Gear

Uses: Used for agricultural tractor gear transmission products, realizing speed change through gear transmission ratio; Features: It belongs to a typical gear part, the gear center is a spline mounting hole, the outer circle is an involute gear tooth, and the disk surface has bolt holes. For locking, the internal spline and gear have high dimensional accuracy, strength and hardness requirements; Process requirements: The blank is generally made of steel bar or forging. The main processes include: normalizing treatment-turning machining-drilling-milling gear-wire cutting internal spline-induction hardening internal spline, cylindrical gear and other processes; the main processing equipment has numerical control lathe, gear hobbing machine, machining center, induction hardening equipment. Key inspection items: spline, surface roughness, appearance, coaxiality, position and other items; Key inspection equipment: special spline inspection tool, gear measuring machine, large and medium-sized precision coordinate measuring machine;
