Gate 01
Transient event list
Document jump, landing, stumble, collision, stall, and emergency-stop events separately from average gait torque.
Cycloidal reducer qualification for quadruped hip, knee, leg, and compact actuator joints exposed to landing shock, stumble loads, high cycle duty, and outdoor service risk.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Landing shock case | Drop, jump, stumble, impact, and emergency-stop events reviewed outside steady gait torque | Legged robots damage reducers during transient events that can be invisible in average walking torque. |
| Duty-cycle heat | Walking, trotting, recovery, and mission duration checked with ambient temperature | Compact leg actuators can fail validation when heat and lubricant behavior are not evaluated with the mission profile. |
| Output support and sealing | Bearing span, moment load, cable route, ingress risk, and service interval reviewed together | Outdoor and field robots need reducer packaging decisions tied to contamination, shock, and repair access. |
Legged Robot Shock Review
Quadruped reducer selection must include jump, landing, stumble, collision, recovery, heat, sealing, and output support assumptions. A steady walking torque number is not enough for a quote-ready review.
| Axis / Module | Sizing Driver | Integration Review | Buyer Evidence |
|---|---|---|---|
| Hip abduction | Moment load, lateral shock, housing stiffness, cable route, and output bearing support. | Review bearing span and actuator shell stiffness before reducer OD and flange pattern are frozen. | Leg geometry, ground reaction assumption, moment-load case, and output support drawing. |
| Hip flexion / knee | Peak torque during acceleration, landing, stumble recovery, and emergency stop. | Compare compact cycloidal peak-load margin with motor thermal behavior and lubricant assumptions. | Gait profile, peak event list, duty-cycle heat expectation, and sample validation cycle. |
| Outdoor inspection leg module | Dust, moisture, low temperature, lubricant choice, corrosion exposure, and service interval. | Plan sealing and packaging around reducer, cable exit, fastener access, and field replacement route. | Environment statement, ingress target, maintenance interval, packaging note, and batch inspection fields. |
Gate 01
Document jump, landing, stumble, collision, stall, and emergency-stop events separately from average gait torque.
Gate 02
Check mission duration, ambient temperature, lubricant, ingress risk, corrosion exposure, and service access.
Gate 03
Tie leg geometry, moment load, output bearing support, backlash method, and field-service plan to the sample acceptance criteria.
| Decision Point | Choose When | Verify Before Quote | Next Internal Step |
|---|---|---|---|
| Landing shock case is the first sourcing filter | Best for quadruped and legged-robot OEM teams that need high shock-load margin without losing compact actuator packaging. Use this path when landing shock case (Drop, jump, stumble, impact, and emergency-stop events reviewed outside steady gait torque) is more important than starting from a generic gearbox size. | Legged robots damage reducers during transient events that can be invisible in average walking torque. Include robot mass, leg geometry, joint axis, gait profile, rated torque, peak torque, and landing shock assumptions in the first RFQ packet. | Compare Application Solutions |
| Mechanical interface risk is visible early | Separate walking, trotting, jumping, landing, stumble, collision, stall, and emergency-stop torque cases. | Peak impact hidden inside average torque: List jump, landing, stumble, collision, and emergency-stop cases as separate RFQ rows. | Send RFQ Package |
| Sample acceptance must be measurable | Use prototype planning when duty-cycle heat must be confirmed against buyer-side machine tests. | Field environment ignored: Define ingress, dust, moisture, low-temperature lubricant, corrosion, and service interval assumptions before sample quote. | Plan Prototype Validation |
| Phase | Engineering / QC Checkpoint | Buyer Output |
|---|---|---|
| Requirement baseline | Robot mass, leg geometry, joint axis, gait profile, rated torque, peak torque, and landing shock assumptions; Candidate reducer envelope, output bearing support, cable route, sealing target, and actuator housing drawing. 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 | Separate walking, trotting, jumping, landing, stumble, collision, stall, and emergency-stop torque cases. Review duty-cycle heat, lubrication, sealing, corrosion exposure, ingress risk, and maintenance interval with the reducer shortlist. Record open issues before sample cost and lead time are frozen. | A reducer shortlist and issue log for Quadruped Robot Joint Cycloidal Reducer. |
| Prototype or incoming validation | Measure landing shock case and duty-cycle heat against the agreed method. List jump, landing, stumble, collision, and emergency-stop cases as separate RFQ rows. | Inspection and test evidence with pass/fail limits, measured values, and revision actions. |
| Batch control and export readiness | Field environment ignored: 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.
Quadruped joints experience landing, stumble, and field-service loads that are different from a bench robot arm or ordinary cobot axis.
Yes, but sealing, lubrication, corrosion exposure, shock load, and maintenance interval must be included in the first review.
Send robot mass, joint axis, leg geometry, gait profile, peak events, envelope drawing, backlash target, and sample test plan.
Program Route
Quadruped Robot Joint 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.

Include ratio, torque, backlash, interface drawings, quantity plan, and destination terms.
