Abstract

The utility model relates to a foundry-ladle double-worm inclined-rotation speed reducer, which comprises a case body, a worm wheel shaft, a big worm wheel, a big worm, packing ears, a suspension rod, a protective cover, a small worm wheel installed at one end of the big worm, a small worm and a control handwheel. The utility model has the advantages that the structure is simple, the cost is reduced, the flexibility and the smoothness of the inclined-rotation of a foundry ladle are not affected by temperature, the transmission precision is high, a deadlocking phenomenon generated by transmission is avoided and the influence of thermal expansion is eliminated. The utility model can be used in casting industries.

Description

The ladle twin worm retarder that verts

Under technical field the present invention relates to a kind of ladle twin worm retarder that verts, can be widely used in the casting industry.

The existing ladle inclining rotary mechanism of background technique, flexibility, the stationarity of verting are poor, easy temperature influence, complex structure, the cost height can produce stuck phenomenon.

Flexibility that summary of the invention the object of the present invention is to provide that a kind of simple in structure, cost reduces, ladle is verted and stationarity be temperature influence, transmission accuracy height, the ladle twin worm that avoids transmission to produce stuck phenomenon, the elimination thermal expansion influence retarder that verts not.

In order to achieve the above object, the ladle twin worm of the present invention retarder that verts, comprise the casing that has the card fork, be installed in the worm-wheel shaft on the casing, the big worm gear of on worm-wheel shaft, installing, big worm screw with big worm gear engagement, be installed in the bag ear on ladle of being used for fixing on worm-wheel shaft one end, between casing and Bao Er, be installed on the worm-wheel shaft and the suspension rod by casing card fork location, be installed in the protective housing on the suspension rod, at the small gear of big worm screw one end installation, with the small worm of small gear engagement, at the bag hand wheel that inclines of small worm overhanging end installation.

The ladle twin worm of the present invention retarder that verts, the big worm screw of big worm gear being installed in the casing and being engaged with, worm-wheel shaft one end is fixed by Bao Er and ladle, and be connected with suspension rod by bearing, at an end of big worm shaft, small gear has been installed, the small worm overhanging end that is engaged with is equipped with the bag hand wheel that inclines, casing has card fork and suspension rod location, and whole retarder is supported on the worm-wheel shaft.

The ladle twin worm of the present invention retarder that verts, its working principle is: when ladle was in suspended state, suspension rod then was fixed on the vertical position; When inclining bag, rotate the handwheel input torque, drive big worm screw through small worm, small gear and rotate, and promote big worm gear rotation, big worm gear drives worm-wheel shaft rotates, give the bag ear with transmission of torque, at this moment casing is fixed with suspension rod through the card fork, and suspension rod is at suspended state, under its load action of gravity, be in plumbness, no moment of face can not rotate, and can only be that ladle is rotated under worm-wheel shaft drives; If the backward rotation handwheel, then the ladle direction of verting is opposite.

The ladle twin worm of the present invention retarder that verts, component are few, and are simple in structure, easy to manufacture, and cost is low.

The ladle twin worm of the present invention retarder that verts, when ladle splendid attire molten iron is poured into a mould, retarder is in the hot environment, when the axis of worm-wheel shaft extends because of thermal expansion, axially not interrupted, the part on it does not produce axial stress, guarantees transmission flexibly under different temperatures, the flexibility that ladle is verted, stationarity are not subjected to Temperature Influence, the transmission accuracy height.

The ladle twin worm of the present invention retarder that verts, when ladle was verted, when molten iron splashed down, because the covering of protective housing, molten iron can not enter in the space between Bao Er and the bearing cap, avoids transmission to produce stuck phenomenon.

The ladle twin worm of the present invention retarder that verts, reducing gearbox adopt card fork structure and suspension rod location, and the whole worm-wheel shaft cantilever support of passing through of retarder has reduced the installation precision requirement, has eliminated and has used bolted Installation Stress, has also eliminated the influence of thermal expansion.

In sum, the ladle twin worm of the present invention retarder that verts, simple in structure, cost reduces, the ladle not temperature influence of flexibility and stationarity that verts, the transmission accuracy height avoids transmission to produce stuck phenomenon, the elimination thermal expansion influence.

Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the A-A sectional view among Fig. 1;

Fig. 3 is the B-B sectional view among Fig. 2.

Embodiment is in Fig. 1～Fig. 3, the ladle twin worm of the present invention retarder that verts, comprise the casing 1 that has card fork a, be installed in the worm-wheel shaft 2 on the casing 1, the big worm gear of on worm-wheel shaft 2, installing 3, big worm screw 4 with big worm gear 3 engagements, be installed in the bag ear 5 on ladle of being used for fixing on worm-wheel shaft 2 one ends, between casing 1 and Bao Er 5, be installed on the worm-wheel shaft 2 and and pitch the suspension rod 6 that a locatees by the casing card, be installed in the protective housing 7 on the suspension rod 6, small gear 8 in that big worm screw 4 one ends are installed with the small worm 9 of small gear 8 engagements, wraps hand wheel 10 at inclining of small worm 9 overhanging ends installation.

Claims

1. ladle twin worm retarder that verts, it is characterized in that, comprise the casing that has the card fork, be installed in the worm-wheel shaft on the casing, the big worm gear of on worm-wheel shaft, installing, big worm screw with big worm gear engagement, be installed in the bag ear on ladle of being used for fixing on worm-wheel shaft one end, between casing and Bao Er, be installed on the worm-wheel shaft and the suspension rod by casing card fork location, be installed in the protective housing on the suspension rod, at the small gear of big worm screw one end installation, with the small worm of small gear engagement, at the bag hand wheel that inclines of small worm overhanging end installation.
