  When manufacturing a valve timing adjusting device in which the driving rotating body and the driven rotating body of the phase adjusting mechanism are respectively connected to the crankshaft and the camshaft as in Patent Document 1, the phase between the rotating bodies is before the connecting step. Must be matched to a predetermined initial phase. However, in the phase adjustment mechanism of Patent Document 1 in which the driven rotator and the input rotator are provided so as to be relatively rotatable with respect to the drive rotator to enable adjustment of the phase between the rotators, the relative rotation between the rotators is achieved. Since the phase is easily shifted, it has become a bottleneck in improving the phase accuracy.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a method for manufacturing a valve timing adjusting device that can obtain high phase accuracy.

  The invention according to claim 1 is a method of manufacturing a valve timing adjusting device that adjusts the valve timing of a valve that opens and closes a camshaft by transmission of engine torque from a crankshaft in an internal combustion engine, As a phase adjustment mechanism for adjusting the phase between the rotating body between the driving rotating body and the driven rotating body that rotate in conjunction with the camshaft, the relative rotation of the input rotating body with respect to the driving rotating body is reduced to follow the driving rotating body. The assembly process for assembling the speed reduction mechanism that converts the relative rotation of the rotating body, and the phase adjustment mechanism assembled by the assembly process, by attaching a common lock jig to the drive rotating body and the input rotating body, the phase between the rotating bodies is initialized. In the locking process for locking to the phase, and the phase adjusting mechanism in which the phase between the rotating bodies is locked by the locking process, the drive rotor and the driven The connecting step of connecting the rolling elements to the crankshaft and the camshaft, and the phase adjusting mechanism in which the driving rotating body and the driven rotating body are connected to the crankshaft and the camshaft by the connecting step, respectively, are locked from the driving rotating body and the input rotating body. A releasing step of releasing the lock of the phase between the rotating bodies by removing the jig.

  According to the present invention, in the locking process, the phase between the rotating bodies is locked to the initial phase by attaching the common locking jig to the drive rotating body and the input rotating body in the phase adjusting mechanism assembled in the assembling process. Here, in the previous assembly process, a speed reduction mechanism that decelerates the relative rotation of the input rotator relative to the drive rotator and converts it into relative rotation of the driven rotator relative to the drive rotator is assembled as a phase adjustment mechanism. Therefore, even if an error due to a manufacturing tolerance or the like occurs in the mounting position of the lock jig with respect to the drive rotator and the input rotator in the lock process, the phase between the rotators between the drive rotator and the driven rotator is determined from the initial phase. It is possible to lock in a state where the deviation is suppressed.

  Moreover, according to the first aspect of the present invention, the releasing step after the connecting step of connecting the driving rotating body and the driven rotating body to the crankshaft and the camshaft, respectively, in the phase adjusting mechanism in which the phase between the rotating bodies is locked by the locking process. Thus, the lock jig is removed from the drive rotator and the input rotator. According to this, the connection of the driving rotating body to the crankshaft and the connection of the driven rotating body to the camshaft can be completed while suppressing the deviation from the initial phase of the phase between the rotating bodies by the above-described locking jig. As a result, high phase accuracy can be secured as a product.

  According to the second aspect of the present invention, in the connecting step, the driven rotating body is screwed in the axial direction with respect to the cam shaft, so that the driven rotating body rotates relative to the drive rotating body by the screwing operation. Is concerned. However, in the connecting step, the phase between the rotating bodies is locked and the relative rotation of the driven rotating body with respect to the driving rotating body is restricted, so the driven body is driven in a state in which the phase shift between the rotating bodies due to the screwing operation is suppressed. The rotating body can be connected to the camshaft.

  According to the third aspect of the present invention, in the connecting step, the annular torque transmission member for transmitting the engine torque from the crankshaft to the drive rotator after the driven rotator is connected to the camshaft, the crankshaft and the drive Hang between the rotating bodies. As described above, when the annular torque transmission member for transmitting the engine torque is passed between the crankshaft and the drive rotary body after the driven rotary body is connected to the camshaft, the drive rotary body is rotated by the passing operation. Is concerned. However, in the connecting step, the phase between the rotating bodies is locked and the relative rotation of the driven rotating body with respect to the driving rotating body is restricted, so even if the driving rotating body is rotated by the spanning operation of the torque transmitting member, The driven rotator also rotates and the phase between the rotators is maintained. Therefore, it is possible to connect the drive rotator to the crankshaft in a state in which a shift in the phase between the rotators due to the torque transmission member spanning operation is suppressed.

  According to the invention of claim 4, in the connecting step, the annular torque transmission member for transmitting the engine torque from the crankshaft to the drive rotator is spanned between the crankshaft and the drive rotator, and then the driven Connect the rotating body to the camshaft. As described above, when the annular torque transmission member for transmitting the engine torque is spanned between the crankshaft and the drive rotor before the driven rotor is connected to the camshaft, the torque transmission member is spanned. The difficult situation can be avoided.

