The specialized demands of a huge CITICIC Gear ring:
1) is pretreated just before normalizing surface hardening therapy, the hardness ought to HB210 ~ 250 mechanical overall performance are the greatest energy Rb 690MPa, yield tension Rs 490MPa, elongation D5 11%, reduction of location W 25% , impact toughness Ak 30J enamel induction hardened, hardness HRC50 ~ fifty five effective hardened layer depth 3 ~ 5mm.
two) general ultrasonic flaw detection, inside quality ought to meet two demands GB7233-87 standard demands tooth and fillet magnetic particle inspection, good quality should meet up with two needs GB/T9444-88 specifications.
three) Be aware the casting is not rounded R5 ~ R10.
four) Tooth chamfer at each ends and 1 45b.5) by two and a fifty percent ring gear tooth width of every single ring coupling along the edge of a total ring manufactured with high toughness bolts, blended with the tooth surface area have to be at the base center.
two huge ring equipment producing approach
2.1 of tough
Steel casting blank is presented by CITIC CZPT CZPT ry Co., Ltd. CZPT Forging plant, run by GB11352-89 regular specifies specifications for modeling in accordance to the casting method, smelting, casting, hit boxes, cleaning, dressing castings. During inspection and acceptance by the drawings and Technical needs for metal blank
Checks, in accordance JB/T6402-ninety two standards issued following acceptance
Down method.
two.2 roughing
Crossed by drawing and keep out allowance, alignment, connection, processing each inside and exterior the circle, combining experience milling, drilling and other processes.
two.3 Exploration injuries
All round ultrasonic flaw detection, inside good quality must satisfy the two requirements of GB7233-87 expectations.
2.4 normalizing pretreatment
Semi-ring pairs normalizing and tempering remedy, give a excellent business for subsequent area hardening push drawings deformation of the 50 % ring gear inspection soon after warmth therapy.
2.5 Machining
Very first two and a half ring is manufactured with large power bolts connecting the ring as a whole, the all round procedure by drawing a circle CZPT nei Wai enamel and upper and reduced finish, and then drawing and machining milling process needs.
two.6 Elimination of processing anxiety
The general ring annealed to get rid of pressure.
two.7 total ring surface hardening
IF alongside the alveolar tooth surface induction hardening, hardness HRC50 ~ fifty five, successful hardened layer depth 3 ~ 5mm.
2.8 Ultimate inspection
Initial, the detection frequency quenching, the hardness after tempering ring equipment cogging fulfills the specifications of the drawings CZPT ly, to detect whether or not the greatest outer diameter larger measurement D6944 as the deformation 3mm, the mechanical correction essential till experienced Thirdly, tooth and fillet magnetic particle inspection, quality must fulfill two specifications GB/T9444-88 standard needs Finally, in accordance to the drawings and complex specifications for closing inspection.

The effectiveness of a worm equipment transmission relies upon to a big extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have verified to be 25% to fifty% much more efficient than single-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear results in considerable friction and reduction of performance compared to other types of gears. Increase effectiveness with hardened and ground worm switch bronze worm gears.
