Machine duty
Explain reversing frequency, acceleration, inertia, positional repeatability, shaft support and service interval. These inputs help the quotation reflect the actual machine rather than an industry label.
Automation systems use intersecting-axis drives where packaging is tight and motion may reverse frequently. The gear pair must be considered together with inertia, bearing support, commanded motion and maintenance access.

In automated equipment, the gear set rarely works alone. Motor, coupling, bearings, shafts and the downstream mechanism all influence how reversal and torque are seen at the teeth. A useful RFQ describes that motion profile instead of treating the gear as a static catalogue item.
If the gear is part of a servo-driven mechanism, explain whether the downstream process depends on repeatable angular position or simply on power transfer. That distinction changes which inspection results are useful to the buyer.

| Review area | What to provide | Why it matters |
|---|---|---|
| Motion / duty | Reversing frequency, acceleration, inertia, positional repeatability, shaft support and service interval | Separates steady power transmission from reversing, shock or position-sensitive duty. |
| Gear pair | Gear + pinion identity, ratio/tooth counts and hand | Prevents one component from being reviewed without its mating geometry. |
| Mounting | Shaft arrangement, bearing support, housing datums and target backlash | Connects the manufactured part to the position it will hold in the assembly. |
| Environment | Lubrication, temperature and contamination context | Supports practical material, finish and service review without inventing machine-level claims. |
| Inspection | Drawing tolerances, tooth finish and required records | Defines what the buyer will use to accept the ordered configuration. |
Backlash that is acceptable in a continuous conveyor can be noticeable in a mechanism that changes direction repeatedly. Do not assume a generic backlash value; use the machine requirement and the mounting geometry that can actually maintain it.
Ground or custom pairs are a natural starting point for motion-sensitive mechanisms, while a miter set can suit compact 1:1 direction changes when the ratio and axis relationship are fixed.
If a robotic axis or automated positioning cell still has open geometry or duty inputs, mark those items for review. An explicit unknown is safer than filling the drawing with an assumed standard value.

View configuration →When the robotic axis or automated positioning cell drawing controls material or heat treatment, include the exact requirement. If those choices remain open, describe the duty and leave material/process selection for review.
Photos of the robotic axis or automated positioning cell help establish orientation and condition, but they do not define tooth geometry or mounting datums. Add the mating member, drawing data and measurements taken from controlled assembly references.
For the robotic axis or automated positioning cell, send the assembly information that controls shaft relationship, mounting datums and interfaces. Unrelated machine details can be omitted when they have no effect on gear selection or inspection.
For the robotic axis or automated positioning cell, separate prototype/sample quantity from expected repeat demand. This keeps tooling, inspection and production planning tied to the real purchasing stage.
The more clearly the mating relationship and assembly datums are defined, the faster the configuration can be reviewed.
MOQ is flexible by product type, manufacturing route and total order value. Suitable new projects may request 1–5 sample pieces at sample pricing. Mixed models can be combined when the order total reaches approximately USD 1,500. Orders of 1–2 pieces can be reviewed, although unit cost is normally higher.
Typical planning windows are 10–25 working days for standard parts, 20–45 working days for customized components and 45–120 working days for project-type equipment or assemblies. EXW, FOB, CIF and DAP are commonly supported; FCA, CFR, CPT, CIP and DDP can be discussed for the shipment.
