Slewing bearings are still relatively common in our lives, so do you understand its basic structure? Below, our slewing bearing manufacturers will introduce to you. Slewing bearings are generally composed of inner ring, outer ring, rolling body and cage. Basically composed of several parts (commonly known as the "four major parts", depending on the actual use environment, sometimes there must be lubricants). The inner ring is generally assembled on the shaft and rotates with the shaft. The outer ring is generally installed in the bearing housing or mechanical component 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 the thrust bearing, the ring that cooperates with the shaft is called the shaft ring, and the ring that matches the bearing seat or mechanical part shell is called the seat ring.
The surface on the ring for the rolling body to roll 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 number of tumbling bodies directly affect the bearing capacity of the bearing.
The effect of the cage is to separate a set of rolling bodies in the bearing at equal distances, to hold the rolling bodies alone or to form an assembly with the inner or outer ring, and to guide the rolling bodies to move on the correct track, thereby improving the bearing The internal load distribution and lubrication performance, compared with a full-filled 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.
