Electrolytic capacitor is a kind of solid electrolytic capacitor with high impedance and high frequency anti ripple current. It is used in high frequency circuits such as digital circuit and computer motherboard, and seeks thiophene electrolyte system and related polymerization synthesis technology. Two pairs of small teeth gears, each driven by an eccentric shaft. The gear on the driving side is driven by the motor to rotate, and the eccentric shaft drives the eccentric shaft on the driven side to rotate through the connecting rod to make the two pairs of gears move synchronously. The model wheels of two pairs of teeth muffler are fixed through three holes on the outer gear plate. Three holes are required to be in a circle with the center of the gear as the center of the muffler leakage, and the three holes are on the same surface. The gear needs to ensure smooth and even friction in the process of movement, gear processing needs to ensure that the tooth surface is smooth, each tooth is full. Technical parameter requirements: gear processing needs to ensure the parameter requirements of each gear tooth. The parts are carburized after processing. Ensure the surface hardness of the gear. Main parameters: technical parameter requirements: gear processing needs to ensure the gear tooth surface parameter requirements. The parts are carburized after processing. Ensure the surface hardness of the gear.
