1.1 this practice describes a two-part procedure for electromagnetic evaluation on gear teeth on mill and kiln gear drives and pinions. the first part of this practice details the ability to detect 100 % of surface-breaking discontinuities in the flank and root area on both the drive side and non-drive (coast) side of the gear tooth using an eddy current.
A dial gauge e is placed at the midpoint of girth gear tooth width. the micrometer pointer is to be vertically measured to measure the radial runout of girth gear; a dial gauge a is placed on the end face of the girth gear to measure the end face runout of the girth gear; two dial gauges b and c are respectively placed at the shoulder of the ball mill trunnion and separated by 180 , to.
According to the installation procedure, after the large girth gear is assembled to the cylinder flange, the gap and the tooth pitch at the interface of the two halves of the girth gear should first be met, and then the radial runout and end face runout value of the large girth gear should be detected. if it is out of tolerance, it should be adjusted to ensure that it meets the technical.
