FAQ
Q:Key points of selection of planetary reducer
A:1. Frame number determined by torque: the power source will have the effect of torque amplification after deceleration ratio. The output torque value of the reducer is proportional to the deceleration ratio, and the larger the ratio, the higher the torque value will be; But the gear group of the reducer has the limit, so the rated output torque of the planetary reducer is to say that the product can work stably under the data operation, so the box number must be selected according to the demand torque.
2, according to the accuracy to determine the model: in the process of automation will need positioning, when the positioning accuracy requirements are higher, you need to choose a higher level of products, and vice versa. The precision of the planetary reducer is called the "backgap", which refers to the gap of the gear group. The definition is the Angle value that the output shaft of the planetary reducer can rotate when the input end is fixed. The smaller the return clearance is, the higher the accuracy is and the higher the cost is. The user can choose the right accuracy according to their actual situation.
3, according to the installation size selection: that is, the size of the front end of the servo motor. The input end of the planetary reducer must match the output end of the servo motor.
4, according to the appearance selection: according to customer demand output shaft and connecting surface has a standard series for users to choose, can also be customized according to user special needs.
5, according to the axial and radial force selection: the life of the planetary reducer is affected by the internal bearing, bearing life can be calculated through the load and speed, when the axial and radial force load of the reducer is higher, the bearing life will be shortened, at this time it is recommended to choose a large product.

Handling Sudden Changes in Direction and Speed with Servo Gearboxes
Servo gearboxes are designed to handle sudden changes in direction and speed effectively, ensuring precise motion control even during dynamic operations. They employ several mechanisms to address these challenges:
1. Acceleration and Deceleration Profiles: Servo systems can be programmed with specific acceleration and deceleration profiles. This means that when a sudden change in speed or direction is commanded, the system can ramp up or down the speed smoothly, reducing the impact of sudden changes on the mechanical components.
2. Closed-Loop Control: Servo systems operate in a closed-loop configuration, where feedback sensors continuously monitor the actual position and speed of the system. When a sudden change is commanded, the controller can make real-time adjustments to ensure the system reaches the desired position accurately and smoothly.
3. Torque Control: Servo gearboxes are designed to provide high torque output even at low speeds. This is crucial for handling sudden changes in direction and speed, as the gearbox can deliver the required torque to quickly accelerate or decelerate the load.
4. Dynamic Response: Servo systems have fast dynamic response capabilities, which means they can quickly adapt to changes in input commands. This responsiveness allows the system to handle sudden changes in direction and speed without sacrificing accuracy or stability.
5. Electronic Damping: Some advanced servo systems incorporate electronic damping mechanisms that can be adjusted based on the application's requirements. This feature helps dampen vibrations and oscillations that may occur during sudden changes in motion.
6. Overcurrent and Overvoltage Protection: Servo systems are equipped with protection mechanisms that detect excessive currents or voltages. If a sudden change in direction or speed causes abnormal loads or voltages, the system can take corrective actions to prevent damage.
Overall, servo gearboxes excel in handling sudden changes in direction and speed by leveraging their closed-loop control, high torque output, and fast dynamic response capabilities. These features allow them to provide accurate and reliable motion control in dynamic and rapidly changing operating conditions.
Considerations for Selecting the Right Servo Gearbox for an Application
Choosing the appropriate servo gearbox for a specific application requires careful evaluation of several key factors:
1. Torque and Speed Requirements: Determine the required torque and speed characteristics of the application, ensuring that the chosen servo gearbox can provide the necessary output.

6. Load Distribution: Analyze how the load will be distributed among the gears to prevent excessive wear and ensure optimal performance.
7. Backlash and Compliance: Consider the application's tolerance for backlash and compliance. Choose a servo gearbox with low backlash if precise positioning is essential.
8. Environmental Conditions: Factor in the environmental conditions of the application, such as temperature, humidity, and exposure to contaminants. Choose a servo gearbox with suitable sealing and protection.
9. Lubrication: Determine the lubrication requirements of the gearbox and select a model that aligns with the application's maintenance practices.
10. Overload and Shock: Consider potential overload and shock conditions the gearbox may experience. Choose a servo gearbox that can handle sudden changes in load without compromising performance.
11. Feedback Devices: If precise motion control is required, choose a servo gearbox that is compatible with the desired feedback devices, such as encoders or resolvers.
12. Efficiency: Evaluate the efficiency of the servo gearbox to ensure that it contributes to the overall energy efficiency of the system.
13. Service and Support: Select a reputable manufacturer that offers reliable technical support, documentation, and post-purchase services.
14. Budget: Balance the performance requirements of the application with the available budget to make an informed decision.
