Embodiment
Below in conjunction with accompanying drawing, with regard to an embodiment of the present utility model, structure of the present utility model and working method are described further.
As shown in Figure 1, the utility model provides a kind of vertical torque rotary speed proving installation, comprises body 100, torque rotary speed sensor 200, electrically operated valve anchor clamps 300, coupling shaft 400, vertical magnetic powder brake 500.Electrically operated valve anchor clamps 300 and coupling shaft 400 are connected by spring coupling, relax and impact and absorb vibration, can the stably measured result, dwindle measuring error.100 are provided with axis hole 110 on the body, be fixed in the axis hole 110 behind the coupling shaft 400 sheathed bearings, the other end of coupling shaft 400 connects the input end of torque rotary speed sensor 200, torque rotary speed sensor 200 has photoelectric encoder, and the output terminal of torque rotary speed sensor 200 connects the signals collecting integrated circuit board on the industrial computer.The output terminal of torque rotary speed sensor 200 connects vertical magnetic powder brake 500 input ends, and vertical magnetic powder brake 500 is fixed on body 100 bottoms.Vertical magnetic powder brake 500 loads load by programmable power supply, and programmable power supply connects the industrial computer that has the signal plate card.Realize the effect of this device in the production automation.
Vertical magnetic powder brake 500 is for through the magnetic powder brake after the architecture advances, and shown in Fig. 2 to 3, its rotor 1 comprises the annular boss shape rotor block 12 of armature spindle 11 and coaxial fixed rotor axle 11.Rotor block 12 comprises high-order portion 121 and low level portion 123.Be provided with sedimentation transitional zone 122 between high position portion 121 and the low level portion 123.The upper and lower surface of sedimentation transitional zone 122 on the shaft section of rotor block 12 linearly.Angle between sedimentation transitional zone 122 and high-order portion 121 and the low level portion 123 keeps the wedge angle setting.
The vertical magnetic powder brake that present embodiment provides also comprises the lower magnetic pole 3 of sheathed armature spindle 11, is provided with the sedimentation step 31 of corresponding sedimentation transitional zone 122.Sedimentation step 31 upper surfaces are the straight line of corresponding sedimentation transitional zone 122 at shaft section.The last magnetic pole 2 of sheathed armature spindle 11 is provided with the outstanding step 21 of corresponding sedimentation transitional zone 122.Outstanding step 21 lower surfaces are the straight line of corresponding sedimentation transitional zone 122 at shaft section.Above-mentioned angle position also keeps the wedge angle setting.
Be provided with first cavity 4 corresponding with rotor block 12 shapes between the above-mentioned upper and lower magnetic pole 2,3, magnetic 6 is arranged on first cavity 4 in low level portion 123 1 sides of sedimentation transitional zone 122.In addition, the ring cavity with the 4 coaxial settings of first cavity between the upper and lower magnetic pole 2,3 is second cavity 5, in be provided with magnetizing coil 7.
Last magnetic pole 2 is provided with upper shaft hole, and lower magnetic pole 3 is provided with lower shaft hole, is fixed in the upper and lower axis hole behind the armature spindle 11 two ends bearing sets.
Because rotor block 12 has the sedimentation transitional zone 122 of one-level from high-order portion 121 to low level portion 123.Lower magnetic pole 3 has the sedimentation step 31 with the corresponding setting of rotor block 12 shapes.Last magnetic pole 2 has the outstanding step 21 corresponding with rotor block 12 shapes.This makes the magnetic 6 of being located at low level portion 123 be difficult for falling in the bearing at armature spindle 11 places, thus can vertically install, and prolonged the serviceable life of magnetic powder brake, improved the stability of magnetic powder brake.The upper and lower surface linearly transition of sedimentation transitional zone 122 on shaft section, and keep the setting of transition wedge angle, make that magnetic 6 is difficult for falling in the turning axle at armature spindle 11 places more.
The upper and lower magnetic pole 2 of present embodiment, 3 and 11 of armature spindles be provided with O-ring seal 9, prevent that further the magnetic 6 that drains to the bearing place from entering in the turning axle.
During work, magnetizing coil 7 galvanizations, namely produce the work magnetic flux in last magnetic pole 2 and the lower magnetic pole 3, magnetic 6 in first cavity 4 is chain along flow direction and couples together, form the magnetic chain, magnetic powder brake transmits moment of torsion by the friction force between the upper surface of the lower surface of this moment magnetic 6 and rotor block 12, last magnetic pole 2, lower magnetic pole 3 and the shearing resistance between the magnetic chain, to reach the purpose of braking.
When described magnetizing coil 7 cuts off electric current, the work magnetic flux disappears with the disappearance of exciting curent, magnetic 6 is in loose condition (of surface) under the effect of gravity, magnetic 6 drops on the upper surface of lower magnetic pole 3, because lower magnetic pole 3 has sedimentation step 31 settings such as grade that respective rotor body 12 arranges, make magnetic 6 can not enter first cavity 4 near armature spindle 11 places, so magnetic 6 can not enter in the bearing.
Regulate the size of exciting curent in the magnetizing coil 7, can change the action effect that magnetic 6 transmits moments of torsion, when exciting curent is more big, then the moment of torsion that transmits of magnetic 6 is just more big, and is just more big to the friction force of rotor block 12; When exciting curent is more little, then the moment of torsion that transmits of magnetic 6 is just more little, and is just more little to the friction force of rotor block 12, thereby can reach the purpose of brake rotors axle 11.
Be provided with magnetism-isolating loop 8 between first cavity 4 of the vertical magnetic powder brake that provides of the utility model and second cavity 5 in addition, blocking-up magnetic field is in upper and lower magnetic pole 2,3 inner conductings, thereby form magnetic flux and rotor block 12 integrally formed work magnetic fluxs at first cavity 4 and 5 of second cavitys.
The above only is optimal way of the present utility model; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within the protection domain of the present utility model.
