Multi-joint robot and precision reducer RV – robot field (1)

As we all know, with the increase of labor costs and the development of technology, there are more and more applications of industrial robots. There are many types of industrial robots, such as multi-joint robots, plane multi-joint robots, coordinate robots, cylindrical coordinate robots, parallel robots, and factory logistics robots. Among them, multi-joint robots are the most widely used. Multi-joint robots are mainly driven by joint motors, and for the consideration of driving torque, a deceleration mechanism is generally required. Commonly used reduction mechanisms on joint robots include harmonic reducers and RV reducers.As one of the key core components, Nabtesco’s precision reducer

Multi-joint robots are mainly driven by joint motors, and for the consideration of driving torque, a deceleration mechanism is generally required. Commonly used reduction mechanisms on joint robots include harmonic reducers and RV reducers. As one of the key core components, Nabtesco’s precision reducer RV has always occupied a large proportion in the reducer market. Today, this article will talk about this topic.

Articulated industrial robots are very versatile because they can place end-of-arm tools on any plane at almost any angle. In welding, for example, using a multi-joint robot is more continuous and repeatable than using manual techniques. When the workpiece is in a fixed position, the end of the robot arm can precisely determine the optimal distance, angle and speed. Even if the workpiece is not perpendicular to the robot base, the robot can use 3D lasers and machine vision for precise, repeatable inspections. Other applications for articulated robots include painting, pick and place, material handling, packaging and assembly.

For the purchase of reducers for joint parts of multi-joint robots, Nabtesco’s precision reducer RV has always been favored. Mainly because of its large speed ratio, high efficiency, high precision and small size. Compared with other reducers, the precision reducer RV greatly improves the accuracy due to its structural characteristics of less than 1 arc minute of backlash and a large number of gears and pin teeth meshing at the same time. In addition, due to its built-in angular contact ball bearing and the structural characteristics of the double-column support mechanism, it improves its ability to support external loads and has a more compact structure, so that the volume is smaller under the same torque demand. These two points are very important for the selection of the reducer of the multi-axis industrial robot.
