Description
A custom spiral bevel gear set is built around project-specific geometry rather than a public stock table. The useful definition includes both members of the pair, the axis relationship, tooth data, mounting datums, interfaces and the manufacturing/inspection requirements that are actually controlled.
Best starting point: A new or controlled design where both members, the shaft arrangement and the acceptance criteria can be defined on drawings.
What this product family is designed to solve
This configuration is the broadest starting point when the drawing owns the geometry. It can support unusual ratios, interfaces or packaging, but every extra degree of freedom makes drawing control more important.
Choose this page when geometry is unique or not yet tied to a legacy sample. If the tooth finish is specifically ground, the Ground Spiral Bevel Gear Set page gives a more focused process discussion.

Specification and RFQ table
For custom spiral bevel gear set, exact numerical values are confirmed for the ordered configuration. The table below identifies the drawing and enquiry fields that need explicit control.
| Selection item | Configuration | RFQ note |
|---|---|---|
| Pair identity | Matched spiral bevel gear pair or project-specific single component | Confirm the mating member and driving relationship. |
| Shaft angle | Project-specific | Show the axis relationship or assembly drawing. |
| Ratio / tooth counts | To drawing or RFQ | Provide both tooth counts when known. |
| Module / diametral pitch | To drawing or RFQ | Do not estimate from outside diameter alone. |
| Pressure angle | Confirm for ordered configuration | Use the drawing or reliable legacy data for replacement work. |
| Spiral angle & hand | Confirm for ordered configuration | Identify right/left hand with a defined viewing convention. |
| Mounting distance / backlash | Project-specific | Provide housing datums and target range when controlled. |
| Bore / spline / shaft interface | To drawing or sample | Include keyway, spline standard, journals and datum requirements. |
| Material / heat treatment | To drawing or project review | State mandatory grade, hardness or case requirements if controlled. |
| Tooth finish / quality | To drawing or project review | State cut/ground requirement and the acceptance standard or inspection criteria. |
Define the pair as one system
The manufacturing route is selected from the drawing. Blank and datum machining should create stable references for gear cutting and later finishing. Heat treatment and tooth finishing are then planned so the final inspection uses the same controlled datums.
The technical visual for custom spiral bevel gear set is a discussion aid for component relationships. The controlled production drawing and approved quotation remain the dimensional definition for the order.

Interfaces and assembly checks
Typical application fit
New machinery, compact right-angle drives, special gearboxes, automation mechanisms and any assembly where a controlled drawing defines the matched pair.
Application duty should be sent with the drawing whenever it can change the material route, tooth finishing, support assumptions or inspection requirement.
Manufacturing and inspection sequence
Review
Confirm drawing revision, pair identity, open questions and acceptance-critical features.
Plan
Define blank, datum machining, gear cutting, heat treatment and finish sequence.
Finish
Complete tooth and interface finishing according to the ordered route.
Inspect
Check the dimensions and gear-related criteria agreed for the configuration.
What to include in the enquiry
| RFQ group | Recommended detail |
|---|---|
| Technical definition | Current drawing, pair reference, ratio/tooth counts, hand and axis relationship |
| Assembly | Bore/shaft/spline, bearings, housing datums, mounting distance and backlash if controlled |
| 의무 | Speed, torque/load spectrum, reversals, shock, environment and lubrication |
| 품질 | Material, heat treatment, tooth finish, tolerances and inspection records |
| 광고 | Prototype and repeat quantity, destination, timing target and preferred trade term |
Frequently asked questions
Can I order only one member of the pair?
For custom spiral bevel gear set, supplying one member can be reviewed when the mate is fully defined. If the existing mate is unknown, send its drawing, measurements or physical gear before releasing a single component.
Can a worn sample be copied directly?
A worn custom spiral bevel gear set sample can support identification, but wear should not be treated as original geometry. Legacy drawings, an unused mating member and assembly measurements provide a stronger reconstruction basis.
Do I need to choose material and heat treatment before the RFQ?
When the custom spiral bevel gear set design controls material or heat treatment, state the exact requirement. If those items are open, describe duty and mark them for selection review rather than borrowing a grade from another gear.
How are small sample quantities handled?
Small samples of custom spiral bevel gear set can be reviewed for suitable new projects. Separate prototype quantity from expected repeat demand so setup, inspection and later production are planned against the correct volume.
견적 요청서(RFQ)에 대한 상업적 계획 수립
견적 요청 시 최소 주문 수량(MOQ)은 제품 형태, 가공 방식 및 총 주문 금액에 따라 유동적입니다. 적합한 신규 프로젝트의 경우 샘플 가격으로 1~5개의 샘플 제품에 대한 검토가 가능합니다. 총 주문 금액이 약 1,500달러에 도달하면 여러 모델을 조합하여 주문할 수 있습니다. 1~2개 소량 주문도 가능하지만, 소량 주문에 대한 설정 및 검사 비용이 분산되므로 단가가 더 높을 수 있습니다.
견적 요청 시 납기 계획은 일반적으로 표준 부품의 경우 10~25영업일, 맞춤형 부품의 경우 20~45영업일, 프로젝트형 장비 또는 조립품의 경우 45~120영업일이 소요됩니다. EXW, FOB, CIF, DAP 조건이 일반적으로 적용되며, FCA, CFR, CPT, CIP, DDP 조건은 특정 선적 및 목적지에 따라 협의 가능합니다.
장비 쌍, 도면 및 부하 정보를 하나의 견적 요청서에 포함하여 보내주십시오.
결합 관계 및 조립 기준점이 명확하게 정의될수록 구성 검토 속도가 빨라집니다.
