[alumite]
Driving side rotary body A drive pulley P and shell H by being formed as the aluminum of softer material in the case of, drive pulley P
Easily abrasion is produced because of the friction with drive belt V.Thus, driving side rotary body A is implemented in order to improve the sun of case hardness
Pole oxidation processes, i.e., so-called alumite.Especially, using the teeth portion of drive pulley P and cylindric wall portion W side as pair
As.
But if implementing alumite, the surface roughness on processing unit surface can be deteriorated.Therefore, it is relative to drive
The aggressivenesss such as the dynamic coefficient of friction increase with V can improve, and be possible to the reduced lifetime that can cause drive belt V on the contrary.
[gap]
Therefore, in the present embodiment, as shown in figures 1 and 3, between shell H and foreboard FP and back plate RP, to drive belt V

Formed with foreboard FP or back plate RP the bearing surface W2 abutted surface roughness.
Make shell H bearing surface W2, directly mutually abutted with foreboard FP bearing surface FP1 or back plate RP bearing surface RP1.
Thus, appropriate oil flows out with driving side rotary body A rotation from the gap, and the outside effluent because of centrifugal force
It is dynamic.The oil of flowing reaches the drive pulley P in the outside for being located at shell H and is wound in the drive belt V of the drive pulley P, and lubricates drive belt V.
Certainly, drive belt V uses the drive belt for the material for being adapted to oil lubrication.
In addition, by carrying out alumite, increase bearing surface W2 case hardness to bearing surface W2.Thus, entering
During the fastening of row and foreboard FP and back plate RP, even if the fastening force of fastening bolt 5 is excessive, it can also prevent cylindric wall portion W from sending out
Change shape.
And then if this structure, then it need not be set between cylindric wall portion W and foreboard FP or back plate RP special
Encapsulant, driving side rotary body A structure are simplified.
In this way, if the driving side rotary body A of this structure, then it can simplify the same of driving side rotary body A structure
When, drive pulley P and drive belt V loss are reduced, and obtain the higher valve arrangement for controlling timing of reliability.
It should illustrate, in order to form clearance G, foreboard FP or back plate RP can be also formed by aluminum, and by foreboard FP
Bearing surface FP1 or back plate RP bearing surface RP1 carry out alumite, improve the surface roughnesses of these bearing surfaces.
[groove portion]
In the driving side rotary body A of present embodiment, groove portion 9, above-mentioned groove portion 9 are formed between drive pulley P and cylindric wall portion W

Whole region of the portion 9 outside the connecting portion 6 for connecting cylindric wall portion W and drive pulley P and formed.
The end of groove portion 9 on circumferencial direction reaches side than the 1st convex portion 1 closer to the position of the center side of the 1st convex portion 1
Put.That is, the length circumferentially as each connecting portion 6 in the region clipped by groove portion 9 be formed shorter than with it is each
The length circumferentially of the 1st corresponding convex portion 1 of connecting portion 6.Because by ensuring that the region of groove portion 9 is relative
It is larger in the region for the inner peripheral surface W1 that driven-side rotor B the 2nd convex portion 2 is slidingly contacted at cylindric wall portion W, even in cunning
In the case that wheel P deforms because of drive belt V, it can also make the displacement transfer to cylindric wall portion W position from the 2nd convex portion 2
Slide contact zone separation.
It should illustrate, be not necessarily to make the circumferencial direction length of groove portion 9 to be longer than the slide contact zone of the 2nd convex portion 2
Circumferencial direction length.As long as groove portion 9 and slide contact zone are formed along axis of rotation X radially superposed region, even if should
Overlapping region very little, it can also obtain preventing the displacement transfer of drive pulley P to cylindric wall portion W effect.
In addition, by groove portion 9 as formation, the feelings that driving side rotary body A heats up when internal combustion engine operation
Under condition, the heat is also difficult to be transferred to drive pulley P.Thus, it is possible to prevent drive belt V heat ageing.Originally, by setting groove portion 9,
The usage amount of aluminum can be reduced, can also realize driving side rotary body A lightweight.
On the other hand, various sizes are formed as on width 9a of the groove portion 9 along radial direction.Basically, setting is passed through
Groove portion 9, cylindric wall portion W and drive pulley P is set diametrically to separate, the deformation of drive pulley P will be difficult to be transferred to cylindric wall portion W.But
It is that the width 9a of groove portion 9 is preferably formed as to shell H bearing surface W2 more than width W3.
The shell H of this structure is shaped to make by the extrusion of aluminum.Thus, by the way that the width 9a of groove portion 9 is set to
Bearing surface W2 more than width W3, so as to make the position of drive pulley P be located at from cylindric wall portion W appearance towards direction outside footpath
Position, the external diameter that drive pulley P is formed as specifying, also, accordingly reduce with the part of groove portion 9 extruder output of aluminum.
Now, if the width 9a of groove portion 9 is extremely narrow, the position that groove portion 9 is corresponded to when not only making extrusion finishing die can be excessively very thin, causes
Die forming is difficult, and the life-span of mould can also be reduced.But by the way that the width 9a of groove portion 9 to be formed as to bearing surface W2 width W3
More than, extruding the size at each position of finishing die becomes reasonable, can obtain making easily and the extrusion with durability shapes
Mould.If the width 9a of groove portion 9 is appropriate, the extrusion resistance when extrusion of aluminum shapes reduces, and manufacture efficiency improves.
And then by the way that the width 9a of groove portion 9 to be set to bearing surface W2 more than width W3, tight for example by foreboard FP bolts
It when being fixed in cylindric wall portion W, can prevent from that the fastening force that cylindric wall portion W applies is crossed connecting portion 6 and is transferred to drive pulley P.
Thus, the shape of drive pulley P remains positive round, does not produce rotation and deviates, and can prevent drive belt V from damaging.
＜ other embodiments ＞
Not only shell H, foreboard FP and back plate RP can be also made up of aluminum.
If this structure, then driving side rotary body A weight is greatly reduced.But fixed fastening spiral shell in back plate RP
The internal thread part 8 of bolt 5 is formed as necessary length can bear sufficiently to fasten along the length direction of fastening bolt 5 in advance
Moment of torsion.
As the gap between cylindric wall portion W and foreboard FP or back plate RP, relatively cylindric wall portion W also may make up
The recess diametrically extended with foreboard FP or back plate RP.The recess for example, by machining and die forming or beat quarter and
Formed.If the part obtained by these processing, then outflow position and the discharge of oil can be arbitrarily set, and can
Play more accurate lubrication.
