The bearing is so hard, how is the bead stuffed? After reading it, I understand it

A variety of parts are commonly used in modern machinery and equipment, that is, bearings, its main function is to support the mechanical rotating body, reducing the friction coefficient during its movement, the bearing is divided into sliding bearing and rolling bearing, sliding bearing radial The size, vibration and noise are large, the cost is relatively high, and the rolling bearing is more widely used. The rolling bearing is generally composed of the outer ring, the inner ring, the rolling element and the cage. If it is stricter, the seal and the lubricating oil should also be counted.  This is the six major parts.

Hardness is the most important quality characteristic of a bearing. It has an important influence on the contact fatigue strength, wear resistance and elastic limit. Then, how does the seemingly integrated bearing put the beads into it? What is the assembly order of it? I believe many people are very confused about this issue, and now YuKi group will give you a answer. In fact, this principle is very simple. When the number of beads in the bearing is relatively small, the inner and outer rings are generally used. The outer ring is placed on the inner ring, and the two sides meet at the other side. Space, so that you can insert the beads one by one from the largest space, then move the position of the inner ring to the center, and then use the cage to fix, so that a rolling bearing is ready.

However, we have also seen the kind of bearings that are full of beads. In the face of such bearings, the above assembly method seems to be not suitable, then how is it done? In fact, when the beads need to fill the entire bearing, the outer ring usually has a ball-shaped gap. From this gap, the beads are put in, and then the gap is sealed, so that a bearing can be easily assembled. When designing such a bearing, of course, this problem has already been considered, but this bearing also has its disadvantages, that is, the ability to withstand radial loads is relatively small.

Many mechanical processes make people feel very magical. Each of their programs has its own unique order. It doesn't matter if a small part is the key to the success of the whole machine. Even when constructing such small parts, it will even It is more difficult than designing and assembling the entire machine. Ok, have we explained the doubts of everyone?
