Description
Ground spiral bevel gears require more than adding a grinding operation to a normal gear. The datum scheme, pre-grind geometry, heat treatment, grinding allowance and final inspection have to be coordinated so the tooth finish is produced relative to stable references.
Best starting point: A matched pair where the ordered configuration specifically requires a ground tooth finish, tighter finished-tooth control or a coordinated post-heat-treatment finishing route.
What this product family is designed to solve
The ground route is most useful when it corresponds to a real drawing or performance requirement. It should not be selected only because “ground” sounds premium; the rest of the assembly still has to hold the pair at the intended mounting position.
Compared with a cut-tooth set, the manufacturing sequence and inspection plan usually need more explicit control after heat treatment. Compared with a generic custom set, the ground configuration narrows the process choice but does not remove the need to define pair geometry.
Specification and RFQ table
For ground 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. |
The process route changes before the final tooth finish
A typical route establishes the blank and datum surfaces, cuts the gear to the planned condition, applies the specified heat treatment and then finishes the tooth surface by grinding. Final interface work and inspection must respect the surfaces used to locate the gear during grinding.
The technical visual for ground 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
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.
Material route
State controlled material/heat-treatment requirements and identify features that need secondary machining.
Acceptance
List the dimensional, tooth-quality, runout or contact checks that are required for release.
Typical application fit
Precision machinery, selected machine-tool drives, controlled industrial gearboxes and other assemblies where the drawing calls for a ground tooth finish or a defined finished quality level.
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 ground 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 ground 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 ground 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 ground 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.
Commercial planning for your RFQ
For request a quote planning, MOQ is flexible and depends on product form, processing route and overall order value. Suitable new projects may be reviewed for 1–5 sample pieces at sample pricing. Different models can be combined when the order total reaches about USD 1,500. Orders of 1–2 pieces can also be considered, usually at a higher unit cost because setup and inspection are spread across a very small quantity.
For request a quote delivery planning, typical 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 specific shipment and destination.
Send the gear pair, drawing and duty in one RFQ.
The more clearly the mating relationship and assembly datums are defined, the faster the configuration can be reviewed.
