Under the control of program motors, industrial robots can complete operations such as collaboration, handling, and assembly. This process is inseparable from the cooperation of precision bearings. Industrial robot bearings cannot be selected blindly. Only bearings of specific types of designs can meet the needs of robots. So what are the characteristics of industrial robot bearings?
1. High precision
Industrial robots must achieve high-precision motion control, so the bearing rotation accuracy requirements are very high, especially the bearings used in robot joints. The accuracy level is directly related to the positioning accuracy and repeatability of the entire robot.
2. High rigidity
Industrial robots have to face many complex working conditions and bear multi-dimensional loads in different directions such as axial, radial, and overturning moments. Therefore, the rigidity of the bearing must reach a certain level to ensure that it can still maintain high-precision movement under various load conditions and reduce mechanical deformation.
3. Low friction noise
Industrial robots must maintain smooth and efficient movement on the production line, and the bearing friction must be as low as possible. This can reduce energy consumption, reduce heating problems, extend the service life of the robot, and improve overall performance. At the same time, low bearing friction can also reduce abnormal noise and improve the comfort of the robot's operating environment.
4. Miniaturization and Lightweight
In terms of design, the installation space of bearings in industrial robots is relatively limited, so the robot bearings must be designed to be miniaturized and lightweight to meet the compact requirements of robot design, improve the flexibility of the robot and reduce energy consumption.
5. High load-bearing capacity
Industrial robots need to handle large loads in a relatively small space, especially the end effector of the robot arm, which needs to bear a large load. Therefore, the bearings must not only be miniaturized but also have a high load-bearing capacity to withstand large loads.
6. Anti-vibration and high stability
Industrial robots are prone to vibration shock when moving at high speed. Bearings must have good anti-vibration ability to maintain a stable movement state, otherwise the movement accuracy will decrease, the service life of the robot will be reduced, and it will be detrimental to the cost control of the enterprise.
7. Long service life
Industrial robots need to replace manual labor to complete a series of complex tasks, and are often in a state of continuous work. The service life and reliability of the selected bearings are crucial. High-quality bearings can effectively reduce the frequency of maintenance and replacement, allowing the robot to operate stably for a long time.
Industrial robots have relatively high requirements for operating conditions, and the selected bearings must also have the characteristics of high load, high speed, low noise, and durability, so that the industrial robots can continue to operate efficiently.
