The invention has simple and compact structure, good assembly manufacturability, symmetrical structure, adjustable and stable generated moment, can be loaded in operation, has small vibration and noise, and can not only be used for a blocking test system of a shaft end loading mode, but also can be used for a blocking test system of a serial-in loading mode.
Description
Technical field
What the present invention relates to is a kind of mechanical hook-up that is used for transmission.
Background technology
The performance test of big type speed reducer is often implemented by the sealing drive experiment system, loader is the critical component in the pilot system, can apply high pulling torque to tested speed reduction unit by torque loader, the actual working state of imitation speed reduction unit, torque loader is to rely on its inner gearing to realize the output of high pulling torque, the less moment that gearing will be imported is amplified back output, makes torque loader produce high pulling torque and is input in the pilot system, and tested speed reduction unit is loaded.The performance of gearing directly affects executing of torque loader and carries size, also just affect the performance of pilot system, if the gearing ratio of gear is big, running steadily, can realize producing when running up big moment, the performance of the performance of torque loader and pilot system is just superior so, and accommodation is just wide.
Though mechanical driving device has multiple, but the gearing that suitable high pulling torque sealing drive experiment system loader is used is considerably less, should produce very high pulling torque, simultaneously again can be at the higher dynamic balance accuracy of maintenance down that runs up, this transmission structures that just requires to use is wanted symmetry, compact.
China is also few in the research of high pulling torque sealing drive experiment system loader aspect gearing, generally all be to concentrate on little torque transmission device aspect, and the external mode of using hydraulic loaded mostly, it is unlimited that this mode can not realize executing year angle, just loads in limited scope.
Summary of the invention
The object of the present invention is to provide and to change the loading moment size, also can change the balanced type transmission device used for torsion loading device of the direction of loading moment easily.
The object of the present invention is achieved like this:
Balanced type transmission device used for torsion loading device of the present invention, it is characterized in that: comprise first order reducing gear and second level reducing gear, first order reducing gear comprises first order reducing gear shell and output steel wheel, second level reducing gear comprises second level reducing gear shell and centre wheel, first order reducing gear shell links to each other with second level reducing gear shell, and the output steel wheel links to each other with centre wheel.
Balanced type transmission device used for torsion loading device of the present invention can also comprise:
1, described first order reducing gear also comprises input shaft and input steel wheel, and an end of input steel wheel links to each other with input shaft, the other end links to each other with the output steel wheel, and first order reducing gear shell is positioned at the outside of input shaft, input steel wheel and output steel wheel.
2, described second level reducing gear also comprises planetary gear, planet axis, planet carrier, output shaft, output shaft sleeve and gear ring, planetary gear and planet axis have three respectively, planetary gear is installed on the planet carrier by planet axis, centre wheel is positioned at the centre of three planetary gears and is meshed with three planetary gears, gear ring is positioned at the outside of three planetary gears and is meshed with three planetary gears, one end of centre wheel links to each other with output shaft, the output shaft sleeve is positioned at the outside of output shaft, and second level reducing gear shell is positioned at the outside of gear ring and links to each other with gear ring.
Advantage of the present invention is: the present invention is simple and compact for structure, and assembly process process is good, structural symmetry, it is adjustable and stable to produce moment, can on-streamly load, and vibration and noise are little, the blocking test system that promptly can be used for the axle head load mode also can be used for sealing in the blocking test system of load mode.

Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～6, the present invention is made up of first order reducing gear input shaft 1, first order reducing gear shell 2, first and second grade reducing gear joint flange 3, second level reducing gear shell 4, output shaft sleeve 5, output shaft 6 etc.First order reducing gear input shaft 1 connects drive motor, first order reducing gear shell 2 links to each other with the axle head of pilot system by the flange of left end, first order reducing gear shell links to each other with second level reducing gear shell 4 by first and second grade reducing gear joint flange 3, second level reducing gear shell 4 links to each other with output shaft sleeve 5 by the flange of end, and output shaft 6 is bearing in output shaft sleeve 5 inside by bearing shell 15 and 16.
Drive motor is imported moment from first order reducing gear input shaft 1, input in the first order reducing gear just wheel 7 is fixed together with shell 2, transmission of torque through input shaft 1 input has just been taken turns on 17 to output, output just wheel 17 links to each other with the centre wheel 15 of second level reducing gear, moment is delivered on the planetary gear 8 through centre wheel 15, planetary gear 8 is delivered to gear ring 10 and 11 to moment simultaneously by the engagement with gear ring 10 and 11, gear ring 10 is connected with housing 4, transmission of torque to second level reducing gear shell 4, second level reducing gear shell 4 links to each other with shaft sleeve 5 again, is linked on the axle head of pilot system.Simultaneously, gear ring 11 by spline housing 12 transmission of torque to output shaft 6, output shaft 6 is linked on another axle head in the pilot system.The less moment of drive motor input through the moment amplification of the first order and second level reducing gear, just produces big moment between second level reducing gear shell 4 and output shaft 6, so just produced high pulling torque between two axle heads in pilot system.
