Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Shown in composition graphs 1-4, the utility model provides a kind of coupling arrangement 100 for automotive engine test bench, comprise coaxial in the terminal pad body 10 of the turning axle of engine 200, terminal pad body 10 is provided with many groups the first connecting hole 11 near the side of its outer rim, engine is connected to one group in many groups the first connecting hole 11, and terminal pad body 10 is provided with center pit 12, and centrally hole 12 be circumferentially with multiple second connecting hole 13, the shaft coupling 300 of the testboard bay 400 of engine through center pit 12, and is fixed in terminal pad body 10 by the second connecting hole 13.Adopt this technical scheme, according to flywheel 201 diameter of different model engine, and the fixed orifice of distribution on flywheel 201, terminal pad body 10 arranges the first connecting hole 11 that polycomponent does not match with each engine, to improve the versatility of this coupling arrangement, avoid test different model engine and the defect of frequent dismounting that causes, improve work efficiency, the cost simultaneously saved.
In above-mentioned technical scheme, the first end at the second connecting hole 13 place is recessed into towards the side away from shaft coupling and forms the first groove 14, the shaft collar of shaft coupling is embedded in the first groove 14, the setting of the first groove 14 achieves installation location between the two, facilitate the assembling of shaft coupling and brace disk body 10, more direct fitted with terminal pad body 10 by shaft collar after compared with the structure of installing, reduce installation difficulty, reduce operating physical force.
And further, in order to avoid coupling bolt install after and engine flywheel formed and interfere, preferably second end face at the second connecting hole 13 place is recessed into the side away from engine and forms the second groove 15, the coupling bolt being installed on the second connecting hole 13 is placed in the second groove 15, and the first end face is parallel with the second end face, this scheme is that coupling bolt provides and dodges space, makes the coupling bolt after installing be hidden in this and dodges in space, avoid causing interference.
