Description
Technical Field
The utility model belongs to an automobile engine spare part especially relates to an engine oil pump cover.
Background
A front cover of an automobile engine is generally integrated with an organic oil pump and comprises a shell, a pump cover, an inner rotor, an outer rotor, an inner rotor shaft, an oil pump chain wheel, a pressure limiting valve and the like, wherein an oil duct is designed on the shell, the inner rotor and the outer rotor are assembled on the shell, when the engine works, friction is inevitably generated between relative motion surfaces of transmission parts such as the rotor shaft and a main bearing, a piston and a cylinder wall, a timing gear pair and the like, the friction between metal surfaces can increase the power consumption in the engine and lead the work surfaces of the parts to be rapidly abraded, and the work surfaces of the parts can be burnt and damaged due to heat generated by friction to cause the engine to be incapable of running, therefore, in order to ensure the normal work of the engine, the relative motion surfaces must be lubricated, namely, the friction surfaces are covered with a layer of lubricating, so as to reduce the friction resistance, reduce the power loss, reduce the abrasion of the machine parts and prolong the service life of the engine.
The oil outlet passage and the oil inlet passage on the existing engine oil pump cover can be mostly provided with a lubricating oil passage for lubricating and then sealed by an oil inlet of the lubricating oil passage, the existing sealing mode is that rivets are pressed for sealing, but the sealing effect is poor, and the requirement on an operator is also high.
Disclosure of Invention
In order to solve the technical problem, the utility model provides an engine oil pump cover.
The utility model discloses a realize above-mentioned purpose and the technical scheme who takes does:
the utility model provides an engine oil pump cover, includes pump cover main part and rotor cavity on set up at least one axle position hole, rotor cavity's both sides set up out oil passage and oil feed route respectively, oil passage and oil feed route on set up the lubricating oil passageway respectively, the oil inlet on lubricating oil passageway on set up seal assembly, seal assembly including having open-ended inner chamber, and including the cavity opening part set up sealed spheroid, set up many sealed beads on the outer wall of inner chamber, only need pass through the stamping workpiece punching press with sealed spheroid to the inner chamber when needs sealed lubricating oil passageway, make many sealed beads of the outer wall of inner chamber through outside inflation locking sealed lubricating oil passageway.
As a further improvement, the section of the inner chamber is of a trapezoidal structure, so that the outer wall of the inner chamber is fully expanded when the sealing ball body is sunken.
As a further improvement, the diameter of the sealing ball is larger than that of the inner chamber.
As a further improvement, the sealing ribs have an inclined angle.
The utility model has the advantages that: the utility model discloses only need pass through stamping workpiece punching press to inner chamber with sealed spheroid when the lubricating oil route is sealed to needs in, make many sealed beads of the outer wall of inner chamber seal the lubricating oil route through outside inflation locking, easy operation and sealed effectual.

Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1-5, an oil pump cover comprises a pump cover main body 1 and a rotor inner cavity 2, wherein at least one axial hole 3 is arranged on the rotor inner cavity 2, an oil outlet passage 4 and an oil inlet passage 5 are respectively arranged at two sides of the rotor inner cavity 2, a lubricating oil passage 6 is respectively arranged on the oil outlet passage 4 and the oil inlet passage 5, a sealing assembly 7 is arranged on the oil inlet of the lubricating oil passage 6, the sealing assembly 7 comprises an inner chamber 8 with an opening, a sealing ball body 9 is arranged at the opening of the inner cavity, a plurality of sealing convex edges 10 are arranged on the outer wall of the inner cavity, when the lubricating oil passage 6 needs to be sealed, only the sealing ball 9 needs to be punched into the inner cavity chamber through the stamping part, so that the plurality of sealing convex edges 10 on the outer wall of the inner cavity chamber are locked to seal the lubricating oil passage 6 through outward expansion, and the plurality of sealing convex edges have inclination angles.
The section of the inner chamber is in a trapezoidal structure or the diameter of the sealing ball body is larger than that of the inner chamber, so that the outer wall of the sealing ball body is fully expanded when the sealing ball body is sunken.
The pump cover main body 1 is further provided with a pressure relief passage 11, the pressure relief passage 11 is communicated with the oil outlet passage 4 and the oil inlet passage 5, and the pressure relief passage 11 is provided with a pressure relief oil return passage 12.
