Duplex gear is a common gear transmission device. Its design and structural characteristics are as follows:
1. Basic structure: The duplex gear consists of two gear components, one of which is the driving gear and the other is the driven gear. The driving gear is driven by a power source (such as an electric motor), and the driven gear receives power through gear transmission and completes the corresponding work. The driving gear and the driven gear rotate through meshing teeth.
2. Gear module: The design of duplex gears requires determining the appropriate gear module based on the transmission ratio and working load. Gear module is an important parameter of gear size, which can affect the transmission efficiency and load-bearing capacity of duplex gears.
3. Number of teeth and meshing conditions: The number of teeth of the Duplex gear must meet the meshing conditions of the gear transmission, including gear module, meshing angle, center distance and other parameters. Reasonable selection of the number of teeth and meeting the meshing conditions can ensure the smoothness and efficiency of gear transmission.
4. Accuracy and tolerance: The manufacturing and processing accuracy of duplex gears is high, and the accuracy of the gear's pitch, meshing angle, tooth shape and other parameters needs to be ensured. For high-precision double gears, professional gear processing equipment and technology are usually required to ensure good performance of the gear fit.
5. Surface treatment: The surface of duplex gears usually requires hardening, grinding and other treatments to improve the hardness, wear resistance and transmission efficiency of the gears. Common surface treatment methods include quenching, chrome plating, grinding, etc.
6. Lubrication and noise control: In double gear transmission, the selection and use of lubricating oil are crucial to the life and operating stability of the gear transmission. Proper lubrication can reduce friction and wear of gears and reduce transmission noise.
It should be noted that when designing and using duplex gears, selection and calculation should be carried out according to specific work requirements and transmission parameters to ensure the reliability, smoothness and efficiency of the gears. At the same time, regularly maintain and inspect the working condition of the double gears, and deal with gear wear and failure in a timely manner to extend the service life of the gears.
