I will easily and simply explain what tolerances and landings are. Every novice specialist will understand in general terms. You will understand the basics, and if you want to study in more detail, continue watching my videos.
What are tolerances and fits for dummies? In simple terms, I will talk about tolerances and landings in a few minutes. In the technical school, on the subject of standardization, we passed tolerances and landings of shafts and holes according to dull pictures and books. Using such materials, it is not easy to study tolerances and fits on drawings, especially if you have no idea what it is. Moreover, there are several varieties, for example, interference fit, clearance fit, transitional fit and sliding fit. Tellingly, in the production drawings, the dimensional tolerance is indicated immediately in numerical values. Therefore, when working in a production shop, the question of how to choose a dimensional tolerance usually does not arise. But do not forget that there is also a shaft system and a hole system, depending on which you need to choose the tolerance number. Yes, what can I say, tolerances and landings in mechanical engineering are a very slippery and complicated topic, but if you figure it out, there is nothing complicated about it. But remember that the transition fit in the shaft system is different from the hole system. But you can determine the landing tolerance not only according to the tables from GOST, but also according to the proposed program. In this video I will talk about tolerances and landings for beginners in mechanical engineering. And then the tolerance on the drawing will be clear and simple.
