Bearing replacement rules
The post Bearing code is represented by letters (or numbers)
Preparation rules of post code
The post code is placed to the right of the basic code and is half a Chinese character away from the basic code (except for the symbols "-" and "/" in the code). When many items are changed, there are multiple groups of post codes, which are arranged from left to right;
If the content is changed to 4 groups (including 4 groups), use "/" in front of its code to separate it from the previous code;
Change the content to the two groups after group 4. When the meaning of numbers or words in the codes of the former group and the latter group may be confused, there is a space of half a Chinese character between the two codes.
Bearing configuration
A shaft often needs two fulcrums, that is, two sets of rolling bearings. The bearing configuration just solves the problems of how the bearing on the fulcrum axially fixes the shafting and how to avoid jamming after thermal expansion. Let's explain the relevant knowledge of bearing configuration.
Before configuration, be sure to understand some key points related to bearings:
① Expansion and contraction of shaft caused by temperature change.
② Bearing installation and disassembly are difficult and easy.
③ Inclination of inner ring and outer ring caused by shaft deflection and installation error.
④ Preloading method of the whole rotating system including bearing.
⑤ Bearing Bear and transfer the load at a suitable position.
