10P Planetary Gearbox Mechanical Interface v1.0¶
Status: Public engineering evaluation reference
Release date: 2026-10-06
Controlled drawing code: SG01PD10
This page summarizes the mechanical-interface information that is suitable for public early evaluation from the current SigGear controlled 2D drawing.
Warning
This page is not a manufacturing drawing. Use the current controlled drawing for final tolerances, detailed shaft geometry and production design release.
Controlled Envelope¶
| Item | Controlled / published reference |
|---|---|
| Nominal gearbox diameter | 10 mm |
| Output-side extension shown on drawing | 7.5 mm (+0.1 / -0.3) |
| Gearbox body length | L, stage-dependent |
| Output-side interface | 2 × M1.6 threaded holes, depth 2 mm, on the published Ø7.0 ±0.05 reference circle |
| Input-side interface | Input-side center/interface geometry is controlled; request the drawing for final motor matching. |
Stage-Dependent Length¶
The controlled drawing uses L for the gearbox body length. L changes with the selected stage count.
Use the 10P product page for the currently published 1-stage to 4-stage length and ratio table.
Public Simplified CAD¶

The released public STEP is a single-solid simplified external-interface model for early packaging and mechanical Design-In. It represents the 4-stage reference configuration only and intentionally omits the internal planetary transmission construction.
A detailed full-assembly 10P STEP is still retained as configuration-controlled engineering CAD and is not published as a raw download.
For another stage count or final production release, request the configuration-matched controlled CAD / drawing.

Design-In Boundary¶
Before final design freeze, confirm:
- Stage count and reduction ratio
- Exact gearbox body length L
- Output shaft / mounting interface
- Motor-side pilot and shaft interface
- Motor speed and torque operating point
- Radial / axial load condition where relevant
- Configuration-specific CAD revision
