By deforming a profile, at a constant angular speed of the pinion, a slight angular delay can be observed in the dale areas of the girth gear as well as an adjustment in the hill areas. Following this theory, irregular movements are generated between the pinion and the girth gear, and therefore also vibrations and accelerations.

Figure 5 - Traditional Girth, pinion planetary gearbox kiln drive A recent installation for a 2500 MTD clinker plant uses a 2 pier support design kiln having a diameter of 13.6 ft and a length of 157 ft and is powered by a conventional girth gear and 2 x 335 hp DC drives.

The spray bar should be set at a 30-degree angle to spray the open gear lubricant onto the drive or loaded side of the pinion or girth gear. Setting the spray angle at 30° (as shown in Figures 5.) will achieve a very good distribution of the lubricant in an upward or downward direction, always to the load-carrying tooth flank.

mill pinion and girth gear. In most of the instances, the above maintenance techniques have been adhered to and the failure mode can therefore not be explained. Common practice is then to turn the girth gear around on the mill and run it on the back flank. In order to maintain alignment of the girth gear and mill

A gear is a wheel with teeth around its circumference. Gears are usually found in sets of two or more, used to transmit rotation from the axis of one gear to the axis of another. The teeth of a gear one one axis mesh with the teeth of a gear on another, thus creating a relationship between the rotation of the two axes.

Table 7-2 Commonly used diametral pitches . Instead of using the theoretical pitch circle as an index of tooth size, the base circle, which is a more fundamental circle, can be used.The result is called the base pitch p b, and it is related to the circular pitch p by the equation (7-8) 7.5 Condition for Correct Meshing. Figure 7-5 shows two meshing gears contacting at point K 1 and K 2.
