Abstract
The present invention relates to gear-box field, in particular to a kind of gear-box oil-returning structure for improving oily filter installation site.The gear-box oil-returning structure includes the oil return line (1) of connection cavity (2), oily filter (3) are installed in oil return line (1), the strainer (31) of oily filter (3) is the cylindrical body of one end end face opening, towards the outlet of oil return line (1), strainer (31) is interior from opening direction to cavity (2) to be extended for the open end of strainer (31).One kind is provided in existing structure and space, and under the premise of easy disassembly, the structure type that strainer holds dirty ability, gear-box overtemperature significant trouble caused by avoiding because of filter net jam can be improved.
Description
Technical field
The present invention relates to gear-box field, in particular to a kind of gear-box oil-returning structure for improving oily filter installation site.
Background technique
Lubricating oil in uni-drive gear box oil system will necessarily be polluted, and main includes the abrasion of friction pair part
And corrosion, lubricating oil coking or greasy filth, sand and dust, the sordid machine of cleaning of external world's entrance add residual etc., therefore, net-filter assembly is to pass
The indispensable components of movable tooth roller box oil system.The strainer used in certain uni-drive gear box is a kind of taper grid-net type filter at present
Net is directly installed in the drain line of gear-box, and such as Fig. 1, structure is simple, convenient for installation and maintenance, can in product normal use
It satisfies the use demand.However, when uni-drive gear box answers some components to be damaged, when generating more metal particle or impurity, filter
Net is easy to happen blocking, causes gear-box lubricating oil oil return unsmooth, lubricating oil accumulates in gear cavity.In high-speed gear Stirring
Under, intracavitary oil temperature sharply increases, and gear-box entirety overtemperature causes great secondary failure.
Summary of the invention
Present invention solves the technical problem that: one kind is provided in existing structure and space, and under the premise of easy disassembly, can be changed
Kind strainer holds the structure type of dirty ability, gear-box overtemperature significant trouble caused by avoiding because of filter net jam.
Technical solution of the present invention: a kind of gear-box oil-returning structure, the gear-box oil-returning structure include connection cavity
Oil return line, oily filter is equipped in oil return line, and the strainer of oily filter is the cylindrical body of one end end face opening, the open end court of strainer
Outlet to oil return line, strainer extend from opening direction into cavity.
Preferably, gap is provided between the outer circumference surface of strainer and the inner wall of cavity.It can guarantee the smooth installation of strainer,
The circulation area of strainer is not influenced, and promotes the dirty ability of appearance.
Preferably, the oily filter further includes skeleton, and strainer is coated on skeleton periphery.Increasing skeleton structure can be improved strainer
Intensity, increase the length of strainer.The circulation area of strainer can significantly be promoted and hold dirty ability.
Detailed description of the invention
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is schematic structural view of the invention；
Fig. 3 is oily filter structural schematic diagram.
In figure: 1-32-skeleton of oil return line 2-cavity, 3-oily filter, 4-shell, 31-strainer 33-
34-overflow hole of side is installed
Specific embodiment
As shown in Figure 1, prior art construction assembles oily filter 3 in oil return line 1, which can be convenient tearing open for oily filter
It unloads and cleans.But due to the influence in space in oil return line, the length and diameter of strainer 31 can be all extremely limited, by
Limitation in space, oily filter 3 are difficult to increase skeleton structure, for the intensity for guaranteeing oily filter 3, strainer 31 can only be designed as taper knot
Structure, caused circulation area are smaller.When wearing and damaging occur in part inside uni-drive gear box, the metal fragment fallen is all
Understand and accumulated with lubricating oil to oil return opening position, it is easy to oil return line 1, oily filter 3 be filled up into covering, lead to the oil return of gear-box not
Freely.Lead to the 2 accumulated inside lubricating oil of cavity in shell 4, be brought rapidly up under the agitation of rotating part in gear-box, is caused entire
The damage of product overtemperature, causes great secondary failure.
As shown in Fig. 2, in the technical program, by oily filter 3 by being adjusted in cavity 2 in oil return line 1, to protect
The convenient disassembly of strainer is demonstrate,proved, assembly direction assembles from outside to inside.
As shown in figure 3, being the appearance dirt ability of promotion oily filter 3 big as far as possible, the space of cavity 2 is made full use of in this programme,
Oily filter 3 is designed as cylindrical structure.Improved oily filter is made of strainer 31 and skeleton 32, and 31 clad welded of strainer is in skeleton 32
Cylindrical surface on, the diameter of oily filter 3 is determined by the distance of installation bore dia and 2 side wall of cavity, with guarantee oily filter installation and with
The gap of the inner wall of cavity.Skeleton 32 is used for axially position with installation side 33.The length of skeleton 32 is according to the space of cavity 2
Design is grown as far as possible, and skeleton cylindrical surface and end face are provided with overflow hole 34, guarantee the circulation area of lubricating oil.
The technical program makes full use of the space of cavity 2 to promote oily filter on the basis of not changing existing structure correlated parts
Appearance dirt ability, achieve the purpose that prevent oily filter from blocking.
