DMGH18 DMGH22 DMGH-25.4 DMGH2-30. • Compact and efficient drive. • More effective use of the girth gear. • Perfect load distribution across the entire girth gear width. General description. The "Girth gear unit" is a load¬ sharing helical gear unit for driving a tubular mill via a girth gear…
Optimum contact pattern for the highest loads. Particularly innovative are the direct meshing FLENDER girth gear units (DMG2). This gear unit type was developed for driving tube mills with girth gears. Here, the gear unit forms a single unit with the girth gear with which it meshes directly.
CHAENG girth gears are applied to the Xinjiang Tianshan Group, Henan Meng Group, and other well-known domestic and foreign cement enterprises, for the normal operation of ball mill and rotary kiln. CHAENG customized for the Turkish customers a large girth gear with diameter of 7.3 meters and made up of GS34CrMo4 material, and received customer ...
Girth gears are divided into two basic categories; tangential spring mounting and flange mounting. Flange-mounted large gears are the more common of the two, and are most commonly used in "cold" processing equipment, such as semi-automatic grinding (SAG) mills and ball mills used in the mining and cement industries.
Gear cutting of a split girth gear for a cement mill having an input power of 2200 HP 5. Separate mill A: Damage to mill cylinder, neck or stub endanger girth gear and pinion. Repairs entail extra work for girth gear dismantling. B : Damage to mill cylinder cannot endanger gear teeth. Mill repairs do not entail gear dismantling. KAANU FAC TU RE 6.
Even, smooth operation of the kiln and optimal contact pattern with the pinion is achieved by mounting the girth gear on the kiln shell using tangential springs. The centered action of the girth gear is adjustable. Feel free to create friction. Alternatively, it's possible to transmit the drive torque from the rollers to the tire.
The girth gear driving pinion ends up getting aligned to the reduc-er, causing a misalignment issue between the girth gear teeth and the driving pinion teeth (Fig. 1). – Proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kiln/mill; center line of the driving pinion is aligned to the center line
Girth gears fall into two basic categories; flange mounted and tangential spring mounted. Flange-mounted girth gears, the more common of the two, are most frequently utilized in "cold" processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries. By current stan-dards, girth ...
Erection of a ball mill (double drive, cement mill) OPEN GEAR: ROTARY DRUM DRIVES /02 Position of pinions and girth gear on a ball mill Girth gear Outward pinion Inward pinion OPEN GEAR: ROTARY DRUM DRIVES 02. ... The contact between a gear set's active flanks is called « hertzien ». The theoretical contact area is limited to one generator.
Optimum contact pattern for the highest loads. Particularly innovative are the direct meshing FLENDER girth gear units (DMG2). This gear unit type was developed for driving tube mills with girth gears. Here, the gear unit forms a single unit with the girth gear with which it meshes directly.
The even, smooth operation of the kiln and optimal contact pattern with the pinion is achieved by mounting the girth gear on the kiln shell using tangential springs. The centered action of the girth gear is adjustable. One special feature of the gear drive, as a single drive with two pinions, is that it can operate with only one main motor.
The Wotan cement factory in Üxheim-Ahütte in the Eifel region of Germany had ordered a replacement girth gear made of cast steel G34CrMo4 and a replacement pinion made of forged 42CrMo4 from an Eastern European supplier for their cement mill no. 2 (diameter 3.2 m, drive power 1600 kW). After startup and commissioning with these new components ...
