||1 – the surface of fastening of a bent shaft to a flange;
2 – surface of fastening of coupling;
3 – a basic surface of the conducted clutch plate;
And – the radius on which the beating of a surface 2 is checked;
In – the radius on which the beating of a surface 3 is checked
To check a condition of a gear wreath; in case of damage of teeths to replace a flywheel.
The flywheel surfaces interfaced to a bent shaft and to the conducted clutch plate have to be without scratches, zadir and to be absolutely flat.
If on a working surface 3 flywheels under the conducted clutch plate are available scratches, it is necessary to pierce this surface, removing a layer of metal no more than 1 mm thick. Then to pierce a surface 2, maintaining the size (0,5 ± 0,1 mm) and providing parallelism of surfaces 2 and 3 concerning a surface 1.
The allowed not parallelism measured on extreme points of surfaces 2 (on radius And) and 3 (on radius In), should not exceed 0,1 mm.
To establish a flywheel on a mandrel, aligning it on a landing opening with the emphasis on a surface 1 and to check a beating of surfaces 2 and 3. On radiuses And yes In the indicator should not show the beats exceeding 0,1 mm.
