Description
Technical field
The utility model relates to a kind of motor component, relates in particular to a kind of high-speed pulling motor rotating shaft.
Background technique
Traction electric machine refers to the upper motor for drawing of trunk railway electric locomotive, industrial and mineral electric locomotive, diesel electric locomotive and various electric vehicle (as battery car, city electric car, underground railway electric vehicle).At locomotive operation, to bear sizable impact shock during by rail gap and track switch; During large and small poor gear engagement, on armature, can produce strong torsional vibration; In rugged environment, use, rain, snow, the easy intrusion of dust and sand etc., therefore traction electric machine also has many requirements in design and structure, make full use of internal body space and make compact structure, adopt higher insulating material and permeability magnetic material, component need have higher mechanical strength and rigidity, and whole motor need have good ventilation and heat condition and dust and moisture ability, take special measure to deal with more difficult " commutation " condition to reduce spark under carbon brush etc.The design of traction electric machine need to meet above-mentioned conditional request, and this just makes the design of machine shaft also exist many difficulties.Machine shaft of the prior art, in order to meet its requirement of strength, it is comparatively complicated that structure often designs, and the processing technique of getting up is loaded down with trivial details, and volume is larger; And if comparatively brief by rotating shaft design has its structural strength often to impact, and between motor driving part part, the part of transmitting torque usually occurs damaging and causes scrapping of machine shaft.
Model utility content
The technical problems to be solved in the utility model is to provide and a kind ofly not only can meets requirement of strength, and simple in structure, and processing technology is easy, the high-speed pulling motor rotating shaft of small volume.
For addressing the above problem, a kind of high-speed pulling motor rotating shaft of the present utility model, comprises the shaft part one, shaft part two, shaft part three, the shaft part four that set gradually from left to right; Described shaft part one middle part is provided with necking down structure; Described shaft part two middle parts are provided with the shaft shoulder, and in the left side of described shaft part two, upper and lower symmetry offers two the first keyways, on the right side of described shaft part two, offers second keyway; The right-hand member of described shaft part three offers radial direction through hole; Described shaft part four comprises the circular shaft section in left side and positive six prisms on right side, and these positive six prism cross section circumscribed circle diameters are identical with the round shaft section diameter of shaft part four.
The length of described shaft part one, shaft part two, shaft part three, shaft part four is respectively 50.5cm, 64.6cm, 51.8cm, 31cm.
In described shaft part four, the length of positive six prisms is 16cm.
Described necking down locations of structures diameter is 7cm, and being positioned at necking down structure two side position diameters is 8cm.
In described shaft part two, shaft shoulder left part diameter is 20cm, and shaft shoulder right side section diameter is 13cm.
Described shaft part three diameters are 14cm, and through-hole diameter is 6cm.
Described positive six prism cross section inscribed circle diameters are 10cm.
Engine fuel system coupling shaft of the present utility model, by be respectively arranged with the first keyway on shaft part two, contact for transmitting torque with motor driving part part with the second keyway simultaneously, reach good moment of torsion transmission effect, avoid the stressed excessive keyway edge fracture that causes of single keyway; By positive six prisms and driven member, peg graft, install more for convenience, moment of torsion transmission effect is good simultaneously; Coupling shaft overall structure arranges simply simultaneously, and processing technology is more convenient, and small volume is convenient to installation and removal.
