Abstract
The utility model provides a kind of hydraulic pressure oil distribution casing, and its structure is simple, can effectively avoid oil distributing shaft or join the problem of oil pocket wearing and tearing, extend working life; It comprises oil distribution casing body, and described oil distribution casing body central has axis hole, and described shaft hole inner wall side face is interval with the groove of circular arc, and axle sleeve is loaded in described axis hole, and the axle sleeve of corresponding described groove is provided with outstanding projection.
Description
Technical field
The utility model relates to technical field of hydraulic elements, is specially a kind of hydraulic pressure oil distribution casing.
background techniqueexisting oil hydraulic motor often adopts axial flow distribution in distributing construction, and its structure is simple, is convenient to realize, but once oil distributing shaft or join oil pocket wearing and tearing, gap cannot compensate, and internal leakage increases, and reduces motor plot ratio, affects working life.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hydraulic pressure oil distribution casing, and its structure is simple, can effectively avoid oil distributing shaft or join the problem of oil pocket wearing and tearing, extend working life.
Its technological scheme is such: it comprises oil distribution casing body, it is characterized in that: described oil distribution casing body central has axis hole, described shaft hole inner wall side face is interval with the groove of circular arc, and axle sleeve is loaded in described axis hole, and the axle sleeve of corresponding described groove is provided with outstanding projection.
It is further characterized in that: the number of described groove, projection is all no less than two.
The beneficial effects of the utility model are, oil distribution casing body upper shaft hole inwall side face is interval with the groove of circular arc, axle sleeve is loaded in axis hole, then when oil distribution casing body and oil distributing shaft routing motion, axle sleeve in axis hole effectively can prevent the wearing and tearing of oil distributing shaft, also only need by axle sleeve dismounting and change once wearing and tearing are bad, the axle sleeve of respective slot is provided with outstanding projection, axle sleeve is secured in the groove of axis hole by projection, avoid in movement process, axle sleeve comes off, thus extends working life, reduces cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises oil distribution casing body 1, oil distribution casing body 1 center has axis hole 2, axis hole 2 inwall side face is interval with the groove 3 of circular arc, axle sleeve 4 is loaded in axis hole 2, then, when oil distribution casing body 1 and oil distributing shaft routing motion, the axle sleeve 4 in axis hole 2 effectively can prevent the wearing and tearing of oil distributing shaft, also only need by axle sleeve 4 dismounting and change once wearing and tearing are bad, the axle sleeve 4 of respective slot 3 is provided with outstanding projection 5; The number of groove 3, projection 5 is all no less than two, and axle sleeve 4 is secured in the groove 3 of axis hole 2 by projection 5, avoids in movement process, and axle sleeve 4 comes off, thus extends working life, reduces cost.
