Which comprises a pump body, install rotatable oil pump drive spindle in the pump body, the end cover is installed to a side of the pump body the end cover with install first sealing member between the oil pump drive spindle, the transversal U type of personally submitting of first sealing member, on the oil pump drive spindle, for the second sealing member is installed to the one end of end cover. The utility model discloses an install the sealing member between the terminal surface of oil pump drive spindle and end cover, can make sealed effect better, reduce the quantity of vulnerable part, practice thrift the cost.
Description
Technical field
The utility model relates to a kind of sealing configuration for compressor oil pump drive shaft, belongs to mechanical equipment technical field.
Background technique
In the prior art, in order to prevent oil pump from occurring leakage of oil situation at work, usually seal ring can be increased between rotor and supporting mechanism for location thereof; but; when rotor after a long-term service, easily make ring wear, so cause oil pump occur leak oil condition.
Model utility content
For solving the problem, the utility model provides a kind of structure simple, easy to use for oil pump transmission axle sealing structure.
The technological scheme that the utility model adopts for its problem of solution is:
A kind of sealing configuration for compressor oil pump drive shaft, comprise the pump housing, be provided with rotating oil pump drive spindle in the described pump housing, a side of the pump housing is provided with end cap, between described end cap and described oil pump drive spindle, be provided with the first Sealing, the cross section of described first Sealing is U-shaped; On described oil pump drive spindle, relative to one end of described end cap, the second Sealing is installed.
Preferably, the inner one end near the second Sealing of described oil pump drive spindle is provided with cavity.
Preferably, described first Sealing comprises the first sealed department abutted with the inner side surface of end cap, and the second sealed department abutted with the outer side wall of described oil pump drive spindle.
Preferably, described second sealed department is provided with to the outstanding lip part in described oil pump drive spindle side.
Preferably, the 3rd Sealing is installed between described end cap and the described pump housing.
Preferably, described oil pump drive spindle is provided with the circular groove for installing described second Sealing.
The beneficial effects of the utility model are: by installing Sealing between the end face and end cap of oil pump drive spindle, sealing effect can be made better, reduce the quantity of easily damaged parts, cost-saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram in A portion in Fig. 1;
Fig. 3 is the enlarged diagram in B portion in Fig. 1.
In figure: 1, the pump housing; 2, oil pump drive spindle; 21, cavity; 3, end cap; 4, the first Sealing; 41, the first sealed department; 42, the second sealed department; 43, lip part; 5, the second Sealing; 6, circular groove; 7, the 3rd Sealing.
Embodiment
A kind of sealing configuration for compressor oil pump drive shaft as shown in accompanying drawing 1 to 3, comprise the pump housing 1, in the described pump housing 1, rotating oil pump drive spindle 2 is installed, one side of the pump housing 1 is provided with end cap 3, between described end cap 3 and described oil pump drive spindle 2, be provided with the first Sealing 4, the cross section of described first Sealing 4 is U-shaped.Described first Sealing 4 comprises the first sealed department 41 abutted with the inner side surface of end cap 3, and the second sealed department 42 to abut with the outer side wall of described oil pump drive spindle 2, when the first Sealing 4 is arranged on after between end cap 3 and oil pump drive spindle 2, deformation can be there is in the first Sealing 4 by compressing, produce elastic restoring force, thus make the first sealed department 41 and the second sealed department 42 compress end cap 3 and oil pump drive spindle 2 respectively, ensure sealing.Further, described second sealed department 42 is provided with to the outstanding lip part 43 in described oil pump drive spindle 2 side, this lip part 43 is tapered, like this, after being there is deformation by compressing in the first Sealing 4, also can ensure that the second sealed department 42 contacts with effective between oil pump drive spindle 2, ensure sealing.
On described oil pump drive spindle 2, relative to one end of described end cap 3, the second Sealing 5 is installed.The inner one end near the second Sealing 5 of described oil pump drive spindle 2 is provided with cavity 21, and to carry out fuel feeding to bent axle, after oil pump drive spindle 2 with crankshaft installed, the second Sealing 5 can to the sealing gap between oil pump drive spindle 2 and bent axle.Described oil pump drive spindle 2 is provided with the circular groove 6 for installing described second Sealing 5, and when making oil pump drive spindle 2 and crankshaft installed, the second Sealing 5 can not be shifted.
3rd Sealing 7 is also installed, to ensure the sealing in the gap between end cap 3 and the pump housing 1 between described end cap 3 and the described pump housing 1.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
