MODULE DETAILS

Module 3: Mechanical Drive Systems

 

Nominal duration: 5 weeks (60 hours total time commitment)

 

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

 

MODULE PURPOSE

 

 

Most engineering professionals working with drives will confirm that there are major benefits in installing and maintaining mechanical drives correctly the first time. Typical areas that can be dramatically improved include: wear and tear on equipment, unscheduled downtime and production losses, energy consumption operating efficiencies.

 

This module has been designed to examine the majority of mechanical drives such as belts, chains and gears in terms of improved lubrication, proper alignment, and fastening techniques. You will have an opportunity to discuss drive design applications, operations, maintenance and management issues and you will be provided with the most up-to-date information and best practice in dealing with the subject. You will develop the skills and ability to recognize and solve drive problems in a structured and confident manner.
