Outer rotor vertical axis planetary gear speed increaser

Abstract

The invention discloses a vertical-axis planetary gear speed increaser for an outer rotor and belongs to the technical field of wind power generation equipment. According to the vertical-axis planetary gear speed increaser for the outer rotor, an inner hole of an output disc is connected with a positioning shaft through a first bearing, an outer circle is connected with a lower end cover through a second bearing, a dust cover is arranged on the outer circle of the lower end cover, a sun gear is arranged at the upper end of the output disc and meshed with a planetary gear arranged at the lower end of a positioning frame fixed in the positioning shaft, and the other side of the planetary gear is meshed with a gear ring arranged at the lower end of an upper end cover. The vertical-axis planetary gear speed increaser is characterized in that the lower end cover is connected with the dust cover, a sealing ring of the second bearing and the output disc to form a liquid storage device to enable the planetary gear system to be directly immersed in lubricating oil to run, noise is lowered, and service life is prolonged; meanwhile, a center shaft serves as the positioning shaft, the speed increaser is connected with a vertical-axis outer rotor electric generator through connecting holes in the transmission output disc, rotating speed is increased, and electric generating effect is improved; a center point lightning arrester can be installed on the positioning shaft, and the speed increaser of the outer rotor is innovative in terms of being directly matched with the outer rotor electric generator and the center point lightning arrester.

Description

technical field [0001] The invention relates to an outer rotor vertical axis planetary gear speed increaser, which belongs to the technical field of clean energy wind power generation equipment, in particular to an outer rotor speed increaser that can be matched with a vertical axis outer rotor wind power generator. Background technique [0002] The wind power generator speed increaser in the prior art is composed of an input shaft through the transmission output disk of the transmission gearbox. The disadvantage is that the speed increaser casing must be fixed with the generator stator casing before it can work, so it can only be used with ordinary generators. 1. The electric motor is used as a complete set. It cannot be used with the generator and motor of the outer rotor, and the central point lightning protection device cannot be installed to ensure the safe operation of the stator winding of the wind turbine. Contents of the invention [0003] The purpose of the prese...
