Abstract
Description
Technical field
The present invention relates to a kind of oil pump, the oil pump that especially a kind of sealing is strong.
Background technique
The effect of oil pump in lubrication system: oil pump effect is after machine oil is brought up to certain pressure, be sent on the moving surface of each part of motor forcibly, fuel pump structure form can be divided into gear type and rotator type two class, gear type oil pump is divided into again internal-gear type and external gear formula, generally the latter is called gear-type oil pump, but the sealing of traditional oil pump is not ideal enough, even can cause the accident that leakage of oil etc. is great, thus normal use is impacted.
Summary of the invention
The object of the present invention is to provide the oil pump that a kind of sealing is strong, to solve the problem proposed in above-mentioned background technology.
The object of the invention is to be achieved by following technical proposals: the oil pump that a kind of sealing is strong, comprise cog, pin, pump cover, lower gear, fixed base, sump, running shaft, oil inlet hole, the pump housing and attachment hole, described in cog and be arranged on the inside of the pump housing; The described below cogged is provided with lower gear; Described pump cover is arranged on the side of the pump housing; Described fixed base is arranged on the bottom of the pump housing; Described fixed base is provided with attachment hole; Described sump is arranged on the inside of the pump housing; Described cogging connects on the rotary shaft; The side of the described pump housing is provided with oil inlet hole; Described cogging is arranged in sump with lower gear; The described pump housing is provided with pin.
Further, described oil inlet hole is provided with seal ring.
Further, cog described in and lower gear carry out connection of rotating by gear.
Further, described attachment hole adopts hexagonal configuration.
Further, the described pump housing adopts Wear resistant anti-high pressure metal to make.
Compared with prior art, the invention has the beneficial effects as follows the oil pump that this kind of sealing is strong, easy to use, the effect of sealing is strong, simultaneously low cost, long service life and quality is light and handy, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is whole structure figure of the present invention;
In figure: 1-cogs, 2-pin, 3-pump cover, 4-lower gear, 5-fixed base, 6-sump, 7-running shaft, 8-oil inlet hole, the 9-pump housing, 10-attachment hole.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention; technological scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is only the present invention's part embodiment; instead of whole embodiments; based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the invention discloses the oil pump that a kind of sealing is strong, comprise cog 1, pin 2, pump cover 3, lower gear 4, fixed base 5, sump 6, running shaft 7, oil inlet hole 8, the pump housing 9 and attachment hole 10, described in cog 1 inside being arranged on the pump housing 9; Described cog 1 below lower gear 4 is installed; Described pump cover 3 is arranged on the side of the pump housing 9; Described fixed base 5 is arranged on the bottom of the pump housing 9; Described fixed base 5 is provided with attachment hole 10; Described sump 6 is arranged on the inside of the pump housing 9; Described cogging 1 is connected on running shaft 7; The side of the described pump housing 9 is provided with oil inlet hole 8; Described cog 1 and lower gear 4 be arranged in sump 6; The described pump housing 9 is provided with pin 2.
Described oil inlet hole 8 is provided with seal ring, strengthens the effect of sealing, make better tightness, thus reach better using effect; Described cog 1 and lower gear 4 carry out connection of rotating by gear, make linkage stronger, the phenomenon of idle running can not be caused; Described attachment hole 10 adopts hexagonal configuration, is convenient to the pump housing 9 and is fixed; The described pump housing 9 adopts Wear resistant anti-high pressure metal to make, and improves the life-span of use, and the strong oil pump of this kind of sealing is easy to use, and the effect of sealing is strong, simultaneously low cost, long service life and quality is light and handy.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
