Spur gears use straight teeth to transmit rotary motion between parallel shafts. Although the basic geometry is familiar, successful production depends on coordinating the tooth data, bore and hub features, datums, material condition, heat treatment and inspection method shown on the customer drawing.\u003c\/p\u003e\n\u003ch3\u003eEngineering information reviewed before quotation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Grade, delivery condition and governing material standard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear geometry:\u003c\/strong\u003e Module or diametral pitch, pressure angle, tooth count, helix angle if any, profile modification and required quality grade.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart geometry:\u003c\/strong\u003e Bore, hub, keyway, shoulders, mounting holes, faces and datum structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess requirements:\u003c\/strong\u003e Blank type, machining, gear cutting, heat treatment, finishing and any protected surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInspection:\u003c\/strong\u003e Gear measurement, runout, bore and face checks, sampling level and required reports.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eManufacturing process planning\u003c\/h3\u003e\n\u003cp\u003eThe process plan is created after the released 2D drawing and available 3D model are reviewed. Depending on the specification, the route can include preparation of the required blank, turning of the bore and hub features, gear cutting, specified heat treatment and finish operations. Jinhua Machinery does not apply one standard route to every spur gear; material, geometry, hardness, quality grade and annual volume determine the appropriate sequence and inspection points.\u003c\/p\u003e\n\u003ch3\u003eMaterials and heat treatment\u003c\/h3\u003e\n\u003cp\u003eMaterial and heat treatment must be taken from the customer specification. The inquiry should state the material grade, standard, initial condition, required hardness, case or through-hardening requirement where applicable, and any surface or coating requirement. If these values are not yet released, they should be identified as design inputs still requiring customer confirmation rather than assumed during quotation.\u003c\/p\u003e\n\u003ch3\u003eGear inspection and quality records\u003c\/h3\u003e\n\u003cp\u003eInspection planning can cover tooth geometry, specified gear quality, bore size, runout, tooth-to-datum relationship, face dimensions, surface condition and hardness where required.
