First, the main function of the rolling bearing: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Under the condition of ensuring the bearing has a satisfactory life; to support the rotating (or swaying) parts; to transfer the load; to reduce the conflict between the moving pairs; to make it rotate (or swing) sensitive.
Second, the fundamental needs of bearings:
Satisfied with the load, speed, accuracy, dynamic function (noise, oscillation), ambient temperature and service life required for the operating conditions.
Third, the basic layout of the rolling bearing:
It consists of inner ring, outer ring, rolling body and cage (commonly known as four large pieces).
The inner ring is mounted with the shaft and the outer ring and the bearing housing hole. When the inner ring or the outer ring is a rotating ferrule, the tight cooperation is used; when the inner ring or the outer ring is not rotated, the transition cooperation is selected.
The roll body (steel ball, roller or needle roller) is the central part of the roll bearing; when the inner and outer rings are relatively changed; the roll body rolls between the raceways of the inner and outer rings. The shape, size and number of the roll body directly affect the bearing. Load ability and use function.
The cage can evenly distribute the roll body, guide the rotation of the roll body and improve the smooth function inside the bearing.
