Description
Technical field
The present invention relates to loading sensing device, be specially the totally-enclosed testing table load sensor of a kind of MW class mechanical output.
Background technology
The totally-enclosed testing table of mechanical output, be applicable to mechanical processing industry and the strength of gear teeth is carried out to MW class gear case, wheel box, speed reduction unit, the test in gear case life-span, energy-saving effect is very outstanding, can do type approval test, delivery test, strength test and fatigue life test.
The core of the totally-enclosed testing table of MW class mechanical output is load sensor.The totally-enclosed testing table of current MW class mechanical output is comprised the main examination speed reduction unit that connected by shaft coupling and accompanies examination speed reduction unit, the input shaft of main examination speed reduction unit is connected by input pickup and gear case, gear case is connected by load sensor and gear case, gear case and output transducer connect, output transducer tries speed reduction unit connection with accompanying, thus forms a mechanical close system.
During work, when main examination speed reduction unit rotates, accompany examination speed reduction unit and then to rotate, motor maintains loading procedure loss by an axle input energy of gear case, and load sensor is connected on an axle of two gear casees, and load sensor loads closed system.
Loader mostly is internal force type loader and external force type loader, and above-mentioned loader all can not to meet within the scope of MW class and freely loads any time or off-load ensure the requirement that stable load and moment and rotating speed are measured in real time after motor starting.
Summary of the invention
In order to solve, existing loader cannot freely load in the present invention, off-load, guarantee stable load and cannot measure the problem of moment and rotating speed in real time, provides a kind of load sensor.
The present invention adopts following technical scheme to realize: load sensor, comprise casing, shared carrier dish is provided with in casing, share input sun wheel shaft carrier dish being provided with shared planet axis and left and right socket, export sun wheel shaft, export in sun wheel shaft and be fixed with output sun gear, share load rows star-wheel planet axis being provided with exporting sun gear and engage, and share sensing planetary gear planet axis being overlapped and has and engage with input sun wheel shaft, sensing planetary gear overcoat has the sensing annular wheel engaged with it, sensing annular wheel is outside equipped with the shaft collar fixing with casing, shaft collar is fixed with torque sensor, load rows star-wheel overcoat has the loading annular wheel engaged with it, load outside annular wheel and be provided with the worm gear engaged with it, worm gear is engaged with worm screw, worm screw is connected with braking motor by speed reduction unit, export around sun wheel shaft and be provided with the speed probe fixing with casing.
Realize loading at any time by braking motor and speed reduction unit, off-load ensure the requirement of stable load; Realize the requirement of extracting torque by torque sensor, realize the requirement of extracting rotating speed by speed probe.
During operation, revolving force is passed to input sun wheel shaft by shaft coupling by the totally-enclosed testing table of MW class mechanical output, and input sun wheel shaft drives sensing planetary gear to carry out rotation and revolution, and shaft collar and sensing annular wheel maintain static dynamic; Sensing planetary gear drives load rows star-wheel rotation and revolution, and then drive the output sun gear that engage with load rows star-wheel and export sun wheel shaft and rotate, the torque sensor on shaft collar extracts the torque and rotational speed of testing table respectively with the axial speed probe of output sun gear; In load sensor operation process, control worm screw by braking motor and speed reduction unit to rotate, and then drive worm gear, loading annular wheel, load rows star-wheel, export sun gear and export sun wheel shaft rotation, realize freely the loading of loader, off-load ensure the requirement of stable load, realize the requirement of measuring moment and rotating speed in real time simultaneously.
Reasonable in design of the present invention is reliable, while the several kilowatts of inorganic loadings to several megawatt can be realized, loading moment size and rotating speed can be measured, loading procedure is without the restriction of stroke, and gap, particularly tested speed reduction unit that in closed system, each connecting link produces are in Multi-stage transmission, backlash at different levels all can be eliminated, thus the smooth loading in one-step installation can be ensured, have and load sensitive, stable, the simple advantage of structure, be particularly suitable for megawatt mechanical output blocking test platform.