  The invention according to claim 5 is a conveying step of conveying the phase adjusting mechanism, in which the phase between the rotating bodies is locked by the locking step, from the location where the locking step is performed to the location where the connecting step is performed between the locking step and the connecting step. including. Thus, in the conveyance process which conveys a phase adjustment mechanism to the implementation location of a connection process, we are anxious about the situation where the phase adjustment mechanism produces the shift | offset | difference of phase between rotary bodies by the vibration at the time of the said conveyance, contact, etc. However, in the transport process, the phase adjustment mechanism in which the phase between the rotating bodies is locked by the locking process is transported from the place where the locking process is performed. The deviation from the initial phase can be reliably suppressed.

  According to the invention described in claim 6, in the assembling process, the phase adjusting mechanism having the stopper portion for restricting the phase between the rotating bodies to the extreme end phase is assembled, and the locking jig attached to the input rotating body in the locking process. Then, the lock jig is attached to the drive rotator while the input rotator is relatively rotated in the set direction with respect to the drive rotator and the phase between the rotators is regulated to the extreme end phase by the stopper portion.

  In the locking process of the present invention, the locking jig attached to the input rotating body is also attached to the driving rotating body in a state where the phase between the rotating bodies is regulated to the endmost phase, thereby locking the phase between the rotating bodies to the endmost phase. Thus, the extreme end phase can be set as the initial phase. Here, since the stopper portion of the phase adjusting mechanism assembled by the assembly process regulates the phase between the rotating bodies, the extreme end phase is an accurate phase as the initial phase. Further, such an endmost phase can be easily realized by rotating the input rotator relative to the drive rotator in the set direction using a locking jig for locking the phase between the rotators. For these reasons, the phase lock between the rotating bodies can be accurately performed by a simple operation.

According to the invention of claim 7, in the assembly process, assembling a phase adjustment mechanism having an engaging portion and the drive rotor having a fitting portion to the input rotary member extending in the axial direction of the input rotary member, the locking step In this case, the input rotator is rotated relative to the drive rotator in the set direction until the lock jig exceeds the locking portion, and the phase between the rotators is adjusted by the stopper. In a state where the phase is regulated to the extreme end phase, the lock jig is pushed along the fitting portion in the axial direction and is locked from the opposite side to the setting direction by the locking portion.

In the locked process of this invention, the fitting portion phase adjustment mechanism assembled by the assembly process extending in the axial direction has an input rotary member, fitted lock jig for rotating the input rotary member in the setting direction It is attached. According to the lock jig fitted to the fitting portion in this way, the input rotating body can be quickly rotated relative to the driving rotating body until the phase between the rotating bodies reaches the endmost phase where the stopper portion functions. Can do it.

Further, in the locking process of the invention according to claim 7, the locking jig is operated until the phase adjusting mechanism assembled by the assembling process exceeds the engaging part of the driving rotating body, thereby the subsequent fitting part. It is latched by the said latching | locking part through pushing along. At this time, the phase between the rotating bodies is regulated to the endmost phase by the stopper portion, and the locking portion is provided from the opposite side to the setting direction for rotating the input rotating body relative to the driving rotating body for the regulation. Lock the lock jig. As a result, the lock jig is attached not only to the input rotator but also to the drive rotator, and holds the input rotator with respect to the drive rotator so that the input rotator does not rotate relative to the set direction or the opposite side. Become. Accordingly, the phase between the rotating bodies is accurately locked to the endmost phase as the initial phase and surely until the lock jig is removed.

  From the above, in the invention according to claim 7, the phase between the rotating bodies can be accurately locked even by a simple and short-time operation, and furthermore, the locked state can be maintained until the release step, so that the high phase This can contribute to ensuring accuracy.

  The invention according to claim 8 includes a connecting step of connecting the actuator to the input rotating body by fitting an actuator for rotationally driving the input rotating body into the fitting portion after the releasing step. According to the present invention, the fitting portion used for operating the locking jig in the locking step is for connecting the rotation driving actuator of the input rotating body to the rotating body in the connecting step after the releasing step. Used. According to this, it is possible to suppress a cost increase caused by attaching a lock jig to the input rotating body for phase locking and to ensure high phase accuracy.

  According to the ninth aspect of the present invention, in the assembling step, the phase adjusting mechanism having the protruding portion protruding from the drive rotating body as the locking portion is assembled. In the locking process of the present invention, the protrusion protruding from the drive rotating body in the phase adjusting mechanism assembled in the assembling process is used as a locking part for locking the locking jig. According to this, it is possible to suppress a cost increase caused by attaching a lock jig to the drive rotating body for phase locking and to ensure high phase accuracy.

  According to the invention described in claim 10, in the assembling process, the planetary rotator which has an eccentric peripheral surface portion eccentric to the drive rotator in the input rotator and is supported by the eccentric peripheral surface portion via the elastic member is driven. A planetary speed reducing mechanism that changes the phase between the rotating bodies by moving the planet according to the relative rotation of the input rotating body with respect to the rotating body is assembled as a phase adjustment mechanism, and the input rotating body is driven by a lock jig in the locking process. On the other hand, the elastic member is elastically deformed by relative rotation in the set direction, and the locking jig is locked by the locking portion in a state where the phase between the rotating bodies is restricted to the extreme end phase by the stopper portion.

