radial and axial run out of girth gear in kiln consequences

HAVEC - Girth Gear Monitoring System (GGMS)

As the excessive severe vibrations on the girth gear station very often occurs periodically, the main goal is to locate the cause of the problem. The measurements of both parameters’ axial and radial run-out are performed and the period of higher deviations is recorded. Then all the production and kiln condition parameters can be collected.

The causes of rotary kiln girth gear vibration

The rotary kiln girth gear has a large outer diameter, with a radial yaw and other factors, and the top clearance is 0.28 times the modulus plus 0.5-1 mm. At the same time, the radial runout and the axial yaw is no more than 2mm after the large girth gear finishes installation.

KILN MONITORING Dispelling myths in kiln mechanics

The axial run-out can be measured during normal kiln operation. To do so, contactless sensors are placed at one side of each tyre and changes in distance are collected and analysed. To measure the roundness and the above-mentioned straightness of the kiln, a distance laser sensor is placed beside the kiln from where it measures the deformation.
