Description
Technical field
The utility model is related to machinery loading device field, more particularly to a kind of torsion for being used to close power gear test stand
Load maintainer.
Background technology
Gear durability test requires load maintainer working stability, reliable, and easy to adjust, process of the test can be to greatest extent
Save energy resource consumption.At present, loading device mainly have mechanical load, hydraulic loaded, electrical power closing loading three kinds of forms, but by
It need to manually adjust, loading is extremely inconvenient, and easily unload in tradition machinery loading, load is unstable；And hydraulic loaded, electrical power
Closing loading belongs to external force loading, is required to maintain power to input always, and hydraulic loaded requires high to hydraulic system, and energy disappears
Consumption is too big, and electrical power closing Loading Control System is complicated, and equipment cost is high；And worm and gear loading belongs to the loading of internal force type,
And there is self-locking performance when the lead angle of worm screw is less than the equivalent friction angle of engagement between cog, Worm Wheel System has big transmission
Than large carrying capacity, stable drive is often used in transmitting the motion between two alternating axis and power, therefore propose a kind of utilize
Worm and gear closes the torsion load maintainer of power gear test stand being used for of loading.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of torsion loading machine for being used to close power gear test stand
Structure, the torsion load maintainer can effectively solve the problem that the loading of existing machinery loading device is unstable, adjustment is inconvenient, and loading
The problem of easily unloading afterwards.
The technical scheme that the utility model is used is：A kind of torsion load maintainer for being used to close power gear test stand,
Left end cap and right end cap, input shaft and output shaft including support frame, positioned at support frame both sides, input shaft are rotatably mounted on branch
On the left end cap of support, output shaft is fixedly connected with right end cap；Interval is provided with the biography of a pair of diameter parallels on support frame as described above
Dynamic worm screw and the worm gear being meshed with two geared worms, each equal rotating dress in geared worm two ends are assigned on support frame, and
Two geared worms are respectively provided with power intake, described worm gear and offer internal spline, and worm gear passes through internal spline and input shaft
End fix be connected.
It is described as a kind of further optimization for the torsion load maintainer for being used to close power gear test stand of the utility model
Geared worm two ends be provided with and be used for the inserting section that geared worm is rotated, offer dress for geared worm inserting in inserting section
Distribution, geared worm rotates inserting in pilot hole by bearing.
It is described as a kind of further optimization for the torsion load maintainer for being used to close power gear test stand of the utility model
Geared worm power intake have be used for couple power input load segment, load segment be provided with keyway, geared worm lead to
Cross keyway connection power input.
It is described as a kind of further optimization for the torsion load maintainer for being used to close power gear test stand of the utility model
Worm gear on the internal spline that opens up be coaxially set with worm gear.
Compared with prior art, the utility model, which at least has, has the advantage that and beneficial effect：
Rotated while the utility model is by a pair of geared worms, drive the rotation of worm gear, worm gear band driven input shaft turns
Dynamic, because of input shaft and the rotation installation of support frame left end cap, output shaft is fixedly connected with the right end cap of support frame, so input shaft turns
Support frame is motionless when dynamic, and output shaft is motionless, and input shaft keeps stable after rotating by the self-locking performance of twin worm, that is to say, that input
Axle and one angle of output shaft relative torsion, so as to realize the loading of test torque.Worm and gear loading belongs to the loading of internal force type,
Worm Wheel System has gearratio big, and stable movement bears the big advantage of load, can realize that stable moment of torsion is loaded, and by
In the self-locking performance of worm screw, it can guarantee that added load does not unload or unloaded very little.The torsion load maintainer, can effectively solve the problem that existing
There is machinery loading device loading unstable, adjustment inconvenience, and after loading the problem of easy unloading.

Embodiment
To become apparent content of the present utility model, below in conjunction with specific embodiment, the utility model is carried out detailed
Thin description.
Be used to closing the torsion load maintainer of power gear test stand as illustrated, a kind of, including support frame 1, positioned at support
Left end cap 5 and right end cap 6, the input shaft 4 and output shaft 7 of the both sides of frame 1, input shaft 4 are rotatably mounted on the left end cap of support frame 1
On 5, output shaft 7 is fixedly connected with right end cap 6；On support frame as described above 1 interval be provided with the geared worm 2 of a pair of diameter parallels with
And the worm gear 3 being meshed with two geared worms 2, the equal rotating dress in each two ends of geared worm 2 is assigned on support frame 1, and two
Geared worm 2 is respectively provided with power intake, described worm gear 3 and offers internal spline, and worm gear 3 passes through internal spline and input shaft 4
End fix be connected.
In order that the utility model has more preferable using effect, the described two ends of geared worm 2, which are provided with, to be used to be driven snail
