2 Triệu về 1: Hộp số Nested Strain Wave Gearbox

It is designed to be fully 3D printed with minimal hardware required, making it a highly accessible build that visually breaks down complex mechanical engineering. It includes a custom base to display the final assembly while it runs.

(PLEASE NOTE: This build uses 2 2.5*6mm machine screws, along with the USB TT motor from MakerSupply.)

The Math (Gear Ratios)

The extreme reduction is achieved through four nested stages:

•    Stage 1: 20:1

•    Stage 2: 34:1

•    Stage 3: 48:1

•    Stage 4: 62:1

Bill of Materials (BOM)

•    All printed components (including display stand)

•    1x USB TT Motor (Amazon or MakerSupply)

•    2x 2.5x6mm machine screws (Note: These are the exact same screws used in the Cyber Brick build)

•    Lubricant (for the flexsplines)

Assembly Instructions

1. Mount the Motor: Install the USB TT motor into the assembly and secure it with the motor housing using the two 2.5x6mm machine screws.

2. Install Wave Guides: Snap the wave guides (top gear portions) securely into their designated places.

3. Prep the Flexsplines: Apply lubricant to the smooth side of the flexsplines (the flexible rings).

4. Seat the Flexsplines: Carefully install the lubricated flexsplines into their appropriately sized channels.

5. Final Drive: Press the wave generator onto the TT Motor shaft.
