Do you really understand precision planetary reducer?
In the reducer family, the planetary reducer has beautiful appearance, accurate positioning, economical and practical, high precision and large load-bearing capacity. It is suitable for the deceleration and rotation of various DC servo motors, AC servo motors and stepper motors. It is widely used in precision machine tools , automatic cutting equipment, metallurgical equipment, printing equipment, injection molding machine equipment, packaging equipment and other areas. Its function is to reduce the speed, increase the torque and reduce the load/motor inertia ratio on the premise of ensuring precision transmission. When the concentricity between the motor and the reducer is ensured very well during assembly, the motor output bearing only receives rotational force and the operation will be smooth.
The word planet of the planetary reducer comes from its gear layout. Since the gear of the planetary reducer is three small gears rotating around the large gear, we call this gear a planetary gear layout, so we call this planetary gear layout. The reducer is a planetary reducer. Planetary reducer classification There are two main types of precision planetary reducers according to the output direction: linear type and right-angle angle type according to the output mode; smooth straight shaft, straight shaft with key, keyhole output according to the connection method; circular flange connection, square Flange connection.
There are generally three types according to the levels: first-level deceleration (generally less than 10:1), second-level deceleration (generally greater than 10:1 and less than or equal to 100:1), and third-level deceleration (some brands do not have a third level. The reduction ratio should be 100:1, and the general classification principle is greater than 100:1) According to use: military and civilian; According to operating environment: standard environment, low temperature environment, clean room environment and vacuum According to accuracy: standard precision and high precision ; According to origin: domestic, imported, domestic assembly. The functions of the planetary reducer 1. Change the output speed (deceleration, speed increase or variable speed) of the power machine to suit the working needs of the working mechanism; 2. Change the torque output by the power machine to meet the requirements of the working mechanism; 3. Output the power machine The form of motion is converted into the form of motion required by the working mechanism (such as changing rotational motion into linear motion, or vice versa). 4. Transmit the mechanical energy of one power machine to several working mechanisms, or transfer the mechanical energy of several power machines to one working mechanism. 5. Other special functions, such as the use of mechanical reducer devices to facilitate assembly, installation, maintenance and safety of machines.
