Embodiment Construction

[0008] The accompanying drawing discloses a non-limiting structural diagram of a specific embodiment involved in the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.

[0009] Depend on figure 1 It can be seen that the embodiment of the present invention includes a flange 1, a middle box body 2 and a rear box body 3, and between the flange 1 and the middle box body 2, a first-stage and second-stage ring gear group 4, a third-stage ring gear group, and a third-stage ring gear group are arranged. 5. There is a fourth-stage internal gear 6 between the middle box 2 and the rear box 3. At the same time, the first and second-stage internal gears 4, the third-stage internal gear 5, and the fourth-stage internal gear 6 As a gearbox case, the flange 1, the first and second-stage internal ring gears 4, the third-stage internal ring gear 5, the middle case 2, the fourth-stage internal ring gear 6 and the rear case ...

Abstract

The invention relates to a kind of off-course gear box of wind-driven generator. Between the flange and the middle box body there are the first-grade and the second-grade inner gear cluster, and the third-grade and fourth-grade inner gear circles. On the first and the second grade inner gear cluster there are inner gear circles. Input shaft, planet frames and solar wheels at all levels, output gear shaft axis, the input shaft of connected to the first-grade solar wheel, the planet frames at all levels are connected to the next grade solar wheel. The fourth grade planet frame is fixed on the back box body by the bearing. The end of the frame goes through the back box body and connects with the output gear. Each-grade planet frame has planet wheel, between the input shaft and flange, between the fourth grade planet frame and back box body, there is oil-sealing. Advantages of the invention: take the first and second inner gear circule cluster as a component and make the structure compact; take the gear circle cluster and the inner gear circles at all levels, as a part of the box, reduce the weight, and it is easy to process, convenient to dismantle and fix.

Description

technical field [0001] The invention relates to a gear box, in particular to a yaw gear box of a wind power generator. Background technique [0002] Compared with traditional thermal power generation, the use of wind power generation has the advantage of no pollution to the environment. Compared with hydropower generation, it has the advantages of low infrastructure cost, small footprint, and convenient maintenance. For large hydropower stations, water storage The library is also prone to certain security risks downstream. In wind turbines, the yaw gearbox is a special gearbox for wind turbines to align or deviate from the wind direction. Due to the compact structure and high reliability requirements of the yaw gearbox, the yaw gearbox used in wind turbines currently used in my country It is mainly solved by imports. The output shaft of this yaw gearbox is prone to oil leakage during use. Contents of the invention [0003] The purpose of the present invention is to provid...
