Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, a kind of OG fan coupler gap bridge cylinder centralising device, for the centering between OG fan coupler 1 and coupling device shaft coupling 5, this device is made up of cylinder 4 of passing a bridge, Magnetic gauge stand 3, dial gauge 2, fastening special bolt 6 and localization criteria bar 7, described gap bridge cylinder 4 comprises link bolt hole 8 and adjusting bolt hole 9, this link bolt hole 8 and described fastening special bolt 6 matched in clearance, and quantity is consistent with screw thread quantity on coupling device shaft coupling 5; Described adjusting bolt hole 9 is applicable to the shaft coupling of different size; Described Magnetic gauge stand 3 is fixed on gap bridge cylinder 4; Described dial gauge 2 frame is on OG fan coupler 1; Described fastening special bolt 6 coordinates coupling device shaft coupling 5 upper screwed hole; Distance between described localization criteria bar 7 location survey OG fan coupler 1 and coupling device shaft coupling 5, the length of this localization criteria bar 7 is greater than the distance between OG fan coupler 1 and coupling device shaft coupling 5; Described gap bridge cylinder 4 cylindrical and end face are metalworking face, and the circularity of this cylindrical and the circle at two ends are beated and beated consistent with the circularity of coupling device shaft coupling 5 cylindrical and the circle at two ends.During concrete enforcement as shown in Figure 3, the distance between two localization criteria bar 7 location survey OG fan couplers 1 and coupling device shaft coupling 5 is first used before centering, ensure the rich property catcher can installed after centering completes between two shaft couplings, and leave a certain amount of axial displacement value, as shown in Figure 4, when us with coupling device shaft coupling 5 for benchmark, by Magnetic gauge stand 3 frame on coupling device shaft coupling 5, by dial gauge 2 frame on gap bridge cylinder 4, rotate the data that coupling device shaft coupling 5 reads each point simultaneously, again by the fastening gap bridge cylinder 4 of fastening special bolt 6 leveling and adjusting, making the circularity of gap bridge cylinder 4 cylindrical and the circle at two ends beat after leveling and adjusting beats consistent with the circularity of coupling device shaft coupling 5 cylindrical and the circle at two ends, and will ensure the axiality between gap bridge circle 4 and coupling device shaft coupling 5 and perpendicularity, as shown in Figure 5, the Magnetic gauge stand 3 that installation two is symmetrical in gap bridge cylinder 4 radial direction, each installation dial gauge 2 in OG fan coupler 1 radial direction and end face, again with OG fan coupler 1 for benchmark rotates gap bridge cylinder 4, read the data of each end points of dial gauge 2, then the spacer thickness of adjustment coupling device four footing is calculated, by the set bolt of fastening adjustment coupling device four footing, the circularity of OG fan coupler 1 cylindrical and the circle at two ends being beated beats consistent with the circularity of gap bridge cylinder cylindrical and the circle at two ends, and the axiality between OG fan coupler 1 and gap bridge cylinder 4 and perpendicularity will be ensured.
