Development Engineer at SKF AB
Spherical Roller Bearings
- Silent bearings for special applications:
To improve in Noise and Vibration level in SRBs, several physical specifications of the bearings were tested to identify the impact of each individual feature on noise and vibration. These target features were surface texture and surface roughness of each component, internal clearance, mechanical specifications of the lubricant, lubrication quality, lubricant filling degree.
- Wind turbine SRB Development:
Investigation and technical solution for excessive guide ring and roller wear.
- Root cause analysis of worn and fractured components: Fatigue, high friction wear, fretting, Brinelling and electric arc are the common causes for bearing failure. Root cause of these phenomena in diﬀerent application are not the same. Identification of the root cause needs special analysis for each case to be able to define the suitable solution.
- FMEA & DFMEA:
Failure mode analysis and design failure mode analysis for modified bearings
Project Engineer at National Oilwell Varco Norway
- Product Design and Development:
Oﬀshore lifting & handling (Oﬀshore and AHC Cranes and Winches) under DNV, ABS, and NORSOK regulations. The work included CAD design, structural analysis, Production control, FAT and SAT. -Component failure Root Cause Analysis: Planetary gears, gear wheel and pinions, hydraulic cylinders, hydraulic pumps and motors, bearings, structural July/2005 - August/2009
- FMEA & DFMEA:
For new products during and after design process.
- Research & Development:
After the bearings of an ultra size machine crashed drastically and unexpectedly, the Root Cause Analysis was to be held to understand what defect, why and how was initiated and developed in such a short time which caused the bearings to crash after passing less that 20% of the calculated life times by the vendors (SKF and FAG). Due to my material
engineering back ground, I got the chance to role in this regard. The initial visual inspections of the bearings indicated False Brinelling caused by Fretting and later by the lab investigation held by DNV (Det Norske Veritas) in Norway we found the indications of Fretting Fatigue as the main cause. Following this situation the company decided to find a reliable Condition Monitoring method among the existing methods in the market to prevent the catastrophic failure of the similar machines where I worked as the main planner and performer of the tests and developments of the project.
To evaluate the performance and the precision of the diﬀerent bearing damage detection methods and compare them to find the optimum method and set ups, I designed and constructed a lab test rig including 3 diﬀerent spherical roller-bearings. Two separate mechanisms were designed to apply variable axial and radial loads to the shaft. Two load-cells were used to measure the load rates separately.
