Abstract
The invention relates to an oil duct of a novel camshaft phase regulator. The oil duct comprises a chain wheel, a stator, a rotor and a rear cover, wherein the stator is connected to the rear end of the chain wheel; the rear cover is connected to the rear end of the stator; the rotor is arranged in a cavity formed by the chain wheel, the stator and the rear cover; the rear cover, the stator and the chain wheel are fixed by screws; special-shaped ends for the screws to penetrate through are arranged at the inner circumference of the stator; a special-shaped cavity is formed between every two adjacent special-shaped ends; special-shaped claws which are arranged in the special-shaped cavities and are attached to the inner walls of the special-shaped cavities are arranged at the outer circumference of the rotor; each special-shaped cavity is divided into an inlet angle cavity and a lag angle cavity by the special-shaped claw; special-shaped oil grooves communicating with the inlet angle cavities or the lag angle cavities are formed in the upper surface of the rotor; and oil holes are formed between the specials-shaped oil grooves and the upper surface of the rotor. The oil duct has the advantages that the oil holes are changed into the special-shaped oil grooves and are formed in the end face of the rotor; in addition, a die can be obtained, the manufacturing cost of the rotor is reduced, and the working efficiency is improved; and good consistency of production by the die is realized.
Description
Technical field
The present invention relates to a kind of Novel camshaft phase regulator oil duct.
Background technology
VVT can optimize valve characteristic parameter, improve electromotor inlet and outlet performance, meet electromotor requirement of dynamic property, economy, toxic emission when high rotating speed is with the slow-speed of revolution, big load and Smaller load, overall raising engine performance preferably. Now, one of changeable air valve technology pass machine technology having become measured engine performance.
Cam axle phase regulator as VVT actuator mainly by: sprocket wheel, stator, rotor, lockable mechanism form. When cam axle phase regulator works, machine oil enters a type of cavity (such as advance angle cavity) of cam axle phase regulator from the oil hole camshaft. Thus drive rotor rotates, it is achieved adjust the function of camshaft phase. When the rotor is turning, the machine oil of another chamber (such as phase lag cavity), along the oil duct of cam axle phase regulator, camshaft oil gallery, is eventually returned in electromotor oil cylinder.
At present, the oil duct form of cam axle phase regulator is substantially by boring realization on rotor. This design machines due to needs, and manufacturing cost is higher and more because of hole on rotor, and working (machining) efficiency is relatively low. Accordingly, it would be desirable to seek a kind of new technology to solve this problem.
Summary of the invention
It is an object of the invention to: for above-mentioned deficiency, it is provided that a kind of Novel camshaft phase regulator oil duct.
For achieving the above object, the technical solution used in the present invention is:
A kind of Novel camshaft phase regulator oil duct, including sprocket wheel, stator, rotor and bonnet, sprocket wheel rear end is connected to stator, stator rear end is connected to bonnet, sprocket wheel, it is provided with rotor in the cavity that stator and bonnet are formed, bonnet, fixed by screw between stator and sprocket wheel, stator inner circumferential is provided with mean for the special-shaped end of screw traverse, special-shaped cavity is formed between adjacent two special-shaped ends, the periphery of rotor is provided with and is placed in special-shaped cavity and paralycus that the inwall with special-shaped cavity is fitted, special-shaped cavity is divided into advance angle cavity and phase lag cavity by paralycus, the upper surface of rotor offers the special-shaped oil groove of connection advance angle cavity or phase lag cavity.
Special-shaped oil groove is two, and every special-shaped oil groove connects adjacent two advance angle cavities or phase lag cavity.
In technique scheme, rotor adopts powder metallurgy sintered method to obtain, for the rotor of powder metallurgy sintered acquisition, special-shaped oil groove can by rotor powder metallurgy pressing molding time obtained by mould, solve the cam axle phase regulator rotor oil hole mach problem of needs.
Due to the application of technique scheme, the present invention compared with prior art has the advantage that
Oilhole is become special-shaped oil groove, and is arranged on rotor end-face, and mould can be had to obtain, reduce the manufacturing cost of rotor, improve work efficiency, and good by mould conformity of production.

Special-shaped oil groove 31 is two, and every special-shaped oil groove 31 connects adjacent two advance angle cavities 71 or phase lag cavity 72.
Rotor 3 adopts powder metallurgy sintered method to obtain, rotor 3 for powder metallurgy sintered acquisition, special-shaped oil groove 31 can by rotor powder metallurgy pressing molding time obtained by mould, solve the cam axle phase regulator rotor oil hole mach problem of needs.
Oilhole is become special-shaped oil groove 31, and is arranged on rotor 3 end face, and mould can be had to obtain, reduce the manufacturing cost of rotor 3, improve work efficiency, and good by mould conformity of production.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from principle of the present invention; can also making some improvement or replacement, these improve or replace and also should be regarded as protection scope of the present invention.
