Description
Technical field
The present invention relates to monofocal bearing support structure motor test technology, specifically a kind of monofocal bearing support structure electric motor test device.
Background technology
Monofocal bearing support structure motor has the features such as compact conformation, stable drive, vibration be little because of it and is widely used in Large-power High-Speed, heavy traction kinematic train.Before formally coming into operation, monofocal bearing support structure motor need through series of experiments (comprising type approval test, routine test etc.).At present, the experimental technique of monofocal bearing support structure motor is mainly divided into following two kinds: a kind of is directly be connected with the shaft coupling 14 of load motor 13 by the output shaft of monofocal bearing support structure motor 12 to be tested, and complete test on this basis, as shown in Figure 1.Another kind supports 15 by transition to be connected with the shaft coupling 14 of load motor 13 by the output shaft of monofocal bearing support structure motor 12 to be tested, and complete test on this basis, as shown in Figure 2.Practice shows, above-mentioned two kinds of experimental techniques limit due to self principle, there are the following problems: one, rotor air gap due to monofocal bearing support structure motor is very little (being generally 0.8-1.2mm), cause the centering of the output shaft of monofocal bearing support structure motor and the shaft coupling of load motor (namely right alignment adjusts) difficulty very big, and once centering permissible accuracy cannot be reached, just can there is judder in monofocal bearing support structure motor, thus cause test to carry out in process of the test.Its two, because monofocal bearing support structure motor cannot independent operation, cause when carrying out routine test, monofocal bearing support structure motor must be connected with load motor, thus causes monofocal bearing support structure motor cannot complete independently routine test.Based on this, be necessary to invent a kind of brand-new monofocal bearing support structure motor test technology, easily cause motor generation judder and cannot the problem of complete independently routine test to solve existing monofocal bearing support structure motor test technology.
Summary of the invention
The present invention easily causes motor generation judder and cannot the problem of complete independently routine test to solve existing monofocal bearing support structure motor test technology, provides a kind of monofocal bearing support structure electric motor test device.
The present invention adopts following technical scheme to realize: monofocal bearing support structure electric motor test device, comprises its rear end with the technique rotating shaft of flange face, technique end cap and bearing assembly; Described bearing assembly comprises bearing, front internal sealed ring, rear internal sealed ring, front bearing retainer, rear bearing cover; Wherein, technique end cap is socketed on the lateral surface of the outer ring of bearing; The inner ring of bearing, front internal sealed ring, rear internal sealed ring are all socketed on the lateral surface of technique rotating shaft; The rear end face of front internal sealed ring and the front end face of bearing are close to; The front end face of rear internal sealed ring and the rear end face of bearing are close to; The rear end face of front bearing retainer and the front end face of technique end cap are fixed; The front end face of rear bearing cover and the rear end face of technique end cap are fixed; Labyrinth seal is equipped with between the medial surface of front bearing retainer and the lateral surface of front internal sealed ring, between the medial surface of rear bearing cover and the lateral surface of rear internal sealed ring.
During work, the output shaft end face of the flange face of technique rotating shaft and monofocal bearing support structure motor to be tested is fixed.The stator end stop portion of the end face of technique end cap and monofocal bearing support structure motor to be tested is fixed.Specific works process is as follows: one, when carrying out type approval test, the front end face of technique rotating shaft and the shaft coupling of load motor is fixed, as shown in Figure 4.The output shaft of monofocal bearing support structure motor drives the shaft coupling of load motor to rotate by technique rotating shaft, and completes type approval test on this basis.Two, when carrying out routine test, without the need to monofocal bearing support structure motor is connected with load motor.Because technique rotating shaft support is on bearing, the output shaft of monofocal bearing support structure motor just can carry out independent operation under the supporting role of bearing, and complete independently routine test on this basis.In the process, front internal sealed ring, rear internal sealed ring, front bearing retainer, rear bearing cover can guarantee the sealing of bearing grease.Based on said process, compared with existing monofocal bearing support structure motor test technology, monofocal bearing support structure electric motor test device tool of the present invention has the following advantages: one, monofocal bearing support structure electric motor test device of the present invention is by adopting technique rotating shaft, make the rotor of monofocal bearing support structure motor be provided with shaft extension to export, effectively reduce the centering difficulty of the output shaft of monofocal bearing support structure motor and the shaft coupling of load motor thus, effectively prevent monofocal bearing support structure motor to vibrate in process of the test, thus effectively ensure that normally carrying out of test.Experiment shows, after adopting monofocal bearing support structure electric motor test device of the present invention, the right alignment of the output shaft of monofocal bearing support structure motor and the shaft coupling of load motor is down to 0.1-0.2mm by original 0.4-0.5mm, and the vibration values of monofocal bearing support structure motor when testing is down to 0.8-1.2m/s by original 3.5-6.2m/s.Its two, monofocal bearing support structure electric motor test device of the present invention, by adopting technique end cap and bearing, makes monofocal bearing support structure motor just can complete independently routine test without the need to being connected with load motor.In sum, monofocal bearing support structure electric motor test device of the present invention, by adopting brand new, efficiently solves existing monofocal bearing support structure motor test technology and easily causes motor generation judder and cannot the problem of complete independently routine test.
Further, rotating shaft set bolt, end cap set bolt, bearing cap set bolt is also comprised; Through the edge of the flange face of technique rotating shaft before and after rotating shaft set bolt; Through the end face edge of technique end cap before and after end cap set bolt; The rear end face of front bearing retainer is fixed by the front end face of bearing cap set bolt and technique end cap; The front end face of rear bearing cover is fixed by the rear end face of bearing cap set bolt and technique end cap.During work, the flange face of technique rotating shaft is fixed by the output shaft end face of rotating shaft set bolt and monofocal bearing support structure motor to be tested.The end face of technique end cap is fixed by the stator end stop portion of end cap set bolt and monofocal bearing support structure motor to be tested.Above-mentioned bolt can make fixing more firm, thus normally the carrying out of warranty test further.
Further, the technique through hole that the end face of technique end cap is through before and after offering.During work, testing crew can be fixed and dismounting the flange face of technique rotating shaft and the output shaft end face of monofocal bearing support structure motor to be tested easily by technique through hole, thus effectively improves easy accessibility.
The present invention efficiently solves existing monofocal bearing support structure motor test technology and easily causes motor generation judder and cannot the problem of complete independently routine test, is applicable to monofocal bearing support structure motor test.
