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 torque rotary speed proving installation, comprise body 100, torque rotary speed sensor 200, electrically operated valve fixture 300, coupling shaft 400, vertical type magnetic powder brake 500.Electrically operated valve fixture 300 is connected by spring coupling with coupling shaft 400, relaxes and impacts and absorb vibration, can stably measured result, contract measurement error.On body, 100 are provided with axis hole 110, be fixed on after the sheathed bearing of coupling shaft 400 in axis hole 110, 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 board on industrial computer.The output terminal of torque rotary speed sensor 200 connects vertical type magnetic powder brake 500 input end, and vertical type magnetic powder brake 500 is fixed on bottom body 100.Vertical type magnetic powder brake 500 loads load by programmable power supply, and programmable power supply connects the industrial computer with signal plate card.Realize the effect of this device in the production automation.
Vertical type magnetic powder brake 500 is the magnetic powder brake after structure is improved, and as shown in Fig. 2 to 3, its rotor 1, comprises the convex annular mesa-shaped 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.Sedimentation transitional zone 122 is provided with between high position portion 121 and low level portion 123.The upper and lower surface of sedimentation transitional zone 122 on the shaft section of rotor block 12 linearly.Sedimentation transitional zone 122 and the angle between high-order portion 121 and low level portion 123 retain wedge angle and arrange.
The vertical type magnetic powder brake that the 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 surface is the straight line of corresponding sedimentation transitional zone 122 on 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 surface is the straight line of corresponding sedimentation transitional zone 122 on shaft section.Above-mentioned angle position also retains wedge angle and arranges.
Be provided with first cavity 4 corresponding with rotor block 12 shape between above-mentioned upper and lower magnetic pole 2,3, magnetic 6 is arranged on low level portion 123 side of the first cavity 4 in sedimentation transitional zone 122.In addition, be the second cavity 5 with the coaxial ring cavity arranged of the first cavity 4 between upper and lower magnetic pole 2,3, be inside 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 upper and lower axis hole after the bearing set of armature spindle 11 two ends.
Because rotor block 12 has one-level from high-order portion 121 to the sedimentation transitional zone 122 in low level portion 123.Lower magnetic pole 3 has with the corresponding setting of rotor block 12 shape and sedimentation step 31.Upper magnetic pole 2 has the outstanding step 21 corresponding with rotor block 12 shape.This makes the magnetic 6 being located at low level portion 123 not easily fall in the bearing at armature spindle 11 place, therefore can vertically install, and extends the serviceable life of magnetic powder brake, improves the stability of magnetic powder brake.The upper and lower surface linearly transition of sedimentation transitional zone 122 on shaft section, and retain the setting of transition wedge angle, magnetic 6 is more not easily fallen in the turning axle at armature spindle 11 place.
Be provided with O-ring seal 9 between the upper and lower magnetic pole 2,3 of the present embodiment and armature spindle 11, prevent the magnetic 6 draining to bearing place from entering in turning axle further.
During work, magnetizing coil 7 galvanization, namely operating magnetic field flux is produced in upper magnetic pole 2 and lower magnetic pole 3, magnetic 6 in first cavity 4 is that chain couples together along flow direction, form magnetic chain, magnetic powder brake by the lower surface of now magnetic 6 and rotor block 12, upper magnetic pole 2, lower magnetic pole 3 upper surface between friction force and magnetic chain between shearing resistance carry out transmitting torque, to reach the object of braking.
When described magnetizing coil 7 cuts off electric current, operating magnetic field flux disappears with the disappearance of exciting curent, magnetic 6 is in loose condition (of surface) under gravity, magnetic 6 drops on the upper surface of lower magnetic pole 3, because lower magnetic pole 3 has the setting such as sedimentation step 31 grade of respective rotor body 12 setting, make magnetic 6 can not enter the first cavity 4 near armature spindle 11 place, therefore magnetic 6 can not enter in bearing.
Regulate the size of exciting curent in magnetizing coil 7, can change the action effect of magnetic 6 transmitting torque, when exciting curent is larger, then the moment of torsion of magnetic 6 transmission is larger, larger to the friction force of rotor block 12; When exciting curent is less, then the moment of torsion of magnetic 6 transmission is less, less to the friction force of rotor block 12, thus can reach the object of brake rotors axle 11.
Magnetism-isolating loop 8 is provided with in addition between first cavity 4 of vertical type magnetic powder brake provided by the invention and the second cavity 5, block magnetic field in the inner conducting of upper and lower magnetic pole 2,3, thus form magnetic flux between the first cavity 4 and the second cavity 5, and rotor block 12 is integrally formed operating magnetic field flux.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, these also should be considered as within protection scope of the present invention.
