Gearboxes are an integral part of today’s industrial machinery. A gearbox is utilized to increase the output torque or change the speed (RPM) of a motor or a turbine. They allow the driver and driven equipment to operate at their most efficient and optimum speeds and torques. Proper selection, troubleshooting and maintenance of gearboxes is essential in order to make sure they can do their job.

This course covers the specification, installation and operation of gears and gearboxes in modern plant. It reviews current design standards and discusses how to specify and how to use a gearbox. Gearbox installation, lubrication, health monitoring and failure interpretation are discussed in detail. Practice exercises, videos, case studies for an engaging and memorable learning experience

Upon successful completion of this course, the delegates will be able to:

• Apply safe working practices and understand the principles of preventive and first-line maintenance
• Correctly diagnose a range of mechanical faults and plan a suitable course of action
• Understand the principles of power transmission systems; recognize, remove and refit taper-lock bushes, keyed shafts, belts, chains & couplings; install & align shafts; tension drive train components
• Correctly remove and refit various types of bearings (roller, ball etc.) identify various bearing types, understand their typical applications & recognize common defects
• Practice methods of removing broken studs
• Recognize stripped threads and correctly use thread repair equipment
• Manufacture gaskets and understand how to remove and replace seals and gland packing
• Understand the operation of various gearboxes, (helical, spur and worm-wheel)
• Correctly dismantle and replace drive belts