  In the locking process of the present invention, when the input rotating body is rotated relative to the driving rotating body in the setting direction by the locking jig and the phase between the rotating bodies is regulated to the extreme end phase, the elasticity of the phase adjusting mechanism is reached. The member is elastically deformed to generate a restoring force. Here, in the planetary reduction mechanism assembled as a phase adjusting mechanism by the assembly process, the elastic member corresponds to the eccentric peripheral surface portion of the input rotator that is eccentric with respect to the drive rotator and the relative rotation of the input rotator with respect to the drive rotator. It is mediated by a support interface with the planetary rotating body that changes the phase between the rotating bodies by planetary motion. Therefore, according to the elastic member that is elastically deformed between the eccentric peripheral surface portion and the planetary rotating body when the input rotating body rotates relative to the driving rotating body in the set direction in the restricted state of the phase between the rotating bodies, The input rotator can be biased by the restoring force toward the side opposite to the set direction, that is, the locking portion side. As a result of this energization, the ability to hold the input rotator so that it does not rotate relative to the drive rotator in either the set direction or the opposite direction will be improved, greatly contributing to ensuring high phase accuracy. It can be done.

  According to the invention described in claim 11, in the assembling process, the phase adjusting mechanism having a stopper portion for restricting the phase between the rotating bodies to the extreme end phase is assembled, and the locking jig attached to the input rotating body in the locking process. The input rotator is rotated relative to the drive rotator in the set direction by the stopper, and the phase between the rotators is regulated to the extreme end phase by the stopper, and then the input rotator is set to the drive rotator by the lock jig. The lock jig is attached to the drive rotator while the phase between the rotators is adjusted to the intermediate phase by rotating the set amount relative to the opposite side.

  In the locking process of the present invention, the locking jig attached to the input rotating body is also attached to the driving rotating body with the phase between the rotating bodies adjusted to the intermediate phase, so that the phase between the rotating bodies is locked to the intermediate phase. The intermediate phase can be the initial phase. In addition, here, the intermediate phase is opposite to the set direction of the input rotator with respect to the drive rotator based on the extreme end phase where the stopper of the phase adjustment mechanism assembled by the assembly process regulates the phase between the rotators. Since it is realized by rotating the set amount relative to the side, an accurate phase is obtained as the initial phase. Furthermore, such a phase can be easily realized by rotating the input rotator relative to the drive rotator using a lock jig for locking the phase between the rotators. For these reasons, the phase lock between the rotating bodies can be accurately performed by a simple operation.

According to the twelfth aspect of the present invention, in the assembling process, the input rotating body has the first fitting portion extending in the axial direction of the input rotating body and the second fitting portion extending in the axial direction of the input rotating body is driven. Assemble the phase adjustment mechanism in the rotating body, and in the locking process, rotate the input rotating body relative to the driving rotating body in the set direction with the locking jig fitted in the first fitting portion, and rotate the rotating body with the stopper portion. After the interphase is regulated to the endmost phase, the lock is performed under the condition that the input rotator is rotated relative to the drive rotator in the direction opposite to the set direction by the lock jig and the phase between the rotators is adjusted to the intermediate phase. The jig is pushed in the axial direction along the first fitting portion to be fitted to the second fitting portion.

In the locked process of the present invention, locking jig for the first fitting part, for rotating the input rotary member in the setting direction in which the phase adjustment mechanism assembled by the assembly process extending in the axial direction has an input rotary member Is fitted and attached. According to the lock jig fitted to the first fitting portion in this way, the input rotator is moved with respect to the drive rotator until the phase between the rotators reaches the intermediate phase through the endmost phase where the stopper portion functions. The relative rotation can be performed quickly.

The lock jig in lock step of the invention according to claim 12, relative to the second fitting portion in which the phase adjustment mechanism assembled by the assembly process extends in the axial direction of the chromatic perilla the drive rotor, the first It is fitted and attached via pushing along the fitting part. Thus, according to the lock jig fitted to the second fitting portion, the input rotating body can be held relative to the drive rotating body so as not to rotate relative to the set direction or the opposite side. Therefore, the phase between the rotating bodies is accurately locked to the intermediate phase as the initial phase and surely until the locking jig is removed.

  From the above, in the invention according to claim 12, the phase of the rotating body can be locked accurately by a simple and short-time operation, and further, the locked state can be maintained until the releasing step, which is high. This can contribute to ensuring the phase accuracy.

  The invention described in claim 13 includes a connecting step of connecting the actuator to the input rotating body by fitting an actuator for rotationally driving the input rotating body into the first fitting portion after the releasing step. According to the present invention, the first fitting portion used for operating the locking jig in the locking step connects the rotation driving actuator of the input rotating body to the rotating body in the connecting step after the releasing step. Used for. According to this, it is possible to suppress a cost increase caused by attaching a lock jig to the input rotating body for phase locking and to ensure high phase accuracy.

  Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. In addition, the overlapping description is abbreviate | omitted by attaching | subjecting the same code | symbol to the corresponding component in each embodiment.

(First embodiment)
FIG. 1 shows a valve timing adjusting apparatus 1 according to a first embodiment of the present invention. The valve timing adjusting device 1 is mounted on a vehicle and installed in a transmission system that transmits engine torque from a crankshaft (not shown) of an internal combustion engine to a camshaft 2. In this embodiment, the camshaft 2 opens and closes an intake valve (not shown) of the “valve” of the internal combustion engine by transmitting the engine torque, and the valve timing adjusting device 1 controls the valve timing of the intake valve. Adjust.

