9.3.13. Adjustment of bearings of rotary knotsDesign of rotary knot
|
|
Centering of the rotary lever (1) |
|
|
Measurement of size of a gap "And" in the top rotary knot |
|
|
The scheme of rotary assembly for calculation of thickness of adjusting washers |
|
|
- Remove a sharnirny casing assembled with a power shaft (see. Section Removal and installation of power shafts of the forward bridge).
- Fill in a sleeve of a case of the bridge the corresponding directing ring from a special remnabor, - the ring should without any люфта nestle on a holder of the bearing bearing.
- In case of need center a center punch the rotary lever (1).
- Establish the top bolt of an axis of turn of a wheel (2) with a 2-millimetric remote ring (3) and without an adjusting washer (4).
|
|
The bottom bolt in the last five millimeters in a tightness is planted in assembly of a sharnirny casing (5) therefore before measurement of adjusting washers between it and an internal holder of the bearing it is necessary to establish a remote ring in thickness of 6 mm. One more ring in thickness of 4 mm should be planted between the rotary lever and a sharnirny casing. |
- Plant a bolt in the lever so completely to choose taking place люфт the bearing of rotary knot.
- For a bearing usadka повращайте sharnirny casing in different directions.
- With the help щупа lezviyny type measure a gap "And" between a casing (5) and a bolt (2), then by a remote ring (6) define a gap "In" between a casing (5) and the rotary lever (1), - write down results of measurements.
- Settle an invoice thickness of adjusting washers according to the following scheme:
Top rotary knot
Gap "And" = 1.30 mm
Adjusting ring = 2.00 mm
Bearing pretightness = 0.15 mm
Settlement thickness of an adjusting washer = 2.00 – 1.30 + 0.15 = 0.85 (mm)
Bottom rotary knot
Gap "In" = 1.10 mm
Difference of thickness of remote rings = 6-4 = 2.00 (mm) (see the remark above)
Bearing pretightness = 0.15 mm
Settlement thickness of an adjusting washer = 2.00 – 1.10 + 0.15 = 1.05 mm
- Remove directing ring and establish into place assembly of a sharnirny casing in a power shaft (see. Section Removal and installation of power shafts of the forward bridge).
- Further installation is made as it should be, the return to an order of dismantle of components.
