Gear transmission refers to a device that transmits motion and power by a gear pair. It is the most widely used mechanical transmission method in various modern equipment. It has relatively accurate transmission, high efficiency, compact structure, reliable work and long life. Gear transmission is the most widely used transmission form in mechanical transmission. It has relatively accurate transmission, high efficiency, compact structure, reliable work and long life. At present, the achievable indicators of gear technology: peripheral speed v=300 meters per second, rotation speed n=105 revolutions per minute, transmitted power P=105 kilowatts, modulus m=0.004~100 mm, diameter d=1 mm~152.3 mm . Gear transmission refers to a device that uses the teeth of the main and driven wheels to directly transmit movement and power. Gear transmission is a mechanical transmission that uses the gear teeth of two gears to mesh with each other to transmit power and movement. Gear transmission can also refer to a device in which the teeth of the driving and driven wheels directly transmit movement and power. Among all mechanical transmissions, gear transmission is the most widely used and can be used to transmit motion and power between two shafts that are not far away from each other. The characteristics of gear transmission are: smooth gear transmission, precise transmission ratio, reliable operation, high efficiency, long life, and a wide range of power, speed and size. For example, the transmission power can be as small as hundreds of thousands of kilowatts; the speed can reach up to 300 meters per second; the gear diameter can be from a few millimeters to more than 20 meters. However, special equipment is required to manufacture gears, and meshing transmission will produce noise. When the total displacement coefficient of a pair of gears is greater than 0, it is a positive transmission. Positive transmission means that the gear uses a positive displacement design. If two gears that mesh with each other are in positive displacement, then their center distance is greater than (the pair of gears) the standard center distance. On the contrary, if both gears use negative displacement, the center distance is smaller than the standard center distance. To judge whether the position is changed, it is mainly to compare the measured gear parameters (including the center distance) with the parameters of the gear standard, and then a conclusion can be drawn.
