Description
Technical field
The present invention relates to monofocal bearing support structure motor test technology, specifically a kind of monofocal bearing support structure motor novel test device.
Background technology
Monofocal bearing support structure motor is widely used in Large-power High-Speed, heavy traction kinematic train because it has the characteristics such as compact conformation, stable drive, vibration be little.Before formally coming into operation, monofocal bearing support structure motor need pass through series of experiments (comprising type approval test, routine test etc.).At present, the experimental technique of monofocal bearing support structure motor mainly is divided into following two kinds: a kind of is that the output shaft of monofocal bearing support structure motor 12 to be tested directly is connected with the shaft coupling 14 of load motor 13, and complete on this basis test, as shown in Figure 1.Another kind is to support 15 by transition the output shaft of monofocal bearing support structure motor 12 to be tested is connected with the shaft coupling 14 of load motor 13, and completes test on this basis, as shown in Figure 2.Practice shows, above-mentioned two kinds of experimental techniques are because self principle is limit, there are the following problems: one, rotor air gap very little (being generally 0.8-1.2mm) due to monofocal bearing support structure motor, cause centering (the being the right alignment adjustment) difficulty of shaft coupling of the output shaft of monofocal bearing support structure motor and load motor very big, once and can't reach the centering permissible accuracy, judder just can occur in monofocal bearing support structure motor in process of the test, thereby causes test to carry out.Its two, can't independent operation due to monofocal bearing support structure motor, cause when carrying out routine test, monofocal bearing support structure motor must be connected with load motor, thereby causes the monofocal bearing support structure motor can't the 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 problem that can't the 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 problem that can't the complete independently routine test in order to solve existing monofocal bearing support structure motor test technology, and a kind of monofocal bearing support structure motor novel test device is provided.
The present invention adopts following technical scheme to realize: monofocal bearing support structure motor novel test device comprises technique rotating shaft, technique end cap and the bearing assembly of its rear end with flange face; Described bearing assembly comprises bearing, front internal sealed ring, rear internal sealed ring, front bearing retainer, rear bearing cover; Wherein, the 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 all are 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 front end face of the rear end face of front bearing retainer and technique end cap is fixed; The rear end face of the front end face of rear bearing cover and technique end cap is fixed; Between the medial surface of front bearing retainer and the lateral surface of front internal sealed ring, between the lateral surface of the medial surface of rear bearing cover and rear internal sealed ring, be equipped with labyrinth seal.
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.The specific works process is as follows: one, when carrying out type approval test, the shaft coupling of the front end face of technique rotating shaft and load motor is fixed, as shown in Figure 4.The shaft coupling that the output shaft of monofocal bearing support structure motor drives load motor by the technique rotating shaft is rotated, and completes type approval test on this basis.Two, when carrying out routine test, without monofocal bearing support structure motor is connected with load motor.Due to the technique rotating shaft support, 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 this process, front internal sealed ring, rear internal sealed ring, front bearing retainer, rear bearing cover can be guaranteed the sealing of bearing grease.Based on said process, with existing monofocal bearing support structure motor test technology, compare, monofocal bearing support structure motor novel test device of the present invention has following advantage: one, monofocal bearing support structure motor novel test device of the present invention is by the adopting process rotating shaft, make the rotor of monofocal bearing support structure motor there is shaft extension output, effectively reduce thus the centering difficulty of the shaft coupling of the output shaft of monofocal bearing support structure motor and load motor, effectively prevented monofocal bearing support structure motor vibration-generating in process of the test, thereby effectively guaranteed normally carrying out of test.Experiment shows, after adopting monofocal bearing support structure motor novel 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 being tested is down to 0.8-1.2m/s by original 3.5-6.2m/s.Its two, monofocal bearing support structure motor novel test device of the present invention is by adopting process end cap and bearing, but makes monofocal bearing support structure motor without be connected just complete independently routine test with load motor.In sum, monofocal bearing support structure motor novel test device of the present invention is by adopting brand new, efficiently solves existing monofocal bearing support structure motor test technology and easily causes motor generation judder and problem that can't the complete independently routine test.
Further, also comprise rotating shaft set bolt, end cap set bolt, bearing cap set bolt; Rotating shaft set bolt front and back are through the edge of the flange face of technique rotating shaft; End cap set bolt front and back are through the end face edge of technique end cap; 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, thereby further warranty test normally carries out.
Further, the technique through hole that the end face of technique end cap connects before and after offering.During work, testing crew can be easily be fixed and dismantles the output shaft end face of the flange face of technique rotating shaft and monofocal bearing support structure motor to be tested by the technique through hole, thereby has effectively improved easy accessibility.
The present invention efficiently solves existing monofocal bearing support structure motor test technology and easily causes motor generation judder and problem that can't the complete independently routine test, is applicable to monofocal bearing support structure motor test.
