Gear Box Overhauling & Maintenance

Gear Box Overhauling & Maintenance
Summary

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.

In this 5-days B. Khebra’s Gear Box Overhauling & Maintenance course participants will learn 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, overhaul, maintenance and failure interpretation are discussed in detail. Practice exercises, videos, case studies for an engaging and memorable learning experience

  • BK Management Team believe that learning is not only about acquiring technical skills, it is also about learning behaviors & Competencies that are desirable for work in plant operation & maintenance critical dimensions. Our holistic teaching develops our delegates' personal effectiveness to function both as an individual and as a team player. The course delivery & modes of instruction will incorporate theory , practical skills and Q&A sessions. 
  • To enhance learning outcomes, theory sessions will comprise classroom based lecture that will intersperse with interactive discussions, scenario-based, case-study, group exercises, video clips, power point slides, learners' Guide and the application of various tools which will be provided to help in the delegates and participants of the learning’s objectives. With successful implementation of the learnt skills they are bound to enhance Individual & Organizational growth.
  • For online / Interactive Virtual sessions, Delegate should have a stable & good Internet connection on his Laptop.

On successful completion of this training course, BK’s Certificate with eligible Continuing Professional Education credits (CPE), will be awarded to the delegates , one CPE credit is granted per 50 minutes of attendance.
