A Large Model Of Nabtesco RV Reducer With High Precision And High Torque

In order to increase the torque, the parts that make up the Nabtesco RV Reducer need to be larger, so the Nabtesco RV Reducer body will be larger. Large parts are difficult to carry out high-precision processing, so the accuracy of the reducer will inevitably decline. Therefore, it is very difficult to maintain the accuracy of a high-torque reducer.

However, the RV™ series of precision reducers can achieve backlash of less than 1 arc-minute even in large models, and can withstand five times rated torque, with the allowable torque during normal start-stop operations reaching 2.5 times the rated torque, thus balancing high torque and high precision.

In intelligent manufacturing plants, there are many application scenarios that require both high torque and high precision.

For example, the base (1 axis) of a multi-joint industrial robot that can carry heavy objects. Because the equipment is cantilever construction, it is required to withstand large loads. Because the weight of the manipulator will cause the accumulation of displacement error and clearance of the connecting parts of the machine, the position deviation of various parts will be expanded, which will affect the accuracy of the front end unit of the manipulator.

Therefore, the performance of the Nabtesco RV Reducer must take into account "high torque that can rotate smoothly even with large loads" and "high precision with small gaps of each connecting part" to meet the requirements of the base (1 axis) of the multi-joint industrial robot that can carry heavy objects. At the same time, in order to support the load of the mechanical arm, there is also a higher demand for the structural rigidity of the reducer.

The higher the accuracy of the robot, the higher the positioning accuracy of the turntable and positioner that work with it need to be In addition, when large equipment originally driven by hydraulics needs to be converted to electric drive (driven by servo motors), it is also suitable to large Nabtesco RV Reducer.

Nabtesco RV Reducer use a two-stage reduction mechanism, which can achieve a large reduction ratio of over 1/100. The large reduction ratio can match a smaller power servo motor to drive, and also save energy.

The large reducers of Nabtesco RV Reducer are divided solid/empty structures, shaft output/flange output types, which can meet the needs of different customers. In scenes such as robot heavy object handling, heavy loader, and the driving part of opening and closing cover devices, they achieve high-precision control of large-volume and heavy equipment.
