Embodiment
The principle of concentricity of coupling centering is：The center line centering of two half a couplers must meet two conditions, when
The center of two half a couplers overlaps, that is, makes the cylindrical coincidence of two half a couplers；Second, make the knot of two half a couplers
It is parallel to close end face.Meet two above condition at the same time, then two half a couplers are exactly concentric, otherwise will be to two half a couplers
The machine lower margin gasket of connection is adjusted, and is allowed to meet above-mentioned condition.
According to the principle of concentricity of coupling centering, when low speed toothed coupling concentricity adjusts, two half a couplers
Combination end face parallel adjustment, without specific purpose tool, directly with clearance gauge, slip gauge measure on two half a coupler end faces it is vertical
Distance between 4 points divided, the end face apart from equal i.e. two half a couplers is parallel.Therefore it is same to low speed toothed coupling
The key of heart degree adjustment is the adjustment to the cylindrical concentricity of two half a couplers, and the utility model is devised for adjusting for this
The instrument of the cylindrical concentricity of two half a couplers.
The utility model includes two magnetic stands 1 and two identical centering cards, each centering card by fixed plate 2, hang down
Straight connecting rods 3, horizontal brace rod 4, elevation carrection bar 5 form.
Shown in figure, fixed plate 2 is rectangle steel plate, and fixed plate 2 is disposed vertically, a base of rectangle fixed plate 2
It is horizontally situated, one end of horizontal brace rod 4 is connected to the top center of fixed plate 2, horizontal connection by vertical connecting 3

Circle upper and lower side, had not only reached 1 own level of magnetic stand, but also made mutual level between two magnetic stands 1.
Then, the plate face of the rectangle fixed plate 2 of two centering cards is respectively perpendicular magnetic of the absorption in two magnetic stands 1
On power face, the plate face of two fixed plates 2 is opposite with another 8 direction of half a coupler respectively, while two water of two centering cards
Flushconnection bar 4 is parallel, and two elevation carrection bars 5 are located at the cylindrical upper and lower side of another half a coupler 8.
When two fixed plates 2 are adsorbed main two magnetic stands, in two 2 bottom surface underlay slip gauges 7 of fixed plate, make two
Elevation carrection bar 5 forms certain gap with another 8 outer round surface of half a coupler, to measure.
Then, the gap of two elevation carrection bars 5 and another 8 outer round surface of half a coupler is surveyed using clearance gauge
Amount, if gap is different from the numerical value of the slip gauge 7 of the lower section of fixed plate 2 of the half a coupler 8 of reference side, that is, illustrates two and half shaft couplings
Decentraction, it is necessary to be adjusted, by adjusting gear reducer foundation bolt gasket, realizes two to the center line of device 8 in the horizontal direction
8 center line horizontal direction of half a coupler is concentric.
After the horizontal direction concentricity for having measured two half a couplers 8, the measurement of vertical direction concentricity is carried out.Disk moves band
There is the half a coupler 8 of magnetic stand 1, make magnetic stand 1 in vertical position on half a coupler 8.
The step of two 8 horizontal concentricitys of half a coupler of duplicate measurements, measure two 8 vertical concentric degree of half a coupler
Gap, then gear reducer foundation bolt gasket is adjusted, realize that two cylindrical vertical direction of half a coupler 8 are concentric.
One embodiment production method of the utility model is as follows：
First be processed into the rectangle steel plate of two pieces of 50 × 55 × 10mm with steel plate on grinding machine, rectangle steel plate length,
The scale error of width is controlled in 0.02mm, and two block length square plates are as fixed plate 2.
Again the square steel bar that two root longs are 400mm, section is 10 × 10mm is processed into steel plate on planer.Square steel bar is cut
Into tri- sections of 90mm, 250mm, 35mm, respectively as elevation carrection bar 5, horizontal brace rod 4, vertical connecting 3, then with conduct
The rectangle steel plate of fixed plate 2 is welded into centering card structure.
After welding fabrication, must the artificial reconditioning on grinding plate, control 2 bottom of fixed plate and 5 end face of elevation carrection bar
Make in same plane, control errors are in 0.02mm.
