Thermal zinc spraying drawing force detection method of wind turbine bearing

Abstract

The invention provides a thermal zinc spraying drawing force detection method of a wind turbine bearing. A drawing force detection sample block made of the same material of the wind turbine bearing isproduced, and the detection sample block is matched with a wind turbine bearing mounting hole in shape; the drawing force detection sample block is mounted in the wind turbine bearing mounting hole;the drawing force detection sample block is subjected two sand blasting treatment with the wind turbine bearing; after sand blasting, the drawing force detection sample block is subjected to zinc spraying treatment with a product; after zinc spraying, a drawing force detection rivet is glued to the drawing force detection sample block; after a preset period, drawing force detection is conducted. The drawing force detection sample block can be processed as part of the product instead of being treated independently, the binding force condition of each set of wind turbine bearing after spraying process can be randomly detected, data are real and effective, the accuracy is high, the actual condition in the processing process can be reflected, and real-time adjustment can be performed accordingto the actual detection condition.

Description

technical field [0001] The invention relates to a method for detecting the drawing force of a wind power bearing by hot-spraying zinc, and belongs to the field of wind power bearing anticorrosion. Background technique [0002] Due to the harsh working environment and long service life of wind power bearings, there are strict requirements for the bonding force of anti-corrosion surface spraying of wind power bearings. In the past, when testing the adhesion of the sprayed surface of wind power bearings, steel plates of the same material as wind power bearings were used for thermal spraying zinc treatment, and then the pulling force testing rivets were used to test the pulling force. The testing process was purposeful and could not reach all For the purpose of random sampling and testing, it is impossible to ensure that the surface bonding force of all products is true and effective, and when the steel plate is thermally sprayed with zinc, the intensity of sandblasting, thickne...

In the past, when testing the adhesion of the sprayed surface of wind power bearings, steel plates of the same material as wind power bearings were used for thermal spraying zinc treatment, and then the pulling force testing rivets were used to test the pulling force. The testing process was purposeful and could not reach all For the purpose of random sampling and testing, it is impossible to ensure that the surface bonding force of all products is true and effective, and when the steel plate is thermally sprayed with zinc, the intensity of sandblasting, thickness of sprayed zinc, temperature and other human factors and environmental factors cannot be guaranteed to be consistent with wind power bearings. The zinc spraying treatment is exactly the same, so the detected pulling force will be different from the real pulling force of the wind power bearing, and the detection result is not accurate enough.
