Detailed description of the invention
As shown in Figure 1 and Figure 2: a kind of rotor coupling looks for middle instrument, comprising first looks for middle external member 10, second to look for middle external member 11 and dish to ship and resell on another market 9;
Described first looks for middle external member 10 to comprise looks for axis 3, expansion sleeve 2, right angle dial framework plate 5; Described right section of looking for axis 3 is taper, and it and expansion sleeve 2 endoporus form the axis of cone/taper hole and coordinate, and look for axis 3 two ends to have screw thread, right-hand member screw thread are furnished with swelling nut 1; Right angle dial framework plate 5 is fastened on by left end clamp nut 7 to be looked on axis 3;
Described second looks for middle external member 11 to comprise looks for axis 3, expansion sleeve 2, straight plate dial framework plate 8; Described right section of looking for axis 3 is taper, and it and expansion sleeve 2 endoporus form the axis of cone/taper hole and coordinate, and look for axis 3 two ends to have screw thread, right-hand member screw thread are furnished with swelling nut 1; Straight plate dial framework plate 8 is fastened on and looks on axis 3 by left end clamp nut 7.
Above-mentioned two cover look in middle external member, described in look for axis 3 left sections of diameters less than right section of axis of cone diameter, itself and shaft coupling A screw N keep gap.Described expansion sleeve 2 is the guide of second two halves upper composition, increases guide expansion scope when being convenient to swelling.Described right angle dial framework plate 5 is divided into orthogonal two sections, is all provided with dial gauge 4.Described straight plate dial framework plate 8 is a straight section, is also provided with dial gauge 4 above.Described dish 9 diameters of shipping and reselling on another market are more smaller than shaft coupling screw, and its one end cover has rotating disk rope 12.
The utility model using method: look for RC 2 shaft couplings for needs see Fig. 3 and Fig. 4, Fig. 5, A and B.First first, second being looked for middle external member 10,11 to put into shaft coupling B(also can be A) two symmetrical bolt hole M, then twist swelling nut 1 at shaft coupling B end face D to draw and look for axis 3, make to look for axis 3 swelling together with expansion sleeve 2 in the screw M of shaft coupling B, then right angle dial framework plate 5, straight plate dial framework plate 8 to be fastened on clamp nut 7 and respectively to suffer from one's own actions the other end on axis 3.Then dial gauge 4 is respectively charged into orthogonal two sections of right angle dial framework plate 5, in the installing hole that measurement shaft coupling A cylindrical E beats and end face C beats; Dial gauge 4 is loaded straight plate dial framework plate 8, in the installing hole that measurement shaft coupling A end face C beats simultaneously; Dial gauge 4 is made to measure syringe needle contact measurement face and pre-2mm, then with holding screw 6, dial gauge 4 is fixed on right angle dial framework plate 5, straight plate dial framework plate 8, rotating dial plate again makes each dial gauge 4 initial reading be 0, and dish is shipped and resell on another market in 9 loading two shaft coupling screws, and dish ship and resell on another market 9 one end cover on dish turn rope 12.
Look for middle instrument installation like this, just can turn rope 12 by dish and read and record each dial gauge data value along the dish dynamic direction dynamic rotor coupling of X dish, then calculate the equation of the ecentre between shaft coupling A, B, for follow-up adjustment work provides reliable foundation.
The utility model instrument looks for middle precision high, and look for middle cylindrical precision can reach Φ 0.03mm, end face precision can reach 0.02mm.Middle work is looked at center when being applied to mechanical equipment installation before rotation axis system flange coupling, is particularly suitable for the shaft coupling that diameter is greater than Ф 200mm.