(Constitution)
Hereinafter, the configuration of the valve timing adjusting device 1 of the first embodiment will be described in detail. The valve timing adjusting device 1 is formed by combining an electric motor 4, an energization control circuit unit 7, a phase adjusting mechanism 8, and the like.

  The electric motor 4 is, for example, a brushless motor or the like, and includes a casing 5 that is fixed to a fixed node of the internal combustion engine and a rotating shaft 6 that is supported by the casing 5 so as to be rotatable forward and backward. The energization control circuit unit 7 includes a drive driver and its control microcomputer, and is disposed outside and / or inside the casing 5 and electrically connected to the electric motor 4. The energization control circuit unit 7 rotationally drives the rotating shaft 6 by controlling energization to the electric motor 4.

  The phase adjustment mechanism 8 is a planetary speed reduction mechanism including a drive rotator 10, a driven rotator 20, an input rotator 40, an elastic member 50, and a planetary rotator 60.

  The drive rotator 10 is formed by coaxially fastening a sun gear 12 and a sprocket 13 both formed in a bottomed cylindrical shape. Here, the sun gear 12 of the present embodiment has protrusions 102 that protrude radially outward from four locations that are substantially equidistant in the rotation direction on the peripheral wall, and each of the protrusions 102 is a sprocket. 13 is screwed to the peripheral wall portion.

  The sun gear 12 forms a drive-side internal gear portion 14 having a tooth tip circle on the inner peripheral side of the root circle by a peripheral wall portion. The sprocket 13 is concentrically fitted to the outer peripheral side of the camshaft 2 and has a plurality of teeth 13a protruding outward in the radial direction. The sprocket 13 is connected to the crankshaft by looping an annular timing chain 15 between the teeth 13a and a plurality of teeth of the crankshaft. Accordingly, when the engine torque of the crankshaft is transmitted to the sprocket 13 through the timing chain 15, the drive rotator 10 rotates in conjunction with the crankshaft. The rotation direction of the drive rotator 10 is set to the clockwise direction in FIGS.

  As shown in FIGS. 1 and 3, the driven rotator 20 has a bottomed cylindrical shape and is concentrically fitted to the inner peripheral side of the drive rotator 10. The driven rotating body 20 forms a connecting portion 21 connected to the cam shaft 2 by a bottom wall portion. Here, the connecting portion 21 of the present embodiment is directly connected to the cam shaft 2 in the axial direction by screwing using a center bolt 24. By this direct connection, the driven rotor 20 can rotate in conjunction with the camshaft 2 and can rotate relative to the drive rotor 10. The rotational direction of the driven rotator 20 is set in the clockwise direction of FIG.

  As shown in FIGS. 1 and 3, the driven rotating body 20 further includes a driven side internal gear portion 22 having a tooth tip circle on the inner peripheral side of the root circle by a peripheral wall portion. The diameter of the driven side internal gear portion 22 is set smaller than the diameter of the drive side internal gear portion 14, and the number of teeth of the driven side internal gear portion 22 is set smaller than the number of teeth of the drive side internal gear portion 14. .

  The driving rotator 10 and the driven rotator 20 are provided with driving side stopper portions 16, 17, 18, 19 and driven side stopper portions 26, 27, 28, 29, respectively. The drive-side stopper portions 16, 17, 18, and 19 protrude radially inward from four locations that are substantially equidistant in the rotational direction on the peripheral wall portion of the sprocket 13. The driven-side stopper portions 26, 27, 28, and 29 protrude radially outward from four locations that are substantially equidistant in the rotational direction on the peripheral wall portion of the driven rotating body 20.

  As shown in FIG. 3, when one specific driven-side stopper portion 26 comes into contact with the driving-side stopper portion 16 in the retarding direction, the relative rotation of the driven rotating body 20 in the retarding direction with respect to the driving rotating body 10 is stopped. Thus, the phase between the rotators is regulated to the endmost phase on the retard side. Here, in the present embodiment, the most retarded phase on the retard side is set to an initial phase for allowing start of the internal combustion engine. On the other hand, when the driven-side stopper 26 abuts on the drive-side stopper 17 in the advance direction, the relative rotation in the advance direction of the driven rotator 20 with respect to the drive rotator 10 is stopped, and the phase between the rotators advances. It is restricted to the extreme end phase on the corner side. In this embodiment, when an abnormality occurs in the stopper portions 26, 16, 17, any one of the driven side stopper portions 27, 28, 29 contacts the driving side stopper portion in the advance angle direction or the retard angle direction. By this contact, the function of regulating the phase between the rotating bodies can be exhibited.

