New Description: [New Technology Area] This creation is about an engine damping and noise reduction mechanism, especially a structure that reduces the noise generated when the engine crankshaft and the main shaft are actuated. [Prior Art] As for the structure of the engine 1 & 'eyes, see Fig. 1, which is provided with a transmission case 2 on the side of the engine 1, and a belt shifting mechanism 3 is provided in the transmission case 2 when mixing gasoline and air After the oil and gas is input into the engine 1, the ignition of the ignition device 11 causes the oil and gas to ignite, and the piston 12 is reciprocated to drive the crankshaft 丄3, and the crankshaft 13 extends to the inside of the transmission case 2 with the shaft 14 The shifting mechanism 3 is connected to the company, and the belt shifting mechanism 3 drives the rotation of the rear wheel. The rear wheel then drives the front wheel synchronously to achieve the purpose of traveling. Please also refer to Figure 2, the piston i 2 is connected with the crankshaft 丄3 by the joint 5, and when the piston 12 is pushed by the oil and gas explosion, it is - reciprocating to make the reciprocating motion of the piston i 2 into the crankshaft i 3_week movement, so the rod 15 and the crankshaft i 3 are designed by the weight i 6 , and for an eccentric type, when the piston 12 is pushed by the oil and gas explosion, the piston 2 is connected by the connecting rod 15 Pushing to W 3's Saki 41, and allowing her to move in a circular motion, but the force of the time will be 配3's match with Wei Wei 6 and cause the crankshaft 13 to vibrate when it is actuated. Then, a damper gear 41 is provided to align with the chord, and the side is stationed on the side, and the (4) group is corrected by the minus 3.

Drive and twirling - small angle 'When the sub-gear 7 2 2 rotates - small ,, ie: just aligned with the main gear 721, the drive gear on the crankshaft 7 will drive the main, _ wheels 721, 72 2 Rotating, which in turn drives the main ^ 9 M354526 for synchronous rotation, can also effectively solve the problem of two-wire 嗓 。. In addition, as shown in the other examples, the shock absorbing gear 9 includes a center block 91, a passive gear Μ, a 稽 片 93, and plural The elastic member 94 is provided with a flange seat 9 1 1 in the center of the center block 91. The inner circumference of the worker is covered with a tooth groove 9 1 2, and a plurality of seats 9 11 are provided. a stud 9 i 3 , which can be used to project a spring member 9 4 to provide a 'the towel-turning member 9 4 to be elastic with a rubber to implement the 'the center of the driven gear 9 2 There is a sleeve seat g 2 χ, the sleeve seat 9 21 can be sleeved with the flange seat 911, and a plurality of holes are arranged around the sleeve hole seat 9 2 corresponding to the center block 9 i The through hole 9 2 2 is for receiving the mixed tree 9 4 , wherein the 9 3 is an annular plate body, and a through hole 9 3 is formed in the center of the blade 9 3 The through hole g 3 1 can make the blocking piece 9 3 flat on the surface of the _ wheel 9 2 , and the 9 3 is provided with a plurality of H1 fixed holes 9 3 2 ' fixed holes 9 3 2 for combination The element 8 i 5 is passed through the yoke and the center block 91 is combined with the driven gear 92, whereby When the power is output from the scissor gear 7 2 of the crankshaft 7 to the driven gear 92 of the damper gear 9, by the damping effect of the elastic member 94, the squeezing force of the scissor gear 7 2 can be buffered and then Through the center block 91, the power is transmitted to the main shaft 8, thereby effectively avoiding the wear of the gear surface and achieving the effect of eliminating the backlash and the running noise. The above-mentioned mechanism has indeed been achieved. The purpose and effect of the appeal should have met the requirements of novelty, progress and practicality. Please propose a new type of patent in accordance with the law. Please ask the examiner for the detailed examination and grant the approval of the new patent i M354526.
