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 ...
Open Gear drives are very common in the raw materials industry. The girth gear drives that are used in tube mills, coolers, washing drums, kilns, calciners and other machines have to transmit enor-mous torques‚ i.e. often up to 50,000 Nm. It is only natural that this kind of force subjects the gear wheels to very high stresses.
Short Description: Gear ring Weight: 10~35T Applicable devices: rotary kiln, ball mill, tube mill Application: Cement, building material, metallurgy etc. Customizable or not: Yes Product introduction Gear ring is the main part of rotary kiln and ball mill which has to run for a long time, therefore, there is high quality requirement for gear ring in production.
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.

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.
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 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
