Abstract
The utility model relates to a mechanical loader which solves the problem that the existing loader can not carry out free loading and unloading and can not ensure stable load. The mechanical loader comprises a box body. A common star frame plate is arranged in the box body. A common planetary shaft, an input sun wheel shaft and an output sun wheel shaft are arranged on the common star frame plate, wherein the input sun wheel shaft and the output sun wheel shaft are in sleeve joint left and right. The output sun wheel shaft is fixed with an output sun wheel. A loading planetary wheel is arranged on the common planetary shaft, and the common planetary shaft is sleeved with a sensing planetary wheel. The outside of the sensing planetary wheel is sleeved with a sensing inner gear. A fixation plate is arranged outside the sensing inner gear. The outside of the loading planetary wheel is sleeved with a loading inner gear. A worm wheel is arranged outside the loading inner gear. The worm wheel is meshed with a worm. The worm is connected with a brake motor. According to the utility model, stepless loading is realized, and the mechanical loader has the advantages of sensitive loading and unloading, stability and simple structure.
Description
Technical field
The utility model relates to charger, is specially the totally-enclosed testing table machine loader of a kind of MW class mechanical output.
Background technology
The totally-enclosed testing table of mechanical output, be applicable to mechanical processing industry MW class gear case, wheel box, speed reduction unit are carried out the strength of gear teeth, the test in gear case life-span, energy-saving effect are 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 machine loader.The totally-enclosed testing table of MW class mechanical output comprises the main examination speed reduction unit that connects by shaft coupling and accompanies the examination speed reduction unit at present, the input shaft of main examination speed reduction unit connects by input pickup and gear case, gear case connects by machine loader and gear case, gear case and output transducer connect, output transducer tries the speed reduction unit connection with accompanying, thereby forms a mechanical close system.
During work, when main examination speed reduction unit rotates, accompany the examination speed reduction unit and then to rotate, motor is by an axle input energy of gear case, keep the loss of system's operation process, machine loader is connected on the axle of two gear casees, and machine loader loads closed system.
Loader mostly is internal force type loader and external force type loader, and above-mentioned loader all can not satisfy behind motor starting in the MW class scope and freely to load off-load and to guarantee the requirement that load is stable any time.
Summary of the invention
The utility model can't free loading, off-load and guarantee the stable problem of load in order to solve existing loader, and a kind of machine loader is provided.
The utility model is to adopt following technical scheme to realize: machine loader, comprise casing, be provided with in the casing and share star frame dish, share be provided with on the star frame dish share planet axis and about the input sun wheel shaft of socket, the output sun wheel shaft, be fixed with the output sun gear on the output sun wheel shaft, share and be provided with on the planet axis and the load rows star-wheel of exporting the sun gear engagement, and cover has the sensing planetary gear that meshes with the input sun wheel shaft on the shared planet axis, sensing planetary gear overcoat has the sensing annular wheel with its engagement, the sensing annular wheel is outside equipped with the shaft collar fixing with casing, load rows star-wheel overcoat has the loading annular wheel with its engagement, the loading annular wheel is provided with the worm gear with its engagement outward, be engaged with worm screw on the worm gear, be connected with braking motor by speed reduction unit on the worm screw.
During operation, the totally-enclosed testing table of MW class mechanical output passes to the input sun wheel shaft with revolving force by shaft coupling, and the input sun wheel shaft drives the sensing planetary gear and carries out rotation and revolution, and shaft collar and sensing annular wheel maintain static moving; The sensing planetary gear drives load rows star-wheel rotation and revolution, and then the output sun gear of drive and the engagement of load rows star-wheel and the rotation of output sun wheel shaft; In the machine loader operation process, rotate by braking motor and speed reduction unit control worm screw, and then drive worm gear, loading annular wheel, load rows star-wheel, output sun gear and the rotation of output sun wheel shaft, realize free loading, the off-load of loader and guarantee the requirement that load is stable.
The utility model reasonable in design is reliable, can realize several kilowatts to the stepless loading of several megawatts, add the restriction that the off-load process is not subjected to stroke, the gap that each connecting link produces in closed system, particularly tested speed reduction unit is in the Multi-stage transmission, and backlash at different levels all can be eliminated, thereby can guarantee to add smoothly off-load in the one-step installation, have advantages of the off-load of adding sensitivity, stable, simple in structure, be particularly suitable for megawatt mechanical output blocking test platform.
