Thereby, the speed of the passive disk 26 is increased, and the passive shaft 25 is driven by the clutch 27 to drive the rear wheel (not shown) to accelerate the speed, thereby increasing the traveling speed of the vehicle. On the contrary, when the throttle is released, the centrifugal force of the ball 24 is reduced, and the pressing of the transmission belt 28 is combined, so that the distance between the surface 2 2 and the collar 2 is increased, and the transmission belt 28 is The range of circumferential rotation will be reduced, so the speed of the passive disk 26 will also decrease. 'The rear wheel ride will be reduced by the speed of her 25 to reduce the speed, and the speed of the vehicle will be slowed down. Please cooperate with Figure 1 >, the tongue plug 14 is connected by the connecting rod 15 and the crankshaft 13 in the crankcase 1 2, where the piston! 4 When driven by the power of oil and gas explosion, it is a reciprocating motion. In order to reciprocate the piston i 4, the circular motion of the Wei crankshaft 13 is used, so that the connection between the connecting rod 15 and the crankshaft 13 is utilized by the weight. The work of the 3 workers makes it a link of the -34 type. When the oil and gas blasts and pushes the play 4, the play 4 will push, and the link 1 5 pushes the weight i 3 i of the crankshaft i 3, Further, the crankshaft 丄3 can be made to move in a circular motion. However, in this way of operation, the weight of the counterweight 3 is due to the fact that the crankshaft 13 will vibrate when it is actuated, and the vibration will increase synchronously with the increase of the crankshaft actuation speed, so in order to make the crankshaft i The operation of '3 can be - steady off state' is established in the crankshaft i 3 (4) and the balance shaft 3, using the drive gear 132 set on the curve, the wheel is set on the Na 3 cut copper wheel 32 mutual price M295211, 1 The crankshaft 13 drives the balance shaft 3 to rotate together via the drive gear χ 3 2 and the driven gear 3 2, so that the crankshaft 13 is connected to the piston i 4 and the connecting rod! When the belt is actuated, it can effectively eliminate the lack of vibration caused by the inertia force of the weighting block i 3 of the crankshaft 13. The establishment of the balance shaft 3 can eliminate the lack of vibration of the crankshaft 13, but due to the crankshaft i 3 The center of gravity of the counterweight block 131 must correspond to the center of gravity of the counterweight 3 of the balance shaft 3 to achieve the purpose of reducing the inertia force and reducing the vibration, so that the components of the crankshaft i 3 and the balance shaft 3 are performed. , the attention of the Saki people and the inconsistency of the deviation, which causes the inconvenience of the assembly and the lengthening of the time. The conventional method for solving the assembly of the crankshaft i 3 and the balance shaft 3 is as shown in FIG. 3, and is mainly pre-engaged on the end I of the outer periphery of the center of gravity of the drive gear i 3 2 of the crankshaft 3 The positive symbol i 3 2 i, similarly, a pair of positive marks 3 2 丄 are also preliminarily placed on the outer end surface of the driven gear 3 2 of the balance shaft 3, and when the money is assembled, the drive _ wheel 1 3 2 alignment mark! 3 2 ! is aligned with the alignment _ 3 21 of the driven gear 3 2, and the drive gear 13 2 of the crankshaft 13 and the driven gear 3 2 of the balance shaft 3 are mutually aged, so that the crankshaft i 3 can be matched The details of the i 3 χ are in the corresponding state with the center of gravity of the weight 31 of the balance shaft 3, that is, the combination of the crankshaft 3 and the balance shaft 3 can be made to the correct state. However, on some special occasions, as shown in the fourth, in order to meet the special requirements of the engine 1, the bearing χ 3 3 on the crankshaft 13 will be sighed to be larger than the outer diameter of the drive gear 丄3 2 The right-handed tiger 13 21 that drives the wheeled worker will be obscured by the bearing 丄3 3, and cannot easily perform the same action as the aligning mark 3 21 of the driven tooth 2. Therefore, how to solve the problem that the crankshaft 13 and the balance shaft 3 can be assembled smoothly and correctly in the above two people is actually a problem that requires force, and force M295211.
