2.2.2. Tension of a maple belt
Cars without gear lath on an arm
Because of increase in power generation by the generator of alternating current, check of a tension of a maple belt became more important.
The following indicators have to be defined when checking a tension of a maple belt when pressing on a belt by a thumb.
Maple belt up to 1000 mm long, maximum deviation and:
new maple a belt – about 2 mm
maple the belt which was in operation – about 5 mm
Maple the belt is longer, than 1000 mm, the maximum deviation and:
new maple a belt – about 10 mm
maple the belt which was in operation – about 15 mm
The given values are valid for cars of all modifications.
Adjustment
PERFORMANCE ORDER |
1) weaken bolts |
2) move the generator outside so that to receive the required maximum size of a deviation |
3) tighten fastening bolts |
|
Cars with the gear mechanism
PERFORMANCE ORDER |
|
1) weaken bolts In, With and a hinged bolt of a support (it is not shown in the drawing) |
Prevention
Bolts of fastening have to be rather weakened that the generator could move freely under the weight.
|
2) pull maple a belt rotating a tension gear wheel In by means of a wrench |
3) a free hand check the maximum deviation of a belt under pressure of a thumb for a new belt the deviation has to be 8 mm for an old belt the deviation has to be 4 mm |
4) twirl or turn off a tension gear wheel to achieve a necessary deviation |
5) after that, tighten fastening bolts till the next moments of an inhaling: the bolt inhaling moment In: 35 N. of m. the bolt inhaling moment With: 20 N. of m. support bolt inhaling moment: 35 N. of m. |
