Because the magnetic of magnetic can weaken in use for some time, influences precision of test result, serviceable life is short, generally needs to change troublesome maintenance after 2 years; Poor in addition position formula torque sensor complex structure, cost height are unfavorable for promoting.
Summary of the invention
The utility model purpose provides a kind of torsion-testing apparatus easy to maintenance, with low cost.
Scheme of the present utility model is: torsion-testing apparatus comprises support, dynamometer machine, torque sensor, mandrel connector, and the testing circuit that is connected with torque sensor, wherein dynamometer machine adopts eddy current dynamometer, its rotation axis is provided with mandrel connector, be connected with tested engine, bright body is provided with central shaft, be set on the support of support, torque sensor is contained between this central shaft and the support, the torque sensor adopts pressure sensor, by shell, foil gauge, depression bar is formed, and shell is fixed on the central shaft of dynamometer machine housing, and depression bar is connected on the support of support.
The utility model has the advantages that: owing to adopted eddy current dynamometer, utilize magnetic field to the load of the electromagnetic resistance of current vortex as tested engine, this dynamometer machine have the life-span long, safeguard simple advantage, made things convenient for the maintenance of whole set equipment.In addition, the cost ratio position formula torque sensor of pressure transducer is low, thereby has reduced cost.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of torque sensor.
Mark among the figure: 1 tested engine, 2 mandrel connectors, 3 bearings, 4 dynamometer machines, 5 supports, 6 torque sensors, 7 supports, 8 testing circuits, 9 blocks; The central shaft of the rotation axis of 4-1 dynamometer machine, 4-2 housing wherein; The shell of 6-1 torque sensor, 6-2 depression bar, 6-3 foil gauge, 6-4 fixed screw.
Embodiment
As shown in Figure 1, torsion-testing apparatus described in the utility model, comprise support 7, dynamometer machine 4, torque sensor 6, mandrel connector 2, and the testing circuit 8 that is connected with torque sensor 6, dynamometer machine 4 adopts eddy current dynamometer, and its rotation axis 4-1 is provided with mandrel connector 2, be connected with tested engine 1, housing is provided with central shaft 4-2, is set in by bearing 3 on the support 5 of support 7, and torque sensor 6 is contained between this central shaft 4-2 and the support 5.
With reference to Fig. 2, torque sensor 6 adopts pressure sensors are made up of shell 6-1, foil gauge 6-3, depression bar 6-2, and shell 6-1 is fixed on the central shaft 4-2 of dynamometer machine housing by fixed screw 6-4, block 9 touchings on depression bar 6-2 and the support are connected on the support.Because depression bar 6-2 limited by block 9, the torsion of the central shaft 4-2 of dynamometer machine housing is converted into pressure and acts on the foil gauge 6-3, and the electric signal size of foil gauge 6-3 output becomes corresponding proportion with torque magnitude, by with the calculating of the arm of force, obtain moment of torsion.Compare with difference position formula torque sensor,, thereby reduced cost because the foil gauge price is low.
During work, the rotation axis 4-1 that tested engine 1 drives dynamometer machine 4 rotates, because eddy current is subjected to the effect in magnetic field, the housing of dynamometer machine 4 is subjected to reacting force, produces the trend of rotating towards rotation axis 4-1 rotation direction, because the restriction of the depression bar 6-2 in the torque sensor 6, this acting force is converted into the pressure to foil gauge 6-3 in the torque sensor, so draw the torque of tested engine 1 indirectly, conversion, demonstration by testing circuit 8 obtain test result.
Owing to adopted eddy current dynamometer, this dynamometer machine to have life-span length, safeguard simple advantage, made things convenient for the maintenance of whole set equipment.
