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. Establish in «0» indicator from 3-mm by a tightness on a measuring disk (051), - the height of a measuring disk (051) is regulated.

3. Establish an external ring of the roller bearing (46b) on an internal ring of a leading gear wheel (47) and establish a magnetic disk (052c).

4. Insert a leading gear wheel into a measuring plate and measure height of a leading gear wheel with the conic roller bearing and a magnetic disk.
5. Define a difference between vysty «В1» and height "In". Write down the received value (for example 1.79 mm).

6. Read the main deviation of "an" of a leading gear wheel («+» or «-») and write down it (for example, +0.06 mm).

7. Depending on a prefix («+» or «-») value for a leading gear wheel плюсуется (if «+») or is taken away (if «-»).

8. Insert a 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. Establish the measuring device (052a) with a measuring finger in the measuring device (052), - the measuring finger is rolled in a measuring detail (052b).
11. Establish a measuring detail (052b) in the measuring device and null the indicator from 2-mm by a tightness. At a bolt tightening, the indicator should be nulled.

12. Insert the measuring device into the left opening in the reducer case.

Measure «A» distance between a regulator and the forward party of a measuring instrument


051b — the Measuring instrument А1 — Distance between a regulator and the forward party of a measuring instrument В1 — measuring instrument Height M — the gear wheel Center

PERFORMANCE ORDER

1. Measure «A» distance between a regulator and the forward party of a 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 indicator rotation. The rotation direction, from neutral situation, counter-clockwise defines the negative direction, clockwise - the positive direction.
2. Define thickness of laying: Distance between the height «В1» and height "In" = 1.79 mm + the Main deviation of "an" of a leading gear wheel (0.06 mm) = 1.85 mm + the Difference «А1» between a regulator and the forward party of a measuring instrument (0.01 mm) = Thickness of laying (1.86 mm).
3. Remove the measuring device and measuring rings from a reducer. Remove a measuring instrument. Insert laying of a certain thickness into a reducer.
