Precision transmission gears play a variety of important roles in mechanical equipment, mainly including the following aspects:
Transmitting power and motion: The most basic function of gears is to transmit power and rotational motion. Through two or more meshing gears, the power and motion of one gear can be transmitted to another gear, thereby driving the work of the entire mechanical system.
Change the rotation speed and torque: Through the combination of gears of different sizes, the increase and decrease of rotation speed and the conversion of torque can be achieved. Large gears drive small gears to increase speed and reduce torque, while small gears drive large gears to reduce speed and increase torque. This feature is particularly important in mechanical equipment that requires speed or torque change.
Change the direction of rotation: By designing the tooth shape and installation method of the gears, the direction of rotation can be changed. For example, two meshing helical gears or herringbone gears can reverse the rotation direction of the input shaft on the output shaft.
Realize long-distance transmission: In some mechanical equipment, long-distance transmission is required due to spatial layout or work requirements. Gear transmission can achieve remote transmission of power through the combination of an intermediate shaft and multiple gears.
Smooth transmission and buffering vibration reduction: Gear transmission has the characteristics of good smoothness, because the meshing between gear teeth can share the load and reduce the impact. In addition, by designing the tooth shape and material of the gear, the effect of buffering vibration reduction can be achieved to protect the mechanical equipment from damage.
Precise transmission: Gear transmission has high transmission accuracy and can achieve precise speed ratio and position control. This is especially important in mechanical equipment that requires high-precision transmission, such as precision machine tools, measuring instruments, etc.
Realize multiple forms of motion: Through complex gear combinations and mechanism designs, a variety of complex forms of motion can be achieved, such as indexing motion, intermittent motion, etc. This makes gear transmission widely used in automation equipment and complex mechanical systems.
