Method for real-time detecting bearing shell vibration by image analysis

Abstract

The invention discloses a method for analyzing and detecting bearing pad vibration by images, comprising steps as follows: (1) an image acquisition device is installed; (2) based on displayed images, the image acquisition device is fine-tuned until the image effect is the best; (3) correction is carried out on a distortion parameter of the stored images; (4) a computer works out the amplitude of bearing pad vibration by real-time identification and recording of the position of the bearing pad. The method for analyzing and detecting bearing pad vibration by images of the invention automatically record the whole process of bearing pad vibration, gives a warning when vibration amplitude exceeds safety range, shoots the bearing pad by the image acquisition device and adopts a non-contact measurement method without having to make major changes on an original mechanical device or leading detection personnel to approach the device. Compared with the traditional detection device, the invention has the advantages that the structure is simple, the cost is greatly reduced, the assembly and management is more convenient, a chart can be automatically generated, personnel can iconically observe the vibration of the bearing, and the maintenance is convenient.

Description

1. Technical field [0001] The invention relates to an image analysis method, in particular to an image analysis method for real-time detection of bearing bush vibration. 2. Background technology [0002] Bearings are an important support for shafts and other rotating components, and are one of the earliest mechanical basic components that adopt specialized mass production methods. Bearings are used in a wide range of fields, including trains and automobiles, mining machinery, steel rolling and steelmaking, aerospace and electrical machinery, etc. Bearings are divided into rolling bearings and sliding bearings. At present, rolling bearings are the most widely used. It has many advantages, such as: low friction coefficient, convenient maintenance, and simple structure. It is these advantages that make it applied in all aspects of industrial transmission. [0003] However, the bearing cannot always work stably. Due to the influence of design parameters, manufacturing errors, ...
