Blank & datum preparation
Turning establishes the bore, faces, shoulders and reference diameters used by later gear and spline operations.
MANUFACTURING & QUALITY
Sun Gear Manufacturing & Quality
The manufacturing route follows the drawing: blank preparation and turning, tooth generation, heat treatment, optional finishing, spline/shaft machining and inspection as required.
Tooth GenerationHeat TreatmentInspectie
Process planning around the part requirement
Not every sun gear needs every operation. The process should be selected from the drawing and duty.
Gear cutting
Hobbing or shaping can be used for external tooth generation depending on geometry, access and required process.
Spline / shaft features
Internal or external spline, shaft journals, threads, keyways and retention features are machined to the controlled drawing.
Warmtebehandeling
Material and hardness requirements are applied according to the drawing and application duty; case requirements should be stated explicitly.
Finishing
Grinding or other finishing is used when the drawing requires tighter tooth quality, runout or surface-finish control.
Inspectie
Inspection can include tooth thickness/span/over-pin measurements, runout, profile/lead data and interface dimensions as specified.
Inspection should match the risk
A dimensional report is useful only when it covers the characteristics that control assembly and mesh. For replacement gears, bore or spline fit, tooth thickness, runout and mating geometry usually deserve more attention than cosmetic measurements.
Tell us which records must accompany the shipment so the inspection plan is agreed before production.
Typical process flow for a custom sun gear
Blank & datum preparation
Machine the reference surfaces that will control later tooth and interface operations.
Gear & interface machining
Generate external teeth and machine bore, spline or shaft features to the planned datum scheme.
Warmtebehandeling
Apply the controlled hardness/case route with allowance for distortion and final finishing.
Finishing & inspection
Finish critical teeth or bearing/interface surfaces and verify the characteristics required by the drawing.
Praktische controlepunten voor kopers
| Onderwerp | Kopersadvies |
|---|---|
| Inspection is selective | Measure the characteristics that protect function rather than adding generic paperwork. |
| Heat-treatment effects | Plan stock and datum recovery before hardening when post-treatment finishing is required. |
| Integrated shaft risk | Long shaft parts can need extra straightness/coaxiality attention after treatment. |
| Packaging is part of quality | Protect finished teeth, splines and bearing seats from corrosion and metal-to-metal contact. |
