barring gear shaft; a clutch mechanism is fixedly mounted on the small barring gear shaft and the output shaft of the driving motor; the clutch mechanism comprises an outer spline shaft sleeve, an inner sliding spline combination shaft sleeve, a combination shaft sleeve, shifting fork rods and a shifting rod shaft; the combination shaft sleeve sleeves the small barring gear shaft; the inner sliding spline combination shaft sleeve is matched with the outer spline shaft sleeve; end surface teeth are formed in match on opposite sides of the combination shaft sleeve and the inner sliding spline combination shaft sleeve in the clutch mechanism; the end surface teeth matched with the inner sliding spline combination shaft sleeve are driven by the shifting fork rods to be separated or meshed in a tooth embedding manner.
Description
technical field [0001] The invention relates to a speed-increasing gear box of a wind power generator, in particular to a speed-up gear box of a high-power wind power generator equipped with an electric barring device. Background technique [0002] With the rapid development of the wind power industry, low-power wind turbines have gradually failed to meet market demand. Various wind turbine manufacturers have begun to develop high-power wind turbines, and high-power models such as 5MW to 6MW have begun to appear on the stage. Existing high-power wind turbine speed-up gearboxes generally adopt a two-stage planetary gear train and a final-stage parallel shaft speed-up structure. They are large-scale gearboxes, and their overall weight is generally more than 50 tons, of which the 6MW main gearbox The weight is more than 60 tons, plus the weight of the main shaft and hub, such a large weight of the transmission chain brings great difficulties to the early installation and later ...
