Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of rotor for belt type phase discriminator as shown in Figure 1 and Figure 2, mainly by rotor subject 12, the first rotor blade 11 and the second rotor blade 13, described the first rotor blade 11 arranges four, described second rotor blade 13 arranges a slice, and the Extreme breadth of the first rotor blade 11 is less than the Extreme breadth of the second rotor blade 13.Described the first rotor blade 11, second rotor blade 13 is trapezoid blades that rotor main body 12 circumference is arranged, and the relatively small end in the first rotor blade 11, second rotor blade 13 is fixedly connected with rotor subject 12, thus the rotor in the present embodiment is made to become the simple five blade structure rotors of structure.After the rotor of this five blade structure is installed in vehicle cam phase discriminator housing, under certain driving torque and oil pressure conditions, compared with the rotor of quaterfoil structure, the thickness of the rotor of this five blade structure can be thinner, thus can effectively reduce its installing space, and effectively alleviate the overall weight of cam phaser, be conducive to the control accuracy improving phase discriminator.
Rotor of the present utility model is used in belt type phase discriminator, and as shown in Figure 3, Figure 4, rotor 1 is arranged in the housing 7 of vehicle cam phase discriminator described phase discriminator, forms the active chamber of vehicle cam phase discriminator between housing 7 and rotor 1.Belt pulley 2 is fixedly connected with housing 7, and front shroud 3 is fixedly connected with housing 7, and housing 7 is also provided with seal ring 6, can prevent the machine oil of phase discriminator inside from leaking out between front shroud 3 and housing 7 by seal ring 6.Camshaft 9 one end through belt pulley 2 and and form Spielpassung belt pulley 2, described rotor 1 and rotor fixed position form interference fit between overlapping 4, form Spielpassung between rotor 1 and front shroud 3; After front shroud 3, rotor fixed position cover 4, rotor 1 are run through in central bolt 8 one end and camshaft 9 one end is connected and fixed, thus camshaft 9, rotor 1 and rotor fixed position are overlapped 4 connect into as a whole, rotor fixed position wherein overlaps 4 pairs of rotors 1 and positions, preventing rotor 1 from beating when rotating, ensureing the coaxality between rotor 1 and belt pulley 2.Described front shroud 3 is tightly connected with screw plug assembly 5, is leaked by front shroud 3 to prevent the machine oil of phase discriminator inside.
In phase discriminator working procedure, front shroud 3, housing 7, belt pulley 2 three are fixedly connected with integral, rotor 1 is relative to housing 7 rotary motion, machine oil enters the active chamber formed by rotor 1 and housing 7 in phase discriminator by the oil duct on camshaft 9, the oil pressure of machine oil forms certain pressure to the first rotor blade 11, second rotor blade 13 on rotor 1, thus the moment of torsion formed rotor 1, be the driving torque of rotor 1.For improving the resistance to oil pressure capacity in rotor 1 work, the first rotor blade 11, second rotor blade 13 can be connected with rotor subject 12 integrated molding, thus the join strength significantly enhanced between the first rotor blade 11, second rotor blade 13 and rotor subject 12, make the resistance to compression of rotor 1, impact resistance is greatly improved.Described the first rotor blade 11 is that symmetry axis rotor main body 12 circumference is symmetrical with the second rotor blade 13, such structure can make the stressed substantially even, consistent of rotor 1, be conducive to the operating life and the working stability that improve rotor 1, and then improve functional reliability and the control accuracy of phase discriminator.
In order to alleviate between rotor 1 and housing 7 because relatively rotating caused wearing and tearing, the operating life of Extending Rotor 1, the end of the first rotor blade 11, second rotor blade 13 on rotor 1 can offer otch 14, and the sealing scraping blade be made up of high-abrasive material is installed in otch 14, both the frictional loss of rotor 1 can have been alleviated by sealing scraping blade, also can reduce the leakage rate of the machine oil in phase discriminator active chamber simultaneously, improve motor VVT (abbreviation of Variable Valve Timing, Variable Valve Time) control stability.
In order to strengthen sealing scraping blade and rotor 1, the reliability after fixing is installed, the otch 14 of described the first rotor blade 11, second rotor blade 13 end is set to U-shaped otch, to prevent sealing scraping blade from coming off when rotor 1 works, improve working stability, the reliability of phase discriminator.It is to be noted, the first rotor blade 11 on rotor 1, second rotor blade 13 and rotor subject 12 can adopt aluminum alloy material to make, lightweight due to aluminum alloy material, ductility is good, be convenient to the first rotor blade 11 by rotor mould, second rotor blade 13 is directly extruded with rotor subject 12, the performance requirement that this integrated molding processing mode adds cutter to machine is lower, and manufacturing efficiency is higher, both the deadweight of rotor 1 can have been alleviated, and then effectively alleviate the overall weight of cam phaser, the quality stability of rotor 1 can also be ensured, conformity, and reduce the cost of production of rotor 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
