Description
Technical field
The utility model relates to a kind of motor performance proving installation, especially a kind of shellless motor performance testing device.
Background technology
The energy consumption index of products such as refrigerator, air conditioner, electric bicycle, electric tool is all extremely paid attention in countries in the world, and requires more and more stricter.For this reason, must accurately match motor, and this depends on and measures motor performance exactly: in torque, rotating speed and the output power of unloaded, stall and each POL.
The common feature of the product of these industries: motor does not have parts such as own independent shell, axle, bearing, end cap, and the main frame of it and machine is integrated, parts such as common enclosure, axle, bearing, end cap.Do not purchase complete common electric machine from electrical machinery plant during production, only purchase stator and rotor (this paper is referred to as shellless motor).The checkout equipment of this type of motor has the equipment of shell motor basic identical with detection at present, usually by forming: stabilized voltage supply 6 with the lower part, dynamometer machine 2, Dynamometer Control device 3, by measured motor 1, electrical parameter measuring instrument 5, computing machine 4 (handling test data uses), see Fig. 1, its detection method also is the detection method that shell motor is arranged by common: detect complete common electric machine Zhao and the shell additionally assorted, axle, bearing, parts such as end cap have changed the practical structures of machine, the intermediate link and the manually-operated of machine are too much, these factor fluctuations are very big, proportion is huge in the micromachine test result, produce gross error, it is even more serious especially to detect the relative error that produces for micromachine.
And these errors cause accurately matching motor, if torque, rotating speed and output power are less than normal, then the function of product does not reach requirement; If torque, rotating speed and output power are bigger than normal, then energy consumption is up to standard or be in the competition inferior position.Because the method for this key link of test is improper, this important indicator of product energy consumption of a lot of enterprises becomes weakness, directly causes product specification lower.
The utility model content
The purpose of this utility model is:
The technical solution of the utility model is: provide a kind of shellless motor proving installation, be different from traditional device, can be used for the shellless motor test of every profession and trade, improve the testing precision of shellless motor.
A kind of shellless motor proving installation, comprise test platform, be installed in the dynamometer machine on the test platform, it is characterized in that: this device also comprises the bearing seat that is installed on the test platform, the general-purpose machine main shaft is installed in the bearing in the bearing seat, and an end of general-purpose machine main shaft is connected with the test axle of dynamometer machine, and the other end is a test lead, be useful on the anchor clamps that rotor is installed on the test lead, outside test lead, be with the stator that to remove.
Optimal technical scheme of the present utility model is as follows:
Preferably, described bearing seat is in main spindle box, and main spindle box is fixed on the test platform.
Preferably, described anchor clamps are included in threaded hole, the shaft shoulder on the test lead general-purpose machine main shaft, axle sleeve and the baffle plate of axle sleeve outside test lead general-purpose machine main shaft on the test lead general-purpose machine main shaft end face, having through hole, bolt to pass through hole in the middle of the baffle plate is fixed on baffle plate and axle sleeve on the general-purpose machine main shaft.
The beneficial effects of the utility model are as follows:
1, traditional technical scheme needs assembling motor at every turn, axle, bearing and end cap all need be prepared many, the difference of diameter embodies the difference of end-play each other, sums up in the point that the power of motor fluctuation can reach 10W (reason of preparing many is because built-up time is long, needs the assembling while testing).And use the measurement device of the present utility model running part of not resetting, and this is a constant, fluctuation is 0.
2, the same axis of traditional technical scheme, the difference of the actual allotment of each its end play of assembling embodies the difference of end-play, make degree of flexibility produce dramatic difference, need veteran machine maintenance master worker to assemble adjustment, sum up in the point that the power of motor fluctuation also surpasses 30W.And use the measurement device of the present utility model running part of not resetting, and this is a constant, fluctuation is 0.
3, need to bearing filling railway grease during the each assembling motor of traditional technical scheme, must be just right, otherwise these high-revolving motor or burn bearings, or power of motor soars, and fluctuation can reach 15W.And use the measurement device of the present utility model running part of not resetting, and this is a constant, fluctuation is 0.
4, will be connected with dynamometer machine with shaft coupling behind the traditional each assembling motor of technical scheme, the inclination of two between centers and dislocation can cause the power of motor 2～5W that fluctuates.And use the measurement device of the present utility model running part of not resetting, and this is a constant, fluctuation is 0.
Behind the each assembling motor of traditional technical scheme, can cause power of motor test value fluctuation 10W～40W, can reach 70W individually, and the power of motor of all size of freezer compressor only have 50～150W.Therefore, can't accurately match the indexs such as energy consumption of motor, product, competitiveness of product is lower at all, and total undulating quantity of measurement device of the present utility model is no more than 10W, has improved the measuring accuracy of shellless motor.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the system's connection layout that detects motor device in the prior art.
Fig. 2 is the front view of the utility model shellless motor proving installation embodiment.
