Abstract
The invention provides a method for quickly detecting a damaged bearing. An inner ring and an outer ring of a bearing are all provided with two ultrasonic echo baffle plates; each baffle plate is connected to a noise ultrasonic detector arranged outside the bearing; and the noise ultrasonic detector can quickly detect noise values of the inner ring and the outer ring; and when one noise value is abnormal, the noise ultrasonic detector detects noises of various points by slowing down the rotating speed to quickly judge the damage or a position where an impurity is positioned; therefore, the method for quickly detecting the damaged bearing is realized. The method has the remarkable advantages that: the inner and outer rings of the bearing are provided with the ultrasonic echo baffle plates; the noise ultrasonic detector can quickly detect the noise values of the inner and outer rings; and when the values are abnormally jumped, the bearing is worn or the impurity enters the bearing, and the bearing is required to be replaced or treated; therefore, the problems of the bearing can be timely discovered, and the service life of the bearing can be prolonged.
Description
Technical field
The present invention relates to a kind of bearing detection method, especially a kind of method for quick of damaged bearing.
Background technology
Bearing is the fixed member in the machinery.When other parts produce relative motion each other on axle, be used for retainer shaft the center and control the parts of this motion, just be referred to as bearing.
Study carefully it and be used for saying be to support, promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also can be understood as it and be used for fixing axle.Be exactly that stationary shaft makes it can only realize rotating, and control its moving axially and radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle may be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission, must realize good lubricating in order to reduce this influence on the bearing of high speed shaft, the bearing that has itself has had lubricated, is called prelubricated bearing, and most bearing must have lubricating oil, be responsible for when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that sliding friction is changed into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Under certain loading, revolution that bearing is experienced before spot corrosion occurring or hourage are called bearing life.Since manufacturing accuracy, the difference of material degree of uniformity, even same material, the same a collection of bearing of same size uses under same condition of work, its life-span length is also inequality.For determining the standard of bearing life, bearing life and reliability are connected.
But bearing is had relatively high expectations to its precision and quiet performance as a kind of accurate industrial devices, and the explanation bearing has had wearing and tearing largely when generally appearing at big noise, just is not suitable for continuing using for the bigger occasion of accuracy requirement again.
Summary of the invention
At the problems referred to above, the invention provides a kind of method for quick of damaged bearing.
A kind of method for quick of damaged bearing, it is characterized in that on the inner ring of bearing and outer ring, being provided with two ultrasound wave echo baffle plates, each baffle plate all is connected to and is arranged on the outer noise ultrasound measuring instrument of bearing, the level of noise that can fast detecting goes out Internal and external cycle, one of them noise occurs when unusual, can detect the noise of each point by the rotating speed that slows down, judge damaged fast or infiltrate the position of foreign material, form a kind of method of fast detecting damaged bearing.
Remarkable result of the present invention is to be provided with ultrasound wave echo baffle plate on the Internal and external cycle of bearing, can measure the level of noise of Internal and external cycle fast by the noise measuring instrument, when beating unusually appears in its numerical value, just illustrate that bearing has wearing and tearing or infiltrates foreign material, need change or handle, so just the problem of bearing can be in time found, and its serviceable life can be prolonged.
Embodiment
Below the present invention will be further described: on the inner ring of bearing and outer ring, be provided with two ultrasound wave echo baffle plates, each baffle plate all is connected to and is arranged on the outer noise ultrasound measuring instrument of bearing, its energy fast detecting goes out the level of noise of Internal and external cycle, when wherein noise occurs when unusual, illustrate wherein to occur damaged or infiltrate foreign material, the rotating speed of bearing that can slow down this moment, and detect the noise of each point once more, the unusual position that raises of noise appears, and damaged exactly or infiltrate the position of foreign material.
Apply the present invention in the mechanical system, on the Internal and external cycle of bearing, be provided with ultrasound wave echo baffle plate, can measure the level of noise of Internal and external cycle fast by the noise measuring instrument, when beating unusually appears in its numerical value, just illustrate that bearing has wearing and tearing or infiltrates foreign material, need change or handle, so just can in time find the problem of bearing, and can prolong its serviceable life, be particularly useful for the precision of bearing is had the occasion of high requirements.
Claims (2)
1. the method for quick of a damaged bearing, it is characterized in that on the inner ring of bearing and outer ring, being provided with two ultrasound wave echo baffle plates, each baffle plate all is connected to and is arranged on the outer noise ultrasound measuring instrument of bearing, the level of noise that can fast detecting goes out Internal and external cycle, one of them noise occurs when unusual, can detect the noise of each point by the rotating speed that slows down, judge damaged fast or infiltrate the position of foreign material, form a kind of method of fast detecting damaged bearing.
2. the method for quick of damaged bearing as claimed in claim 1 is characterized in that being provided with two ultrasound wave echo baffle plates on the inner ring of bearing and outer ring, and each baffle plate all is connected to and is arranged on the outer noise ultrasound measuring instrument of bearing.