  As shown in FIGS. 1 to 3, the input rotating body 40 has a cylindrical shape as a whole, and a concentric circumferential surface portion 41 that is concentric with the rotating bodies 10, 20, the rotating shaft 6, and the center bolt 24. It is formed by the surface part. The concentric peripheral surface portion 41 is provided with a pair of rectangular groove-shaped fitting portions 42 that open radially inwardly at substantially equal intervals in the rotational direction of the input rotating body 40. Here, the fitting part 42 of the present embodiment is shaped so as to open to both end faces of the rotating body 40 by extending over the entire area of the input rotating body 40 in the axial direction. The input rotating body 40 is connected to the shaft 6 by fitting the joint portion 6a of the rotating shaft 6 to each fitting portion 42 of the concentric peripheral surface portion 41. With this connection, the input rotator 40 can be rotationally driven together with the rotary shaft 6 and can be rotated relative to the drive rotator 10.

  The input rotator 40 further includes an eccentric peripheral surface portion 44 that is eccentric with respect to the rotators 10 and 20 by the outer peripheral surface portion. The eccentric circumferential surface portion 44 is provided with a pair of concave portions 46 that are open toward the radially outer side, and are eccentrically provided toward the eccentric side of the circumferential surface portion 44, and an elastic member 50 that generates a restoring force in each of the concave portions 46. Are individually housed. Here, as the elastic member 50 of this embodiment, the metal leaf | plate spring which has a substantially U-shaped cross section is used.

  The planetary rotator 60 is formed by combining a planetary bearing 61 and a planetary gear 62. The planetary bearing 61 is a radial bearing in which a ball-shaped rolling element 65 is sandwiched between an outer ring 63 and an inner ring 64. Here, the outer ring 63 is fixed to the inner peripheral side of the center hole 66 of the planetary gear 62 by press-fitting. The inner ring 64 is disposed with a predetermined clearance on the outer peripheral side of the eccentric peripheral surface portion 44 of the input rotating body 40. As described above, the planetary bearing 61 transmits the restoring force received from the elastic members 50 to the center hole 66 of the planetary gear 62 while being supported from the inner peripheral side via the elastic members 50 by the eccentric peripheral surface portion 44. It has become.

  The planetary gear 62 is formed in a stepped cylindrical shape and is disposed concentrically with the eccentric peripheral surface portion 44. That is, the planetary gear 62 is eccentrically arranged on the same side as the eccentric peripheral surface portion 44 with respect to the rotating bodies 10 and 20. In the planetary gear 62, a driving-side external gear portion 68 and a driven-side external gear portion 69 having a tooth tip circle on the outer peripheral side of the root circle are formed by a large diameter portion and a small diameter portion, respectively. The number of teeth of the driving side external gear part 68 and the driven side external gear part 69 is set to be smaller than the number of teeth of the driving side internal gear part 14 and the driven side internal gear part 22, respectively.

  The drive side external gear portion 68 is disposed on the inner peripheral side of the drive side internal gear portion 14 and meshes with the internal gear portion 14. The driven-side external gear portion 69 is disposed on the inner peripheral side of the driven-side internal gear portion 22 and meshes with the internal gear portion 22. Here, in the planetary gear 62 of this embodiment that receives the restoring force of each elastic member 50 in the center hole 66 through the planetary bearing 61, the outer gear portions 68 and 69 are pressed against the inner gear portions 14 and 22. It becomes difficult to rattle. As described above, the planetary gear 62 smoothly realizes a planetary motion that revolves around the eccentric center line of the external gear portions 68 and 69 and revolves in the rotation direction of the input rotating body 40.

  The phase adjustment mechanism 8 having the configuration described so far reduces the relative rotation of the input rotator 40 with respect to the drive rotator 10 and converts it into the relative rotation of the driven rotator 20 with respect to the drive rotator 10, so that these rotators 10. , 20 to adjust the phase between the rotating bodies. Specifically, when the rotary shaft 6 rotates at the same speed as the drive rotator 10, and the input rotator 40 does not rotate relative to the drive rotator 10, the planetary gear 62 does not perform planetary motion and the rotator 10. , 20. Therefore, the phase between the rotating bodies that determines the valve timing is maintained.

  Further, when the rotating shaft 6 rotates at a low speed or reversely with respect to the drive rotator 10, the planetary gear 62 performs a planetary motion when the input rotator 40 rotates relative to the drive rotator 10 in the retard direction. Thus, the driven rotor 20 rotates relative to the drive rotor 10 in the retard direction. Therefore, the phase between the rotating bodies is retarded. Further, when the rotary shaft 6 rotates at high speed with respect to the drive rotator 10, when the input rotator 40 rotates relative to the drive rotator 10 in the advance direction, the planetary gear 62 moves in a planetary motion and is driven to rotate. The body 20 rotates relative to the drive rotating body 10 in the advance direction. Therefore, the phase between the rotating bodies is advanced.

(Production method)
Hereinafter, the manufacturing method of the valve timing adjusting device 1 of the first embodiment will be described in detail.

(Assembly process)
In the assembly process, the phase adjustment mechanism 8 shown in FIG. 4 is assembled by combining the metal elements 10, 20, 40, 50, 60 so as to have the above-described configuration.

