1 – оправка А.74107/2R;
2 – запорное a bearing ring;
3 – a plate of fastening of the bearing and маслоотражатель in gathering with a lining;
4 – basic ring А.74107/1R;
5 – полуось;
6 – the bearing;
7 – holder А.74107/4R
|
Effort check, with which выпрессовывается запорное a ring of the bearing of a semiaxis, by means of adaptation A.95601/R and динамометрического a key
1 – the indicator;
2 – полуось;
3 – adaptation A.95601/R; |
4 – динамометрический a key;
5 – the ball-bearing;
6 – запорное a bearing ring |
| PERFORMANCE ORDER |
| 1. Put vertically полуось, опирая its flange on a ring of 4 adaptations (А.74107/IR) (fig. of Zapressovka запорного rings of the bearing of a semiaxis see). |
| 2. Establish on полуось, preliminary connected among themselves two screws, маслоотражатель the bearing of a semiaxis and a plate of fastening of the bearing with a lining; establish the semiaxis ball-bearing. |
| 3. Insert new запорное a ring into a special holder 7, put in the furnace and warm up a ring, approximately to 300 ° With so that during the moment запрессовки on полуось, its temperature was 220–240 °. |
| 4. The zapornoe ring on полуось напрессовывайте оправкой 1 on a press, effort not above 58,8 КН (6000 кгс) so that an internal ring of the bearing has appeared clamped between запорным a ring and a semiaxis fillet. |
| 5. Having executed напрессовку, be convinced that the ring is not displaced under axial loading 19,6 КН (2000 кгс). For this purpose, полуось in gathering establish on adaptation A.95601/R (fig. effort Check with which выпрессовывается запорное a ring of the bearing of a semiaxis, by means of adaptation A.95601/R and динамометрического a key) and запорное a ring clamp in a special vice see. |
| 6. Put an indicator leg, with the price of division of 0,01 mm, to a semiaxis flange. After installation of an arrow of the indicator on «0» put the specified axial loading, creating динамометрическим a key the moment of a tightening 78,4–83,3 Н·мм (8–8,5 кгс·м) on the adaptation screw. The screw through a ball rests against a semiaxis end face. Thus, there should not be even the most minimum backlash between запорным a ring and an internal ring of the bearing. |
| 7. After removal of loading and at отвертывании the screw of the adaptation of the marksman of the indicator should return to zero position; it proves that there was no shift between запорным a ring and a semiaxis. If the arrow of the indicator does not come back in zero position, means запорное a ring was displaced and полуось in gathering it is necessary to replace new. |
