Abstract
The utility model discloses a flexible coupling, comprising a load crankshaft, a stepped spline coupling sleeve connected with the load crankshaft and an output spline shaft of an engine and a stopping screw. The load crankshaft is a stepped shaft; the thin end shaft of the stepped shaft is axially provided with a slot for the slide of the stopping screw; the stopping screw radially passes though one end of the coupling sleeve and extends into the slot of the load crankshaft; the thin end of the load crankshaft is sheathed with a compressed spring which is arranged between the step of the load crankshaft and the step of the spline coupling sleeve. The flexible coupling can capture automatically and sheath into the spline shaft without manual adjustment; the automatic butt joint of a running-in loading machine and an engine is realized, and the work efficiency is greatly enhanced. The flexible coupling can be widely used for the occasion of running-in and load test of the engine.
Description
Technical field the utility model relates to a kind of hitch bar, relates to a kind of flexible coupling that is used to connect motorcycle engine output shaft and break-in loading arbor particularly.
After background technique motorcycle engine assembling is finished, need carry out break-in and load test it, this test for each performance parameter of grasping motor, guarantee its quality of product one procedure that is absolutely necessary.In test process, the main shaft that break-in need be added carrier aircraft docks with the output shaft spline of motor, and this butt joint is added by break-in normally that the spline coupling band socket engine output shaft spline of carrier aircraft realizes.Existing coupling is because spline coupling band and break-in add the main shaft of carrier aircraft is bolted to connection, the main shaft that spline coupling band and break-in add carrier aircraft can not relatively move, this rigid bind mode is just usually docking not, the defective that has butt joint difficulty, inconvenient operation, need repeatedly the rotation of spline coupling band to be aligned by the people, sometimes also can occur having had a strong impact on the test process of motor because butt joint is not just causing spline coupling band and the dead phenomenon of engine output shaft spline compressing.
Summary of the invention is at the prior art above shortcomings, and the purpose of this utility model just provides a kind of flexible coupling that can realize that automatic butt puts in place.
The technical solution of the utility model is achieved in that a kind of flexible coupling, comprises the loading arbor, and with the ladder spline coupling band that is connected loading arbor and motor output spline, it also comprises stopping screw in addition, and the loading arbor is a multidiameter shaft; The thin end of described multidiameter shaft axially has the groove that slides for stopping screw, and stopping screw radially passes coupling band one end and stretches in the groove that loads arbor; Load on the thin end of arbor and be set with compressed spring, spring is between the ladder of ladder that loads arbor and spline coupling band.
The further feature of the utility model is that described spring is loading between arbor ladder and the stopping screw.
Adopt the break-in of technique scheme to add the carrier aircraft coupling, be set with holddown spring owing to load the thin end of arbor, even not just butt joint do not occur, it is flexible vertically flexible that the spline coupling band also can load arbor relatively, it is dead to be unlikely to compressing, and since the elastic force of the cooperation holddown spring of stopping screw can be guaranteed.When the main shaft that adds carrier aircraft when break-in rotated at a slow speed, the spline coupling band can be found accurately automatically under the effect of spring force and is inserted in splined shaft, need not manual tune, has realized that break-in adds the automatic butt of carrier aircraft and motor, has improved working efficiency greatly.Be particularly useful for the break-in and loading test occasion of motor.
Description of drawings is described in further detail the utility model below in conjunction with accompanying drawing:
Fig. 1 is the coupling butt joint schematic representation of prior art.
Fig. 2 is a coupling butt joint schematic representation of the present utility model.
The coupling of embodiment prior art as shown in Figure 1.As can be seen from Figure 1, the coupling of prior art loads arbor 1 by connecting, connection loads arbor 1 and forms with the spline coupling band 4 and the connecting bolt 7 of motor output spline 5, load between arbor 1 and the spline coupling band 4 fixing by connecting bolt 7, loading arbor 1 and spline coupling band 4 can not relatively move, motor output spline 5 can only with 4 rigid connections of spline coupling band.The coupling of this rigid connection uses very inconvenience, and inefficiency has had a strong impact on the test process of motor.
The utility model coupling one mode of execution as shown in Figure 2.As can be seen from Figure 2, the utility model comprises loading arbor 1, and with the spline coupling band 4 that is connected loading arbor 1 and motor output spline 5, it also comprises stopping screw 3, and loading arbor 1 is multidiameter shaft; The thin end of described multidiameter shaft axially has the groove 6 that slides for stopping screw 3, and stopping screw 3 radially passes coupling band 4 one ends and stretches in the groove 6 that loads arbor 1; Load on the arbor 1 thin end and be set with compressed spring 2, in the space of spring 2 between the ladder of ladder that loads arbor 1 and spline coupling band 4.
Another mode of execution of the present utility model, omit accompanying drawing: main body is with above-mentioned the same, and loading arbor 1 is the one-level multidiameter shaft, and its diameter at smaller end footpath is identical with motor output spline 5 diameters, and its middle part has a groove 6 that supplies stopping screw 3 to slide; Spring 2 is between the ladder and stopping screw 3 that load arbor 1.
The utility model is under original state, and spring 2 is compressed, and stopping screw 3 is because the effect of spring force is positioned at groove 6 away from loading arbor 1 butt end one side.Spline coupling band 4 moves along loading arbor 1 and restricted jointly by two factors: the one, and the length of groove 6; Another is the elastic range of spring 2.In the process of butt joint, spline coupling band 4 can constantly move in the distance range of these two factor decisions.
The utility model is not limited to above-mentioned mode of execution; for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention, can also make some modification or improvement, everyly utilize spring and stopping screw to carry out flexible docking all to drop within the protection domain of the present utility model.
