Gear rotation is the most widely used and common transmission form in mechanical transmission. The gear uses its teeth to transmit torque and motion, change the direction of motion, indicate the reading and change the position of the mechanism.
The manufacturing materials and heat treatment process of gears have a great influence on the bearing capacity, size and weight of gears. Before the 1950s, gears were made of carbon steel. In the 1960s, alloy steel was used, while in the 1970s, surface hardened steel was used. According to the hardness, the tooth surface can be divided into soft tooth surface and hard tooth surface. Customized gears, industrial transmission parts of various specifications Gear refers to a mechanical element with gears on the rim continuously engaging to transmit motion and power, and it is a wheel like mechanical part that relies on the engagement of teeth to transmit torque. The gear can be driven with other toothed mechanical parts (such as another gear, rack, worm) to change the speed and torque, change the direction of movement and change the form of movement. Because of the advantages of high transmission efficiency, accurate transmission ratio and large power range, gear mechanisms are widely used in industrial products. Their design and manufacturing level directly affect the quality of industrial products. The gear teeth clasp each other, and the gear will drive another gear to rotate to transmit power. To separate the two gears, chains, tracks and belts can also be used to drive the gears on both sides to transmit power.
