How are different hardness values such as Brinell hardness and Rockwell hardness converted into one another? For example, the hardness of the cycloid wheel in a cycloidal pinwheel reducer is 58–62 HRC, while the hardness of the eccentric sleeve and the output shaft is 187–229 HBS. So which one is harder or softer? How can these values be compared?
When it is greater than 20HRC, 1HRC≈10HB. When it is less than 20HRC, 1HRC≈11.5HB
Conversion tables can be found in mechanical design manuals or online
