Application and Selection of the collaborative innovative combination of servo motors and planetary reducers

1. Application scenarios

1. Industrial automation

Industrial automation requires high-precision, high-speed and high-torque motion control. For example, in patch robots in the electronics manufacturing industry, servo motors provide precise position and speed control, while planetary reducers increase torque, allowing robots to pick and place tiny electronic components quickly and accurately. The placement robot of an electronics factory adopts this combination, which significantly improves production efficiency and placement accuracy, and reduces the defective rate.

2. CNC machine tools

CNC machine tools require precise axis movements and powerful cutting forces during machining. The servo motor ensures the precise positioning of the coordinate axis, and the planetary reducer converts the high-speed rotation of the motor into low-speed and high-torque output suitable for cutting. On a CNC milling machine in a mold processing factory, this combination enables the machine tool to maintain stable cutting performance when processing complex molds, improving the processing accuracy and surface quality of the molds.

3. Automated logistics and warehousing

In automated three-dimensional warehouses, the operation of stackers requires rapid positioning and carrying of heavy objects. The servo motor and the planetary reducer work together to realize the rapid shuttle of the stacker between the shelves and the accurate picking and placing of goods. The logistics center of a large e-commerce company uses this combination of stackers, which greatly improves the efficiency and accuracy of warehousing and logistics.

2. SelectionKey points

1. Torque and speed requirements

Choose the appropriate model according to the load characteristics and movement speed requirements of the application scenario. For example, in a heavy-duty handling robot, factors such as the weight, friction, and acceleration of the handling object need to be calculated to determine the required torque and speed, so as to select a servo motor and matching planetary reducer that can provide sufficient power.

2. Accuracy and return clearance

For high-precision applications, such as CNC machine tools and precision measuring equipment, it is necessary to select a planetary reducer with high precision and small return clearance to ensure the accuracy of movement. A certain precision machining workshop paid special attention to the accuracy index of the planetary reducer when building its CNC lathe Selection to meet the requirements for processing high-precision parts.

3. Installation space and size restrictions

Consider the structure and installation space of the equipment and select the servo motor and planetary reducer of appropriate size. In an automated production line with a tight space, it is necessary to choose a small but powerful combination to fit in the limited installation space.

4.Working environment

If the working environment is harsh, such as high temperature, humidity, dust, etc., you need to choose products with corresponding protection levels and adaptability. In the automation equipment of a foundry, due to the high ambient temperature and large amount of dust, high temperature-resistant and dust-proof servo motors and planetary reducers were selected.

Example: An auto parts manufacturer designed its new automated production line Selection. The production line includes handling robots, processing machine tools and material handling systems. In the handling robot part, after analyzing the load (weight and shape of automobile parts), motion trajectory and speed, a servo motor with larger torque was selected, and paired with a planetary reducer with appropriate reduction ratio and high precision. , to achieve fast and accurate parts handling. For the processing machine tools, according to the cutting force and precision required by the processing technology, high-power servo motors and low return clearance planetary reducers are selected to ensure the processing quality of the parts. In the material conveying system, taking into account space constraints and operating speed, a combination of servo motor and planetary reducer with compact size and moderate speed was selected.
