Abstract

Damage to engine part from unit of heavy equipment that often happens will interfere the activity of production because the unit of heavy equipment automatically will experience improvement. With the anticipation of anti-friction bearing demage will reduce the repair of any units of heavy equipment caused by damage to the anti-friction bearing. The purpose of creation of this tool is to help examine and analyze the damage often occurs on anti-friction bearing in unit of heavy equipment. Method of making a tool anti-friction bearing damage analysisis, on unit of heavy equipment with operating conditions approachh happens i.e. aspect of the workload and working temperature. Simulationas media tool anti-friction bearing damage can be done. The result of manufacture of tool breakage analysis of anti-friction bearing this could make it easier to know the working conditions and the variable load and speed rounds so the data parameter causes damage taken (annihilation due to the influence of vibration and haeat which occurs). Components anti-friction bearing damage analysis tool i.e. dinamo 3 phase 1500rpm, inventer, coupling flens Æ6’, shaft Æ70mmx600mm, pillow bearing Æ70mm, Housing bearing and punch, inner pack capacity 10ton, ball bearing, frame.

Abstract

The research in corrosion rate and mechanical properties for submerged arc welding of Steel construction through heat treatment, was done to study the effectiveness of the use of Post-Weld Heat Treatment (PWHT) using flame oxy aceteline. Its used for reducing the residual stress which may cause reduction in corrosion of resistance. Based on the study, it can be concluded that the release of residual stresses in submerged arc welding by PWHT can reduce current densities up to 43.88 μA/cm2 at the specimen T300, and also reduce the rate of corrosion that sea water by concentration of 3.3% NaCl. The slowest of corrosion rate occurs in spesimen T300, i.e. 0.311 mm/year compared to the TT specimen that has corrosion rate of 0.377 mm/year. In general, the microstructure of a welding is ferrite of grain boundaries that form structure of the pillar (columnar) with acicular ferrite be inside the columnar grains. The specimens T300 reached optimum hardness value 222.240 VHN but get the lowest value of tensile strength i.e only 54.5 kg/mm2.
