Assigned Department Objectives
Teaching Method
Outline:
General or Specialized : Specialized
Field of learning : Materials, Design and Production
Required, Elective, etc. : Elective must complete subjects
Foundational academic disciplines : Engineering,/Mechanical Engineering,/Design Engineering, Machine Functional Elements, Tribology
Relationship with Educational Objectives :
This class is equivalent to "(3) Acquire deep foundation knowledge of the major subject area ".
Relationship with JABEE programs :
The main goal of learning / education in this class are "(A), A-2", also "C-1" is involved.
Course outline :
The design task is a two-stage helical gear reducer, and each person is given specifications for transmission power and reduction ratio, and each person completes a design calculation and a manufacturing drawing (assembly drawing and parts drawing) based on the design calculation. In this process, while understanding the design procedure, design calculation method, and various standards, the knowledge of machine design method and machine construction method learned so far and the knowledge of drafting are acquired a method for machine realization.
Style:
Course method :
Each person will proceed with the design according to the text and lectures on the blackboard. Necessary materials other than the text will be prepared. After the design document is completed, the student will start creating drawings using CAD (hardware and software).
The design calculation sheet and drawing will be submitted and returned with comments as appropriate. Then, each person should complete the design calculation sheet and drawing while making trajectory corrections as necessary.
Grade evaluation method :
Evaluation of the learning process in the design of a gearbox through exercises (10%). Design calculations are submitted in the form of a report, and drawings are submitted in the form of a CAD data file and printed drawings. Evaluate the submitted design calculation (40%) and drawings (50%). Only those who have submitted all of the exercises, design calculation sheets and drawings will be evaluated. Failure to submit any of the above items will result in a failing grade.
Notice:
Precautions on the enrollment :
This is a "class that requires study outside of class hours". Classes are offered for 15 hours per credit, but 30 credit hours are required in addition to this. Follow the instructions of your instructor for these studies.
Course advice :
Knowledge about mechanical elements such as gears, shafts, bearings, and keys, knowledge for operating design solutions, knowledge for controlling the design process, etc. are required. Make sure you understand the contents of related basic subjects so that you can use.
Foundational subjects : All subjects related to materials, manufacturing technology and machine design and drawing
Related subjects : Advanced Design Engneering (Advanced Engineering Course 1st year), Precision Machining (Advanced Engineering Course 1st)
Attendance advice :
Do not miss classes.
Complete the design of each unit within the specified period.
You must be late for up to 25 minutes, and if you exceed this, you will be considered absent.
