The preferred embodiment explanation
At first, with reference to Fig. 1, the valve timing control gear of a vane rotor is used in 2 explanations.Fig. 1, the cross section of the valve timing control gear shown in 2 is mutually perpendicular plane.
The shell part that this timing gear 1 and watt shape housing 3 constitute as the driving side revolving meber.This timing gear 1 and a watt shape housing 3 utilize screw 20 fixing coaxially.Peripheral wall 4 makes an integral body with front end-plate 5.This front end-plate 5 is a sidewall on a side of this watt shape housing 3.This timing gear 1 is formed in a sidewall on the opposite side of this housing member.
As shown in Figure 2, this watt shape housing 3 has at circumferencial direction with regular basically spaced boots 3a, 3b and 3c.These boots 3a, 3b and 3c make trapezoidal shape.Contiguous mutually boots 3a, 3b and 3c form three gaps at circumferencial direction.This gap is fan-shaped space 40, and these spaces are respectively blade (blade-section) 9a that holds as blades, the chamber of 9b and 9c.Boots 3a, the cross section of each inner periphery of 3b and 3c makes circular shape.That is, as shown in Figure 2, vane rotor 9 has at circumferencial direction with regular basically spaced blade 9a, 9b and 9c.Each blade 9a, 9b and 9c are placed in the space of corresponding fan-shaped rotationally.
As shown in Figure 1, this vane rotor 9 and sleeve 6 utilize a screw integrally to be fixed on this camshaft 2, constitute the revolving meber that is driven side.With this vane rotor 9 integrally stationary sleeve 6 engage with the inner periphery of this front end-plate 5, can relatively rotate with respect to each other.The inner periphery of the outer periphery of this vane rotor 9 and this watt shape housing 3 forms a little gap between them, make this vane rotor 9 to rotate with respect to this watt shape housing 3.Sealing 16 respectively with blade 9a, the outer periphery of the projection section 9d of the outer periphery of 9b and 9c and this vane rotor 9 engages.Sealing part 16 is respectively by spring 17 skews.Each Sealing 16 restraint of labour oil is by the clearance leakage between the hydraulic pressure cavity adjacent one another are.
Form the angled hydraulic pressure cavity 10 of returning between boots 3a and the blade 9a.Form the angled hydraulic pressure cavity 11 of returning between boots 3b and the blade 9b.Form the angled hydraulic pressure cavity 12 of returning between boots 3c and the blade 9c.Form the angled hydraulic pressure cavity 13 of advancing between boots 3a and the blade 9b.Form the angled hydraulic pressure cavity 14 of advancing between boots 9b and the blade 9c.Form the angled hydraulic pressure cavity 15 of advancing between boots 9c and the blade 9a.
In said structure, camshaft 2 and vane rotor 9 can relatively rotate with respect to this timing gear 1 and watt shape housing 3 coaxially.
As Fig. 1, shown in 2, guiding annulus 19 usefulness press machinees are pressed in the receiving bore 23 of making on the inwall of blade 9a, make of the inwall supporting of this guiding annulus 19 by this blade 9a.A block piston 7 inserts in this guiding annulus 19.This block piston 7 is placed among this blade 9a, makes this block piston 7 to slide at the axial direction of camshaft 2.In addition, this block piston 7 is offset to the side of front end-plate 5 by spring 8.Compressing of biasing force by this spring 8, this block piston 7 can engage with a block hole 22 of making on this front end-plate 5.Communication passage 24 of making in this timing gear 1 is communicated with receiving bore 23 on the right side of flange part 7a, and to atmosphere opening, therefore, moving of this block piston 7 do not hindered.
In Fig. 1, the hydraulic channel of the hydraulic pressure cavity 37 on the left side of this flange part 7a by not illustrating is communicated with this angled hydraulic pressure cavity 10 of returning.This is angled when returning in the hydraulic pressure cavity 10 when working oil is sent into, and this block piston 7 overcomes the biasing force of spring 8, is pulled out from this block hole 22.In the head portion of this block piston 7, form a hydraulic pressure cavity 38.As shown in Figure 2, this hydraulic pressure cavity 38 is communicated with by the angled hydraulic pressure cavity 15 of advancing of a hydraulic channel 39 and this.Therefore, in the time of in working oil being sent into this angled hydraulic pressure cavity 15 of advancing, this block piston 7 overcomes the biasing force of spring 8, is pulled out from this block hole 22.
