Robots are mainly divided into four categories: industrial robots, collaborative robots, service robots and special robots. The first two types of robots are mainly used in industrial production, and the third type of robots are generally not used in manufacturing, but are mainly used in the service industry. Collaborative robots cooperate with workers in industrial production, so they are independent of the industrial robot category. Harmonic robot speed reducer is widely used in industrial robots and collaborative robots.
Harmonic robot speed reducer can be divided into general-purpose, special-purpose and precision reducers, among which precision harmonic robot reducers are mainly used in the robot industry. ①Harmonic drive robot universal reducer: generally refers to robot harmonic drive, worm turbine reducer and robotic gearbox reducer, mainly small and medium-sized, which are widely used in various industries; ②Harmonic drive robot special reducer: generally large and extra large, mostly dedicated to the industry Reducer, such as automobile reducer, photovoltaic reducer, wind power reducer; ③Harmonic drive robot precision reducer: mainly micro and small, generally refers to RV reducer or china harmonic reducer, widely used in industrial robots, machine tools, semiconductors, aviation High-precision scenarios such as aerospace are especially widely used in articulated robots.
Motor Input:
The process of harmonic drive robot arm gearbox begins with the motor generating high-speed, low-torque rotational energy, typically electrically powered.
Gear Reduction:
The robotic gearbox consists of a set of gears arranged in specific ratios, employing gear reduction principles. This reduces the speed of the motor output while increasing torque.
Planetary Gear Arrangement:
Many reductor harmonic drive robot arm gearboxes incorporate robot planetary gearbox arrangements, providing a compact and efficient solution for gear reduction. Planetary gears rotate around a central sun gear, contributing to the overall reduction.
Increased Torque at Output Shaft:
As the gears mesh, the mechanical advantage gained through reduction results in a significant increase in torque at the output shaft of the robotic gearbox.
Transmission to Robot Arm Joints:
The transformed output from the robot planetary gearbox, characterized by lower speed and higher torque, is transmitted to the joints of the robot arm.
Precise and Controlled Movement:
The role of this harmonic gearbox is crucial in providing the necessary torque for precise and controlled movement of the harmonic drive robot arm, allowing it to perform various tasks accurately and efficiently in industrial, manufacturing, or research settings.
Among the precision harmonic drive robot arm reducers, compared with the RV reducer, the harmonic gear drive reducer has a simpler structure, smaller mass and volume, higher single-stage transmission ratio and higher precision, and harmonic drives in robotics has an irreplaceable position in the field of robotics. RV reducer: It has a large transmission ratio range, relatively stable precision, high fatigue strength, and higher rigidity and torque bearing capacity. It has advantages in heavy-load parts such as robot arms and machine bases. Due to the characteristics of large external dimensions, it cannot be developed into the light and flexible light load field.
Harmonic drive robot reducer: The harmonic robot speed reducer has the advantages of large single-stage transmission ratio, small volume, small mass, high motion precision, and can work normally in confined space and medium radiation conditions. Compared with the general reducer, when the output torque is the same, the volume of the harmonic drive oldham coupling reducer can be reduced by 2/3 and the weight can be reduced by 1/2, which makes it light and flexible in the robot forearm, wrist, hand, etc. Taller components have irreplaceable advantages.
The application field of robot harmonic drive reducer is currently dominated by various robots, in addition to CNC machine tools, semiconductor, photovoltaic, medical and other equipment fields.
Harmonic Drive: Known for high precision, robot harmonic drives use a flexible spline that is deformed by an elliptical wave generator, resulting in highly accurate rotational motion.
Planetary Gear: Common in various applications, planetary gears consist of a central sun gear, multiple planet gears, and an outer ring gear, providing high torque and compact size.
Harmonic Drive: Utilizes three main components: a circular spline, a flexible spline, and a wave generator. The wave generator deforms the flexible spline to engage with the circular spline, creating smooth, precise motion.
Planetary Gear: Features a sun gear at the center, robot planetary gearboxes around the sun gear, and a ring gear that encompasses the planet gears. The planet gears rotate around the sun gear while meshing with the ring gear.
Harmonic Drive: Harmonic drives in robotics offer high precision with minimal backlash, making it ideal for applications requiring exact positioning, such as robotics and aerospace.
Planetary Gear: Known for high torque transmission and efficiency, planetary gears are widely used in automotive, industrial machinery, and renewable energy applications.
Robot harmonic drive has extensive applications in harmonic robot arm gearboxes, particularly in the field of robotic arms. Harmonic drive robot arms utilize these drives for their compact size, high precision, and efficient power transmission. By incorporating harmonic robotic gearbox drives into robot arm gearboxes, precise and smooth motion control can be achieved, allowing for accurate positioning and manipulation of objects. Harmonic drives in robotics offer advantages over traditional planetary gear robot arm systems, such as reduced backlash and improved torque-to-weight ratio, making them ideal for high-performance robot arm applications. Their compact design and superior performance make harmonic drive robot arms well-suited for various industries, including manufacturing, automation, and research.
