Embodiment
Below in conjunction with accompanying drawing, with regard to one embodiment of the invention, structure of the present invention and working method are described further.
As shown in Figure 1, the invention provides a kind of vertical torque rotary speed proving installation, comprise 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, and the contract measurement 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 is with 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 with 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 section 121 and low level section 123.Be provided with sedimentation transitional zone 122 between high position section 121 and the low level section 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 section 121 and the low level section 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 upper 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 the first cavity 4 in low level section 123 1 sides of sedimentation transitional zone 122.In addition, the ring cavity with the 4 coaxial settings of the first cavity between the upper and lower magnetic pole 2,3 is the second cavity 5, in be provided with magnetizing coil 7.
Upper 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 section 121 to low level section 123.Lower magnetic pole 3 has the sedimentation step 31 with the corresponding setting of rotor block 12 shapes.Upper magnetic pole 2 has the outstanding step 21 corresponding with rotor block 12 shapes.This is so that be located at the magnetic 6 of low level section 123 and 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, so 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 upper magnetic pole 2 and the lower magnetic pole 3, magnetic 6 in the first cavity 4 is chain along flow direction and couples together, form the magnetic chain, magnetic powder brake comes transmitting torque by the friction force between the upper surface of the lower surface of this moment magnetic 6 and rotor block 12, upper 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 action of gravitation, 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 the 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 of magnetic 6 transmitting torques, when exciting curent is larger, then the moment of torsion that transmits of magnetic 6 is just larger, and is just larger to the friction force of rotor block 12; When exciting curent is less, then the moment of torsion that transmits of magnetic 6 is just less, and is just less 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 the first cavity 4 of vertical magnetic powder brake provided by the invention and the second cavity 5 in addition, blocking-up magnetic field is in upper and lower magnetic pole 2,3 inner conductings, thereby form magnetic flux at the first cavity 4 and 5 of the second cavitys, and rotor block 12 integrally formed work magnetic fluxs.
The above only is optimal way of the present invention; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the invention design; can also make some similar distortion and improvement, these also should be considered as within protection scope of the present invention.
