gear system in grinding mill for analysis

[gear system in grinding mill for analysis]

1.4 Gear Grinding Gear Grinding is performed with a grinding wheel that removes a very thin layer of the case hardening to generate the final profile. The wheel can either be a profile grinder where the CNC motion of the wheel generates the profile or the profile can be designed into the wheel and ground onto the gear.

Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pin-ions, 3.7 MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used two4.47 MPa (6000

Operations such as shaving, gear grinding and gear honing are usually used to finish the gear surface. Often, gears have to be treated by a combination of these operations, e.g. grinding and honing. This is because gear honing operations do not remove enough stock although they do create a surface lay favorable for quiet operation.
