Utility model content
Technical problem to be solved in the utility model is to provide one can overcome above-mentioned defect, improves the diesel locomotive air compressor machine power input structure of fail safe and installing/dismounting efficiency.
The utility model solves the technical scheme that its technical problem adopts: diesel locomotive air compressor machine power input structure, comprise motor and air compressor machine, and described motor comprises housing, rotor and stator, stator is fixedly installed in inner walls; Described air compressor machine is provided with air compressor machine driving shaft; In described motor, be provided with motor output shaft, rotor is fixedly mounted on motor output shaft, and motor output shaft is connected by spring coupling with air compressor machine driving shaft.
Further, in described housing, the two ends of motor output shaft are equipped with bearing.
Further, the center, driving end end of described motor output shaft is provided with screwed hole, in spring coupling, the end of motor output shaft outside is provided with shaft end ring, diameter and shaft end ring center that the diameter of shaft end ring is greater than motor output shaft place axis hole are provided with the centre bore consistent with screwed hole openings of sizes, shaft end ring is fixed on motor output shaft driving end outside by passing centre bore and forming with screwed hole the screw being threaded, and screw head is resisted against air compressor machine driveshaft end.
The beneficial effects of the utility model are: by setting up motor output shaft and use after spring coupling is in transmission connection motor output shaft and air compressor machine driving shaft on motor, can in the situation that not affecting air compressor machine operating efficiency, motor and air compressor machine be split as to two relatively independent parts, make air compressor machine in the time breaking down, can not impact and be convenient to dismounting to motor, improved fail safe and the overhaul efficiency of whole power input structure.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 2 to 4, diesel locomotive air compressor machine power input structure of the present utility model, comprises motor 1 and air compressor machine 2, and described motor 1 comprises housing 11, rotor 12 and stator 13, and stator 13 is fixedly installed on housing 11 inwalls; Described air compressor machine 2 is provided with air compressor machine driving shaft 21; In described motor 1, be provided with motor output shaft 14, rotor 12 is fixedly mounted on motor output shaft 14, and motor output shaft 14 is connected by spring coupling 3 with air compressor machine driving shaft 21.After motor output shaft 14 is set and by spring coupling 3, motor output shaft 14 and air compressor machine driving shaft 21 is coupled together, air compressor machine 2 and motor 1 in whole power input structure are separated the parts relatively independent for two; When work, motor 1 is the mechanical energy of motor output shaft 14 by electric energy conversion by the electromagnetic action between rotor 12 and stator 13, motor output shaft 14 transfers a torque to air compressor machine driving shaft 21 by spring coupling 3, thereby realizes the power input to air compressor machine 2.Compared to prior art, on air compressor machine driving shaft 21 in the utility model, directly do not stretch into the power output shaft of motor 1 inside as motor, eliminate thus because the factors such as diesel locomotive vibration cause air compressor machine 2 to deform with air compressor machine driving shaft 21 or cause when fault and in motor 1, occurred rotor 12 stators 13 potential safety hazard such as wiping mutually, and avoided need removing motor in the time that air compressor machine is carried out to field-strip, that has improved diesel locomotive air compressor machine power input structure removes and installs efficiency and overall security. simultaneously
As shown in Figure 3, on the basis of above-mentioned execution mode, for the stability of increasing combustion engine car air compressor machine power input structure, the two ends of the interior motor output shaft 14 of described housing 11 are equipped with bearing 15.The effect of bearing 15 is that motor output shaft 14 is supported and be fixed on motor 1 center, vibrate the radial stress producing and the radial displacement that may therefore cause can play an important role for eliminating motor output shaft 14 because of diesel locomotive, may cause various motor 1 faults, the reliability and the fail safe that have improved motor 1 because of motor output shaft 14 radial displacements thereby effectively taken precautions against.
As shown in Figure 4 and Figure 5, as preferably, the center, driving end end of described motor output shaft 14 is provided with screwed hole 4, in spring coupling 3, outside, the driving end end of motor output shaft 14 is provided with shaft end ring 5, diameter and shaft end ring 5 centers that the diameter of shaft end ring 5 is greater than motor output shaft 14 place axis holes are provided with the centre bore consistent with screwed hole openings of sizes 51, shaft end ring 5 is fixed on motor output shaft 14 outsides, driving end ends by passing centre bore 51 and forming with screwed hole 4 screw 6 being threaded, and screw 6 head abuts are in air compressor machine driving shaft 21 ends.Shaft end ring 5 is fixed on rear flank outside the driving end end of motor output shaft 14 by screw 6, because its diameter is greater than the diameter of motor output shaft 14 place axis holes and screw 6 head abuts in air compressor machine driving shaft 21 ends, therefore shaft end ring 5 can be fixed motor output shaft 14 in the axial direction, thereby eliminate moving axially phenomenon and having avoided the fault that may bring thus of motor output shaft 14, further improved stability and the fail safe of diesel locomotive air compressor machine power input structure.