When camshaft 2 was in delay position with respect to bent axle, this block piston 7 engaged with this block hole 22.That is, when this vane rotor 9 with respect to watt shape housing 3 during in delay position, this block piston 7 engages with this block hole 22.This block piston 7 and this block hole 22 constitute a locking mechanism.
With sleeve 6 position contacting on, in the projection section 9d of this vane rotor 9, form a hydraulic channel 29.With camshaft 2 position contacting on, in the projection section 9d of this vane rotor 9, form a hydraulic channel 33.This hydraulic channel 29 is communicated with hydraulic power supply that does not illustrate or oil drain out by hydraulic channel 25,27.This hydraulic power supply is as a drive unit.This hydraulic channel 29 also by hydraulic channel 30,31 and 32 with this angled return hydraulic pressure cavity 10,11 and 12 connections; Also can be communicated with hydraulic pressure cavity 37 by a hydraulic pressure cavity that does not illustrate.
Secondly, the work of this valve timing control gear is described.When this motor in normal working conditions the time, utilize to be supplied to this angled hydraulic pressure cavity 10,11 and 12 and the hydraulic pressure of the working oil of angled advance hydraulic pressure cavity 13,14 and 15 of returning, this block piston 7 is pulled out from this block hole 22.Therefore, this vane rotor 9 rotates with respect to this watt shape housing 3.Therefore the hydraulic pressure of control action in each hydraulic pressure cavity can control the phase difference of camshaft 2 with respect to bent axle.
When this motor stops, working oil do not send into this angled return hydraulic pressure cavity 10,11 and 12 and this angled aforementioned hydraulic chamber 13,14 and 15 in.Therefore, as shown in Figure 2, this vane rotor 9 stops at the delay position with respect to this watt shape housing 3.Working oil is not supplied in the hydraulic pressure cavity 37,38, the feasible biasing force that utilizes this spring 8, and this block piston engages with this block hole 22.
Even when this motor restarts, this block piston 7 keeps engaging with this block hole 22, send into this angled hydraulic pressure cavity 10 of returning until working oil, 11 and 12 and these angled advance hydraulic pressure cavity 13,14 and 15 in till, make this camshaft 2 remain on the position maximum with respect to returning of bent axle.Like this, this vane rotor 9 is locked on this front end-plate 5, till working oil is supplied in each hydraulic pressure cavity, makes and can protect this watt shape housing 3, can be owing to passive this vane rotor 9 that collides of cam moment of torsion.
Below, the manufacture method and the manufacturing installation of the vane rotor 9 that uses in this valve timing control gear are described.This watt shape housing 3 can utilize the manufacture method manufacturing described in the reference JP-A-117717.
As Fig. 1, shown in 2, this vane rotor 9 comprises projection section 9d and a plurality of blade 9a, 9b and 9c.This projection section 9d is essentially cylindrical shape.This blade 9a, 9b and 9c and this projection section 9d make an integral body, make this blade 9a, and 9b and 9c raise from the outer periphery of this projection section 9d, and extend at the radial direction of this projection section 9d.For example, the material of manufacturing can be made by model casting by aluminium, and its shape is equivalent to blade 9a, 9b and 9c and projection section 9d.This manufactured materials is carried out machining such as cutting one class, form hydraulic channel and screw hole, make and to make this vane rotor 9.Can make cylinder iron and the metallic material of other materials, replace aluminium as this vane rotor 9.
When this manufactured materials is carried out machining, clamp and fix this vane rotor 9.Clamp the clamp device 50 of this vane rotor 9 referring now to Fig. 3,4 explanations.
This clamp device 50 has three clamp jaws of arranging along the periphery of this vane rotor 9 with regular basically interval 51,52 and 53.On the head portion of each clamp jaw 51,52 and 53, form two projection 51a, 51b.In this head portion, these two projection 51a, 51b makes fork shape.This projection 51a, 51b contacts with the projection section 9b of this vane rotor 9, compresses its outer surface, thereby supports this vane rotor 9 rigidly.Each clamp jaw 51,52 and 53 is all made by Cr-Mo steel.Best, this all carburizing of clamp jaw 51,52 and 53 is to strengthen anti-ablation ability.
