Description
Technical field
The utility model relates to gear oil pump technical field, is specifically related to the gear oil pump that oil is altered in a kind of minimizing.
Background technique
Oil altered by gear pump and outside framework oil seal punctures and overflows by hydraulic oil, this phenomenon ubiquity, has a strong impact on the normal work of loader and the operational safety of gear pump and environmental pollution.Cause the reason of altering oil except the quality problems of outside framework oil seal itself, also may owing to there is certain departing between the rotating shaft of installation process middle gear oil pump and the rotating shaft of gearbox.The installation requirement coaxality of general gear oil pump and gearbox is less than 0.05, if exceed this coaxality, easily beats, and forms cumulative error, causes gear oil pump to bear radial force under High Rotation Speed state, cause outside framework oil seal to alter oil.
Model utility content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, a kind of minimizing is provided to alter the gear oil pump of oil, this gear oil pump should be able to be avoided occurring departing between the rotating shaft of installation process middle gear oil pump and the rotating shaft of gearbox, thus minimizing outside framework oil seal alters oil, and have the advantages that structure is simple, cost is lower, easy to operate.
For realizing above object, the utility model have employed following technological scheme:
The gear oil pump of oil is altered in a kind of minimizing, comprise oil pump main body, it is characterized in that: the side of the rotating shaft end cap of described oil pump main body is provided with a reference rings, the internal diameter of this reference rings and the rotating shaft of oil pump main body matches and coaxial sleeve is located in rotating shaft, reference rings and rotating shaft end cap offer several tapped holes and at least one positioning hole one to one, described tapped hole and positioning hole and shaft parallel are arranged, reference rings is fixed on rotating shaft end cap by some bolts and described tapped hole, separately there is at least one locating stud through matching in the positioning hole inserting rotating shaft end cap after the positioning hole in reference rings.
Be provided with gasket ring between described reference rings and rotating shaft end cap, this gasket ring coaxial sleeve is located in rotating shaft, gasket ring offers and several tapped holes described and at least one positioning hole one group of through hole one to one.
Described tapped hole and the spaced arrangement of positioning hole, and overall uniform ring is arranged around the shaft.
The internal diameter of described gasket ring is greater than the external diameter of rotating shaft.
The beneficial effects of the utility model are: in the utility model, reference rings is bolted on after on rotating shaft end cap, if there is bias in rotating shaft in installation process, then the positioning hole of reference rings can depart from the positioning hole of rotating shaft end cap, locating stud is through after the positioning hole of reference rings, the positioning hole of rotating shaft end cap cannot be inserted, now can reinstall, until locating stud can insert the positioning hole of rotating shaft end cap, thus can effectively reduce cause because of coaxality problem in installation process alter oily phenomenon, easy to use, structure is simple, and cost is lower.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the enlarged diagram in A portion in Fig. 1.
Fig. 3 is the scheme of installation of reference rings and rotating shaft end cap.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1-Figure 3, the gear oil pump of oil is altered in a kind of minimizing described in the utility model, comprise oil pump main body 1, the side of the rotating shaft end cap 2 of described oil pump main body is provided with a reference rings 10, the internal diameter of this reference rings and the rotating shaft 4 of oil pump main body matches and coaxial sleeve is located in rotating shaft, reference rings and rotating shaft end cap offer several tapped holes 6 and at least one positioning hole 8 (being 3 positioning holes in Fig. 3) one to one, described tapped hole and positioning hole and shaft parallel are arranged, reference rings is fixed on rotating shaft end cap by some bolts 5 and described tapped hole, separately there is at least one locating stud 3 through matching in the positioning hole inserting rotating shaft end cap after the positioning hole in reference rings.Described locating stud, positioning hole, tapped hole are fine finishing to improve precision.
Be provided with gasket ring 7 between described reference rings and rotating shaft end cap, this gasket ring coaxial sleeve is located in rotating shaft, gasket ring offers and several tapped holes described and at least one positioning hole one group of through hole 9 one to one.Described tapped hole and the spaced arrangement of positioning hole, and overall uniform ring is arranged around the shaft.The internal diameter of described gasket ring is greater than the external diameter of rotating shaft, and gasket ring effect increases the distance between reference rings and rotating shaft end cap, thus amplified by the eccentric degree of rotating shaft, if there is less bias, locating stud still cannot insert.
Described reference rings, gasket ring all adopt metal to make, such as iron or steel.
