A kind of part is commonly used in various modern mechanical equipment, that is, bearing. Its main function is to support the mechanical rotating body and reduce the friction coefficient during its movement. Bearings are divided into sliding bearings and rolling bearings. The radial dimension, vibration and noise of sliding bearings are large, and the cost of rolling bearings is relatively high. More widely used, rolling bearings are generally composed of outer rings, inner rings, rolling bodies and cages. If more stringent, sealing and lubricating oil should also be included, which is the six major parts.
Hardness is the most important quality characteristic of bearings. It has an important impact on contact fatigue strength, wear resistance and elastic limit. So how does a bearing that looks like an integral whole put beads in it? What is its assembly sequence? I believe that many people are very confused about this issue, this edition will give you an answer. In fact, this principle is very simple. When the number of beads in the bearing is relatively small, it is generally used to complete the inner and outer rings. When the outer rings are above the inner rings, there will be a lot of space on the other side, so that beads can be inserted one by one from the largest space, and then moved. Moving the inner ring to the center, and then use the cage to fix, such a rolling bearing is ready.
But we have also seen the kind of bearings full of beads, in the face of such bearings, the above assembly method seems not very suitable, then how is it done? In fact, when the beads need to fill the whole bearing, the outer ring usually has a collision gap, from which the beads are loaded, and then the gap is encapsulated, so that the bearing can be easily assembled. People have already considered this problem when designing this kind of bearing, of course, but this kind of bearing. Bearing also has its disadvantage, that is, the ability to withstand radial load is relatively small.
Many mechanical processes make people feel particularly amazing, each of their procedures has its own unique order, not to mention a small part, may be the key to the success of the whole machine, and in the construction of such small parts, even more difficult than the design and assembly of the whole machine, to see these assembly processes, Xiaobian just want to The wisdom of human beings is endless. Well, that's all for this issue. Have we explained your doubts clearly? If you have any questions, you can leave a message below.
