What is the drive system of robot? The drive system of a robot is a kind of gear drive equipment that is widely used. It features a small size, high transmission efficiency, wide scope of speed, and high precision. The robot planetary gearbox can be integrated with the servo motor, stepper motor, or DC motor for use. As for the single-stage transmission of planetary gear motor, owing to the structure, it ranges from 2.8 to 12.5. The common gear ratio is 3/4/5/6/8/10. The stages of robot planetary gearboxes generally don’t exceed 3-stage, but some customized gearboxes with large gear ratios have 4-stage transmission. Compared with other types of gear motors, planetary gear motors have the characteristics of high rigidity, high precision (single-stage: possible to achieve within 1 arcmin), high transmission efficiency (single-stage: 97-98%), high torque/volume ratio, free lifetime maintenance and so on.
Robot planetary gearbox with motor is an essential part. It differs from those used in conventional automation equipment. In general, robots will perform repetitive actions in their work, so it puts forward high requirements for positioning as well as repetitive position accuracy. Also, compared with large automation equipment, the robots, especially light-duty robots have a smaller size, lighter weight. Therefore, as parts, the planetary gear motor should also meet the requirements of lightweight. At present, the reducers used in the robots mainly include planetary gear motor (intelligent robot), harmonic gear motor, and RV gear motor (robot joint). As the name implies, planets revolve around stars. The planetary gearbox has three planet wheels revolving around a sun wheel. The robot planetary gearbox is small in size, light in weight, high in carrying capacity, long in service life, stable in operation, and low in noise. It has the characteristics of power splitting and multi-tooth meshing, which is widely used in the industry.
