Large-size wind power gear box

Abstract

The invention provides a large-size wind power gear box. The large-size wind power gear box can adopt a special fixture to conduct machining on a horizontal machining center, the number of machining parts is large, and the machining precision is high, the problem that a front bearing hole I, rear bearing hole I' and the like are unqualified due to offset generated in the dismantling process is particularly solved, and the large-size wind powder gear box further comprises four supporting structures (60, 61) each comprising a supporting column (60) and a supporting part (61) extending outwards from the bottom end of the supporting column horizontally. The supporting columns (60) of two of the supporting structures are connected to the bottoms of the two sides of the periphery of a rear box (51) on the front portion of the large-size wind powder gear box and extend out perpendicularly and downwards, and the supporting parts (61) extend horizontally forwards, crude positioning holes (62) are formed in the supporting parts; and the supporting columns (60) of the other two supporting structures (60, 61) are connected to the bottoms of the two sides of the periphery of a middle box (50) on the rear of the large-size wind power gear box, and extend downwards perpendicularly, and the supporting parts (61) extend backwards horizontally.

Description

technical field [0001] The invention relates to a wind power gear box, in particular to a large wind power gear box. Background technique [0002] see Figure 1 to Figure 4 As shown, a common large-scale wind power gear box includes a rear box 51 and a middle box 50 assembled front and rear, and a rear box cover 53 assembled on one side of the rear box 51, wherein the rear box 51 is a The front end and one side are open box bodies with openings; the middle parts of the middle box body 50 and the rear box body 51 are respectively provided with a coaxial front bearing hole I52 and a rear bearing hole I'52'52' corresponding to the front and rear. On one side of the box body 50 and corresponding to the rear box cover 53 , there are coaxial front bearing hole II 54 and front bearing hole II 54 ′ that pass through the front and back respectively. Due to the large size and heavy weight of the large-scale wind power gearbox, and the two groups of bearing holes, the front bearing ho...

Problems solved by technology

Therefore, there are many processing steps, and the processing accuracy is difficult to guarantee; meanwhile, the handling, disassembly and reassembly of the middle box body 50, the rear box body 51 and the rear box cover 53 are not only time-consuming and laborious, but also prone to deviation during the disassembly process, resulting in the front bearing Hole I52 and rear bearing hole I'52', front bearing shaft hole II and front bearing shaft hole II' are not easy to pass the machining
