Frame 3 is provided with some water inlet pipe 15, outlet pipes 16 to be connected with cooling line 6, the neighbouring transmission of water inlet pipe 15, outlet pipe 16
The axle center of axle 5, water inlet pipe 15, outlet pipe 16 are all hard material.
It is in laterally uniform annular groove 17 that the periphery of rotor 7, which is provided with some, in annular groove 17, rotor 7 and stator 8
Between gap in all put have magnetic.
The water inlet pipe 15, outlet pipe 16 are located at the position that same axle center is in power transmission shaft 5.
Described one end of power transmission shaft 5 is provided with a grating disc 18；It is provided with the sensing frame 3 corresponding with the position of grating disc 18
Photoelectric sensor 19.
The both sides of torque arm 13 are provided with screw that is mutually symmetrical and being connected with sensing hole 14, and screwhole position passes with pressure
The upper end position of sensor 11 is corresponding；Set screw is bolted with the screw.
Application method of the present utility model is as follows：
When needing to test the moment of torsion of engine, the rotating shaft of engine is connected with power transmission shaft 5 by shaft coupling,
Engine is then turned on, the now rotating shaft of engine will rotate, and drive power transmission shaft 5 to rotate simultaneously, due to power transmission shaft 5
Rotor 7 is arranged with outside, rotor 7 can rotate with, and when the magnet exciting coil in brake applies certain electric current, stator 8 can be given
Rotor 7 applies a resistance, and its reaction force can make stator 8 certain swing occur, so as to drive the torsion on brake 4
Power bar 13 is swung, and now pressure sensor can be touched constantly with the inwall both sides of sensing hole 14 on torque arm, to pressure sensor
Certain pressure is produced, pressure sensor can export the electric signal of certain amplitude, and this electrical signal amplitude is proportional to pressure sensor
The pressure being subject to, because the distance that torque arm touches in the off-axis heart in the position of pressure sensor is certain value, that is to say, that the arm of force
For certain value, so the pressure that pressure sensor is subject to is proportional to the moment of torsion applied to engine, that is to say, that pressure sensor
The electrical signal amplitude of output is proportional to the moment of torsion applied to engine, so as to the moment of torsion of accurately test engine, pressure
The touching each time of sensor and sensing hole can all form information and be collected by pressure sensor 11, and final pressure sensor 11 then can
Output signal, actual data are formed, allow staff to can be apparent that the moment of torsion of tested engine, thus may be used
Know, after pressure sensor 11 is arranged in the mounting groove 9 of sensing frame 3, reduces the presence of installs case, production can be reduced
Cost, production efficiency is improved, and with the removal of installs case, can effectively avoided because installs case shakes the feelings of generation noise
Condition.
Although water inlet pipe 15 of the present utility model, outlet pipe 16 are using hard material, due to water inlet pipe 15, outlet pipe
16 adjacent to the axle center of power transmission shaft 5, therefore the shaft core position that water inlet pipe 15, the extreme of outlet pipe 16 are swung close to brake 4, even if system
Dynamic device 4 is swung, and it is also minimum that brake 4 puts on water inlet pipe 15, the power on outlet pipe 16, and corresponding, water inlet pipe 15, goes out
The pulling force that water pipe 16 is formed to brake 4 almost can be ignored, and can avoid making because concentricity is bad to the full extent
There is situation about rubbing into brake 4 and water inlet pipe 15, outlet pipe 16, the utility model by using hard material water inlet pipe
15th, outlet pipe 16, its service life is not only can guarantee that, does not interfere with the accuracy of torsion-testing more, and by water inlet pipe 15, water outlet
Pipe 16 is then completely mutual between water inlet pipe 15, outlet pipe 16 and brake 4 located at when be in the position in same axle center with power transmission shaft 5
Do not disturb, can perfectly give an incomparable accurately torque value, in actual applications also can by extend water inlet pipe 15,
The length of outlet pipe 16 weakens pulling force, and water inlet pipe 15, outlet pipe 16 are longer, and the pulling force that water inlet pipe 15, outlet pipe 16 are formed is then
It is smaller, when brake 4 is swung, if concentricity is bad, then bearing and fixed frame 2, biography outside power transmission shaft 5 can be caused
Rub, can avoid rubbing by improving bearing machining accuracy guarantee concentricity between sense frame 3.
It is in laterally uniform annular groove 17 that the periphery of rotor 7, which is provided with some, between annular groove 17, rotor 7 and stator 8
All being put in gap has magnetic, when rotor 7 rotates with power transmission shaft 5, internal magnetic is lined up magnetic linkage by the magnetic line of force, by magnetic
Chain produces the resistance that pulling force is changed into preventing rotor 7 from rotating, and the power is loading moment, and loading moment forms the stator 8 of brake 4
Slight oscillatory, drive torque arm 13 to swing using brake 4, the test of moment of torsion is realized, it can thus be appreciated that the utility model above institute
The structure stated is applicable on different dynamometer machines, such as magnetic dynamometer machine and electric eddy current dynamometer.
The one end of power transmission shaft 5 is provided with grating disc 18, and the photoelectric sensing corresponding with the position of grating disc 18 is provided with sensing frame 3
Device 19, when power transmission shaft 5 rotates, photoelectric sensor 19 just can pass through the grating disc that is rotated with power transmission shaft 5 very first time
18 test out the rotating speed of power transmission shaft 5.
The both sides of torque arm 13 are provided with screw that is mutually symmetrical and being connected with sensing hole 14, screwhole position and pressure sensor
11 upper end positions are corresponding, are bolted with set screw in screw, staff can turn be located at the regulation spiral shells of the both sides of sensing hole 14
Silk makes it, so as to which the width of sensing hole 14 is reduced in deflecting, obtain the amplitude of fluctuation of brake 4 close to the upper end of pressure sensor 11
Limitation, the amplitude of fluctuation of brake 4 is lower, and the pulling force that water inlet pipe 15, outlet pipe 16 are formed is then smaller, plays and ensures moment of torsion accurately
Effect.
