Abstract

Measurement of the damage of elements in bearing can be by measuring the vibration generated in the form of a frequency signal when the pad is rotating. Measurement of vibration on the bearing by using vibration measuring instrument. Damage to the rolling bearing includes damage to the cage, outer ring, inner ring and balls. The rolling bearings used in this study are deep groove ball bearing type 6003 RS with internal diameter (d) = 17 mm, outer diameter (D) = 35 mm, bearing thickness (B) = 10, number of rolling elements (Nb) = 10 pieces, and the diameter of the rolling element (Bd) = 4.75 mm. In the rotation of the bearing (Fr) = 2003 rpm (33.38 Hz) we found the experimental results of bearings that have been damaged in the outer race at 138 Hz frequency, inner race damage at 196 Hz frequency, (ball) at a frequency of 88.8 Hz and cage damage at a frequency of 13.8 Hz.

Abstract

The recondition of the Aciera f3/07 milling machine has been done to restore the machine condition to be ready for use. The machine was damaged and caused the machine to be unable to operate and made electrical and mechanical components fail. The feasibility of the machine is tested to see the achievement of the purpose of machine reconditioning. This paper aims to see the results of the geometric testing of the machine compared with the results of running test and the vibration measurement of the machine parts. This study uses an experimental method, where damage to the machine will be identified and the damage will be immediately carried out repairs or replacement of spare parts. Furthermore, machine performance was testing including machine geometry testing, vibration testing and running test in accordance with ISO-1708 standards. The test results show that there is no significant differencebetween the results of the geometric precision testing of the machine on vibration testing and road testing. This can indicate that all three tests can be used as a reference in validating the results of machine repair, especially repairing irregularities in the geometric accuracy of the Aciera F3 milling machine.
