Fortunately, the main gear of the first embodiment is explained to explain the configuration. ::5 is composed of a gear a and a gear b having the same tooth period and the same diameter, and is composed of 4 = ~ C, and is disposed coaxially and sandwiched between the gear a and the gear 而 to be superposed. The gear A has a missing tooth portion % lacking a partial tooth. B is an annular shape with external teeth 35 and inner #36, and the external teeth 35 are free of parts, which are full-toothed external teeth, and internal teeth 36 are also full-toothed internal teeth, formed by 319228 1326100* 36 :: The relative rotation direction of the slanting gear eight) The smashing cup 17 is therefore a rush. Gear C # g 士 π this wheel plate 37 and small (four) plate 38 each other # "... 猹 sauce wheel at the same phase with the 嵩 wheel A and the small diameter disk 38 of the tooth of the gift plate 37 is the part of the wheel Correction, the central portion gear B. The inner diameter portion of the inner return 36, the missing tooth portion 34a of the support gear A is disposed in the same phase as the tooth, and the missing portion 34b is fixed to the circumferential gear C, * In the phase-to-phase state, between the gears A and A and the gear C, the gear is clamped to the gear A and the gear c: by the second gear, and the gear plate C is supported by the crankshaft 38. The floating gear that is rotated by the _^/ mesh for the gear A and the gear C from the embodiment of the diameter of 38 on the 'in this implementation, the use of the return to t9b, and in the direction of the center of the groove" The portions 41a, 41b are in the outer direction (the opposite direction toward the gear C; the inclination of the front end of the adjacent 41a, 41b is slowed down (relative to the relative rotation direction of the gear B). The gear A and the gear 6 of the main gear 5 illustrate the engagement and rotation of the gear B with the gear A and the gear B by the pick-up. Fig. 4 shows the engagement and rotation of the gear C and the gear B. , the gear wheel A is fixed as a body, and the illustration of the gear A is omitted here.

The order of (4), (4), (4), and (1) passes through I (a), and the heart heat is not pressed by the gear c oxygen gamma γ 41a 40 " ” 4ϋ and is engaged with the internal teeth 319228 13 1326100 36 of the gear B. The inclination of the portion 41a and the inclination of the internal tooth % cause the j-contact portion to be in a state in which the engagement is unremovable, and the gear C and the record B are formed into a body, and the wire B and the gear c are simultaneously rotated. When the claws of the wheel C are engaged with the internal teeth % of the gear B (the state of Fig. 4 (4)), the teeth of the gear c and the teeth of the gear b are configured to form the same phase. In Fig. 8 (8), the gear [constrained, the gear (4) is rotated by the inertia of the drive = described). At this time, due to the gear = ', the inclination of the ^ part ... and the inclination of the internal teeth 36 will moderate each other. 41a will be pushed into the center direction and disengaged, so that the engagement == wheel B can rotate against the gear C. The same state is also shouting that the figure 4 (c), (d), the figure shows the soil The state of the center of the heart. ^The middle part is the claw part... It is pushed in slowly. The fourth figure (e) shows that the gear B stops. The guide starts to rotate again. In addition, the claw portion 4 is closed by the return spring 4 () toward the outer side 41b and the inner tooth 36 is engaged, and the claw portion of the gear B 盥 gear C is engaged with the gear: the wheel starts to rotate. The inclination of the inner teeth 36 and the inner teeth 36 are in a state in which the claws 4 are unremovable, so that the gears are in contact with each other.

