Course Objectives
(1) Mechanical design is the forefront study in manufacturing (mechanical products). Perform theoretical analysis of basic studies, match theory to objects and phenomena, and learn how to design machinery. Acquire a design method for mechanical elements, as it is an essential technology for the production of machinery.
(2) Learn how to design and select components such as gears, bearings, seals, and belts, which are typical rotating machine elements, and confirm previously learned content through exercises.
(3) Explain and give full recognition to the importance of the mechanical elements that make up the machine, including design examples for various machine examples, and to bring out a willingness to learn more voluntarily through application problems and exercises that are directly connected to the machine.

Assigned Department Objectives
Teaching Method
Outline:
Since machine design is an essential technology for producing machines made up of many mechanical elements, it is essential to obtain a method for designing machine elements. This course will offer how to design and select rotary machine components such as gears, bearings, and seals, which are typical mechanical components of rotating machinery such as gear reducers. As theories to objects and phenomena, and learn are mapped, learn the importance of the mechanical components that make up the machine by referring to the design examples of various machines. In this way, recognize the importance and necessity to reflect basic studies such as strength and lubrication in the design of mechanical elements.
This course will be held in a lecture style, and taught by an instructor who is in charge of machine design in a company using his experience. It will deal with selecting mechanical elements such as gears, axles, sliding bearings, and sealing devices.
Style:
Classes will be held in a lecture style. There will be assignments as appropriate.
Notice:
(1) Always pay attention to how to respond to problems encountered in the real situations.
(2) Understand the basic technologies such as of strength design and lubrication design for more application.
Students who miss 1/4 or more of classes will not be eligible for a passing grade.
