Measurement of the sizes of necks of a bent shaft and installation of new inserts
|
|
|
1. Remove a bent shaft and establish covers of radical bearings of a bent 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 inserts 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 = the insert Thickness (2.25 mm).
On the basis of results of calculation the top insert a "blue" and lower insert "blue" is chosen (see Specifications).
4. Nominal rates of working gaps and axial side plays of radical bearings of a bent shaft make: 0.030-0.045 mm and 0.100-0.250 mm respectively.
5. The working gap in conrod bearings makes 0.020-0.050 mm.
6. The final sizes and designation of openings under radical necks of a bent shaft are specified in Specifications. |
