Embodiment
Referring to Fig. 1,2,3, the utility model has fixed plate 7, particularly:Left and right through-hole groove is offered in fixed plate 7 11st, 12 are furnished with left and right fastening bolt 8, and in the left and right ends of fixed plate 7, connection be equipped with left and right telescopic arm, every telescopic arm outside End is provided with the right angle hook 3 to inner side bending, and an axial arranged dial gauge 2 is respectively housed on two right angle hooks 3, and wherein one Dial gauge 10 of the outer end of bar telescopic arm equipped with a radial arrangement.
It is carved with or is printed with to middle mark, left and right telescopic arm and to acceptance of the bid in the centre position of fixed plate 7 in the present embodiment Remember it is equidistant be arranged symmetrically, and be arranged vertically with fixed plate.
The present embodiment middle left and right telescopic arm is by 4 two sections of compositions of fixed arm 6 and lever arm, one end of fixed arm 6 and fixation Plate 7 is fixedly connected, and two groups of clamping screws 5 equipped with front and rear arrangement on fixed arm 6, through-hole groove 13, institute is provided with lever arm 4 The right angle hook 3 stated is the outer end for being located at lever arm 4, and the through-hole groove 13 on lever arm 4 is sleeved on clamping screw 5, is realized flexible Slide and pass through the locking positioning of clamping screw 5.
Operation principle of the present utility model is:Referring to Fig. 1, with the centering job step of water pump and motor shaft installation shaft coupling It is as follows:Half a coupler A1 and half a coupler B9 are set on pump shaft and motor shaft first, then by fixed plate 7 and half Shaft coupling B9 is fixedly connected, while keeps the centering mark of fixed plate and shaft centre line basically identical.Unclamp on telescopic arm Clamping screw 5 lever arm 4 is adjusted to correct position as shown in Figure 1.Start centering, shaft coupling is pressed respectively on end face Vertical direction(Y-direction)And horizontal direction(X-direction)Divide 4 points equally, each point interval 90o, genuine standard measuring sequence is with being located at 0 °, 90 °, 180 °, the radial clearance that measures on 270 ° of four positions be a1, a2, a3, a4;The axial gap that one dial gauge measures For b1 ', b2 ', b3 ', b4 ', the axial gap that another dial gauge for being separated by 180 ° with this measures is b1 ", b2 ", b3 ", b4 ".Four The data of gained are recorded on Fig. 4-7 on individual position.
Four positions obtain data and merged by more than, can obtain a composite record Fig. 8:
b1=(b1′+ b3″)/2
b2=(b2′+ b4″)/2
