12:13. Check of a radial and side beating of disks
|
Fig. 12.1. Surfaces of measurement of a beating of a disk: N – a radial beating; S – side beating
|
Fix a disk without tire on an axis of the balancing device. Establish a measuring tip of the arrow indicator at first on radial, and then on side internal surfaces of a disk on which the board of the tire (fig. 12.1) leans.
Slowly turn hands a disk of the balancing device, at the same time taking readings of the indicator. At the same time do not consider an indicator arrow deviation from local ledges or deepenings on a disk.
If the maximum value of a beating exceeds admissible limits, replace a disk.
NOTE
Maximum beating of a steel disk: N = 0,8 mm, S = 1,0 mm.
Maximum beating of a light-alloy wheel: N = 1,5 mm, S = 1,5 mm.
