Abstract
The utility model relates to a novel torque loading calibrating device which belongs to the technology of calibrating test. The calibrating device comprises a cross calibrating rack, hydraulic power assisting cylinders, pull pressure sensors, an upper end shaft, a lower end shaft and a horizontal rack, wherein the center of the cross calibrating rack is fixed on the upper end shaft; the four top ends of the cross calibrating rack are respectively connected with the pull pressure sensors through universal joints; each pull pressure sensor is connected with one hydraulic power assisting cylinder through a bolt; the four hydraulic power assisting cylinders are respectively fixed on the four support bases of the horizontal rack; and a calibrated torque sensor is mounted between the upper and the lower end shafts. In the utility model, by adopting the loading mode, the loading can be uniformly conducted through four power assisting cylinders, the torque sensor can be calibrated without needing to be dismounted from the rotary wing of a helicopter, and therefore, the difficulties that the calibration of the torque sensor with large range is inconvenient, and the torque sensor cannot be calibrated on the spot are solved, and the accurate load of the torque sensor in the operation of the system is reflected.
Description
Technical field
The utility model belongs to the rating test technology, relates to a kind of novel moment of torsion and loads caliberating device.
Background technology
When carrying out lifting airscrew torque sensor rating test, the scaling method of employing is to carry out rating test with being loaded weights on ground by calibration element mostly, then, calibration element is reinstalled returned to original position again.In the lifting airscrew tower, because torque sensor is installed in 15 meters high positions, volume is bigger, and dismounting is difficulty, and the load range owing to torque sensor loads than carrying out full and down again, then needs a large amount of counterweights, loads and demarcates inconvenience.
Summary of the invention
The purpose of this utility model is: a kind of carried convenient that adds is provided, and loading wide ranges, a kind of novel moment of torsion that stated accuracy is high load caliberating device.Technical solution of the present utility model is that caliberating device comprises cross demarcation frame, hydraulic booster tube, pull pressure sensor, upper shaft, lower end axle, level frame; Cross is demarcated the center fixation of frame on upper shaft, four tops that frame demarcated in cross connect pull pressure sensor by universal joint respectively, each pull pressure sensor links to each other with the hydraulic booster tube by bolt, four hydraulic booster tubes are separately fixed on four supporting seats on the level frame, and the torque sensor of being demarcated is installed between upper shaft and the lower end axle.Advantage that the utlity model has and beneficial effect, the utility model adopts by novel load mode, can evenly load by 4 power-assisted tubes, need not torque sensor is pulled down just and can be demarcated it from lifting airscrew, solve the wide range torque sensor and demarcated inconvenient problem, and the difficult point that can't demarcate at the scene torque sensor, the real definite coefficient of reaction torque sensor when system works improved the precision of transducer calibration.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that frame and hydraulic booster tube and pull pressure sensor connection diagram demarcated in the utility model cross.
Embodiment
Below the utility model is described in further details.Caliberating device comprises cross demarcation frame 1, hydraulic booster tube 2, pull pressure sensor 3, upper shaft 5, lower end axle 6, level frame 7; Cross is demarcated the center fixation of frame 1 on upper shaft 5, four tops that frame 1 demarcated in cross connect pull pressure sensor 3 by universal joint 11 respectively, each pull pressure sensor 3 links to each other with hydraulic booster tube 2 by bolt, four hydraulic booster tubes 2 are separately fixed on four supporting seats 14 on the level frame 7, and the torque sensor of being demarcated 4 is installed between upper shaft 5 and the lower end axle 6.
The utility model moment of torsion loads caliberating device and will demarcate on the frame 1 to cross by 4 hydraulic booster tube 2 loading forces, and then, the strong and arm of force has just loaded moment of torsion on upper shaft 5, make the load that has been subjected to moment of torsion by calibration element torque sensor 4; When hydraulic booster tube 2 loads, just can know the load of loading by pull pressure sensor 3, just can calculate the actual torque of the torque sensor that is loaded into 4 again by the load and the arm of force, just can obtain the load of torque sensor by the signal of actual value and torque sensor 4.
When carrying out rating test, lower end axle 6 has bolt 12 to be fixed on down on the transverse plane 13, the lower end of torque sensor 4 is installed in the upper end of lower end axle 6 with bolt 8, the upper end of torque sensor 4 is installed in the bottom of upper shaft 5 by bolt 9, it is fixing that frame 1 is demarcated by bolt 10 and cross in the top of upper shaft 5,4 tops that frame 1 demarcated in cross connect pull pressure sensor 3 by universal joint 11 respectively, pull pressure sensor 3 links to each other with hydraulic booster tube 2 by bolt, hydraulic booster tube 2 is by on the supporting seat 14 on the bolt level frame 7, acting force by hydrostatic control power-assisted tube 2 during use, and the arm of force calculates the size of the load that is loaded.The utility model can effectively improve easy to use at the high pulling torque sensor, has improved loading accuracy, and has realized that the torque sensor of wide range can load at the scene.
