Abstract

The invention discloses a wind power speed increasing box which comprises a box body, an input gear shaft, a plurality of duplicate gears and a plurality of output gear shafts, wherein all of the input gear shaft, the duplicate gears and the output gear shafts are mounted in the box body; the input gear of the input gear shaft is connected with first gears of duplicate gear shafts; secondary gears of the duplicate gear shafts are connected with output gears of the output gear shafts. The wind power speed increasing box can be connected with a plurality of external power generators and is simple in structure.

Description

technical field [0001] The invention relates to a gear box, in particular to a wind power increasing gear box. Background technique [0002] The wind power gearbox is the core component used in the wind power generating set to transmit power and convert the high torque and low speed kinetic energy input by the wind wheel into low torque and high speed kinetic energy to match the generator demand. There is an existing wind power speed-up gearbox, which includes an organic base, an input shaft, an inner ring gear, a double gear, a sun wheel or a third-stage speed-up gear pair. 3 to 6 double gears are evenly distributed on the frame connected with the machine base. The double gears are connected by the shaft gears to the transmission gear grooves. There are two identical intermediate wheels between the inner ring gear and each shaft gear, forming two gears. The flow is split, and the transmission gear meshes with the center wheel, so 6-12 split flows are formed from the inner ...
