Condition Monitoring

Condition Monitoring

In this course we will examine each of these questions and the interrelation of each with a primary focus on how this information can be used to define the actions required to keep the gearbox running properly and to allow maintenance planning.

WHAT: There are many parameters that provide information about the condition of an operating gearbox, some are lubrication centric while others are operationally centric. Major lubrication centric parameters include lubricant temperature, pressure (if the lube is a liquid pumped system) and flow rate. Major operational centric parameters include noise, vibration, chip detection and characterization.

Why: Each parameter, individually and in combination, can provide insight into the condition of the gearbox and its individual components. We will present not only the parameter descriptions, but the information provided by each and the actions that may be suggested by these observations.

How: Major emphasis of our discussions will focus on this most important factor. There are a variety of ways we can collect the data required to estimate remaining operational time and risk of premature failure. Even more importantly, however, our discussion of the “how” will address the relation of the function of the gearbox and the risks associated with parameters evaluated. Some parameters are best evaluated online as the gearbox is operating while others are best evaluated offline using “samples” obtained from the operating gearbox. Our discussion will address the differences and the situations in which each is appropriate.

_{This course is online. A webcam on your computer equipped with a microphone and speakers/headset are required for participation. Space is limited to 20-25 participants per course. Course materials will be mailed in hard copy. Please make sure to indicate your preferred mailing address in the registration process.}

Learning Objectives

• Recognize the specific parameters that need to be monitored.
• Understand the hardware and data interpretation required for each monitored parameter.
• Discuss relative importance of each parameter and significance of data obtained with respect to the operational capability of the gear system.
• Discuss potential actions required based on data obtained by each monitoring method.
• Understand the best techniques for obtaining data from an operating gear system that can be used to predict the operational performance of the system.
• Understand that data collected does not necessarily provide a “yes” or “no” decision point but rather can support rational judgements relative to maintenance scheduling.
• Review how data collected is used to determine specific lubricant replacement scheduling.

Instructors

Raymond J. Drago, P.E.

Raymond J. Drago is Chief Engineer of Drive Systems Technology, Inc. (DST), a mechanical power transmission consulting organization that he founded in 1976. Mr. Drago also worked for the Boeing Company – Helicopters Division until his retirement after 37 years of service. Currently Mr. Drago is involved in the analysis, design, manufacture, assembly, and testing of many gear systems. In his role with DST, Mr. Drago is active in all areas of mechanical power transmission, including the design and analysis of drive systems in a very diverse field of application from heart pumps to very large mining & mill gears. He has used his 58 years of gear technology experience to prepare and deliver more than 150 Technical Papers and 385 courses dealing with various aspects of gear design and analysis.

I started working at Boeing in 1967 and continued until my retirement in 2004. I started Drive Systems Technology in 1976 as a part time activity while still working at Boeing (with Boeing’s knowledge and approval, under strict guidelines) which eventually grew to the point where I retired early from Boeing in order to pursue DST as a full-time activity.
