# Two-Disc Cycloidal Gearbox Design

## 1.  Engineering Drawings

### Description
The design is a compact, scalable cycloidal gearbox featuring two cycloidal discs, intended for high-torque, low-speed applications. The modular nature allows for modifications in both size and material type. The current version has a diameter of 90 mm and a height of 54 mm.

2D & 3D Engineering Drawings Include:

- Exploded view

- Cross-sectional view

- Top, side, and front views

- Dimensional tolerances

- Shaft alignment and key interfaces

- Mounting hole patterns
