Description
Technical field
The utility model relates to a kind of mounting structure of resolver, is specifically related to a kind of mounting structure for electric motor coach direct driving motor resolver.
Background technology
Direct driving motor is the important component part of electric motor coach, and its working speed, torque are to be controlled according to the feedback signal that is placed in the resolver of machine shaft end by electric machine controller.Resolver is comprised of stator and rotor.The rotor of current resolver is fixed on machine shaft by a connecting axle, and with the synchronized rotation of rotating shaft.Connecting axle one end is processed into screw thread and is coordinated with shaft central hole.While moving, often there is the problems such as motor speed can not improve, moment of torsion can not add after direct driving motor entrucking.Find after deliberation, these problems are because of the stator of resolver and rotor eccentricity, signal feedback error to be caused.Existing rotating transformer mounting structure cannot guarantee resolver stator and rotor concentric, and be not easy to assembling.
Utility model content
The purpose of this utility model is to provide a kind of mounting structure for electric motor coach direct driving motor resolver, stator and the height of rotor when work that not only can guarantee resolver are concentric, thereby make resolver can be for a long time accurately feedback signal, guarantee that direct driving motor normally moves, be also convenient to the installation of resolver.
For achieving the above object, the utility model has adopted following technical scheme: a kind of mounting structure for electric motor coach direct driving motor resolver, comprise back end cover for motor, the rotating shaft being connected with back end cover for motor by bearing, be installed in connecting axle and resolver in rotating shaft, described connecting axle is fixed in rotating shaft by seam, and described motor rear end covers to be installed with and revolves change support.
Described revolving becomes support and by seam, is fixed on motor rear end and covers.
Described resolver comprises the resolver rotor being installed on connecting axle and is installed in the resolver stator revolving on change support.
Described motor rear end covers to be installed with and revolves change enclosing cover.
Advantage of the present utility model:
(1) the utility model is fixed on connecting axle in rotating shaft by the seam of connecting axle, and at motor rear end, covers to be provided with and revolve change support, and the seam that becomes support by revolving is fixed in motor rear end and covers.By the fixed form of seam, not only can play good positioning action, height in the time of also can effectively guaranteeing resolver stator and resolver rotor relative movement is concentric, avoids resolver to cause feedback signal error large because of eccentric, affects motor normal operation.
(2) the utility model revolves change support by covering at motor rear end to arrange, and revolves and become support and by seam, be fixed on motor rear end and cover, and can realize assembling and the replacing of resolver or connecting axle without dismounting back end cover for motor.This has not only guaranteed the assembly precision of rear bearing and bearing of rear end cover chamber, has also improved motor reliability of operation.
The utility model not only can guarantee the stator of resolver and the height of rotor when work concentric, make the long-time accurately feedback signal of resolver, guarantee that direct driving motor normally moves, be also convenient to the installation of resolver.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model connecting axle;
Fig. 3 is that the utility model revolves the structural representation that becomes support.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of mounting structure for electric motor coach direct driving motor resolver as shown in Figure 1, Figure 2, Figure 3 shows, comprises that back end cover for motor 1, the rotating shaft 2 being connected with back end cover for motor 1 by bearing are installed in connecting axle 7 and resolver in rotating shaft 2.Connecting axle 7 is fixed in rotating shaft 2 by seam, is installed with to revolve to become support 3 on back end cover for motor 1.Specifically, seam 8 is provided in a side of on connecting axle 7, and the end of rotating shaft 2 and connecting axle 7 are fixed by screw, and the seam 8 of connecting axle 7 plays good positioning action.
Further, revolving change support 3 is fixed on back end cover for motor 1 by seam.Specifically, revolving change support 3 arranges for resolver convenient for assembly.As shown in Figure 3, revolve change support 3 and be provided with seam 11, play good positioning action.
Further, resolver comprises the resolver rotor 5 being installed on connecting axle 7 and is installed in the resolver stator 4 revolving on change support 3.Specifically, resolver stator 4 is built in and revolves on the installation site 10 that becomes support 3, and fixes by screw; Resolver rotor 5 is placed on the installation site 9 of connecting axle 7, and fixes by screw.Seam fixed form by connecting axle 7 and revolve setting and the seam fixed form thereof that becomes support 3, has guaranteed that the rotor 5 of resolver and the height of stator 4 when relative motion are concentric, avoids resolver to cause excursions on feedback large because of bias.
Further, on back end cover for motor 1, be installed with and revolve change enclosing cover 6.Specifically, revolve change enclosing cover 6 and be fixed on back end cover for motor 1 by screw, play the effect of protection resolver.
In sum, the utility model is fixed on connecting axle 7 in rotating shaft 2 by the seam 8 of connecting axle 7, and on back end cover for motor 1, is provided with to revolve and becomes support 3, and the seam 11 that becomes support 3 by revolving is fixed on back end cover for motor 1.By the fixed form of seam, not only can play good positioning action, height in the time of also can effectively guaranteeing resolver stator 4 and 5 relative motion of resolver rotor is concentric, avoids resolver to cause feedback signal error large because of eccentric, affects motor normal operation.In addition, by arranging to revolve, become support 3 on back end cover for motor 1, and revolve and become support 3 and be fixed on back end cover for motor 1 by seam, without dismounting back end cover for motor, can realize assembling and the replacing of resolver or connecting axle.This has not only guaranteed the assembly precision of rear bearing and bearing of rear end cover chamber, has also improved motor reliability of operation.The utility model not only can guarantee the stator of resolver and the height of rotor when work concentric, make the long-time accurately feedback signal of resolver, guarantee that direct driving motor normally moves, be also convenient to the installation of resolver.
