Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Fig. 1 is the structural representation of a kind of micro motor rotating speed torque detector of providing of the utility model embodiment.
A kind of micro motor rotating speed torque detector, comprise base 1, described base 1 top is provided with base plate 2, described base plate 2 middle parts are provided with torque and speed sensors 3, described torque and speed sensors 3 front ends are connected with and treat measured motor 10 by axle 12, and torque and speed sensors 3 rear ends are connected with pulley 4 by axle 12.The axle 12 of described pulley 4 one sides is provided with the bearing 5 that supports by bearing base.Described base 1 is provided with magnetic powder brake 9, and magnetic powder brake 9 is connected with pulley 4 and torque and speed sensors 3 by axle 12.4, described magnetic powder brake 9 and pulley are provided with reductor 8, and reductor 8 is installed on base 1.The size of loading moment, the output speed of tested motor product adopt torque and speed sensors to measure, and the size of current of electrical consumption is measured and shown by meter specially by Hall current sensor.Because the rotating speed for the treatment of measured motor 10 is higher, and therefore the turn up of magnetic powder brake adopts reductor 8 to carry out speeds match less than requiring.
Micro motor in the utility model specific embodiment, refer to that diameter is less than 160mm or the rated power motor less than 750W.
Magnetic powder brake 9 in micro motor rotating speed torque detector loads for moment, and the moment size of magnetic powder brake 9 changes according to the variation of input voltage value.This tester requires the moment that loads: 0~± 8Nm, adjustable continuously, to set up moment and should keep enough degree of stability, torque fluctuations is less than 1%, and measuring accuracy is higher than 1%; The rotating speed for the treatment of measured motor 10 reaches 13000rpm.Because the motor maximum speed is higher, therefore by acceleration and deceleration mechanism between magnetic powder brake 9 and front end assemblies, realize.
According to the size of the rotating speed for the treatment of measured motor 10, loading moment and the maximum speed requirement of powder clutch 9, the output torque of the reductor 8 of selection > 50Nm, reduction gear ratio is 5, the minimum 13000r/min of input shaft maximum speed.
Due to the reduction gear ratio of reductor be 5 and the maximum speed of tested motor be 13000rpm, therefore the maximum speed of magnetic powder brake should be 2600rpm, and the rated speed of selected magnetic powder brake is 2000rpm, and magnetic powder brake 9 need to be operated in overload condition like this.But due to 13000rpm, be the maximum speed of testing of electric motors, tested motor runs on below 10000rpm usually, and not long-time running simultaneously is in maximum speed, and therefore selected magnetic powder brake and reductor is feasible.
Described pulley 4 outsides are provided with the counterweight load maintainer 7 of L-type, and described counterweight load maintainer 7 is installed on base plate 2.Described counterweight load maintainer 7 ends are provided with suspension ring 6.Realization is carried out little moment of torsion and is loaded test in the larger range of speeds, therefore the mode that adopts counterweight to load, counterweight is positioned on counterweight load maintainer 7 or suspension ring 6, and makes it corresponding with corresponding pulley 4, make the moment for the treatment of measured motor 10 produce the variation that can correspondingly detect.
Described axle 12 is the sectional type axis body, and connects by some shaft couplings 11.It is upper that all assemblies all are arranged on the test stage body that levelness is higher (being comprised of base and base plate), and because the right alignment of this test board is had relatively high expectations, so each inter-module selects spring coupling to connect, effectively to guarantee parameter index.
Because the right alignment of this tester is had relatively high expectations, therefore can select the spring coupling of German ROTEX company, ROTEX-GS series is without the backlash shaft coupling, and this serial shaft coupling is comprised of three parts, can axially install easily.Under prestressed effect, guarantee the transmission without backlash, improved greatly the dynamic perfromance of kinematic train.The direct tooth type elastic body is installed under prestress, surface of elastomer bears certain precompression, thereby makes the rigidity of shaft coupling system fine, and Elastic Teeth can compensate alignment error.These characteristics can guarantee the shaft coupling smooth long term running.
Torque and speed sensors 3 is connected with test instrumentation by cable, to show moment and rotating speed.This test instrumentation has following function: display window, 35 display windows are provided, and show respectively the measured value of torque, rotating speed, power, the torque maximum value in changeable display measurement process of while, and provide positive and negative moment of torsion indication; Zeroing; Function with sensor measurement zero point correction; Range is set; Instrument provides the user input capability of range setting, can guarantee the versatility of instrument and sensor, need not specially demarcate; Report to the police: the user can arrange the alarming value of torque, rotating speed, and instrument possesses alarm indication function, and alarm output signal is provided; Print: but external printer carries out the real time data printing; Communication: standard RS-232 interface and communication protocol are provided; Power supply detects and resets: avoid the deadlock phenomenon that power supply disturbs, fluctuation causes; Parameter is preserved: all kinds of parameters that can preserve setting; Signal Isolation Technology is all adopted in input and output, has certain antijamming capability.
During actual the use, this tester is carried out to the connection of high-torque loading scheme according to working specification, through test of many times, obtain tester and have intrinsic loading moment, it is worth below 0.2Nm, along with the increase built-in inertia loading moment of single working time is reducing, minimum value is 0.152Nm.In the situation that 0.152Nm built-in inertia loading moment, motor speed is set up under 6000rpm, increase gradually the given voltage of magnetic powder brake 9 to 2.0V, the torque measurement indicating value is 0.357Nm, its linearity is good, with the scope of little moment loading scheme, overlap, meet the measurement range of technical indicator regulation.
The utility model is by the structural design of innovation, on the basis of the accuracy that has guaranteed the test of motor speed moment, accomplished simple in structurely, and result of use is good, the lightweight and portable in volume compactness, and cost is lower, and economy and social benefit be good, and suitable large-scale promotion is used.
The utility model is described by embodiment, and those skilled in the art know, in the situation that do not break away from spirit and scope of the present utility model, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under guidance of the present utility model, can modify to adapt to concrete situation and material and not break away from spirit and scope of the present utility model these features and embodiment.Therefore, the utility model is not subjected to the restriction of specific embodiment disclosed herein, and all interior embodiment of claim that fall into the application belong to the scope that the utility model is protected.
