locking of mixed bearings (obliques or conical rollers)

[Branda]

hello to all, I am a mechanical student at the first year who is attending the drawing course of machines. I need a tip about locking the mixed bearings. I have not been able to understand how the bearings must be blocked according to the type of assembly you have (e.g. x or o). would you kindly explain how the two rings (in and out) must be blocked?

you should ask your teacher who will certainly benefit in a vis-à-vis explanation

Unfortunately I do not have the opportunity to meet him because I am away and in a few days I will have the exam. I asked you for this, otherwise I would meet with him.

on bearing builder sites (e.g.Skf) find examples of mounting, look at those, a design is worth more than a thousand words, once you have an idea, it is easier to clarify any doubts.

besides the site skf and ina that explain everything with drawings, there are textbooks.
Moreover on the forum the topic has already been dealt with.
bearings are always composed of an external track, an interior and a system of rollers or spheres. It is easy enough to understand what happens if you push on one side or another.
If you just irreparably can't understand....maybe it is the case of repeating the exam, because in the context of the work there is need prepared people and if you don't have to bang it otherwise it is out.

many sites disclose information about it, such as these:

Good evening, you should consult the manufacturer's catalogue. in the pages where there are the size and features there are the patterns of how they should be blocked. You usually have the bearing mounted and handled or in griglio the shoulders that block the slopes. in these figures there are then references with quotas in letters that recall the tables of the catalog and are the diameters of the shoulders that you must respect. example radial ball bearing with protection screens. This bearing has two steel tracks with inside the spheres. between the two tracks on the outside are mounted two anti-dust seals that are not of metal but say plastic for simplicity, as the spacers or flanges that must block the two slopes must be of steel you do not have to touch these two seals otherwise destroy the bearing. In the tables you will find the minimum diameter of the external track to draw the spacer or flange, the same for the internal track you will find the maximum diameter . These two values must be respected in order to make the bearing work properly without problems. this applies to all ball bearings as well as axial or radial rollers.
