, technical scheme
In order to solve the problem, the technical solution adopted in the present invention is as follows:
A centralising device for engine and dynamometer machine shaft coupling, comprises location-plate, sleeve, fixture and pointer, and described location-plate is provided with pilot hole; Described sleeve one end is fixed on the center of described location-plate, and the other end is provided with the sleeve pipe be flexibly connected with it; Described sleeve pipe was provided with the vertical through hole in the center of circle, and described fixture is fixed on the other end of sleeve pipe, and the same position place of described fixture and sleeve pipe is provided with onesize through hole, is provided with pointer in through hole.
Further, described pilot hole has four, and equally spaced to be positioned at location-plate circumferentially same.
Further, one end place that described sleeve is connected with sleeve pipe is provided with threaded hole, and described threaded hole is provided with bolt.
Further, the part that described fixture is fixedly connected with sleeve pipe is annular; Through hole annulus is respectively equipped with in the through hole of the upper and lower of described fixture.
Further, the first fixture bolt and the second fixture bolt is respectively equipped with below described fixture and on the outside surface of top through hole.
Further, described pointer is " L " shape, and the part wherein for the outside surface aiming at engine flywheel is parallel to surface level.
, beneficial effect
Compared to prior art, beneficial effect of the present invention is:
1, the centralising device of engine and dynamometer machine shaft coupling solves the low defect of accuracy that manual operation brings,
2, the distance that can control as required between engine and dynamometer machine shaft coupling is shunk by the elongation of sleeve and cannula assembly, less to the distance limit between engine and dynamometer machine shaft coupling, operate convenient.
3, by the distance that fixture steering needle moves up and down, so that be applicable to the centering to the specification engine that varies in size, make the range of application of this device more extensive.
4, this device has the advantage that structure is simple, reasonable in design, be easy to manufacture.
