Spherical roller bearing tapered roller bearing shaft concentricity 30Some shafts need to ensure great coaxiality. What kind of bearings should be used? Is the following figure reasonable?Also ask the vast numbers of netizens popular science, and points are not much, thank you very much!
In the thrust ball industry, the tapered roller fit ensures that the thrust ball is radially loaded and that the tapered roller can be automatically aligned. If the load is large, the thrust ball is changed into rod bearing. Aligning bearings are aimed at different shafts of the bore and are placed at one end rather than both ends. I don't know if you use it for reference only.
To ensure that the workpiece processed (in line with the requirements of surface roughness; not cylindricity and so on, not only the technical requirements) is to ensure that the lathe spindle "Park beat a parameter; in addition to ensure the parameters more.......Otherwise, the enterprises that make lathes have long been eliminated by such an ambitious personage like you! ......
First of all, choose "C" precision bearings (B class accuracy is highest, I do not know whether the current national standard); secondly, according to your shaft load to decide. Can not use self-aligning bearings, you can consider "tapered roller bearings."".
