wherein L 1it is the distance between the first fulcrum and shaft coupling (1);
4) reference axis invariant position is ensured, according to the Δ H obtained 1, Δ H 2Δ H n, regulate the thickness of the adjustment pad of first corresponding bearing in fulcrum to the n-th fulcrum place on regulating shaft;
If dehisce under between two shaft couplings (1) being, then reduce the thickness of the adjustment pad of bearing; If dehisce between two shaft couplings (1) being, then increase the thickness of the adjustment pad of bearing; Thus make the coaxial of the shaft coupling (1) on the shaft coupling on regulating shaft (1) and reference axis.
2. shafting installation aligning method as claimed in claim 1, is characterized in that: step 1) described in measurement mechanism adopt two dial gauges, i.e. the first dial gauge (3) and the second dial gauge (4);
Radial missing a on described measurement vertical direction perpendicular, radial missing a in horizontal direction water, end face deviation S on vertical direction perpendicularand the end face deviation S in horizontal direction watercomprise the following steps:
A, the first dial gauge (3) and the second dial gauge (4) are installed on dial indicator holder (2);
B, dial indicator holder (2) is arranged on the shaft coupling (1) on reference axis and reconciles in the shaft coupling (1) on axle on any one rotary shaft coupling (1);
C, rotation shaft coupling (1) make the first dial gauge (3) be positioned at the extreme higher position of vertical direction, this position are set to 0 ° of position, detect radial missing a now 1, then along clockwise or rotate counterclockwise 90 °, 180 °, 270 ° positions and a detected successively 2, a 3, a 4; In like manner detected the end face deviation of 0 °, 90 °, 180 °, 270 ° position by the second dial gauge (4): S 1, S 2, S 3, S 4;
After d, dial gauge rotating 360 degrees, arrive a according to what detect 1, a 2, a 3, a 4, S 1, S 2, S 3, S 4; Whether checking shaft coupling (1) meets technical requirement;
If: | a 1|+| a 3|=| a 2|+| a 4|, | s 1|+| s 3|=| s 2|+| s 4|, and radial missing with be less than end face deviation | S 1-S 3| with | S 2-S 4|, be less than the technical requirement of regulation simultaneously, then carry out step e; Otherwise change shaft coupling (1), repeat step b to d;
E, a by detecting 1, a 2, a 3, a 4calculate:
Radial missing on vertical direction radial missing in horizontal direction
By the S detected 1, S 2, S 3, S 4calculate:
End face deviation S on vertical direction perpendicular=| S 3-S 1|; End face deviation S in horizontal direction water=| S 4-S 2|.
