Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use as " upper and lower " normally for direction shown in the drawings or for each parts mutual alignment relationship description word vertically, on vertical or gravity direction.
A kind of engine centralising device as shown in Figures 2 to 5 comprises mid-game, mid-game is connected with transmission output shaft 11, ring flange 21 and the outward extending sleeve part 22 in central coaxial ground from ring flange 21 are comprised to mid-game, be sleeved on transmission output shaft 11 to mid-game by sleeve part 22, between the internal perisporium of sleeve part 22 and the peripheral part of transmission output shaft 11, be formed with the female spline 23 forming spline fitted and male splines 12.
As shown in Figure 3 and Figure 4, sleeve part 22 is formed by centering dish, and female spline 23 is formed on the internal perisporium of sleeve part 22, coordinate with the male splines 12 on the peripheral part of transmission output shaft 11, make can firmly coordinate with transmission output shaft 11 mid-game, to realize the right alignment to mid-game and transmission output shaft 11, thus improve the accuracy of alignment of engine centralising device.
Especially, engine centralising device also comprises laser alignment instrument, this laser alignment instrument comprises controller, generating laser and laser pickoff, generating laser is arranged on in mid-game and dynamometer machine output shaft, laser pickoff be arranged on to mid-game and dynamometer machine output shaft another on, controller communicates with laser pickoff with generating laser respectively.Engine centralising device of the present utility model, by laser alignment instrument centering, substantially increases accuracy of alignment and the efficiency of engine centralising device.
Be applied in engine centering test macro to mid-game, engine centering test macro comprises engine to be measured, the variator be connected with engine to be measured and dynamometer machine, and engine to be measured passes through adjustable support installing on ground black iron.
When engine centering test macro centering, to be sleeved on transmission output shaft 11 by spline fitted to the sleeve part 22 of mid-game, again the generating laser of laser alignment instrument is arranged on in mid-game and dynamometer machine output shaft, laser pickoff be arranged on to mid-game and dynamometer machine output shaft another on, by the transmitting and receiving of laser, data are reacted on controller, operator regulates the support supporting engine to be measured to regulate the position of engine to be measured, until centering by the data of controller.The Middle Phase ratio of laser alignment instrument and dial gauge, operator regulates support by the change observing the data on controller simultaneously, to find centering position accurately, improves accuracy of alignment and the efficiency of engine centralising device.
In order to process and coordinate conveniently, especially, female spline 23 is along on the internal perisporium being disposed axially in sleeve part 22 of sleeve part 22.In the present embodiment, female spline 23 is arranged on the internal perisporium of sleeve part 22, male splines 12 is formed on the peripheral part of transmission output shaft 11, but the utility model is not limited thereto, the position of female spline 23 and male splines 12 is interchangeable, as long as and the layout of female spline 23 and male splines 12 can firmly coordinate mutually.
The axial length of male splines 12 is not necessarily equal with the axial length of female spline 23, as long as can play the fixing effect to mid-game, therefore especially, the axial length of male splines 12 is not less than 18mm.
Especially, the diameter of ring flange 21 is 4-6 times of the diameter of transmission output shaft 11.Owing to inserting on transmission output shaft to mid-game, realize arranging mid-game and transmission output shaft concentric, not easily measure because the diameter of transmission output shaft is relatively little and observes again, therefore the utility model is by amplifying the departure of dynamometer machine output shaft and transmission output shaft to the diameter of mid-game, make the precision of centering higher, more easily regulate the position of engine, also improve the efficiency of centering simultaneously.
