Description

Big Gear Ring, Big Tooth Ring, Big Ring For Mining Machine Mill Girth Gear

1. Technical requirements of large gear ring for mill girth gear

(1) The surface pretreatment before quenching is normalized, and the hardness should be HB210~250; Mechanical properties are strength limit Rb690MPa, yield limit Rs490MPa, elongation d511%, area reduction w25%, impact toughness value Ak30J. Tooth induction hardening, hardness of HRC50~55; Effective hardening depth 3~5mm.

(2) Ultrasonic inspection shall be carried out on the whole, and the internal quality shall meet the secondary requirements stipulated in GB7233-87 standard; Gear tooth and transition fillet magnetic particle inspection, quality should meet GB/T9444-88 standard requirements.

(3) Uncast rounded corners R5~R10.

(4) Chamfering of both ends and edges along the tooth width. Big gear ring by two half gear ring connected with high strength bolts into a whole gear ring, the joint surface must be in the center of the tooth bottom.

2. Product parameters of big ring for mill girth gear

The big gear ring

⑴GS42CrMo4 alloy cast steel (enterprise standard) HB 220 ~ 240

The half structure, Y type plate.

(3) oblique tooth.

(4) Reasonable sealing and alignment structure.

⑴ Outside refining of molten steel furnace (argon blowing and R-H vacuum treatment).

(2) The special cold mold sand hanging technology is adopted to ensure the density of casting and tooth.

(3) Normalizing treatment (proprietary technology) to ensure tooth surface hardness.

(4) After rough hobbing, release aging, repair the joint surface, and then fine rolling

⑸ homemade hob precision hobbing.

⑴ Mechanical properties and chemical composition of casting blank (internal control standard).

(2)The ultrasonic crack detection after rough machining.

⑶ half finishing, finishing ultrasonic inspection and magnetic particle inspection.

(4) Tooth surface magnetic particle inspection, hardness inspection.

⑸ Check tolerance of tooth profile.

⑹ No-load test of general assembly before delivery, check the meshing accuracy of large and small gears.
