1.1.4. Check and adjustment of a tension of poliklinovy belts
|
|
|
|
1. Check a condition of a poliklinovy belt and its arrangement on pulleys.
|
|
1. Check correctness of an arrangement of edges of a poliklinovy belt in flutes of pulleys.
2. If at work poliklinovy the belt publishes extraneous noise, check a belt on lack of wear and damages, and also working surfaces of pulleys. Also check the deflection of a belt defining its tension. |
|
|
|
2. By the special device measure a tension of a driving belt. In the absence of the special device check a belt tension, having pressed on it effort of 100 N in a place located on identical removal from pulleys and measure a belt deflection. |

The tension of a belt should be measured precisely on the center between pulleys.
When the new belt is established, regulate a tension to the average value given in the column "New".
The belt which was in the use considered the belt which has worked on the engine more than 5 mines and its tension it is necessary to regulate to the average value given in a column
At adjustment of a tension of the belt which was in the use or the belt which has worked on the engine more than 5 mines it is necessary to regulate its tension to the average value given in a column "Being in the use".
At periodic surveys it is necessary to be guided by the column "Check".

Tension measurement by the special device of type A
|
|
At measurement of a tension of a poliklinovy belt the device should not concern other elements of the engine. |
Tension measurement by the special device of type B
|
|
|
1. At measurement be convinced that turned the button of repeated installation in the arrow direction to establish an arrow of the device in an initial condition.
|
|
2. After removal of the device from a belt of the shooter of the device will still specify a belt tension. |
