Abstract
The utility model relates to an improved vibration-damping shock-resisting device for the mounting screws of a gear cover of a pulling motor of a DF4B type internal combustion locomotive. The utility model is composed of an outer sleeve and a vibration-damping ring, wherein, the outer sleeve is composed of an outer sleeve body, an outer sleeve cavity and an outer sleeve hole; the vibration-damping ring is composed of a rubber body and a vibration-damping cavity; the rubber body is a hollow cylinder; the vibration-damping ring is positioned in the outer sleeve cavity. The utility model can reduce gear vibration generated when a locomotive runs in high speed; the utility model has shock resistance, and ensures that the mounting screws are not loosened.
Description
The utility model relates to the anti-buffering apparatus of vibration damping that a kind of improved DF4B type locomotive traction electric machine gear cover is installed screw.Belong to diesel locomotive shock attenuation unit field in the mechanical industry.
Existing gear cover is installed screw and is adopted common spring chair or adopt the swollen screw that rises anti-slow.Because behind the train speed raising, locomotive is turned and interface by rail, the longitudinal impact that laterally reaches that is subjected to all obviously strengthens, and causes the gear cover fault frequent.Owing to casing rigidity deficiency, effectiveness in vibration suppression is bad, easily snaps, tears, is out of shape after the power that is hit on the one hand; On the other hand, because gear cover is installed screw, limited by operating condition, anti-slow auto-lock function is poor.It is that one of railway interests is outstanding that gear cover breakage, screw are lost, and the frequent fault that takes place.
The purpose of this utility model provides a kind of gear vibration that can reduce the generation of locomotive high-speed cruising, and shock resistance guarantees to install the tight gear cover of screw the anti-buffering apparatus of screw vibration damping is installed.
The anti-buffering apparatus of the utility model vibration damping is to be made of overcoat and shock ring, and overcoat is to be made of outer sleeve body, mantle cavity and external trepanning, and shock ring is to be made of rubber bodies and vibration damping chamber, and rubber bodies is the cylinder of hollow, and shock ring is positioned at mantle cavity.
Using method: will be existing gear cover install and install vibration damping additional between screw and the traction electric machine hanger (mounting teeth wheel cover seat) and prevent buffering apparatus, screw is passed the external trepanning of overcoat successively and the vibration damping chamber of shock ring is fixed on the traction electric machine hanger.The rubber bodies close fit is in outer sleeve body, and under the effect of screw fastening force, rubber is subjected to force compresses to produce distortion, because the restriction of outer sleeve body, rubber can only shrink to the inside, clamps screw is installed.The end face and the traction electric machine hanger of rubber bodies are tightly closely connected simultaneously, because the friction coefficient of rubber and iron is higher than the friction coefficient of iron and iron far away.Therefore, screw is installed, vibration damping prevents that buffering apparatus, hanger, gear cover almost become one.Rubber bodies has all absorbed and has come from the high-frequency vibration of wheel to transmitting by the traction electric machine hanger.Thereby guaranteed the gear cover screw not loose, do not lose.
The gear cover that the utility model provides is installed the anti-buffering apparatus of screw vibration damping, can reduce the gear vibration that the locomotive high-speed cruising produces, shock resistance, and it is not loosening to guarantee to install screw.
Below with reference to accompanying drawing the anti-buffering apparatus of vibration damping is described in detail.
Fig. 1 is the anti-buffering apparatus scheme drawing of vibration damping
Fig. 2 is the overcoat section-drawing of the anti-buffering apparatus of vibration damping
Fig. 3 is the overcoat birds-eye view of the anti-buffering apparatus of vibration damping
Fig. 4 is the shock ring section-drawing of the anti-buffering apparatus of vibration damping
Fig. 5 is the attached view of shock ring of the anti-buffering apparatus of vibration damping
The anti-buffering apparatus of the utility model vibration damping is to be made of overcoat 2 and shock ring 1, overcoat 2 is to be made of outer sleeve body 3, mantle cavity 4 and external trepanning 5, shock ring 1 is to be made of rubber bodies 6 and vibration damping chamber 7, and rubber bodies 6 is the cylinder of hollow, and shock ring 1 is positioned at mantle cavity 4.
Using method: will be existing gear cover install and install vibration damping additional between screw and the traction electric machine hanger (mounting teeth wheel cover seat) and prevent buffering apparatus, screw is passed the external trepanning 5 of overcoat 2 successively and the vibration damping chamber 7 of shock ring 1 is fixed on the traction electric machine hanger.Rubber bodies 6 close fits are in outer sleeve body 3, and under the effect of screw fastening force, rubber is subjected to force compresses to produce distortion, because the restriction of outer sleeve body 3, rubber can only shrink to the inside, clamps screw is installed.The end face and the traction electric machine hanger of rubber bodies 6 are tightly closely connected simultaneously, because the friction coefficient of rubber and iron is higher than the friction coefficient of iron and iron far away.Therefore, screw is installed, vibration damping prevents that buffering apparatus, hanger, gear cover almost become one.Rubber bodies 6 has all absorbed and has come from the high-frequency vibration of wheel to transmitting by the traction electric machine hanger.Thereby guaranteed the gear cover screw not loose, do not lose.
