Embodiment Construction

[0035] The present invention will be further described below in conjunction with specific examples.

[0036] As shown in Table 1 below, the detection and adjustment records of the Xiangyang wind field and the Hongnijing wind field are given.

[0037] Table 1 Detection and adjustment records of Xiangyang wind field and Hongnijing wind field

[0038]

[0039] It can be seen from the above table that the verticality between the main shaft and the end cover installation surface of all oil-leaking fans is very large, such as Hongnijing 22# and 11#, which meet the requirements after adjustment, while the other three such as Xiangyang 98# 17# and 56# red mud wells do not need to be adjusted because the angle between the main shaft and the end cover installation surface is small and there is no oil leakage. Therefore, the main reason affecting the oil leakage of the main shaft sealing ring and the early wear of the 530 bearing is whether the verticality between the main shaft and ...

Abstract

The invention discloses a method for centering and adjusting a mainshaft bearing shafting of a wind generating set. Adjusting bolts on an elastic support of a gearbox are adjusted, the perpendicularity between a mainshaft and an end cover mounting surface is controlled in a range of 90 degrees-90 degrees 10 minutes, and a centering angle of a bearing is in an ideal angle value range, so that the mainshaft bearing works in a reasonable radial internal clearance, problems of oil leakage of a seal, temperature rise and premature wear of the mainshaft bearing of the wind generating set are effectively solved, operation and maintenance cost of a wind power plant is greatly reduced and the effect is obvious.

Description

technical field [0001] The invention relates to the technical field of centering of a main shaft bearing of a wind power generating set, in particular to a method for adjusting the centering of a main shaft bearing of a wind generating set. Background technique [0002] At present, wind power generation, as an environmentally friendly energy industry, is getting more and more attention in the modern energy-constrained society, and the investment in wind power generators is also increasing. At present, the main shaft bearings of wind power generators generally adopt self-aligning bearings. The maximum alignment angle of the bearings is 0.5°. Due to the machining errors of the components that make up the shaft system, a unified assembly adjustment method is adopted during assembly in the workshop. As a result, the main shaft bearings of some fans deviate from their self-aligning angles, which will cause problems such as early wear of the bearings, oil leakage, and temperature ...
