Abstract
The invention relates to a rolling mill speed reducer for reducing oil leaks, which comprises a reducer box, an oil receiving pan fixedly connected with the box, a bearing bush supported on the box and a bearing installed in the bearing bush. The bearing is fixedly connected with a shaft shoulder of an output shaft, a distance ring is tightly attached to an inner ring of the bearing, and a lock nut screwed into the output shaft is arranged outside the distance ring. The speed reducer is characterized in that the box is fixedly connected with the oil receiving pan, the center of the oil receiving pan is provided with a central hole for the shaft head to pass through, and the periphery of the central hole is provided with cylindrical circular protrusions. The invention has the advantages that a sealing device of the output shaft end of the rolling mill speed reducer is changed, the oil receiving pan is additionally installed outside an end cover, and meanwhile, oil injected into the reducer box and used for lubricating the bearing is blocked by a labyrinth sealing oil path formed by two sheathed protrusions and guided into the oil receiving pan to be discharged out of the reducer box.
Description
Technical field
The invention belongs to reductor, relate in particular to a kind of rolling mill speed reducer that reduces leakage of oil.
Background technology
The sealing device of the decelerator output that milling train is used adopts the magnetic seal mode mostly, and its price is higher; The sealing of employing sealing ring, sealing ring are aging, poorly sealed easily, leakage of oil occurs.Usually design is the design concept of taking " blocking up " substantially, oil is blocked as far as possible, and still, the actual conditions leakage of oil is still very serious, and always stream oil is continuous around ground and the equipment.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of rolling mill speed reducer that reduces leakage of oil is provided, change the sealing device of milling train speed reducer output shaft end, add the attaching food tray, the oil of lubricating bearings in the injection reduction box is converged to discharge reduction box in the oil drain pan at end cap.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of rolling mill speed reducer that reduces leakage of oil, comprise deceleration box, with the affixed oil drain pan of casing, be bearing in the casing upper bearing sleeve, bearing is housed in the bearing holder (housing, cover), the bearing and the output shaft shaft shoulder are affixed, the inner ring of bearing is glued with spacer ring, the spacer ring outside is provided with the locking nut that is spirally connected with output shaft, it is characterized in that: be connected with oil drain pan on the described casing, described oil drain pan center is provided with the centre bore that spindle nose passes through, and the centre bore periphery is provided with the cylindrical annular projection.
Described spacer ring cylindrical circumferential surface is welded with annular and gets rid of oily wing.
The female outside of described locking end face is provided with the cylindrical annular projection, and the internal radius of described projection is greater than the cylindrical annular projection diameter of oil drain pan centre bore periphery.
Beneficial effect: change the sealing device of milling train speed reducer output shaft end, utilization
" mode adds the attaching food tray at end cap to a kind of apple, and the protruding formed labyrinth seal oil circuit of the oil that will inject lubricating bearings in the reduction box simultaneously by two sockets intercepts and direct into discharges reduction box in the oil drain pan.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of the I of Fig. 1.
The specific embodiment
Below in conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention: see accompanying drawing for details, a kind of rolling mill speed reducer that reduces leakage of oil, comprise deceleration box 4, the affixed end cap 6 of bearing holder (housing, cover), be bearing in casing upper bearing sleeve 5, bearing 7 is housed in the bearing holder (housing, cover), the bearing and the output shaft shaft shoulder are affixed, the inner ring of bearing is glued with spacer ring 2, the spacer ring outside is provided with the locking mother 3 who is spirally connected with output shaft, be connected with oil drain pan 1 on the described end cap, described oil drain pan center is provided with the centre bore that spindle nose passes through, and the centre bore periphery is provided with cylindrical annular projection 1-1.Described spacer ring cylindrical circumferential surface welding annular is got rid of oily wing 2-1, forms speed difference, strengthens oil-throwing performance.Female 3 outside end faces of described locking are provided with cylindrical annular projection 3-1, the internal radius of described projection is greater than the cylindrical annular projection diameter of oil drain pan centre bore periphery, the cylindrical annular projection of oil drain pan can be packed into one section, form the labyrinth sealing oil circuit, oil is intercepted and direct into the oil drain pan inner chamber.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
