Wind power gear box

Abstract

The invention provides a wind power gear box. The wind power gear box comprises a front tank, a rear tank, a planet gear transmission mechanism and a parallel shaft transmission mechanism. The planetgear transmission mechanism comprises a first-stage planet gear train and a second-stage planet gear train. The first-stage planet gear train comprises an input shaft, a compound planet carrier, a compound double planet gear, a long planet gear shaft, a compound planet gear, a short planet gear shaft, an inert sun gear, a first-stage sun gear and a first-stage inner gear ring. The compound doubleplanet gear comprises a small planet gear body and a large planet gear body. The small planet gear body and the compound planet gear are in engaged transmission with the inert sun gear and the first-stage inner gear ring, and one way uniform loading is achieved; and the large planet gear body and the first-stage sun gear are in engaged transmission, and another way uniform loading is achieved. Thesecond-stage planet gear train comprises a second-stage sun gear, a second-stage inner gear ring, a flange, a second-stage planet gear and a planet gear shaft. According to the wind power gear box, multi-stage planet row unbalance loading can be suppressed, and system transmission is steadier.

Description

technical field [0001] The invention relates to the technical field of wind power generation testing equipment, in particular to a connector used for a wind power generator gearbox test bench. Background technique [0002] At present, as a relatively fast-growing wind power technology, it has gradually entered the vision of various countries. As a clean and renewable energy source, wind power has been included in the national long-term energy development strategy of various countries. A wind turbine is a device that realizes wind power generation. [0003] However, since wind turbines are usually installed at tuyeres such as high mountains, wilderness, and islands, the wind power gearbox often bears the wind force of irregularly changing loads. Under the harsh conditions of strong impact and variable load, the distribution of power transmitted by the various planetary wheels of the planetary row is uneven, the load between the teeth fluctuates violently, and the phenomenon ...

AI Technical Summary

Problems solved by technology

Under the harsh conditions of strong impact and variable load, the distribution of power transmitted by the various planetary wheels of the planetary row is uneven, the load between the teeth fluctuates violently, and the phenomenon of partial load is serious, resulting in vibration and noise in the system, and the transmission is not stable, which greatly affects service life of the transmission system