This clamp device 50 has the drive part of this clamp jaw 51,52 and 53 respectively, makes this clamp jaw 51,52 can correspondingly contact with this vane rotor 9d and remove from this vane rotor 9d with 53.Referring now to Fig. 4 this drive part is described.For the ease of understanding, Fig. 4 only is expressed as this projection section 9d workpiece, only represents that clamp jaw 51 is as clamp jaw.
This clamp jaw 51 is fixed on the moving element 54.This moving element 54 comprises a driving source such as motor one class, makes this moving element 54 can utilize this drive source drives power to move as straight line on track 55.The driving source that this moving element 54 is moved can be located at the outside of this moving element 54.This clamp device 50 has a pedestal 56 that can be temporarily fixed on this vane rotor 9.
When clamp device 50 clamped these vane rotors 9, this clamp jaw 51,52 and 53 was installed on the position spaced, at this moment, this clamp jaw 51,52 and 53 and this vane rotor 9 separate.This vane rotor 9 temporarily is fixed on this pedestal 56, then, and at each clamp jaw 51, this projection 51a that 52 and 53 head portion forms, this drive part moves in the 51b, makes this projection 51a, and 51b contacts with this projection section 9d of this vane rotor 9.Then, this drive part produces driving force, and each clamp jaw 51,52 and 53 is added in predetermined compressive force on this projection section 9d.
This clamp device 50 clamps this vane rotor 9 in this way.The machining of utilizing 60 pairs of these vane rotors 9 of facing cutter to carry out such as cutting one class, make and to make screw hole by being machined on this projection section 9d, a hydraulic channel and a seating face that holds this sleeve 6, this facing cutter 60 is as a kind of machinery processing apparatus.
Screw hole, the machining accuracy of seating face etc. is very big to the sealability influence of each hydraulic pressure cavity.Therefore, when utilizing facing cutter to carry out cutting, this clamp device 50 must be bearing in the fixed position with this vane rotor 9.Like this, when being clamped by this clamp device 50, this vane rotor 9 is from the projection 51a of this clamp jaw 51,52 and 53, and 51b accepts big compressive force.
Therefore, as the projection 51a of this vane rotor 9, when 51b accepts compressive force, can limit this vane rotor 9 and produce distortion from this clamp jaw 51,52 and 53.Like this, as shown in Figure 5, this projection 51a that on the head portion of clamp jaw 51,52 and 53, forms, the clamped position of 51b is set in respect to blade 9a, on the side, outer periphery of this projection section 9d of the position that 9b and 9c begin to raise.That is, clamped position is set on the position of outer periphery of this projection section 9d, leaves blade 9a simultaneously, 9b, this blade 9a that the position of 9c begins to raise, 9b, 9c.
As shown in Figure 2, hydraulic channel 30～32 and 34～36 can be at blade 9a, forms near the 9b, the beginning raised position of 9c.In this structure, clamped position moves at circumferencial direction or axial direction, makes this clamped position leave the position that forms hydraulic channel.
The projection 51a that on the head portion of clamp jaw 51,52 and 53, forms, the clamped position of 51b can with blade 9a, the initial position that 9b and 9c raise is overlapping.In this structure, from this projection 51a, the added compressive force of 51b can only act on blade 9a unevenly, on the part of the pedestal of 9b and 9c, or only acts on blade 9a, on the side of 9b and 9c.As a result, this blade 9a, 9b and 9c can be out of shape makes blade 9a, 9b and 9c tiltable or be squeezed.When at blade 9a, when producing this distortion among 9b and the 9c, blade 9a, the sealability of 9b and 9c is possible insufficient, makes working oil leak between hydraulic pressure cavity.
Therefore, as mentioned above, clamp jaw 51,52 and 53 projection 51a, the clamped position of 51b is set in and leaves blade 9a, and on the outer periphery of this boss 9d of 9b and 9c, when vane rotor 9 clamped, blade 9a, 9b and 9c produced and are out of shape with restriction.
As shown in Figure 6, projection 51a, the clamped position of 51b is set as follows.For example, mark basically movable direction, the imaginary line stretcher that stretches out from clamped position along this each clamp jaw 51,52 and 53.This line stretcher is dropped on as much as possible be centered around in the thickness range of cylindrical part of the screw hole that the center of this projection section 9d makes.
