10.4.3. Determination of thickness of adjusting laying and its installation in the reducer case
|
|
1. Fix the indicator on a clamp and establish a measuring plate.
2. Install in "0" indicator with a 3-mm tightness on a measuring disk (051), - height of a measuring disk (051) is regulated. |
|
| 3. Establish an external ring of the roller bearing (46b) on an internal ring of the leading gear wheel (47) and establish a magnetic disk (052c). |
|
4. Insert the leading gear wheel into a measuring plate and measure height of the leading gear wheel with the conic roller bearing and a magnetic disk.
5. Define a difference between vysty "B1" and height "In". Write down the received value (for example 1.79 mm). |
| 6. Read the main deviation of "a" of the leading gear wheel ("+" or "-") and write down it (for example, +0.06 mm). |
|
| 7. Depending on a prefix ("+" or "-") value for the leading gear wheel is plused (if "+") or taken away (if "-"). |
| 8. Insert the measuring instrument (051b) into the reducer case. Screw it. |
|
| 9. Insert left (052e) (outside inside) and right (052d) (from within outside) measuring rings into the reducer case against the stop. |
|
10. Install the measuring device (052a) with a measuring finger in the measuring device (052), - the measuring finger is rolled in a measuring detail (052b).
11. Install a measuring detail (052b) in the measuring device and nullify the indicator with a 2-mm tightness. When tightening a bolt, the indicator has to be nullified. |
|
| 12. Insert the measuring device into the left opening in the reducer case. |

Measure distance of "A" between the regulator and the forward party of the measuring instrument
|
|
|
051b — the Measuring instrument
A1 — Distance between the regulator and the forward party of the measuring instrument
B1 — measuring instrument Height
M — the Center of a gear wheel |
|
|
|
|
1. Measure distance of "A" between the regulator and the forward party of the measuring instrument and write down indications with positive ("+") or negative ("-") the direction (for example, it is received - 0.01 mm and the negative direction). The positive or negative direction depends on rotation of the indicator. The direction of rotation, from neutral situation, counterclockwise defines the negative direction, clockwise - the positive direction.
2. Determine laying thickness: Distance between height of "B1" and height "In" = 1.79 mm + the Main deviation of "a" of the leading gear wheel (0.06 mm) = 1.85 mm + the Difference of "A1" between the regulator and the forward party of the measuring instrument (0.01 mm) = the laying Thickness (1.86 mm).
3. Remove the measuring device and measuring rings from a reducer. Remove the measuring instrument. Insert laying of a certain thickness into a reducer. |
