Robert Tata passed away on March 8, 2014 in Huron Ohio. His surviving daughter and heir, Judy Tata, has decided to continue to offer his courses to the engineering community as a lasting tribute to her father. Judy has named her husband Eric Myers as the technical contact for the courses.

Eric has a BSME in Mechanical Engineering from Northern Arizona University in Flagstaff Arizona. He currently works for Raytheon Company in Tucson Arizona and has 13 years of experience. He specializes in Mechanical, Systems Engineering and Electronics Packaging. For 6 years at Raytheon, Eric worked with customers and peers to provide meaningful Senior Design projects at both local and national colleges.

The author has a BSME from Case-Western Reserve University, Cleveland, Ohio. He is a registered Professional Engineer in the State of Ohio. He has had 40 years of Mechanical Engineering experience, 26 of which were with the General Motors Corporation. While there, he obtained United States Patent Number 4,645,432, "Magnetic Driven Vehicle Coolant Pump". He went on to become a leader in anti-friction bearing applications in both the vehicle and industrial fields. Prior to that he was employed by TRW, Cleveland, Ohio where he was responsible for bearings, gears, and mechanical power transmission in the aircraft and missile fields under the tutelage of Mr. Tom Barish, a leading mechanical power transmission consultant.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

This course provides, with ample illustration, technological information on all phases of ball bearings. It starts out with the basics such as description, theory of operation, sizes, and types. The features and capabilities of the three different kinds of ball bearings are described along with an explanation of the compromise that is involved in the design of inner and outer ring pathway curvature and shoulder height. Next, a discussion follows of how ball bearing operating life is calculated and why it is given as a probability number and how preloading spindle bearings can improve the accuracy of manufacturing machines. Finally, bearing seals, material, and lubrication methods are given along with an explanation of how the use of double sealed ball bearings can be an advantage to the machine designer. Every effort has been made to provide step-by-step, easy to read material with factual information and descriptive illustrations to enhance the student's knowledge of ball bearing technology.

Since ball bearings are used in a wide variety of product, this course will provide useful information to a wide variety of engineering disciplines including Mechanical, Electrical, Automotive, Civil, Manufacturing, and any other with a Machine Design option or having an interest in mechanical products. There is always a need for new faces and new ideas in the bearing industry to improve product performance in such demanding fields such as high speed aircraft and space vehicles where light weight and extremely harsh environments continually push the performance of today's products to their limit. Even more earthly environments such as wind turbines are proving to be a design challenge to the bearing engineer because of unexpected and sometimes hard to explain failures that are occurring in ever increasingly sized megawatt units.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Much scientific study and development work has been completed on gears. Formulas have been developed and standards established to make gear design and application as easy an endeavour as possible. The gear tooth has been so successfully perfected that, when two gears mesh, almost perfect rolling takes place. Most gears operate in the high 90% range similar to anti-friction bearings where virtual pure rolling does take place.

This course provides, with ample illustration, established technological information on gears. It has almost as many pages of illustrations as it does text. It starts out with terminology and types of gears. Next the type of material used and the method of manufacture are explained. A sample problem is posed whereby allowable transmitted horsepower formulae for tooth bending and pitting are used to evaluate a simple gearset. The gearset is then revaluated with several design options and the results compared to baseline data. Gear mounting is examined by solving an equation for gear rim design and an equation for shaft size. Finally drawings are presented and expert analysis given for gears in power transmission devices.

This course is written in an effort to make it attractive to Mechanical Engineers or anyone else with a technical discipline that is interested in broadening their background in mechanical power transmission basics. The field is full of opportunities and challenges especially in the aerospace industry where new gear variations have been developed that perform beyond the limits of today's existing designs and the search is on for even better concepts that will deliver even more power with less weight for future generation vehicle use.

099-Roller Bearing Technology

(3.8) 12 Reviews

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

Roller bearings, along with ball bearings, are designed and manufactured to such perfection they operate in the high 90% efficiency range and are known as "anti-friction" devices. This course provides engineering information on the two different types of roller bearings; cylindrical roller bearings and tapered roller bearings. Engineering information is provided with easy to follow text and an ample amount of descriptive illustrations. Detailed explanations of both types of bearings are given along with material and manufacturing methods. The advantages of using the many different configurations of cylindrical roller bearings and the unique design and operating characteristics of tapered roller bearings are revealed. There are pertinent sample problems of each that teach how to calculate predicted design life under a number of different operation conditions. Recommend lubricants are given for different operating conditions along with a unique graph on how to calculate lubricant viscosity for various size bearings operating at a variety of speeds and temperatures. Finally, sketches are given of both types in actual applications with expert analysis of each.

Since roller bearings are used in a wide variety of product, this course will provide useful information to a wide variety of engineering disciplines including Mechanical, Electrical, Automotive, Civil, and Manufacturing and any other with a Machine Design option or having an interest in mechanical products. There is always a need in the bearing industry for new faces and new ideas to meet the challenge of designing higher performing products for use in the aircraft, space vehicle, and wind turbine industries.

105-Automotive Bearing Technology

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description:

This course deals with the application of anti-friction bearings in automotive vehicles. It contains pertinent text along with and an ample number of illustrative sketches to provide the student with an easy grasp of the subject matter. It explains the use of bearings in manual and automatic transmissions. It has an in depth discussion of vehicle wheel bearings. Wheel bearings are considered safety items by the auto manufacturers and their design and manufacture is of vital importance to passenger well being. There is a discussion regarding the new "Integral Spindle Wheel Bearing" which was designed and mass-produced by one of the major U.S. car companies. Integral spindle wheel bearings are incorporated in the new front-drive light weight passenger cars and are considered a major engineering and manufacturing break through. Finally, there is information presented on the special design aspects of engine coolant pump bearings and an explanation of the operation of the drive axle differential system. The bulk of the mathematical equations for this course are contained at the end in the form of Appendix pages for reader convenience.
