Abstract
The invention discloses a reversing mechanism for an oil pump, and belongs to the technical field of mechanical equipment. The mechanism comprises a pump body in which a rotatable inner rotor is mounted, wherein a positioning supporting block is arranged between the outer side of the inner rotor and the inner side of the pump body in a sleeving manner; an eccentric ring which sleeves the outer side of the inner rotor is arranged between the side surface of the positioning supporting block and the inner side of the pump body; an outer rotor sleeves the outer side of the eccentric ring, and a positioning block is arranged on the side surface of the outer rotor; a positioning pin which is propped to the positioning block is arranged at the inner side of the pump body. The reversing mechanism for the oil pump is simple in structure and can perform the reversing operation without dismounting the oil pump on the premise that the mechanism performances are kept.
Description
Technical field
The present invention relates to a kind of oil pump changement, belong to mechanical equipment technical field.
Background technique
It is immutable that oil pump turns in Fuel injection system, and as input redirect is contrary, then oil pump can not realize oil supply function, and air compressor is damaged.When needs change turn to realize fuel feeding time, need oil pump to take off, artificial commutation is reorientated, then installs.Install more loaded down with trivial details, expend time in.
Summary of the invention
For solving the problem, the invention provides a kind of structure simple, easy to operate oil pump changement.
The technological scheme that the present invention adopts for its problem of solution is:
A kind of oil pump changement, comprise the pump housing, in the described pump housing, rotating internal rotor is installed, positioning support bracer is arranged with between outside described internal rotor and inside the pump housing, between the side of described positioning support bracer and the inner side of the described pump housing, the outside that is positioned at internal rotor is arranged with eccentric hoop, the outside of described eccentric hoop is arranged with external rotor, and the side of described external rotor is provided with positioning block, and the inner side of the described pump housing is provided with the locating stud abutted with described positioning block.
Preferably, filler opening is provided with outside the described pump housing.
Preferably, the outside of the described pump housing is provided with the sealing gland be socketed in outside described internal rotor.
Preferably, the end of described sealing gland is provided with inipple.
Preferably, the inner side of described sealing gland and the outside of described internal rotor are provided with seal ring.
Preferably, the inside of described internal rotor installation transmission shaft is provided with oil circuit.
Preferably, the described pump housing is provided with observation panel.
The invention has the beneficial effects as follows: structure is simple, under the prerequisite of retaining mechanism performance, oil pump can not be dismantled, also can carry out switch operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
In figure: 1, the pump housing; 2, filler opening; 3, internal rotor; 4, positioning support bracer; 5, eccentric hoop; 6, external rotor; 7, positioning block; 8, locating stud; 9, sealing gland; 10, seal ring; 11, oil circuit; 12, observation panel; 13, inipple.
Embodiment
A kind of oil pump changement as shown in Figure 1, comprise the pump housing 1, the filler opening 2 connecting outside oil-feeding device is provided with outside the described pump housing 1, be provided with rotating internal rotor 3 in the pump housing 1, the end of described internal rotor 3 is arranged to square, is directly connected with the bent axle of air compressor, pass through crank-driven, and end is provided with rubber seal, thus reduce the joint gap between bent axle, reduce oil pressure loss.Positioning support bracer 4 is arranged with between the outside of internal rotor 3 and the inner side of the pump housing 1, between the side of described positioning support bracer 4 and the inner side of the described pump housing 1, the outside that is positioned at internal rotor 3 is arranged with eccentric hoop 5, the outside of described eccentric hoop 5 is arranged with external rotor 6, the side of described external rotor 6 is provided with semiorbicular positioning block 7, and the inner side of the described pump housing 1 is provided with the locating stud 8 abutted with described positioning block 7.By above-mentioned design, not only achieve the direction conversion of oil pump, and simplify the structure, the pump housing 1 is integrated with bearing support, and internal rotor 3 is directly by the crank-driven of air compressor, and installation, maintenance is convenient.
When oil pump rotates forward, one end of positioning block 7 props up locating stud 8, and eccentric hoop 5 is located, when oil pump turns to, eccentric hoop 5 is rotating in same direction 180 ° under the drive of external rotor 6, until the other end of positioning block 7 props up locating stud 8, positioning block 7 is reorientated, and oil pump completes commutation automatically.
In order to improve the end part seal of internal rotor 3, the sealing gland 9 be socketed in outside described internal rotor 3 is provided with in the outside of the described pump housing 1, the inner side of described sealing gland 9 and the outside of described internal rotor 3 are provided with seal ring 10, and are also provided with rubber seal between the end face and the end face of the pump housing 1 of sealing gland 9.Like this, the use of easily damaged parts can be reduced as far as possible, but not affect sealing and fuel feeding effect.Inipple 13 is provided with, for installing speed probe in the end of described sealing gland 9.
One end of described internal rotor 3, the inside for installing transmission shaft is provided with oil circuit 11, to carry out fuel feeding to bent axle.
The described pump housing 1 is provided with observation panel 12, checks that whether oil pump is working properly to facilitate staff.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
