Abstract

The utility model discloses an oil throwing device applied to a rolling mill. The oil throwing device applied to the rolling mill comprises an input shaft and a sealing subassembly, wherein the sealing subassembly is arranged on the input shaft; an oil throwing plate is arranged above the sealing subassembly; an oil returning box is arranged below the sealing subassembly; the sealing subassembly comprises a through cover and a lip-shaped rotary seal; the through cover surrounds the input shaft; the lip-shaped rotary seal is arranged above the through cover and clings to the input shaft; the oil throwing plate comprises an oil throwing plate main body, an oil throwing plate inner hole and a conical surface; the oil throwing plate inner hole is formed in the middle of the oil throwing plate main body; the input shaft is clamped in the oil throwing plate inner hole; and the conical surface is arranged on two sides of the oil throwing plate inner hole. The oil throwing plate is additionally arranged at an end of the input shaft; the upper surface of the oil throwing plate is the conical surface; and the inner hole is in interference fit with the shaft, so that lubricating oil is distributed and shielded. The oil throwing device applied to the rolling mill is simple in structure and high in practicality. The problem that the lubricating oil leaks from the end of the input shaft when the rolling mill normally works or stops in a vertical state is fundamentally solved.

Description

A kind of oil thrower that is applied to milling train

Technical field

The utility model relates to the oil-sealing arrangement of milling train, is specifically related to a kind of oil thrower that is applied to milling train, specifically prevents that the lubricant oil of box house from flowing out along input shaft, guarantees lubricant oil Rapid Flow oiler pipeline.

Background technique

The oil thrower of existing milling train, mainly comprises oil return box, transparent cover, and input shaft, lip reinforced seal, and often milling train is stood upside down and placed, box house is to gear, and the lubricant oil of bearing etc. all first flows into this oil return box, from return opening, flows to rare station.

This mill milling speed is slow, therefore input speed is low, can not be special good at the lip rotating seal of input end play seal action.Also have lubricating point many, recirculating oil quantity is large, lubricant oil is saved bit by bit in the bottom of oil return box, make input shaft seal device part be immersed in for a long time lubricant oil the inside, lubricant oil flows down along input shaft, when particularly milling train is just out of service, has very a part of lubricant oil directly to flow out along input shaft, therefore this seal arrangement there will be Seepage, makes troubles to produced on-site.Therefore need a kind of device of novel practical, change this oil return sealing configuration.

Model utility content

The technical problems to be solved in the utility model is to provide a kind of oil thrower that is applied to milling train, at input shaft end, set up a kind of disc, the upper surface of disc own is the conical surface, endoporus and axle interference fit, the shunting of realization to lubricant oil and blocking, this device simple structure, practical, when fundamentally having solved this milling train in the normal work of vertical state and having suspended, the phenomenon that input shaft end has lubricant oil to leak outside.

For achieving the above object, the technical solution of the utility model is as follows:

An oil thrower that is applied to milling train, comprising:

One input shaft,

One is arranged at the black box on input shaft, and described black box top arranges a disc, and black box below arranges an oil return box,

Described black box comprises that one is surrounded on the transparent cover of input shaft, and one is arranged at transparent cover top and fits tightly the lip rotary seal of input shaft.

In a preferred embodiment of the present utility model, described disc comprises:

One disc main body,

One is arranged at the disc endoporus of the clamping input shaft at disc main body middle part,

An and conical surface that is arranged at disc endoporus both sides.

In a preferred embodiment of the present utility model, described disc endoporus top arranges an inverted trapezoidal shape.

In a preferred embodiment of the present utility model, the length of the described conical surface is less than the length of oil return box.

By technique scheme, the beneficial effects of the utility model are:

The structure of the utility model by the special conical surface of disc, with the reasonable coordination of between centers and axial suitable installation, guaranteeing, under the prerequisite of the normal operation of milling train, to make input end oil return smooth and easy, simultaneously the non lubricant oil phenomenon that leaks outside.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of disc of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

With reference to Fig. 1, shown in Fig. 2, a kind of oil thrower that is applied to milling train, comprising:

One input shaft 100,

One is arranged at the black box 200 on input shaft 100, and described black box 200 tops arrange a disc 300, and black box 200 belows arrange an oil return box 400,

Described black box 200 comprises that a transparent cover 201, that is surrounded on input shaft is arranged at transparent cover 201 tops and fits tightly the lip rotary seal 202 of input shaft.

Described disc 300 comprises: a disc main body 301, one is arranged at the disc endoporus 302 of the clamping input shaft 100 at disc main body middle part, an and conical surface 303 that is arranged at disc endoporus 302 both sides, these disc endoporus 302 tops arrange an inverted trapezoidal shape, and the length of this conical surface 303 is less than the length of oil return box 400.

Disc is arranged on input shaft, between disc endoporus and input shaft, adopts slight interference amount to be connected, and guarantees that disc and input shaft together rotate, and lubricant oil cannot flow down by direct-axis.

When milling train normally moves, input shaft and lip rotary seal relative movement produce pressure difference, form rotary seal;

The lubricant oil flowing down along input shaft is in a large number fallen on the disc conical surface, and make centrifugal motion, lubricant oil is dispersed to oil box bi-side, directly by return tube, flows out; Ultimate return tube is in oil return box lower right corner minimum point, and all lubricant oil of milling train all flows out by this oil return box;

When milling train just quits work, a large amount of lubricant oil can, under disc conical flow, block the lubricant oil flowing down with forward position input shaft.

No matter the normal work of milling train still suspends, and has all well formed effective lubricant oil shunting and has sealed reliably.

More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
