2.2.15.20. Measurement of a radial gap in radical bearings of a cranked shaft

Establish a cover of radical bearings and a cranked shaft.

Place pieces of the calibrated plastic wire from above on shaft necks, having arranged them along an axis.

Establish a cover of radical bearings and the block of cylinders.

Uncover radical bearings.

Fig. 2.168. Measurement of a radial gap in radical bearings

Measure a radial gap in radical bearings (fig. 2.168).

If the gap exceeds a maximum, replace the radical bearing, using the table of a choice of the radical bearing, or прошлифуйте a radical neck and establish the bearing of the increased size so that the specified gap was provided.

Normal gap: 0,019–0,035 mm

Maximum gap: 0,10 mm
