Hotel & Travel Information
This course will provide attendees with state-of-the-art information about wet clutches and brakes for the design of industrial machinery and vehicular clutches and brakes. These clutches and brakes offer longer life and better energy management without the use of asbestos. The basics of shear of oil between stators and rotors will be used as the foundation for understanding sound design principles. This will be followed by lectures on lubricants, facing materials, and reaction surfaces. The nature of heat transfer and forced cooling will be explained. Finally, an overview of design principles for brakes and clutches will be presented, with example calculations for the more important issues encountered by engineers.
Learning Objectives
By attending this seminar, you will be able to:
- Describe the fundamental design principles that govern best practices in wet clutches and brakes
- Discuss the basics of shear of oil between the stator and rotor
- Contrast the differences between classical lubrication theory and the theory of confined films
Who Should Attend
This course is intended for engineers, designers and engineering managers who desire a thorough understanding of wet disc clutches and brakes.
Prerequisites
An undergraduate degree in any engineering discipline is recommended, but not essential. The use of calculus in some advanced calculations is demonstrated, but understanding of these calculations is not essential to the basic ideas presented.
