Abstract
The utility model discloses an aluminum alloy casting of a pump cover of an engine oil pump body for a gasoline engine, which comprises a shell, an active shaft cavity, a pressure-limiting valve cavity, a gear chamber pressure cavity, a pump cover mounting thread hole and a pump body mounting thread hole, wherein the pressure-limiting valve cavity is positioned in the middle of the shell; the active shaft cavity is positioned at one side of the pressure-limiting valve cavity; the gear chamber pressure cavity is positioned at the other side of the pressure-limiting valve cavity; the pump cover mounting thread hole is positioned on the shell and is close to the active shaft cavity; the pump body mounting thread hole is positioned on the shell and is close to the gear chamber pressure cavity. The effective match of the aluminum alloy casting of the pump cover of the engine oil pump body for the gasoline engine and other key part structures meets the using requirements of the engine oil pump of the gasoline engine.
Description
Technical field
The utility model relates to a kind of aluminium alloy castings, particularly a kind of aluminium alloy castings of petrol engine oil pump body pump cover.
Background technique
In petrolic engine oil pump assembly; Because assembly performance parameter and pump housing pump cover coupling require high; Need under engine speed 700-7200rpm condition; Realize lubrication flow 17.33-19.5L/min, the technical specifications of pressure release cracking pressure 4.5-5.5bar are so foundry goods is an important spare part with its immanent structure and profile.The foundry goods design of existing pump housing pump cover can not be effectively and elements such as involute gear, pressure-limit valve, spring force, oil outlet, oil duct flow resistance mate, cause defectives such as engine oil pump assembly flow and pressure instability.
The model utility content
The utility model technical problem to be solved provides a kind of aluminium alloy castings of petrol engine oil pump body pump cover, and effective coupling of itself and other key components and parts structure satisfies the needs that the petrol engine oil pump is used.
For solveing the technical problem; The utility model provides a kind of aluminium alloy castings of petrol engine oil pump body pump cover; It is characterized in that it comprises housing, initiatively axocoel, pressure limiting valve pocket, gear constant pressure chamber, pump cover are installed tapped hole, the pump housing is installed tapped hole, the pressure limiting valve pocket is positioned at the centre of housing; Initiatively axocoel is positioned at a side of pressure limiting valve pocket; Gear constant pressure chamber is positioned at the opposite side of pressure limiting valve pocket, and pump cover is installed tapped hole and is positioned on the housing and near the active axocoel, and the pump housing is installed tapped hole and is positioned on the housing and near gear constant pressure chamber.
The positive progressive effect of the utility model is: effective coupling of the utility model and other key components and parts structures, satisfy the needs that the petrol engine oil pump is used.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The aluminium alloy castings of the utility model petrol engine oil pump body pump cover comprises housing 1, initiatively axocoel 2, pressure limiting valve pocket 3, gear constant pressure chamber 4, pump cover are installed tapped hole 6, the pump housing is installed tapped hole 7; Pressure limiting valve pocket 3 is positioned at the centre of housing 1; Initiatively axocoel 2 is positioned at a side of pressure limiting valve pocket 3; Gear constant pressure chamber 4 is positioned at the opposite side of pressure limiting valve pocket 3, and pump cover is installed tapped hole 6 and is positioned on the housing 1 and near active axocoel 2, and the pump housing is installed tapped hole 7 and is positioned on the housing 1 and near gear constant pressure chamber 4.
Wherein, the diameter equidimension in gear constant pressure chamber and the thickness of involute gear, tooth depth, tooth footpath, sector and flow and flow velocity have formed effective coupling, make gear constant pressure chamber be issued to the smooth and easy outflow of optimum flow and minimum drag in effective vacuum.The spatial volume and the angle of pressure limiting valve pocket have been made design improvement, make spring and spool form effective coupling, realize effective automatically pressure limiting and the outflow of stable high voltage oil.Effective coupling of the utility model and other key components and parts structures satisfies the needs that the petrol engine oil pump is used.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.
