Gate 01
Wearable constraints
Freeze mass, axial length, body clearance, cable route, and comfort limits before chasing torque margin.
Compact cycloidal reducer review for wearable robot hip, knee, ankle, rehabilitation, and industrial exoskeleton axes where mass, safety, smoothness, and peak assist torque must be balanced.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Wearable mass budget | Reducer, motor, housing, battery, harness, and fasteners reviewed at joint level | A reducer that is acceptable on a bench can be rejected when joint mass and comfort are checked on a human-worn device. |
| Peak assist torque | Gait phase, lift support, stumble recovery, and safety stop reviewed separately | Assistive devices need enough peak torque without creating excessive reflected inertia, noise, or heat. |
| Smoothness and documentation | Backlash method, no-load torque, noise, run-in, inspection record, and validation report plan | Wearable and rehab projects need evidence that supports user-facing trials and buyer-side device validation. |
Wearable Joint Review
Exoskeleton and rehabilitation projects add user-facing constraints to reducer sourcing. The reducer must fit the joint and support validation without creating mass, noise, heat, or safety-stop problems.
| Axis / Module | Sizing Driver | Integration Review | Buyer Evidence |
|---|---|---|---|
| Hip assist joint | Peak assist torque, axial length, mass budget, harness clearance, and user comfort. | Compare compact and flat reducer layouts against motor, housing, cable route, and body-side clearance. | Assist torque profile, mass budget, envelope drawing, noise target, and temperature limit. |
| Knee / ankle assist joint | Gait phase torque, safety stop, reflected inertia, low-speed smoothness, and output support. | Review backlash, stiffness, no-load torque, bearing support, and fastener access before sample selection. | Gait profile, safety-stop case, backlash method, smoothness note, and sample test plan. |
| Rehab or clinical prototype | Noise, repeatability, cleanliness, documentation, inspection records, and validation traceability. | Plan component evidence and buyer-side validation records before user-facing trials. | Required record format, material and heat-treatment route, run-in notes, and acceptance criteria. |
Gate 01
Freeze mass, axial length, body clearance, cable route, and comfort limits before chasing torque margin.
Gate 02
Separate assist torque, safety stop, no-load torque, backlash, noise, and temperature rise in the first review.
Gate 03
Agree inspection records, run-in expectations, sample acceptance method, and buyer-side validation needs before shipment.
| Decision Point | Choose When | Verify Before Quote | Next Internal Step |
|---|---|---|---|
| Wearable mass budget is the first sourcing filter | Best for wearable robotics, rehabilitation, and industrial exoskeleton engineers balancing compact torque density with user comfort and validation evidence. Use this path when wearable mass budget (Reducer, motor, housing, battery, harness, and fasteners reviewed at joint level) is more important than starting from a generic gearbox size. | A reducer that is acceptable on a bench can be rejected when joint mass and comfort are checked on a human-worn device. Include wearable joint axis, user load range, gait phase, assist torque, peak torque, and safety stop assumptions in the first RFQ packet. | Compare Application Solutions |
| Mechanical interface risk is visible early | Map assist torque by gait phase, peak event, safety stop, and expected user interaction instead of only motor nameplate torque. | Over-sizing creates user comfort failure: Review reducer mass, axial length, output support, and harness constraints before torque margin is finalized. | Send RFQ Package |
| Sample acceptance must be measurable | Use prototype planning when peak assist torque must be confirmed against buyer-side machine tests. | Safety stop not included in sizing: List stop, stumble, impact, and overload assumptions separately from normal assist torque. | Plan Prototype Validation |
| Phase | Engineering / QC Checkpoint | Buyer Output |
|---|---|---|
| Requirement baseline | Wearable joint axis, user load range, gait phase, assist torque, peak torque, and safety stop assumptions; Mass budget, axial length limit, mounting drawing, cable route, and skin-side clearance constraints. Confirm drawing revision, quantity, destination, and timeline in the same packet. | A quote-ready RFQ sheet that separates required performance from preferred options. |
| Engineering fit review | Map assist torque by gait phase, peak event, safety stop, and expected user interaction instead of only motor nameplate torque. Review reducer mass, axial length, noise, smoothness, no-load torque, and thermal behavior against wearable comfort limits. Record open issues before sample cost and lead time are frozen. | A reducer shortlist and issue log for Exoskeleton Compact Cycloidal Reducer. |
| Prototype or incoming validation | Measure wearable mass budget and peak assist torque against the agreed method. Review reducer mass, axial length, output support, and harness constraints before torque margin is finalized. | Inspection and test evidence with pass/fail limits, measured values, and revision actions. |
| Batch control and export readiness | Safety stop not included in sizing: tie the control plan to outgoing inspection, packaging, labeling, and shipment records. | Repeat-order package covering drawing baseline, CTQ records, packaging rules, forecast, and Incoterm. |

CAD / STEP Data Pack
Use this application package request when your team needs a model file, envelope drawing, or engineering data before committing layout space. We verify the target family, revision, and release constraints first so buyers do not design around the wrong CAD file.
Confirm released model files, closest reference family, and file-release constraints before CAD freeze.
Align motor pilot, output flange, hollow bore, cable route, bolt circle, and axial envelope early.
Request backlash method, run-in note, inspection fields, and sample acceptance data for the selected family.

Best for quick model availability and file-release checks.
Submit the minimum engineering context needed for model-file screening and revision-safe follow-up.
Application RFQ
Include the machine module, duty profile, ratio, torque, backlash, interface limits, and validation plan so engineering can respond against the real application risk.
The offer is reducer sourcing and customization support. Buyer-side device certification remains with the OEM, while component evidence and inspection records can be planned during RFQ.
Mass, comfort, noise, smoothness, user-facing safety stops, and validation records become more important because the mechanism is worn or used near people.
Send the joint axis, assist torque profile, mass budget, envelope drawing, backlash and noise targets, safety stop assumptions, prototype quantity, and validation plan.
Program Route
Exoskeleton Compact Cycloidal Reducer defines the use-case risk. The next step is to connect it to the reducer family, drawing request, DFM review, and validation records.
Check reducer architecture, model family, envelope class, and CAD availability before the quote is treated as final.
Review the machine or robot axis context so torque, shock, backlash, stiffness, and validation risk stay tied to real use.
Move from fit review into DFM, sample validation, inspection records, packaging, and repeat-order control.
Use these links when the buyer is ready to send requirements, compare directories, or review sourcing guidance.
