Machine Design Workshop using Gear Reducers, to be held online on July 2

The IR Engineer Education Research Institute is hosting a public seminar where participants can learn the entire mechanical design process—from basic gear specification design to strength calculation, selection of shafts, bearings, and keys, and summarizing design results for documentation—through gear reducer design exercises.

In machine design, "design calculation" to derive solutions under requirements and constraints, and "design documentation" to accurately convey results to third parties are essential. However, knowledge learned in isolation (gears, shafts, bearings, keys) often fails to connect as a coherent workflow for real projects.

### Seminar Overview - Seminar Title: Practical Machine Design Skill Development Course using Gear Reducers - Format: Online via Zoom - Date/Time: July 2, 2026 (Thu) 10:00–17:00 - Fee: 49,500 JPY per person (tax included) - Lecturer: Keiichi Suzuki (Representative, Suzuki Professional Engineer Office)

### Details Using a "two-stage spur gear reducer" as a subject, this seminar focuses on hands-on practice, covering gear specifications (number of teeth, module, center distance), strength calculation, and selection of shafts, bearings, and keys. It also covers the evaluation of design results and key points for compiling them into design documents, allowing participants to master the entire flow from calculation to report generation.

### Seminar Program 1. Fundamentals of mechanical design and gear reducer overview 2. Basic gear specification design (reduction ratio to number of teeth/center distance) 3. Gear and shaft strength design (design judgment based on safety factors) 4. Shaft strength design (torsion, bending, complex) and shaft diameter calculation 5. Selection of bearings and keys (evaluation and selection procedure for standard parts) 6. Evaluation of design calculation results and creation of design documents

### Target Audience - Engineers involved in machine design and drafting - Those wishing to learn practical gear reducer design and strength calculation - Those wishing to deepen knowledge in component selection and design (gears, shafts, bearings, keys) - Those wishing to acquire skills in creating design documents based on design calculations