(Lock process)
In the locking step, a locking jig 80 as shown in FIGS. Specifically, the rotating wheel 82 of the locking jig 80 has an annular shape and has substantially the same inner diameter as the concentric peripheral surface portion 41 of the input rotating body 40. The operation arm 84 of the locking jig 80 protrudes radially outward from two locations that are substantially equidistant in the rotation direction that coincides with the circumferential direction of the rotating wheel 82, and is a linear flat plate that is long in the protruding direction. Presents. The first protrusion 86 of the locking jig 80 protrudes in the axial direction from two locations that are substantially equally spaced in the rotation direction on the rotating wheel 82, and is a rectangular column shape that can be fitted into the fitting portion 42 and is long in the protruding direction. Presents. The second projections 88 of the lock jig 80 project from the projecting side end portions of the operation arms 84 to the same side as the first projections 86 in the axial direction, and each has a long cylindrical shape in the projecting direction. The lock jig 80 is formed of metal, resin, or the like, but is lower than the rotating bodies 10 and 40 that contact the jig 80 as will be described later, for example, so that some degree of elastic deformation is possible. It is desirable to select a material so as to have hardness and to form the selected material.

  In the lock process using such a lock jig 80, first, the drive rotating body 10 of the phase adjusting mechanism 8 assembled as shown in FIG. 4 in the previous assembly process is fixed in a non-rotatable position. Next, in the locking step, as shown in FIG. 7, the first protrusions 86 of the locking jig 80 are individually fitted and attached to the fitting portions 42 of the input rotating body 40 in the phase adjustment mechanism 8. With this fitting, in the present embodiment, each protrusion 102 of the drive rotator 10 and each second protrusion 88 of the lock jig 80 are in a state of being separated from the rotation center line O of the input rotator 40 by substantially the same degree. . Therefore, in order to avoid mutual interference between each protrusion 102 and each second protrusion 88 in the rotation direction of the input rotator 40, at this time, each protrusion 102 and each second protrusion 88 are connected to the input rotator 40. Each first protrusion 86 is pushed in along each fitting portion 42 within a range that does not overlap in the axial direction.

  Subsequently, in the locking step, each operation arm 84 of the locking jig 80 is operated to move the input rotating body 40 together with the rotating wheel 82 of the locking jig 80 with respect to the driving rotating body 10 as shown in FIG. Rotate relative to the set direction S around O. Here, the setting direction S is a retarded direction with respect to the drive rotator 10, that is, a direction in which the driven rotator 20 is relatively rotated with respect to the drive rotator 10 in the retard direction. Therefore, in this embodiment, the driven-side stopper portion 26 of the driven rotator 20 abuts on the drive-side stopper portion 16 of the drive rotator 10, and the phase between the rotators is the most retarded phase (hereinafter referred to as “retard-angle side” The input rotator 40 is rotated relative to the drive rotator 10 in the setting direction S until it is regulated by the “most end phase”. Further, when the phase between the rotating bodies is regulated to the retarded endmost phase, the relative rotation of the input rotating body 40 with respect to the driving rotating body 10 is slightly continued in the setting direction S, so that the lock jig as shown in FIG. The 80 second protrusions 88 are caused to cross in the setting direction S with respect to two specific protrusions 102 (hereinafter referred to as “specific protrusions 102”) of the drive rotating body 10. At this time, each elastic member 50 between the eccentric peripheral surface portion 44 of the input rotator 40 and the planetary rotator 60 that is decentered with respect to the drive rotator 10 is elastically deformed to thereby restrict the phase between the rotators. The relative rotation of the input rotator 40 with respect to the drive rotator 10 is allowed while maintaining. Further, each elastic member 50 is in a state of biasing the input rotating body 40 to the opposite side to the setting direction S by the restoring force generated by the elastic deformation allowing the relative rotation.

  Thereafter, in the locking step, each of the second protrusions 88 and each of the specific protrusions as shown in FIG. 9 with respect to the lock jig 80 in which each of the second protrusions 88 is located at a position beyond each of the specific protrusions 102 in the setting direction S. The first protrusions 86 are pushed along the fitting portions 42 until the 102 overlaps the axial direction of the input rotator 40, and the rotating wheel 82 and the operation arms 84 are brought into contact with the end surface of the drive rotator 10. As a result, in the lock jig 80 that receives the restoring force of each elastic member 50 acting on the side opposite to the setting direction S via the input rotator 40, each specific protrusion 102 of the drive rotator 10 in the fixed state On the other hand, each second protrusion 88 is pressed in the setting direction S. According to the above, since each second protrusion 88 is reliably locked from the opposite side to the setting direction S by each specific protrusion 102 under the restricted state of the phase between the rotating bodies at the retarded side endmost phase, The lock jig 80 is attached to the drive rotating body 10 so as not to rotate relative to the setting direction S or the opposite side.

  As described so far, in the locking process, the phase between the rotating bodies can be locked to the retarded phase endmost phase as the initial phase by attaching the common locking jig 80 to the rotating bodies 10 and 40. . Here, the locking jig 80 is driven to rotate by utilizing the above-described action of regulating the phase between the rotating bodies by the stopper parts 26, 16, the urging action by the restoring force of the elastic member 50, and the locking action by the specific protrusion 102. In the present embodiment attached to the body 10, the phase lock between the rotating bodies is firmly locked. Furthermore, in the present embodiment in which the planetary speed reduction mechanism as described above is employed as the phase adjustment mechanism 8, even if an error due to manufacturing tolerance or the like occurs in the mounting position of the lock jig 80 with respect to the rotating bodies 10 and 40, The phase between the rotating bodies obtained as the output after the deceleration conversion is the one in which the deviation from the retarded angle endmost phase is suppressed. In addition, the operation for rotating the input rotator 40 to the restriction position of the phase between the rotators is easily and quickly performed by the lock jig 80 fitted and attached to each fitting portion 42 of the rotator 40. Is possible. As described above, according to the locking process of the first embodiment, the phase between the rotating bodies can be locked easily and accurately by a short time operation.

