Check of a condition of a cranked shaft

Designation on a forward part of a cranked shaft

1 — a company Emblem
2 — the model Name
3 — check Date

4 — the Control category of automatic measuring system
5 — the Radical neck of a cranked shaft
6 — Width of the established loose leaf

Dimensional characteristics of a cranked shaft are presented in Specifications. Designation on a forward part of a cranked shaft is presented on сопр. illustrations.

Measurement of the sizes of necks of a cranked shaft and installation of new loose leaves

 PERFORMANCE ORDER

1. Remove a cranked shaft and establish covers of radical bearings of a cranked shaft and tighten them to 30 Nanometers.

2. Measure diameter of an opening under the radical bearing and diameter of a radical neck.
3. Selection of loose leaves is made as follows:
Diameter of an opening under the radical bearing (62.51 mm) - Diameter of a radical neck (57.95 mm) = 4.55 mm - the Radial gap (0.04 mm) = 4.51 mm/2 = Thickness of the loose leaf (2.25 mm).
On the basis of results of calculation the top loose leaf the "dark blue" and bottom loose leaf "dark blue" (gets out see. Specifications).
4. Nominal rates of working gaps and axial люфтов radical bearings of a cranked shaft make: 0.030-0.045 mm and 0.100-0.250 mm respectively.
5. The working gap in shatunny bearings makes 0.020-0.050 mm.
6. The final sizes and designation of openings under radical necks of a cranked shaft are specified in Specifications.
