1. Core function: decelerating, increasing torque, matching load
Servo motors usually have the characteristics of high speed and low torque, while cutting machines require low speed and high torque when cutting plates (especially thick plates or high-density plates). The servo planetary reducer converts the high-speed and low-torque force of the motor into the low-speed and high-torque output required by the equipment through the internal planetary gear transmission structure.
Torque amplification: According to the set reduction ratio, the output torque is multiplied, so that the system can easily cope with the huge resistance during cutting and solve the problem of "high speed and powerlessness" of the motor.
Speed matching: Reduce the high speed of the motor to the stable low speed required for the cutting process to ensure the smoothness of the cutting process.
2. Key guarantee: buffer impact and protect motor
The cutting process of the cutting machine is a typical heavy-load impact working condition. The moment the tool contacts the plate, a huge peak torque and impact load will be generated. If the motor is directly connected, these impacts will be directly transmitted to the precision encoder and bearings inside the motor, which can easily cause damage.
Impact buffering: The gear meshing structure of the reducer itself is a natural mechanical buffer, which can absorb and disperse the impact load at the cutting moment.
Overload protection: When the load suddenly changes or unexpected jamming occurs, the reducer can withstand and consume part of the energy first to avoid direct impact on the servo motor, thereby effectively protecting the core components of the motor and extending the service life of the entire drive system.
3. Precision support: stable transmission to ensure cutting quality
Heavy-duty cutting requires not only "power" but also "precision". The servo planetary reducer achieves low backlash and high rigidity through precise gear processing and assembly processes.
Precise positioning: Low backlash ensures that the instructions of the servo motor can be accurately executed, avoiding position deviations during frequent starts, stops and reversals, and ensuring the accuracy of cutting dimensions.
Stable operation: The high rigidity structure ensures the stability of the transmission system under heavy load and reduces jitter and vibration during operation, thus improving the flatness of the cutting surface and overall processing quality.
4. Selection and usage suggestions
In order to ensure that the servo planetary reducer effectively solves the torque bottleneck, please pay attention to the following when Selection and use:
Torque Selection margin: Calculate the continuous operating torque and peak torque of the load. The rated output torque at Selection should cover the continuous working conditions, and reserve at least 20% margin to cope with peak impact loads.
Pay attention to the backlash level: The cutting machine has requirements for cutting accuracy, and a precision-grade servo reducer with smaller backlash should be selected to ensure positioning accuracy.
Matching inertia: The reducer can reduce the inertia of the load converted to the motor shaft. It is recommended to control the ratio of the load inertia to the motor rotor inertia between 1:3 and 1:5 to obtain the best dynamic response and stability.
Regular maintenance: The dust environment of the cutting machine is harsh, so the reducer seals need to be checked regularly to prevent dust intrusion from causing lubrication failure and gear wear. At the same time, regular replacement of appropriate lubricating oil according to the number of operating hours is the key to ensuring long-term reliable operation.
