Rolling bearing is running between the shaft and the shaft seat sliding friction into rolling friction, thereby significantly reducing friction loss of a precision mechanical components.
In addition to have special design and process performance requirements, for most of the rolling bearing, its structure is very simple.
As shown in figure 1 -
1, generally from the diagram, the outer ring, rolling body and cage, commonly known as the 'four big' including ball and roller in children.
This is the basic structure of the rolling bearings.
As for bearing the gradual improvement of the product life, reliability requirements, many bearing design and manufacture of experts and scholars at home and abroad agree that lubricant is also a big of rolling bearings, the rolling bearing is composed of the 'big five'.
This is a new perspective.
Sometimes on bearing performance requirements are different, the structure also has a lot of differences.
Some bearing without inner ring or outer ring or no inside and outside the ring at the same time;
Some bearing dust cover, seal, and when to install is the use of stop pad diagram, set set of and parts such as screws.
Between groups inside and outside figure roller rolling, and carry and transmit load.
Cage separates rolling body evenly, in order to avoid they collide with each other, and guiding their normal movement, prevent them from loss and improve the internal bearing lubrication, and other functions.
In the thrust bearing, and axis fitting ring is called axis (
Tight)
Circle, with the ring with suitable or mechanical bearing shell hit (
Live)
Ring, shaft ring and seat generally referred to as the gasket
