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.
