PENGURANGAN CACAT LENTUR PADA POROS TRANSMISI AKIBAT PENGERASAN PERMUKAAN DENGAN PROSES KARBURASI GAS

The persisting problem of bending defect on the transmission shaft of the Perkasa bus manufactured by PT Texmaco Subang is shown by the changes of the run out following the carburizing process. The bending defect could lead to fatigue failure that lowered the shaft life time. The research was carrie...
