In the wave of industrial automation, robots play an increasingly important role. The performance of robots largely depends on their internal core components. This article will provide a detailed introduction to these key components to help you better understand the working principles of industrial robots.
The main core components used in industrial robots include servo motors, harmonic reducers, RV reducers, and planetary reducers. Next, we will introduce their respective characteristics.
servo motor
Servo motors are the "power heart" of industrial robots, serving as the driving source for their movements. They are responsible for converting electrical energy into mechanical energy, enabling the robot to perform various actions and accurately control its movements. The main characteristics of servo motors include:
Precise control: Achieving closed-loop control of position, speed, and torque to ensure the accuracy of robot actions.
High speed performance: Generally, the rated speed can reach 1500-3000 revolutions per minute, making the robot move quickly.
Anti overload capability: able to withstand momentary high loads, adapt to rapid start-up and load fluctuations.
Low speed stability: It can maintain stability even when running at low speeds, suitable for situations that require precise operation.
Fast response: The dynamic response time of motor acceleration and deceleration is short, usually within a few tens of milliseconds, which improves the work efficiency of the robot.
Low noise and heat generation: Low noise and heat generation during operation help the robot work stably for a long time.
Harmonic Drive
Harmonic reducer is one of the key components for achieving precise robot movements. It is a transmission device used to reduce speed and increase output torque, and is commonly used in situations that require high precision and high rigidity. It amplifies the output torque of the motor by increasing the transmission ratio. Its main features include:
Large transmission speed ratio: The speed ratio range of single-stage harmonic gear transmission is 70~320, meeting different precision requirements.
High load-bearing capacity: The structure has strong rigidity and can bear large loads.
High precision transmission: small transmission error, no backlash meshing, ensuring transmission accuracy.
High efficiency: High transmission efficiency, smooth movement, efficiency can reach 69%~96%.
Simple structure: fewer parts, easy to install and maintain.
Small size and light weight: easy to integrate into the compact space of robots.
RV reducer
RV reducer is also a device used for reducing speed and increasing torque, with high rigidity, high precision, and high load-bearing capacity. It can withstand large impact loads and frequent starting and stopping. With its compact structure and efficient performance, it is widely used in industrial robots. Its main features include:
Compact and lightweight: small in size, light in weight, and easy to integrate.
Good heat dissipation: Good heat exchange performance, fast heat dissipation, ensuring long-term stable operation of the robot.
Easy installation: Easy to install, easy to maintain and repair.
High speed ratio and high torque: The transmission ratio is high, the torque is large, and it can withstand high overload capacity.
Smooth operation: Low noise, smooth operation, improves the working accuracy and lifespan of the robot.
Planetary reducer
Planetary reducers are used to reduce speed and increase torque through the meshing of multiple planetary gears, and are favored for their high efficiency and rigidity. They are important components for achieving precise robot movements. Its main features include:
Smooth operation: Smooth operation, low noise, providing a comfortable working environment.
High rigidity: Strong structural rigidity, high load-bearing capacity, and extended service life.
High precision: The transmission accuracy is high, and a single stage can achieve within 1 point, meeting the requirements of high precision.
High efficiency: High transmission efficiency, with a single-stage range of 97% -98%, reducing energy loss.
Simple structure: fewer parts, easy installation, and reduced maintenance difficulty.
Small size and light weight: easy to integrate, reducing the overall weight of the robot.
These core components work together to enable industrial robots to achieve high-precision, high-speed, and highly reliable motion control, meeting various needs of modern industrial automation.
