Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
It is a kind of using the whole diesel engine of stabilizer blade and the centering method of dynamometer as shown in attached drawing 1~4, by diesel engine 1,
Whole stabilizer blade 2, diesel engine bottom 3, dynamometer 4, connection high-elastic 5, centering bracket 6 etc. form.
The centering rack 6 includes centering bracket 65, measurement bolt a63 and measurement bolt b64；Wherein, pair
The end of the vertical long side of middle bracket 65 is arranged on dynamometer 4 and its horizontal short is arranged towards diesel engine 1；Centering bracket 65
Vertical long side on be provided with and connect high-elastic 5 axially contact measurement bolt a63, for measuring axially aligning for diesel engine 1
Error；It is provided in the horizontal short of centering bracket 65 and connect the high-elastic 5 measurement bolt b64 radially contacted with, for measuring bavin
The radially aligned error of oil machine 1.
Specific work step is: before the progress that works in all pairs, dynamometer 4 and diesel oil machine base 3 are according to design
Size requires earlier pre-pair to finish.
The diesel engine 1 is fixedly connected before installation is in whole stabilizer blade 2, being equipped with whole stabilizer blade 2
Diesel engine 1, which is placed into, have been fixed on intact diesel oil machine base 3, the external aluminium circle 51 of connection high-elastic 5 and the rubber that connect high-elastic 5
Gear ring, which does not depart from, to be separated, and the external aluminium circle 51 of connection high-elastic 5 is fixedly connected with 1 flywheel of diesel engine, makes to connect high-elastic 5
External aluminium circle 51 and 5 flywheel of diesel engine are an entirety, the connection elastomer connecting flange 52 and measurement of power of connection high-elastic 5
The connecting flange 41 of device 4 is fixedly connected, and is made to connect high-elastic 5 and is combined into an entirety with 4 groups of dynamometer.
Centering bracket 65 is fixed on the connecting flange 41 of dynamometer 4, on to middle bracket 65 axially and radially direction
Dial gauge a61 dial gauge b62 is installed respectively, 4 connecting flange shaft of dynamometer is rotated, records primary axial direction and diameter at interval of 90 °
The value of dial gauge a61 dial gauge b62 on direction, obtains radial four measured values, and axial four measured values are remembered according to radial
The value of record is using the micro mobile diesel engine 1 of jackscrew device on diesel oil machine base 3, according to the axial value recorded in dynamometer 4
Appropriate gasket is padded in bottom, because being connect using whole stabilizer blade 2 with diesel engine 1 is stability in order to increase diesel engine 1, no
It is recommended that adding gasket at whole stabilizer blade 2 and pedestal 3 to carry out in, it is therefore intended that the radial and axial measured value of four direction
It is consistent as far as possible.It is stationary state since diesel engine 1 is in, so guaranteeing diesel oil in the up and down direction of radial direction
Machine 1 is 0.2-0.3mm higher than dynamometer 4, it is therefore intended that after the fixed diesel engine 1 of fastening bolt a and fastening bolt b, diesel engine 1
It can decline.
After the four direction value of measurement meets technique required value, passed through using fastening bolt a7, fastening bolt b8 whole
The unthreaded hole 21 of stabilizer blade 2, torque spanner tightens fastening bolt a7, tightly fixing bolt b8 respectively and pre-tightens diesel engine 1, then by pulling angle
Degree tightens fastening bolt a7, fastening bolt b8 respectively, after pulling angle process, checks the pre- of another bolt and next pulls angle again
Degree when connecting supporting point at the eight of fastening diesel engine 1, will operate in every place's supporting point and supporting point pre-tightens respectively at eight,
Then supporting point pulls angle respectively at eight again, since place application torque is larger, so next in pretightning force use conversion
Angle afterwards is tightened.Finally using the dial gauge a61 and dial gauge b62 installed respectively on centering bracket 65 axially and radially direction
Check, i.e. rotation dynamometer connecting flange shaft, at interval of the measurement of dial gauge on the primary axially and radially direction of 90 ° of records
Value, radial four measured values, axial four measured values meet technique requirement, and centering is completed, if not satisfied, repeating the above process
Operation.
Jackscrew device includes the square steel block and bolt of threaded hole, in the square steel block welding to diesel oil machine base of threaded hole, institute
For the jackscrew device stated each two on diesel oil machine base all around four orientation, the threaded hole on square steel block is equipped with bolt,
Threaded bolt contacts can adjust the position of diesel engine all around to diesel engine entirety stabilizer blade during in rotating bolt, into
And achieve the purpose that diesel engine centering.
Data can be measured without using dial gauge a61 and dial gauge b62 to accelerate progress, it can be original to right
Connection measurement bolt a63 and measurement bolt b64 at the mounting hole of middle bracket 65, in radial four measured values of measurement and axially four
When measured value, using clearance gauge measure measurement bolt a63 and measure bolt b64 with connect high-elastic 51 faying face of external aluminium circle
Gap, it is high not as good as dial gauge measured value precision using clearance gauge measured value in principle.
Since 2 use condition of entirety stabilizer blade is Large-power High-Speed diesel engine, after running-in test, check pair is needed
Middle data when checking again, carry out radial four measured values of installation check and axial four using dial gauge a61 and dial gauge b62
A measured value, if measured value meets technique requirement, centering data are intact, if not satisfied, repeating centering operation.
The measurement method is for newly developing high-power machine with good reference, advanced not by centering instrument etc.
In the case where instrument, application and popularizations usability is good.
It uses in the present embodiment and is measured every 90 °, in actual operation, one can also be carried out using every 60 °
Secondary measurement surveys 6 groups of data, also can according to need and arrange by oneself.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can change or replacement easily, belong to this hair
Within bright protection scope.Therefore it is subject to the protection scope in claims described in protection scope of the present invention.
