Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 6, a kind of magnetic hysteresis dynamometer machine, comprise base 1, described base 1 is provided with fore-stock 11 and medium-height trestle 12, described fore-stock 11 and medium-height trestle 12 are respectively arranged with bracket holes 13, described bracket holes 13 is provided with rolling bearing 16, also comprise hysteresis brake 2, rotation axis 3, described rotation axis 3 passes the rolling bearing 16 of fore-stock 11 successively, the rolling bearing 16 of hysteresis brake 2 and medium-height trestle 12, one end of described rotation axis 3 is provided with sensing device 4, described sensing device 4 is connected with control circuit 5, described control circuit 5 is provided with for connecting the transmit port 6 of PC.Principle of work of the present utility model is: one end of rotation axis 3 is connected with test motor by shaft coupling, its connection of the other end be sensing device 4, described hysteresis brake 2 is comprised of two elements: the empty cup rotor 22 that netted magnetic pole stator 21 and magnetic steel are made, these two elements are assembled together by rotation axis 3 but do not contact with each other formation air gap, before not switching on, rotor 22 and rotating shaft can freely be rotated, after stator 21 inner ring energisings, stator 21 magnetic poles just produce magnetic field, corresponding air gap is capable becomes a flux areas to attract each other, rotor 22 is subject to the suction of stator 21, make to produce between rotor 22 and stator 21 a magnetic hysteresis effect, sensing device 4 can be by the moment of torsion detecting, the data such as rotating speed are sent to control circuit 5, control circuit 5 passes through transmit port 6 by correlated results, instant playback is on the display of PC, in the utility model, the main hysteresis brake 2 that adopts coordinates with sensing device 4, it is simple in structure, measure precisely, simultaneously, its simple structure makes cost control have greater advantage, thereby make this equipment there is cheap cost, be convenient to promote the use of widely, the transmit port being connected with PC 6 that it is exclusive, when work, Simultaneous Monitoring test result more easily, in sum, this equipment has good novelty and creativeness, also have more preferably practicality.
Conventionally, general sensor, particularly torque sensor 41, and when testing different motors, its torque is not certain, if the excesssive gap of this torque sensor 41, can cause the prolongation of sensitive time, the data of induction comparatively be lagged behind, if the gap of this torque sensor 41 is too small, easily make the data of induction not accurate, occur larger machine error; In the technical program, in order to make sensed data more accurate, so, described sensing device 4 comprises the torque sensor 41 that is arranged at rotation axis 3, described torque sensor 41 comprises adjuster bar 411, and the both sides of described adjuster bar 411 are provided with for adjusting the eccentric nut 43 with bearing of described torque sensor 41 clearance control; After being provided with this eccentric nut 43, just can adjust according to the preset torque of tested motor, adjust fixed position and tolerance clearance that eccentric nut 43 namely regulates torque sensor, reduce machine error; Meanwhile, described rotation axis 3 is provided with disk 31, and described sensing device 4 also comprises that described photoelectric sensor 44 can test out by the rotating speed of disk 31 rotating speed of motor for responding to the photoelectric sensor 44 of described disk 31 rotating speeds.
Obviously, as dynamometer machine, after the longer time of work, dynamometer machine there will be overheated situation, and the overheated meeting of checkout equipment has influence on the accuracy that detects data, so in the situation that described hysteresis brake 2 comprises stator 21 and rotor 22, described stator 21 is provided with interval trough, described rotor 22 is arranged in interval trough, one end of described stator 21 is connected with air-cooled lid 23, and described air-cooled lid 23 is connected with air cooling equipment 7, and the other end of described stator 21 is connected with fixed cap 24.Furtherly: described air cooling equipment 7 comprises the ajutage 71 that is arranged on described air-cooled lid 23 sidewalls, described ajutage 71 is connected with fan blower 72, certainly, this ajutage 71 also can be set to the tubing of 90 degree elbows, this ajutage 71 is connected with air-cooled lid 23 sidewalls, then through medium-height trestle 12, an after-poppet is set after medium-height trestle 12 again, described after-poppet is used for installing fan blower 72 etc.Described fixed cap 24 is connected with wind disk 25, described fixed cap 24 is provided with the axis hole with described rotation axis 3 clearance fit, described wind disk 25 is connected with wind scooper 26, during work, by fan blower 72, cold wind is sent into air-cooled lid 23 by ajutage 71, cold wind enters one end of detent from air-cooled lid 23, then from the fixed cap 24 of the other end, discharge and form air-flow, because cold wind is by hot environment, the phenomenon that easily occurs water droplet, so, when air-flow is discharged from fixed cap 24, contact with wind disk 25, form and reflux, and water droplet is the in the situation that of gravity, from wind disk 25, fall and enter in the lump wind scooper 26 together with discharging air-flow, thereby having avoided air-flow to carry water droplet is sprayed directly on by measured motor, there is protective effect.
Conventionally, moment of torsion inductor has certain induction stroke, when the moment of torsion of tested motor has exceeded the maximum induction stroke of moment of torsion inductor, at this moment will cause the damage of moment of torsion inductor, as further improvement, described base 1 is provided with limited block 14, and described limited block 14 is provided with recess 141, and described fixed cap 24 is provided with the swinging block 15 that stretches into described recess 141.Further, described recess 141 is provided with for regulating bolt 142 and the hold-down nut 143 of described swinging block 15 pendulum angles.Like this; when test motor; when surveyed motor torsional moment exceeds the range of torque sensor 41; due to the effect of limited block 14, the angle limits that its swinging block 15 swings is the distance that is recess 141 to the maximum, thus the damage of having protected torque sensor 41 to occur because of overload; at described recess 141, be provided with bolt 142 simultaneously; so just can further adjust the pendulum angle of swinging block 15, it is simple in structure, and result of use is good.
Because the interval between sensing device 4 and hysteresis brake 2 is less, like this, the heat that hysteresis brake 2 distributes is just easily delivered to sensing device 4, while there is larger difference variation in sensing device 4, will cause the data that detect to occur abnormal, as further heat insulation processing, between described hysteresis brake 2 and sensing device 4, be provided with heat insulation 8, in the technical program, as better a kind of selection, be, described heat insulation 8 is bakelite piece, certainly, also can adopt other heat-barrier material, as: pottery etc.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
