Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in attached drawings 1-4, the centering device for the diesel engine and the dynamometer using the integral supporting legs comprises a diesel engine 1, integral supporting legs 2, a diesel engine base 3, a dynamometer 4, connection high elasticity 5, a centering support 6 and the like.
The centering frame 6 comprises a centering bracket 65, a measuring bolt a63 and a measuring bolt b 64; wherein, the end part of the vertical long edge of the centering bracket 65 is arranged on the dynamometer 4, and the horizontal short edge of the centering bracket is arranged towards the diesel engine 1; a measuring bolt a63 which is in axial contact with the connecting high-elasticity 5 is arranged on the vertical long edge of the centering bracket 65 and is used for measuring the axial alignment error of the diesel engine 1; the horizontal short side of the centering bracket 65 is provided with a measuring bolt b64 which is in radial contact with the connecting high spring 5 and is used for measuring the radial alignment error of the diesel engine 1.
The specific working steps are as follows: before all centering work is carried out, the dynamometer 4 and the diesel engine base 3 are pre-centered in advance according to design size requirements.
Fixing a centering bracket 65 on a connecting flange 41 of a dynamometer 4, respectively installing a dial indicator a61 and a dial indicator b62 on the centering bracket 65 in the axial direction and the radial direction, rotating a rotating shaft of the dynamometer 4 connecting flange, recording the values of the dial indicator a61 and the dial indicator b62 in the axial direction and the radial direction at intervals of 90 degrees to obtain four radial measured values, slightly moving the diesel engine 1 by using a jackscrew device on a diesel engine base 3 according to the radially recorded values, and filling proper gaskets at the bottom of the dynamometer 4 according to the axially recorded values, wherein the purpose of adding the gaskets at the integral supporting leg 2 and the base 3 for centering is to keep the radial measured values and the axial measured values in the four directions as consistent as possible because the integral supporting leg 2 and the diesel engine 1 are connected for increasing the stability of the diesel engine 1. Since the diesel engine 1 is in a fixed state, the diesel engine 1 is ensured to be 0.2-0.3mm higher than the dynamometer 4 in the vertical direction of the radial direction, and the purpose is that the diesel engine 1 will descend after the diesel engine 1 is fixed by the fastening bolts a and b.
After the four measured direction values meet the process requirement values, a fastening bolt a7 and a fastening bolt b8 penetrate through the unthreaded hole 21 of the integral support leg 2, a torque wrench respectively tightens the fastening bolt a7 and the fastening bolt b8 to pre-tighten the diesel engine 1, then the fastening bolt a7 and the fastening bolt b8 are respectively tightened through pulling angles, after the angle pulling process, the angle pulling is carried out after the pre-tightening of another bolt is rechecked, when eight supporting points are connected to the fastening diesel engine 1, the supporting points are operated at each supporting point and respectively pre-tightened at the eight supporting points, then the angles are respectively pulled at the eight supporting points, and the torque applied at the points is large, so the pre-tightening force is tightened by using the converted angles. And finally, rechecking by using a dial indicator a61 and a dial indicator b62 which are respectively arranged on the centering support 65 in the axial direction and the radial direction, namely, rotating the rotating shaft of the dynamometer connecting flange, recording the measured values of the dial indicator in the axial direction and the radial direction, the four radial measured values and the four axial measured values at intervals of 90 degrees, meeting the process requirements, completing centering, and repeating the process operation if the measured values are not met.
The jackscrew device includes the square steel piece and the bolt of screw hole, and the square steel piece welding of screw hole is to the diesel engine base, the jackscrew device respectively two in four azimuths all around at the diesel engine base, the bolt is installed to the screw hole on the square steel piece, the whole stabilizer blade of diesel engine is contacted to the bolt, can rotate the bolt adjustment diesel engine position all around at the centering in-process, and then reach the purpose of diesel engine centering.
In order to accelerate the progress, measurement data can be measured without using a dial indicator a61 and a dial indicator b62, a measuring bolt a63 and a measuring bolt b64 can be connected to the mounting hole of the original centering bracket 65, and when four radial measurement values and four axial measurement values are measured, the clearance between the joint surfaces of the measuring bolt a63 and the measuring bolt b64 and the outer aluminum ring 51 connected with high elasticity is measured by using a feeler, and the precision of the measurement value of the feeler is basically not as high as that of the measurement value of the dial indicator.
As the use condition of the integral support leg 2 is a high-power high-speed diesel engine, after the running-in test is finished, centering data needs to be rechecked, when rechecking is carried out again, the dial indicator a61 and the dial indicator b62 are used for mounting and rechecking four radial measurement values and four axial measurement values, if the measurement values meet the process requirements, the centering data are intact, and if the measurement values do not meet the process requirements, centering operation is repeated.
The measuring method has good reference significance for newly developed high-power machines, and is good in use, popularization and usability under the condition of not using advanced instruments such as a centering instrument and the like.
In the embodiment, measurement is performed at intervals of 90 degrees, and in actual work, measurement can be performed at intervals of 60 degrees to measure 6 groups of data, or the measurement can be arranged according to needs.
The above description is only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily change or replace the technical scope of the present invention. Therefore, the protection scope of the present invention is subject to the protection scope of the claims.
