UNA rodamiento de rodillos cruzados is a special type of bearing in which the inner ring is divided and the outer ring rotates. Compared with conventional models, the rigidity of crossed roller bearings is increased by 3 a 4 veces. Al mismo tiempo, since the inner ring or outer ring of the crossed roller bearing is divided into two structures, the bearing clearance can be adjusted, and even if a preload is applied, high-precision rotational motion can be obtained.
En nuestra vida diaria, the bearing will encounter the problem of abnormal bearing noise after three or two years of normal use. The following are several methods for detecting abnormal noise of bearings summarized by crossed roller bearing manufacturers. Vamos a ver.
Cause of abnormal noise
There are many kinds of abnormal sounds during the operation of crossed roller bearings, the formation mechanism is relatively complex, and the factors are multi-faceted, and various abnormal sounds are often superimposed together, which is difficult to distinguish. The main reasons are as follows:
(1) There are periodic vibration pulses caused by bumps, arañazos o defectos graves en las pistas de rodadura interior y exterior del rodamiento.
(2) Pulsos de vibración no periódicos causados por defectos tales como golpes y rasguños en la superficie del elemento rodante.
(3) Pulsos de vibración periódicos o aperiódicos causados por la presencia de polvo de hierro residual adsorbido magnéticamente en caminos de rodadura o elementos rodantes.
(4) El pulso de vibración aperiódica causado por las impurezas o el polvo que ingresa al área de funcionamiento de la pista de rodadura del rodamiento..
