There are two main types of reducers used in the field of robotics: NMRV worm gear reducers and harmonic reducers. In articulated robots, due to the higher stiffness and rotational accuracy of RNMRV worm gear reducers, NMRV worm gear reducers are generally placed in positions with heavy loads such as the machine base, boom, and shoulders, while harmonic reducers are placed in the forearm, wrist, or hand.

In modern industry, the gearbox, as a key transmission component of mechanical equipment, plays a role in transmitting torque and adjusting speed between the power source and the execution system. Compared with the execution system, the transmission key components can be diversified. With the intelligence of mechanical equipment, the types of reducers are also increasing. At present, precision planetary gearboxes have become the core components of high-end equipment such as industrial robots and automation equipment. Let Liming Machinery Group take you to learn about the relevant knowledge of precision planetary gearboxes.

In the reducer family, the planetary reducer is widely used in the drive system of servo, stepping, DC brushless and other control motors (hereinafter referred to as drive motors) because of its small size (basically the same diameter as the motor), high transmission efficiency (85~90%), wide deceleration range (1:3~100), high precision (small return difference) and many other advantages. On the premise of ensuring precision transmission, it is possible to reduce the speed, increase the torque, and reduce the ratio of load to the rotational inertia of the driving motor. However, in practical use, faults often occur due to improper installation, and shaft breakage of reducers and drive motors is one of the main types of faults. The analysis of the mechanism of shaft breakage is beneficial for customers to understand how to correctly install planetary gearboxes and better utilize their functions.

Secondly, during the process of acceleration and deceleration, if the instantaneous impact torque borne by the output shaft of the gearbox exceeds twice its rated output torque, and this acceleration and deceleration are too frequent, it will ultimately cause the gearbox to break. If such a situation occurs, careful calculation and consideration should be given to increasing the torque margin.
