Programme overview
Introduction:
Industrial gearboxes and power transmission, with gear inspection and failure analysis, is a 5-day course for maintenance, reliability and rotating equipment teams that ends with a Gearbox Failure Investigation and Maintenance Plan for a case drive train. Organisations lose production when gear units are undersized, run on the wrong oil or are rebuilt without finding why teeth pitted, scuffed or broke, and when couplings, belts and chains wear unnoticed. Nominees already maintain gear units and drives at work and learn through case studies built on failed gears and site data. CoreConcept Training Center delivers this industrial gearboxes course.
Course Objectives:
- Identify gear types, tooth geometry and gear unit designs, and calculate ratio, torque and efficiency for drive trains in service
- Evaluate gear unit ratings with ISO 6336 and AGMA 2001 concepts and select service factors and thermal capacity for replacement units
- Inspect gear units for backlash, tooth contact pattern and mounting condition, and specify the gear lubrication method and oil grade
- Classify gear tooth damage with ISO 10825 terminology and trace pitting, scuffing and fatigue fracture to their root causes
- Maintain flexible couplings, belt drives and chain drives to correct tension, wear limits and replacement triggers
- Decide between repair, overhaul and replacement of gear units and build a drive train maintenance plan from condition evidence
Target Audience:
- Mechanical maintenance teams responsible for installing, inspecting and overhauling gear units on conveyors, mixers, crushers, cooling tower fans and pumps
- Reliability engineering staff responsible for eliminating repeat gearbox and drive failures on critical production lines
- Rotating equipment technicians responsible for replacing and tensioning couplings, belt drives and chain drives
- Maintenance planning staff responsible for preventive task lists, spare gear units and overhaul scopes
- Workshop teams responsible for gear unit strip-down, measurement and rebuild acceptance

- Gear Unit Rating Review
- Service Factor Selection
- Backlash and Contact Pattern Measurement
- Gear Lubricant Specification
- Gear Tooth Damage Classification
- Belt and Chain Drive Tensioning
- Overhaul Decision Making
Why Attend This Course:
- Produce a Gearbox Failure Investigation and Maintenance Plan for a case drive train, ready for the maintenance manager and the reliability lead
- Decide whether a damaged gear unit should be repaired, overhauled or replaced, using tooth damage evidence, ratings and condition data
- Avoid undersized replacement units, the wrong gear oil and over-tensioned belts that cause repeat drive train breakdowns and lost production
- Share backlash and contact pattern record sheets, tensioning procedures and tooth damage charts with workshop and planning colleagues
Conclusion:
Back at work, the participant gives the maintenance manager and the reliability lead a Gearbox Failure Investigation and Maintenance Plan that records the root cause of a gear unit failure, the repair, overhaul or replacement decision, the rating and service factor check for any new unit, and the preventive tasks for gears, couplings, belts and chains on the drive train. Planners use it to set inspection intervals and spares, and the workshop uses it to set rebuild acceptance. After the first overhaul under the plan, the unit should review backlash records, contact patterns and repeat failures.
Frequently Asked Questions (FAQ):
What should participants know before an industrial gearboxes and power transmission course?
Participants should already maintain, inspect or plan work on gear units, couplings, belts or chains. No gear design background is needed. Bringing gear unit nameplate data, overhaul reports or photographs of damaged gears helps participants apply the case work to their own drive trains.
How does an industrial gearboxes and power transmission course differ from a vibration analysis or shaft alignment course?
It concentrates on the gear unit and drive components themselves: gear types, ratings, service factors, backlash, contact patterns, lubrication, tooth damage, couplings, belts and chains. Vibration analysis and alignment courses teach those measurement techniques in depth; here they appear only as an overview.
Why do industrial gearboxes fail early after a replacement or overhaul?
Most early failures trace back to an undersized unit chosen without a service factor, the wrong gear oil, poor mounting or an unchecked contact pattern. Pitting, scuffing and root fatigue then follow, so selection and installation checks matter as much as the gears.
What do participants take back from the industrial gearboxes and power transmission course?
Participants take back a Gearbox Failure Investigation and Maintenance Plan for a case drive train, with a failure investigation worksheet, a repair or replace decision matrix, backlash and contact pattern record sheets and a preventive task list for gears, couplings, belts and chains.
