Instructor by : Andi Sularto
DESCRIPTION
To equip participants with the knowledge to identify and recognize characteristics that render bearings unserviceable and/or unacceptable upon engine operation. Participant will learn the basics of failure analysis identification and the probablecauses of failures. Participant will also be informed of the cleanliness requirements for the oil lubrication system and will be taught proper handling and installation techniques, methods, and practices to minimize the opportunity for premature bearing failures.
PURPOSE
- Participants will understand the importance of bearing lubrication and installation in achieving calculated bearing life
- Participants will become confident in performing level I inspection and bearing serviceability
- Participants will be equipped with tools to assist them in resolving complex problems and in thinking laterally to fullyexplore possible causes of a problem
MATERIAL OUTLINE
1.
Level Inspection for serviceability :
- Demagnetization and cleaning
- Visual inspection
- Dimensional inspection
- Minor repair–blending/stoningof high material
- Marking
- Lubrication, preservation and packaging
- Disassembly and cleaning forinspection
- Types of bearing damage and failuremodes may include:
- Wear
- Indentation
- Smearing
- Surface distress
- Corrosion
- Electrical current
- Flaking
- Cracks
- Cage damage
- Classroom participation in analysis
2. Lubrication system cleanliness :
- Purpose of lubrication in bearings
- Bearing preservation
- Types of oils recommended for aero engine, gearbox, and other application aero engines
- Lubrication checks – methods and frequencies
- Flushing of oil system to remove debris
3. Bearing installation :
- The importance of cleanliness
- Mounting and installation of bearings including methods
- Inspecting and correcting fits and clearances
4. Workshop / Case Studies
WHO SHOULD ATTEND :
Bearing room inspectors, bearing removal and installation personnel, and engineering staff responsible for engine reliability of commercial aircraft or other aero engine and gearbox equipment. Rotating equipment Engineers, reliability engineers, mechanics, and maintenance supervisors. Anyone interested in rotating equipment performance.