(Conveying process)
In the transport process, the phase adjustment mechanism 8 to which the lock jig 80 is attached as shown in FIG. 9 in the previous lock process is removed from the place where the lock process is performed, without removing the jig 80. Transport to the place of implementation. Therefore, the phase adjustment mechanism 8 is used for the next connection process while being locked to the retarded phase endmost phase as the initial phase.

(Connection process)
In the connecting step, first, in the phase adjustment mechanism 8 in which the phase between the rotating bodies is locked to the retarded phase endmost phase as the initial phase by the locking jig 80, the driven rotating body 20 is connected to the camshaft 2 as shown in FIG. And the connecting portion 21 is brought into contact with the end surface of the shaft 2. Next, in the connecting step, the metal center bolt 24 is input through the inner peripheral side of the rotating wheel 82 of the lock jig 80 attached to the phase adjusting mechanism 8 with either of the rotating bodies 10 and 20 being fixed in position. It inserts in the inner peripheral side of the concentric peripheral surface part 41 of the rotary body 40, and the connection part 21 and the cam shaft 2 are screwed in the axial direction with the said volt | bolt 24. FIG. In this embodiment in which the phase between the rotating bodies is locked at this time, the driven rotating body 20 can be substantially prevented from rotating relative to the driving rotating body 10 by the torque applied to the center bolt 24. That is, the driven rotor 20 can be connected to the camshaft 2 in a state in which the deviation from the retarded phase endmost phase of the phase between the rotors is suppressed.

  Thereafter, in the connecting step, as shown in FIG. 10, a metal timing chain 15 is spanned between the sprocket 13 of the drive rotating body 10 and a crankshaft (not shown). At this time, in the present embodiment in which the locked state of the phase between the rotating bodies is continued by the locking jig 80, the driving rotating body 10 is applied to the driven rotating body 20 by the torque acting on the sprocket 13 when the timing chain 15 is passed. Relative rotation can be substantially avoided. In other words, the drive rotator 10 can be connected to the crankshaft in a state in which the deviation of the phase between the rotators from the retarded phase endmost phase is suppressed.

(Release process)
In the releasing step performed after the connecting step, the lock jig 80 attached to the phase adjusting mechanism 8 is opposite to the mechanism 8 along the axial direction of the rotating bodies 10 and 40 as shown in FIG. Displace to. As a result, the first protrusions 86 of the lock jig 80 are pulled out from the fitting portions 42 of the input rotator 40, and the second protrusions 88 of the jig 80 are connected to the specific protrusions 102 of the drive rotator 10. The locked state will be released. That is, the lock jig 80 is removed from the rotary bodies 10 and 40 to release the phase lock between the rotary bodies. At this time, the drive rotary body 10 and the driven rotary body 20 are already crankshaft and camshaft. 2, there is no substantial deviation in the retarded side endmost phase as the initial phase.

(Linking process)
In the connecting step performed after the releasing step, as shown in FIGS. 1 to 3, the metal joint portion 6 a is fitted to each fitting portion 42 of the input rotating body 40 on the rotating shaft 6 of the electric motor 4. The electric motor 4 and the input rotating body 40 are connected. Thereafter, the valve timing adjusting device 1 is completed by electrically connecting the energization control circuit unit 7 to the electric motor 4 as necessary.

  According to the first embodiment described above, the retardation-side endmost phase as the initial phase when the valve timing adjusting device 1 is completed can be secured with high accuracy. In the first embodiment so far, each specific protrusion 102 of the drive rotating body 10 corresponds to a “locking portion” described in the claims, and the electric motor 4 is described in “ The drive-side stopper portion 16 and the driven-side stopper portion 26 correspond to the “stopper portion” recited in the claims.

(Second embodiment)
As shown in FIGS. 12-14, 2nd embodiment of this invention is a modification of 1st embodiment. In the drive rotating body 210 of the second embodiment, the sun gear 212 and the sprocket 213 form a fitting portion 242 in cooperation with each other. Specifically, a part 242a of the fitting portion 242 is a specific one of the four protrusions 202 protruding at substantially equal intervals in the rotation direction on the peripheral wall portion of the sun gear 212, and the shaft of the input rotating body 40. It penetrates and extends in an arc groove shape along the direction. Further, the remaining portion 242b of the fitting portion 242 is formed in a cylindrical hole shape along the axial direction of the input rotator 40 with a portion corresponding to the portion 242a in the peripheral wall portion of the sprocket 213 screwed to each protrusion 202. It extends through.

  In such a manufacturing method according to the second embodiment, the locking step and the releasing step are different from those in the first embodiment. Hereinafter, the locking process and the releasing process of the second embodiment will be described in detail.

