Between above to dehisce, then increase the thickness of the adjust pad of bearing；So that on shaft coupling (1) and reference axis in adjustment axis
Shaft coupling (1) it is coaxial.
2. shafting installation aligning method as claimed in claim 1, it is characterised in that：Step 1) described in measurement apparatus use two
Individual dial gauge, i.e. the first dial gauge (3) and the second dial gauge (4)；
Radial missing a on the measurement vertical directionIt is perpendicular, radial missing a in horizontal directionWater, the end face on vertical direction it is inclined
Poor SIt is perpendicularAnd the end face deviation S in horizontal directionWaterComprise the following steps：
A, the first dial gauge (3) and the second dial gauge (4) be installed on dial indicator holder (2)；
Any one in shaft coupling (1) on b, the shaft coupling (1) that dial indicator holder (2) is arranged on reference axis and conciliation axle can
With on the shaft coupling (1) of rotation；
C, rotation shaft coupling (1) cause the first dial gauge (3) to be located at the extreme higher position of vertical direction, and the position is set into 0 ° of position
Put, the radial missing a of detection now1, then edge is rotated clockwise or counterclockwise to 90 °, 180 °, 270 ° of positions detects successively
To a2、a3、a4；Similarly pass through the end face deviation at 0 ° of the second dial gauge (4) detection, 90 °, 180 °, 270 ° of positions：S1、S2、S3、
S4；
After d, dial gauge are rotated by 360 °, a is arrived according to detection1、a2、a3、a4、S1、S2、S3、S4；Whether checking shaft coupling (1) accords with
Close technical requirements；
If：|a1|+|a3|=| a2|+|a4|, | s1|+|s3|=| s2|+|s4|, and radial missingWithLess than end
Face deviation | S1-S3| and | S2-S4|, while less than defined technical requirements, then carrying out step e；Otherwise shaft coupling (1), weight are changed
Multiple step b to d；
E, a by detecting1、a2、a3、a4Calculating is obtained：
Radial missing on vertical directionRadial missing in horizontal direction
Pass through the S detected1、S2、S3、S4Calculating is obtained：
End face deviation S on vertical directionIt is perpendicular=| S3-S1|；End face deviation S in horizontal directionWater=| S4-S2|。
