Detection and maintenance method for self-aligning roller bearing of spindle of wind driven generator and jacking tool

Abstract

The invention discloses a detection and maintenance method for a self-aligning roller bearing of a spindle of a wind driven generator. The detection and maintenance method includes steps that: 1 an end cover of the self-aligning roller bearing is opened for oil cleaning; 2 the axial position of an outer ring of the self-aligning roller bearing is detected; 3 the outer ring is axially adjusted according to the detection result of the step 2; and 4 oil is supplemented, the end cover and an oil leakage bend are installed, and detection and maintenance are completed. The detection and maintenance method for the self-aligning roller bearing on the spindle of the wind driven generator and a jacking tool are designed for the condition of dislocation of an inner ring and the outer ring of the self-aligning roller bearing on the spindle of the wind driven generator.

Description

technical field [0001] The invention relates to a detection and maintenance method and equipment, in particular to a detection and maintenance method of an automatic self-aligning roller bearing on a wind power generator main shaft and a wind power generator main shaft jacking tool used in the detection and maintenance method. Background technique [0002] See figure 1 , figure 2 with image 3 , The fan main shaft 1 is equipped with an automatic self-aligning roller bearing 2 (hereinafter referred to as 670 bearing) on ​​the side close to the hub, and the fan main shaft 1 is also equipped with another self-aligning roller bearing 3 (hereinafter referred to as 530 bearing). [0003] Since the beginning of 2012, several wind farms of our company have started to report the problem of excessive temperature rise of the self-aligning roller bearing (hereinafter referred to as 670 bearing) of model 670 on the main shaft of the wind turbine. The problem is imminent and must be so...

Problems solved by technology

[0003] Since the beginning of 2012, several wind farms of our company have started to report the problem of excessive temperature rise of the self-aligning roller bearing model 670 (hereinafter referred to as 670 bearing) on ​​the main shaft of the wind turbine. The problem is imminent and must be solved, otherwise, There is a risk that our fan may be returned by the owner, and at the same time bring a lot of hoisting and transportation costs and negative effects

[0004] In order to solve this problem, from April 2012, our company urgently dispatched relevant technical personnel to the wind farm site and notified the relevant technical personnel of ZWZ to board the plane for on-site analysis. By July 2012, our technical department, The quality department and ZWZ technicians have arrived at the Heijiazhuang wind field in Shanxi, the Langergou wind field in Shaanxi, the Taiyangshan wind field in Ningxia, the Wujiangyuan wind field in Guizhou, the Dianbairudong wind field in Guangdong, and the Zhongao wind field in Maoming, Guangdong. In the wind field, the fans with 670 bearing temperature rise problems were inspected and analyzed, local adjustments and refueling treatment were carried out, and multiple inspection and analysis reports were issued, and the 670 bearing temperature rise problems caused by multiple fans in the wind field were obtained. Relevant data, put forward the basic idea to solve the problem of temperature rise of 670 bearings, but all these works did not find a specific solution to the problem of temperature rise of 670 bearings
