Mill Ring Gear
Mill Ring Gear heat treatment system can be recommended for normalizing at 850 C, quenching at 840 C, and tempering at 600 C, and the yield strength is more than 355MPa.
The ball Mill Ring Gear is usually adopted 45 steel, but according to the GB/T699-1999 standard, the tensile strength of C45 steel is 600MPa, the yield strength is 355MPa, the elongation is 16%, the section shrinkage is 40%, and the impact work is 39J. According to the 45 steel of GB/T699-1999 standard, the heat treatment system can be recommended for normalizing at 850 C, quenching at 840 C, and tempering at 600 C, and the yield strength is more than 355MPa. The hardness of No. 45 steel quenched and tempered is less than HRC28, which is soft and non abrasion resistant. After quenching, the hardness is greater than HRC55 and wear resistance is better.Mill Ring Gear is mostly equipped with large equipment such as dryer gear ring and ball mill gear ring.
Stainless steel, carbon steel, titanium alloy, high chrome, cast iron, bronze, ductile iron, brass, etc.

Mill Ring Gear Installation:
the end face of Mill Ring Gear and the end face of the hollow shaft flange must not be more than 0.15 millimeter while the ball mill gear and the cylinder are assembled, The radial runout of the top circle of the large gear shall not exceed 0.86 mm after the assembly of the large gear, and the base face runout shall not exceed 1.2 mm. The tooth side clearance of the size gear assembly should be 0.53-1.4 millimeter and two tooth. The contact area of the wheel shall not be less than 45% of the tooth height and 60% of the tooth width.
Tooth gear ring mainly is used in ball mill machine, rotary kiln , drum dryer, drum coating machine, grinding machine, sand washing machine, recreational equipment, oil refining equipment and other large-scale transmission machinery.
