The Idling gear checkout equipment is Klingberg Gear Btesting Center and tooth width of 24.3,The hardness of the product is required to be ≤230HB, there are many hardness classification, among them, brinell hardness is determined by the depth of indentation plastic deformation hardness index.

Under certain conditions, HB and HRC can be interchanged by table lookup. Its mental calculation formula can be roughly written as: 1HRC≈10HB.

Brinell hardness

Brinell hardness (HB) is generally used when materials are soft, such as non-ferrous metals, steel before heat treatment or after annealing. Rockwell hardness (HRC) is generally used for materials with high hardness, such as hardness after heat treatment and so on.

Brinell hardness (HB) is a certain size of the test load, a certain diameter of hardened steel ball or carbide ball pressed into the surface of the metal to be measured, keep the specified time, and then unloaded, measured surface indentation diameter. The Brinell hardness number is the quotient of the load divided by the surface area of the indentation sphere.
