Determination of thickness of adjusting laying and its installation in the reducer case

PERFORMANCE ORDER

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

PERFORMANCE ORDER

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.
