A gear shaft combines tooth geometry, bearing or locating surfaces and shaft features in one component, so the manufacturing plan must coordinate material condition, gear processing, heat treatment and datum control.\u003c\/p\u003e\n\u003ch3\u003eVerified component specification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 20CrNiMoA or 8620H alloy steel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStarting form:\u003c\/strong\u003e Hot-forged blank followed by machining.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear quality:\u003c\/strong\u003e Grade 9 is stated for this component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat treatment:\u003c\/strong\u003e Carburizing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface hardness:\u003c\/strong\u003e At least HV 700.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore hardness:\u003c\/strong\u003e HRC 30–45.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase depth:\u003c\/strong\u003e 0.7–1.17 mm.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eManufacturing process\u003c\/h3\u003e\n\u003cp\u003eThe project begins with review of the released drawing, gear data, material standard, datum structure and critical interfaces. A hot-forged blank provides the starting form. Machining and gear processing are then planned with sufficient allowance for the specified carburizing cycle and required final condition. The exact order of turning, gear cutting, heat treatment and finish operations is confirmed from the drawing and purchasing specification.\u003c\/p\u003e\n\u003ch3\u003eCarburizing and hardness requirements\u003c\/h3\u003e\n\u003cp\u003eThis component calls for carburizing with surface hardness of at least HV 700, core hardness of HRC 30–45 and case depth of 0.7–1.17 mm. The RFQ should identify the applicable hardness test method, case-depth definition, test location and any drawing-specific acceptance rules. These details allow the heat-treatment and inspection plan to be aligned before production.\u003c\/p\u003e\n\u003ch3\u003eGear and dimensional inspection\u003c\/h3\u003e\n\u003cp\u003eInspection follows the approved drawing and can cover gear geometry, Grade 9 requirements, runout, datums, shaft diameters, functional interfaces, surface hardness, core hardness and case depth. Required material certificates, heat-treatment records, gear inspection reports, dimensional reports and traceability should be listed in the inquiry.
