Abrasion, be provided on the inner hole wall surface of axle sleeve and deposit rouge slot for storing butter, to realize between axle sleeve and hinging pin shaft
Lubrication.In the prior art, the rouge slot of depositing on axle sleeve is through slot, that is, deposits rouge slot in the both ends end face of axle sleeve and all have opening,
When in use, it needs that dust-proof seal ring is installed at the both ends of axle sleeve, cooperation dust-proof seal ring uses.But it is some it is miniature on, by
Small in size, sleeve length direction is size-constrained, if cooperating dust-proof seal ring, axle sleeve processing difficulties.
Utility model content
The technical problems to be solved in the utility model be axle sleeve deposit rouge slot both ends open needs be used cooperatively with dust seal
The shortcomings that, and a kind of axle sleeve and articulated structure are provided.
The utility model is to realize that the technical solution of its purpose is such that construct a kind of axle sleeve, is cylindrical in shape, in its inner hole
Wall surface on be provided with left-handed and dextrorotation deposit rouge slot；It is characterized in that it is described deposit rouge slot only one end of the axle sleeve have open
Mouthful.
In above-mentioned axle sleeve, the outer oil sump of the circular ring shape around the axle sleeve is provided on the external cylindrical surface of the axle sleeve,
It is provided with the inner oil sump of the circular ring shape around the axle sleeve on the inner hole wall surface of the axle sleeve, is provided in the outer oil sump multiple
The radial direction oil hole being connected to inner oil sump.
The utility model is to realize that the technical solution of its purpose is such that construct a kind of articulated structure, including first
Part, second component, hinging pin shaft are provided with coaxial hinge hole, the hinging pin shaft on the first component and second component
Sleeve is fixedly connected in the hinge hole of the first component and with the first component, it is characterised in that further includes axis above-mentioned
Set, the axle sleeve is fixedly installed in the hinge hole of the second component, the hinging pin shaft pass through the inner hole of the axle sleeve with
Axle sleeve clearance fit, the axle sleeve between the end and the first component for depositing rouge channel opening be equipped with gasket, two of the gasket
Side is connected with the end face of the first component and axle sleeve respectively.Further, it is provided on the second component and the axis
Oil-way communicates identical grease adding mouth on set.
Compared with prior art, the rouge slot of depositing in axle sleeve is processed into semi-enclosed the utility model, to deposit rouge, is assembling
Shi Buzai needs that dust-proof seal ring is cooperated to use, then sleeve length direction size can increase, ensure that the processable of axle sleeve
Property, after axle sleeve assembly, lubricating grease is overflowed in the open end for depositing rouge slot, and effect can be lubricated to gasket, reduces gasket and axle sleeve
Between abrasion.

Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
As shown in Fig. 1 Fig. 2, the axle sleeve 1 in the present embodiment is cylindrical in shape, be provided on the wall surface of its inner hole it is a plurality of it is left-handed and
Rouge slot 11 is deposited in dextrorotation, the outer oil sump 12 of the circular ring shape around the axle sleeve is provided on the external cylindrical surface of axle sleeve 1, in axle sleeve
Inner hole wall surface on be provided with the inner oil sump 13 of circular ring shape around the axle sleeve, be provided in outer oil sump and multiple connect with inner oil sump
Logical radial direction oil hole 14.Depositing rouge slot only has opening in one end of axle sleeve, and the other end is then closed, that is, deposits one end of rouge slot as opening
End 15, open end is located on the end face of axle sleeve one end, deposit rouge slot the other end be closed end 16, in closed end this deposit rouge slot with separately
It deposits rouge slot for outer one to communicate, on axle sleeve, deposits the closed end of rouge slot and be not extend to the end face of axle sleeve.
Above-mentioned axle sleeve is applied to linkwork, and as shown in Fig. 3 Fig. 4, bracket 2 is used as second component, with what is be parallel to each other
