The robotic arm is the most widely used automated mechanical device in the field of robotics technology. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. The manipulator is used to complete the manufacturing operation; the reducer in the manipulator is one of the important components. At present, the reducer, planetary reducer, harmonic reducer, and DC reducer have been successfully developed and applied, and the harmonic drive gear reducer has been applied.
Harmonic reducer and planetary reducer have the characteristics of high efficiency, high precision, high load capacity, anti-fatigue and high cost performance. In some industries, the precision gear reduction method of the mechanical arm reducer is used to increase the output torque, the gear precision level, and the flexible clearance adjustment mechanism, which controls the backlash by changing the center distance of the two gears, making the hollow rotating platform empty. The return is small, and the repeated positioning accuracy is high.
The harmonic reducer is a power transmission mechanism, which uses the speed converter of the gear to reduce the number of revolutions of the motor to the required number of revolutions, and obtains a large torque mechanism. The china harmonic reducer can be used in mining, metallurgy, petroleum, chemical, rubber and plastic, construction, building materials, lifting and other industries.
Change the output speed of the power machine to suit the work needs of the working mechanism;
Change the torque output by the power machine to meet the requirements of the working mechanism;
Transform the movement form output by the power machine into the movement form required by the working mechanism.
Transfer the mechanical energy of one power machine to several working mechanisms, or transfer the mechanical energy of several power machines to one working mechanism.
Other special functions such as the use of mechanical reducer devices are beneficial to the assembly, installation, maintenance and safety of the machine.
Robotic arms are used in factory workshops, such as injection molding workshops, automobile manufacturing, electronic manufacturing production lines, logistics supply chains, etc. At present, robotic arm reducers have been in their infancy. With the popularization of intelligent robots and industrial robots, the performance of robotic arms Getting better and better; a series of reducers such as harmonic reducers have become a development trend.
