Penerangan
A heavy-duty spiral bevel gear pair should be reviewed from the complete operating duty. Peak load, continuous load, shock events, reversals, bearing support and lubrication can all matter to material and process decisions. The exact geometry remains drawing-specific.
Best starting point: A project where load spectrum, shock, starts/stops or support stiffness make the duty more demanding than a simple nominal-torque description.
What this product family is designed to solve
Calling a gear “heavy-duty” does not create a technical specification. The RFQ needs the actual duty and the assembly that supports the pair. That information is more useful than an unsupported performance label.
Use this page when load and service duty are the dominant questions. If the main requirement is a ground tooth finish, start with the ground set; if the project is replacing an old heavy pair, use the replacement page so identification is addressed first.
Specification and RFQ table
For heavy-duty spiral bevel gear pair, 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. |
Contact and support conditions matter under load
Material, heat treatment and tooth finishing should be selected against the design requirement and load context. The housing and bearing system also need enough stiffness to hold the intended position. Inspection is then agreed around the dimensions and tooth-related criteria that matter to the machine.
The technical visual for heavy-duty spiral bevel gear pair 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
Mating member
Confirm which gear mates with the component and whether both members are included in the supply.
Datums & mounting
Show the surfaces and axes that control mounting distance, shaft position and backlash.
Laluan bahan
State controlled material/heat-treatment requirements and identify features that need secondary machining.
Penerimaan
List the dimensional, tooth-quality, runout or contact checks that are required for release.
Typical application fit
Lifting mechanisms, heavy industrial gearboxes, power-transmission machinery and other assemblies with shock, high load or demanding duty cycles.
Application duty should be sent with the drawing whenever it can change the material route, tooth finishing, support assumptions or inspection requirement.

Frequently asked questions
Can I order only one member of the pair?
For heavy-duty spiral bevel gear pair, 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 heavy-duty spiral bevel gear pair 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 heavy-duty spiral bevel gear pair 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 heavy-duty spiral bevel gear pair 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.
Perancangan komersial untuk RFQ anda
Untuk perancangan permintaan sebut harga, MOQ adalah fleksibel dan bergantung pada bentuk produk, laluan pemprosesan dan nilai pesanan keseluruhan. Projek baharu yang sesuai boleh disemak untuk 1–5 sampel barang pada harga sampel. Model yang berbeza boleh digabungkan apabila jumlah pesanan mencapai kira-kira USD 1,500. Pesanan 1–2 barang juga boleh dipertimbangkan, biasanya pada kos unit yang lebih tinggi kerana persediaan dan pemeriksaan diagihkan kepada kuantiti yang sangat kecil.
Untuk permintaan sebut harga, perancangan penghantaran, tempoh masa biasa adalah 10–25 hari bekerja untuk alat ganti standard, 20–45 hari bekerja untuk komponen tersuai dan 45–120 hari bekerja untuk peralatan atau pemasangan jenis projek. EXW, FOB, CIF dan DAP biasanya disokong; FCA, CFR, CPT, CIP dan DDP boleh dibincangkan untuk penghantaran dan destinasi tertentu.