The body, the gear B and the gear C rotate simultaneously. Further, the claw portion 41 of the C- is engaged with the gear "also in the state of the gear C", and the tooth portion of the gear c is in the form of "::" (the figure of Fig. 4 (1) is formed in the same manner as the tooth portion of the gear w - Phase 319228 14 1326100 « In addition, the gear of the large-diameter gear plate 37 of the gear C of the main gear 5, in the foregoing, is the same diameter as the gear A, and has the same position at the position of the gear eight. The tooth portion 34b, however, may be a toothless portion or a full tooth portion. The gear B is sandwiched between the gears A and the small gear 38 of the gear c. When the gear A and the gear c are not engaged with each other, the gear a can be freely rotatable with respect to the gear a and the gear c. At this time, the intermediate gear 33 can be engaged with the gear A of the main gear 5 and the gear B. However, it is of course not engaged with the gear c. Further, although the small-diameter circular plate 38 is provided in the gear c of the main gear 5, even the small-diameter circular plate 38 having the groove 39 and the claw 41 is attached and fixed to the gear A. It is also possible to perform the same action. Referring to Fig. 1, an inter-tooth gear 33 composed of a large-diameter gear 42 and a small-diameter gear 43_body, Engaged with the output gear 16, the main gear 5 meshes with the gear A, the gear b, and the reel c, and the intermediate gear 33 is cut by the gearless portion of the gear A and the gear c after the end of the closing of the elastomeric energy storage. The power transmission from the gear A and the gear C is transmitted. Therefore, after the energy is turned on: after the energy storage is completed, the intermediate gear 33 will be separated from the gear A of the main gear 5, and the energy storage motor 3 The driving force cannot be transmitted to the teeth of the main gear 5 = the distance from the gear C. The intermediate gear 33 that prevents the excess energy storage two" output gears from being engaged has: a one-way distance in the hole penetrating the axial center portion Person's, temple; will 浐屮I Ling with - (anti-reverse mechanism) 18. Not only =, the intermediate gear 33 of the transmission of the wheel 16 is the main gear 5, and the other side is also prevented by the main gear 5 side = up = outside 'Can also be used in the wheel of the wheel 16 - the two shells: 319228 15 1326100 u, the one-way clutch that allows one-way rotation (reverse anti-reverse to the valley end of the one-way coupling 18 allowed)辘, Qiao '丨 止 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 由 逆 逆 逆 逆 逆 逆 逆 逆 逆 逆 逆 《 逆 逆 逆The operation diagram of the energy storage mechanism of the switching means of 2, after the yn-period (4), (b), and in the sixth figure (4), (8), and (c), all of the graphs of Figure 5 are rotated. In addition, Figure 5 The second ... wheel shows the direction of rotation of the gear. Fig. 5 (4) shows the driving force of the window wheel 16 in the middle of the energy storage. The main gear 5 is connected to the gear A of the main gear 5 and the main gear 5 via the intermediate gear 33. The gear b bites:, = the wheel 5 rotates, presses the crankshaft portion, and the closing spring 22 starts to store energy. w is in the bottom dead center state of the main gear 5, and the two gears 33 are connected to the main return wheel 5 and the gear A. The missing tooth portion 34 is engaged in front. The state when the cyanine is completed. At this time, the gear A (four) (four) 34 of the intermediate gear 33 w wheel 5 is released, so that the engagement of the intermediate gear μ ” gear Α is released, the driving force of the output gear 16 is not transmitted to the gear, and the inertial force of the animal motor is not transmitted to Gear eight two ': state, by the limit ... limit the rotation of the gear A. Even if the wire A is in a restricted state, because the middle # wheel 3 = gear B bite, it can still be used by f motor The inertia wheel δ is slightly rotated. 1 history ω

At this time, the spring force of the closing spring 22 acts on the gear Τ of the main gear 1 and the gear Τ of the main gear 5 by the pressing lever gear Α. In this way, the 'claw 41 will rotate with the direction of the gear A 319228 16 to start the toothing. When the gear B is out of the 3S, the inner 3 3 card is engaged (the end is engaged), the gear B is the gear 1 phase. The tooth phase with the gear A is formed so that it starts to rotate with the gear B. Since the intermediate gear 33 is originally deprived (four), the phase of the external gear of the gear B, the 丨, U and the gear A) of the missing tooth portion and the intermediate gear 33 can be mutually touched. r ^ J smoothly re-bites and rotates in the back (nine) system display. Fig. 6 Turn on the spring 22 = ° in the figure 6 (8) 'The white arrow shows this direction. As described above, the small-diameter gear 43 of the gear 33 can be rotated by the action of the closing cam 6 that rotates with the main two of the main spurs 5, but the small-diameter gear 43 of the gear 33 also rotates, but 43 is produced. The Lit part is provided with a one-way clutch, so the small-diameter gear/generates the king turn, and the large-diameter gear of the intermediate gear 33 "the disk 16 stops rotating.", the return-out wheel = the main tooth generated by the discharge of the spring 22 The inertia of the rotating service body exceeds the predetermined rotation position (top dead center) for continuous rotation: the energy storage of the upper and lower Μ ,, the main gear 5 and the main shaft 1 will be reversed after the point is exceeded. However, the reversal force will be The rotational position set in the middle gate to exceed the above top dead center will be limited to the = state. In addition, in the _, upper; two display::: the wheel 5 will produce a reverse direction 'and the lower reverse arrow: The energizing direction of the spring 22 is not turned on. When the I"·Beicheng is turned on, when the energy storage of the spring 22 is started again, the middle turnback has been engaged with the wheel A and the gear b of the main chisel wheel 5, Therefore, the driving force of the output 319228 17 gear 16 will be turned on by the middle A and the gear B. When the gear 33 is transmitted to the gear of the main gear 5, the IS:: configured f-force mechanism 'clears the gear A and the intermediate gear 33 at the nip portion 34 where the closing spring 22 completes the energy storage, which can be corrected by the positional deviation required. The time does not need to be high; the month and the early structure between the pieces to carry out the power transmission. During the turning-on of the contact of the switching means, as the gear Α rotates, the claw portion 41 will start to engage with the internal tooth % of the gear B. When engaged, the outer 35 of the gingival B will phase with the gear A. The tooth phases are formed in unison so that the gear B and the gear A start to rotate at the same time. Since the intermediate gear (4) is originally engaged with the external teeth 35 of the gear B, the gear A (exceeding the # wheel A of the missing tooth portion) which coincides with the tooth position other than the gear B can be smoothly bitten and merged with the intermediate gear. Rotate.
