Couplings: Selection, Installation, and Failure Modes
| 26 – 30 Jan. 2026, Abu Dhabi | 19 – 23 Oct. 2026, Abu Dhabi |
COURSE OVERVIEW:
Couplings are vital mechanical components designed to transmit torque between two shafts while accommodating various degrees of misalignment and protecting sensitive machinery from shock loads. This course provides a comprehensive technical exploration of coupling technology, moving from basic rigid designs to sophisticated high-speed flexible membranes and fluid couplings. Participants will learn the fundamental physics of power transmission and how specific coupling choices directly influence the vibration profile and bearing life of rotating equipment.
The scope of this training includes a deep dive into the selection process, where factors such as torque density, axial end float, and environmental conditions are analyzed to match the right coupling to the application. We will examine the differences between metallic and elastomeric elements, as well as the specialized requirements for API-rated couplings used in critical oil and gas services. Detailed coverage is provided on the mechanical limitations of each design, ensuring that technical personnel can make informed decisions during the engineering and procurement phases.
Furthermore, the course places heavy emphasis on precision installation and the forensic analysis of failure modes. Attendees will explore the specific signatures of coupling distress, such as fretting, fatigue cracking, and lubrication breakdown. By understanding the root causes of coupling failure—ranging from improper alignment to torsional resonance—maintenance teams can implement robust installation procedures and predictive monitoring techniques that significantly reduce unplanned downtime and extend the mean time between failures for the entire drive train.
COURSE OBJECTIVES:
After completion of this course, the participants will be able to:
- Categorize the various types of couplings based on their mechanical design and flexibility.
- Select the optimal coupling type for specific industrial pump and compressor applications.
- Calculate the required torque ratings and service factors for different drive systems.
- Evaluate the advantages and disadvantages of lubricated versus non-lubricated couplings.
- Perform precision installation of couplings using laser and dial indicator methods.
- Interpret the impact of misalignment on coupling longevity and machinery vibration.
- Identify the root causes of elastomeric element degradation and failure.
- Diagnose metallic fatigue and fretting corrosion in gear and disc couplings.
- Apply the correct torque values for coupling bolts and interference fits.
- Manage the specific lubrication requirements for high-speed gear couplings.
- Implement safety standards and guarding requirements for rotating couplings.
- Analyze failure signatures to distinguish between overload and fatigue incidents.
- Develop a comprehensive inspection and maintenance checklist for coupling assets.
TARGET AUDIENCE:
Mechanical Maintenance Engineers, Reliability Technicians, Rotating Equipment Specialists, Plant Supervisors, and Millwrights involved in the upkeep of power transmission systems.
TRAINING COURSE METHODOLOGY:
A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.
The course participants shall be evaluated before, during, and at the end of the course.
COURSE CERTIFICATE:
National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