(Lock process)
In the locking process of the second embodiment, a locking jig 280 as shown in FIGS. 15 and 16 is used. Specifically, in the locking jig 280, a linear plate-shaped operation arm 284 that protrudes outward in the radial direction of the rotating wheel 82 is provided only at one position in the rotation direction, and one second protrusion 288 is provided from the arm 284. It has a shape protruding to the same side as each first protrusion 86 in the axial direction.

  In the locking process using such a locking jig 280, as shown in FIG. 17, the locking jig 280 is provided for each fitting portion 42 of the phase adjustment mechanism 8 in which the position of the driving rotating body 210 is fixed as in the first embodiment. The first protrusions 86 are fitted and attached. In this embodiment, the fitting portion 242 partially formed by the protrusion 202 in the drive rotator 210 and the second protrusion 288 of the lock jig 280 are rotated in this embodiment by the rotation of the input rotator 40. The center line O is separated from the center line O by substantially the same distance. Therefore, in order to avoid mutual interference between the protrusions 202 and the second protrusions 288 in the rotation direction of the input rotating body 40, at this time, the protrusions 202 and the second protrusions 288 are connected to the axis of the input rotating body 40. Each first protrusion 86 is pushed along each fitting portion 42 within a range that does not overlap in the direction.

  Subsequently, in the locking step, by operating the operating arm 284 of the locking jig 280, the input rotating body 40 together with the rotating wheel 82 of the locking jig 280 is moved with respect to the driving rotating body 210 as shown in FIG. Rotate relative to the surrounding setting direction S. Here, although the set direction S is also a retarded direction in the present embodiment, the initial phase for allowing the start of the internal combustion engine is a specific phase between the most retarded phase on the retarded side and the advanced side in the present embodiment. Therefore, first, the stoppers 26 and 16 of the rotators 20 and 210 come into contact with each other so that the phase between the rotators is retarded on the most retarded side. The input rotator 40 is rotated relative to the drive rotator 10 in the setting direction S. Next, from the state in which the phase between the rotators is regulated to the retard side extreme end phase, the drive rotator is rotated. 10, the input rotator 40 is relatively rotated in the direction opposite to the set direction S. When the relative number of rotations in the direction opposite to the set direction S becomes the set number of rotations as the “set amount”, The second protrusion 288 of the locking jig 280 and the driving rotating body 2 0 and the fitting portion 242 of the to align in the direction of rotation, the rotating body phase is a particular intermediate phase as the initial phase.

  Therefore, after this, in the locking process, the lock jig 280 in which the second protrusion 288 is aligned with the fitting part 242 is used until the second protrusion 88 penetrates the fitting part 242 in the axial direction as shown in FIG. Each first protrusion 86 is pushed in along each fitting part 42, and the rotating wheel 82 and the operation arm 284 are brought into contact with the end surface of the drive rotating body 210. As a result, the second protrusion 288 is fitted to the fitting portion 242 in the axial direction of the input rotating body 40 in a state where the rotating body phase is adjusted to the specific intermediate phase. On the other hand, the lock jig 280 is attached so as not to rotate relative to the setting direction S or the opposite side.

  As described above, in the locking process, the phase between the rotating bodies can be locked to the specific intermediate phase as the initial phase by attaching the common locking jig 280 to the rotating bodies 210 and 40. Here, in the present embodiment in which the lock jig 280 is attached to the drive rotating body 210 by fitting to the fitting portion 242 described above, the phase lock between the rotating bodies is firmly locked. Further, since the planetary speed reduction mechanism is employed as the phase adjustment mechanism 8 as in the first embodiment, even if an error due to manufacturing tolerances or the like occurs in the mounting position of the lock jig 280 with respect to the rotating bodies 210 and 40. The phase between the rotating bodies obtained as the output after the deceleration conversion is such that the deviation from the specific intermediate phase is suppressed. In addition, the operation for rotating the input rotating body 40 can be easily and quickly performed by the lock jig 280 fitted and attached to each fitting portion 42 of the rotating body 40. As described above, according to the locking process of the second embodiment, the phase lock between the rotating bodies can be achieved with simple and short time operation and accurately.

(Release process)
In the releasing step, the lock jig 280 attached to the phase adjusting mechanism 8 is displaced to the opposite side of the mechanism 8 along the axial direction of the rotating bodies 210 and 40 as shown in FIG. As a result, the first protrusions 86 of the lock jig 280 are pulled out from the fitting portions 42 of the input rotating body 40, and the second protrusions 288 of the jig 280 are pulled out of the fitting portions 242 of the drive rotating body 210. It will be. That is, the lock jig 280 is removed from the rotating bodies 210 and 40 to release the lock of the phase between the rotating bodies. At this time, the driving rotating body 10 and the driven rotating body 20 are the same as in the first embodiment. In addition, since the crankshaft and the camshaft 2 are connected, there is no substantial deviation in the specific intermediate phase as the initial phase.

According to the second embodiment described above, the specific intermediate phase as the initial phase can be ensured with high accuracy when the valve timing adjusting device 1 is completed. In the second embodiment so far, the fitting portion 42 of the input rotating body 40 corresponds to the “first fitting portion” recited in the claims, and the fitting portion 242 of the drive rotating body 210 is patented. This corresponds to the “second fitting portion” recited in the claims.
