A NEW SUGAR MILL DRIVE COUPLING SASTA

The coupling generates no radial load other than its own mass acting on the shafts. (ii) Sugar-mill top-rolls are capable ofjournal misalign­ ment up to 32 mm, but under good operating condi­ tions would seldom be more than 10mm misaligned. This misalignment can only be in the vertical plane, and it is only when the mill roll is misaligned sloping

Failure analysis of rolling mill stand coupling

01/11/2014· The actual service life of couplings is estimated from the mill production and rolling schedule. The service life of the couplings is divided into the sequences depending of roll wearing. The roll service life before machining due to wearing was estimated after 4000 rolling tons of steel (about 15 working days or about 17,390 rolled billets). After that period, the rolls should be replaced and machined on new working dimensions. The couplings