Like this, at the projection 51a of compressive force, on the direction of 51b effect, there is not the screw hole of making by cutting from this clamp jaw 51,52 and 53., exist on the line stretcher of 51b effect along the projection 51a of its compressive force along the cylindrical part of this screw hole from this clamp jaw 51,52 and 53.Therefore, accept from this projection 51a, the intensity of the projection section 9d of the compressive force that 51b comes can improve, and makes can limit this projection section 9d because from this projection 51a the added effects of compressive of 51b and produce distortion.
As shown in Figure 6, in order to satisfy above-mentioned relation with respect to clamped position, each clamp jaw 51,52 and 53 projection 51a, the distance between the 51b (pawl width) can be set at and equate with the radius R 1 in the hole of making at the center of this projection section 9d or bigger two times than radius R 1.That is, each clamp jaw 51,52 and 53 width can be set at and equate with the radius R 1 in the hole of making at the center of this projection section 9d or bigger two times than radius R 1.Yet each blade 9a, 9b and 9c are placed between two clamp jaws 51,52 and 53 of mutual vicinity.Therefore, when the internal diameter R1 of this projection section 9d and the difference between the external diameter R2 are big, above-mentioned relation can be easily satisfied, blade 9a can be avoided, 9b and 9c simultaneously all clamped positions.
The line stretcher that stretches out from clamped position drops on the relation in the thickness range of this cylindrical part, may not satisfy for all clamped positions.On the head portion of each pawl of three clamp jaws 51,52 and 53, form two projections, make 6 projections form 6 clamped positions altogether.When at least a portion in these 6 clamped positions satisfied above-mentioned relation, this structure was effective limiting that this projection section 9d produces aspect the distortion.
In addition, as shown in Figure 7, clamp jaw 51,52 and each projection 51a of 53,51b has a contact surface that contacts with this projection section 9d.This contact surface is essentially the R shape, can limit the distortion of this projection section 9d.
In this case, with the projection 51a of this clamp jaw 51,52 and 53, when the surface friction drag between the outer periphery of 51b and this projection section 9d is big, this clamp jaw 51,52 and 53 projection 51a, 51b can stick on the outer periphery of this projection section 9d.As a result, excessive pressure can concentrate on the outer periphery of this projection section 9d and this projection section 9d can be out of shape.
Therefore, with the projection 51a of clamp jaw 51,52 and 53, each surface of contact of 51b makes and is essentially the R shape, to reduce the projection 51a of this clamp jaw 51,52 and 53, the surface friction drag between the outer periphery of 51b and this boss 9d.Like this, when limits excessive when sticking on the outer periphery of this projection section, this clamp jaw 51,52 and 53 projection 51a, 51b slippage on the outer periphery of this projection section 9d easily.Therefore, when this clamp jaw 51,52 and 53 clamps this projection section 9d, can limit this projection section 9d and produce distortion.
As an example of the foregoing description, illustrated and utilized three clamp jaws 51,52 and 53 to clamp this vane rotor 9 as a workpiece.Yet the number of clamp jaw can be equal to or greater than 4.
In the above-described embodiments, this vane rotor 9 comprises three blade 9a, 9b and 9c.Yet the number of blade can maybe can be equal to or greater than 4 for 2.
In the above-described embodiments, each clamp jaw 51,52 and 53 is placed on the blade 9a of mutual vicinity, between 9b and the 9c.Yet the part of clamp jaw or all clamp jaws can be placed to the length that makes this projection to be increased, and makes blade be placed in the space between this projection.
In the above-described embodiments, make hole of inserting screw 21 and the top that screw 21 is screwed into camshaft 2, make this vane rotor 9 be fixed on this camshaft 2 at the center of this projection section 9d.Yet, can on the projection section of this vane rotor, make a hole, make this camshaft can insert in this hole and a nut can be screwed on the top of inserting the camshaft in this hole, make and this camshaft can be fixed on this vane rotor.In this case, the structure of this vane rotor and camshaft can be as described in the reference JP-A-2002-295209.
In the above-described embodiments, this watt shape housing 3 rotates with bent axle, and this vane rotor 9 rotates with camshaft 2.Yet this vane rotor can rotate with bent axle, and this watt shape housing can rotate with camshaft.
In the above-described embodiments, this projection section is essentially the porose cylindrical shape of core.Yet its profile is not to only limit to circle, can be polygon.
Under the condition that does not depart from spirit of the present invention, can be used for various modifications and change the foregoing description.
