Abstract
The utility model relates to a mechanical loader which solves the problems that the existing loader cannot meet the requirements of freely loading or deloading at any time in a megawatt-level range and ensuring stable load after a motor is started. The mechanical loader comprises a speed reducer which is provided with a first output shaft and a second output shaft, wherein the first output shaft and the second output shaft are respectively connected with a shaft and a gear of a loading gear box, a motor is arranged on an input shaft of the speed reducer, the input shaft is also connected with a shaft of the motor, and a power supply system and a power-off brake are arranged on the motor. The mechanical loader has reasonable and reliable structural design, can realize inorganic loading of multi kilowatts and has no travel limitation in a loading process, the clearance generated during each connected link in an enclosed system, especially the tested speed reducer is in multi-stage transmission, the clearance at the gear side of each stage can be eliminated so that the smooth loading in one-time installation can be ensured, and the mechanical loader has the advantages of sensitive and stable loading and the like and is especially suitable for a high-power mechanical enclosed test table.
Description
Technical field
The utility model relates to loader, is specially a kind of mechanical load device.
Background technology
The totally-enclosed testing table of MW class mechanical output, be applicable to that mechanical processing industry carries out the strength of gear teeth to MW class gear case, wheel box, speed reduction unit, 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.Yet the core of the totally-enclosed testing table of MW class mechanical output is the mechanical load device.The totally-enclosed testing table of MW class mechanical output comprises the tested speed reduction unit 4 that connects by shaft coupling 5 and accompanies examination speed reduction unit 6 at present, the input shaft of tested speed reduction unit 4 connects by input pickup 3 and loaded teeth roller box 2, loaded teeth roller box 2 connects by transmission shaft 8 and gear case 9, gear case 9 and output transducer 7 connect, output transducer 7 tries speed reduction unit 6 connections with accompanying, thereby forms a mechanical close system.During work,, tested speed reduction unit 4 accompany examination speed reduction unit 6 and then to rotate when rotating.Motor 1 is kept the loading procedure loss by an axle intake of loaded teeth roller box 2, and loader 10 is connected on another root axle of loaded teeth roller box, and 10 pairs of closed systems of loader load.Loader mostly is internal force type loader and external force type loader, and above-mentioned loader all can not satisfy in the MW class scope any time free loading or off-load and guarantee the requirement that load is stable behind motor starting.
Summary of the invention
The utility model provides a kind of mechanical load device in order to solve existing loader all can not satisfy in the MW class scope free loading or off-load any time and guarantee the load stability requirement behind motor starting problem.
The utility model is to adopt following technical scheme to realize: the mechanical load device, comprise speed reduction unit, speed reduction unit is provided with first output shaft and second output shaft that connects with the axle and the gear of loaded teeth roller box respectively, input shaft of speed reducer is provided with motor and connects with the output shaft of motor, and motor is provided with electric power system and electricity loss brake.Electric power system power supply when the mechanical load device loads, motor just changes, first output shaft, second output shaft that drive speed reduction unit are done and are relatively rotated, thereby make the axle and the gear of loaded teeth roller box relatively rotate loading, after meeting the requirements of load, electric power system outage, the electricity loss brake of mechanical load device keep the load of loading constant; Electric power system power supply when the needs off-load, the motor counter-rotating, first output shaft, second output shaft make the axle and the gear of loaded teeth roller box relatively rotate off-load in the other direction, after meeting the requirements of load, the electric power system outage, the electricity loss brake of mechanical load device keeps the load that loads constant, realizes finally that the mechanical load device can load at any time or off-load and guarantee the requirement that load is stable.
The utility model reasonable in design is reliable, can realize several kilowatts inorganic loading, loading procedure does not have the restriction of stroke, the gap that each connecting link produces in closed system, particularly tested speed reduction unit is in the multistage transmission, and backlash at different levels all can be eliminated, thereby can guarantee the smooth loading in the one-step installation, have and load advantages such as sensitive, stable, be particularly suitable for high-power machinery blocking test platform.
