What we see every daySlewing bearing, But do we understand the structure of the composition? Below, our slewing bearing manufacturer will introduce to us. The slewing bearing is generally composed of four basic parts: inner ring, outer ring, rolling body and cage (commonly known as the "four major pieces", according to the actual Sometimes the use environment must have lubrication). The inner ring is generally assembled on the shaft and rotates simultaneously with the shaft. The outer ring is usually installed in the bearing housing or mechanical part housing, which can play a supporting effect. However, in some applications, the outer ring rotates, the inner ring is fixed, or both the inner and outer rings are rotating; at the same time, there are more types of component parts; of course, there are also those without cage, without inner ring, and without outer ring, etc. .
In thrust bearings, the ring that cooperates with the shaft is called the shaft ring, and the ring that matches the bearing seat or the shell of the mechanical part is called the seat ring.
The surface on the ring on which the rolling body rolls is generally called the raceway, and the raceway of the ball bearing is also called the raceway. The tumbling body rolls between the raceways of the inner ring and the outer ring. The structure of the tumbling body generally has the shapes of balls, cylindrical rollers, needle rollers, tapered rollers and spherical rollers. The size and quantity of the tumbling body directly affect the bearing effect of the bearing.
The effect of the cage is to separate a set of tumbling bodies in the bearing at equal distances, separately holding the tumbling bodies, or forming a combination with the inner ring or the outer ring, and guiding the tumbling bodies to move on the correct trajectory, thereby improving the bearing The internal load distribution and lubrication function, compared with a full complement ball or roller bearing without a cage, one of the differences between the two is that the friction resistance of the caged bearing is smaller, and it is more suitable for high-speed rotation.
