Embodiment
Present embodiment is used for the explanation to the requirement of this paper utility model right, and the protection domain that the utility model requires is not limited to following description scheme.
As shown in Figure 1, establish central shaft 101 on the back-up block 100, back-up block 100 is an one-piece parts with central shaft 101.Central shaft 101 is by bearing 300 and rotation 200 sheathed connections of test rod.The lower surface 201 of rotation test rod 200 does not contact with back-up block upper surface 102
As shown in Figure 1, 2, rotation test rod 200 can be a straight-bar, straight-bar that is complementary with the flywheel shell of engine intracavity diameter or the straight-bar that is complementary with flywheel shell of engine inner chamber radius.Also can be that described rotation test rod is fan-shaped bar, the radius of fan-shaped bar be complementary with flywheel shell of engine inner chamber radius.Or the rotation test rod be biparting shape bar, the diameter of biparting shape bar and flywheel shell of engine intracavity diameter are complementary.Described here be complementary be meant corresponding on the size, promptly be that the length of rotation test rod is identical with the engine flywheel diameter or the radius of flywheel shell of engine connection.
Have two detection faces on the rotation test rod 200, first detection faces is positioned at rotation test rod end, and it is plane or arc surface.Because rotation test rod 200 adopts the straight-bar that is complementary with the flywheel shell of engine intracavity diameter among the present embodiment figure, therefore, it has two first detection faces 207.
Second detection faces is positioned at the lower surface of rotation test rod 200, include in the outer contour of the axial cross section of second detection faces and the flywheel shell of engine inner chamber bottom surface axial cross section outer contour part that is complementary, the outer contour ABCDEFGHIK section flywheel shell of engine inner chamber bottom surface axial cross section outer contour of the axial cross section of second detection faces is complementary among the present embodiment figure, the shape that being complementary here refers to the engine flywheel end face that connects at the shape of same shaft section inside and outside contour line ABCDEFG section and flywheel shell of engine is identical, and is same or similar with same shaft section intrinsic motivation bell housing inner chamber bottom shape.Because rotation test rod 200 adopts the straight-bar that is complementary with the flywheel shell of engine intracavity diameter among the present embodiment figure, therefore, it has two second detection faces 206.
As shown in Figure 1, 2, 3, offer connecting hole 202 on the rotation test rod 200, connecting hole 202 is provided with bearing second limited step 203.
