Design a single-reduction, spur gear-type speed reducer with all components. Specify the two

gears, two shafts, four bearings, and a housing (with fasteners). This gearbox must fit into the

condition shown below:

A water turbine transmits 50 kW of power to a pair of gears at 4500 rpm. The output of the

gear pair must drive an electric power generator at 3600 rpm. The center distance for the

gear pair requires not to exceed 150 mm.

Project Requirements:

1. Design the gearbox. Show all calculations, selection processes, and detailed analysis.

2. Make detailed component drawings for two shafts and the housing.

3. Demonstrate an assembly drawing for the gearbox.

Submission:

1. A completed project report with your design, analysis, and drawing. Save your report as a

PDF file.

2. A zip file includes all your CAD drawings.
