In the field of modern industrial precision manufacturing, high-speed electric spindle bearings play a pivotal role. Especially in the operation of high-end industrial robots, collaborative robots and special robots, their performance is directly related to the robot’s work efficiency and precision.
Bearing cage is a key component to ensure the normal operation of the bearing. It can accurately maintain the position of the rolling element, evenly distribute the load, effectively reduce friction, and provide smooth rotational motion. In high-speed bearings, the material selection of the cage is particularly critical. Although metal cages have high strength, they are heavy and will generate large inertial forces when rotating at high speeds, thereby increasing friction and heat generation. PEEK cages have the advantages of light weight and corrosion resistance, but their performance still has certain limitations under some extreme working conditions.
Polyimide cages present unique performance advantages.
1. Polyimide materials have excellent high temperature resistance and can maintain stable physical properties under high temperature environments. High-speed electric spindle bearings using polyimide cages can continue to operate stably under high temperature conditions, and will not deform the cage or degrade performance due to temperature increases.
2. The polyimide cage is lightweight, which is crucial for high-speed rotating bearings. It can significantly reduce inertial force, reduce friction and heat generation, and increase the speed limit of the bearing, fully meeting the use requirements of high-end industrial robots and special robots in high-speed operation.
3. Polyimide materials also have good mechanical strength and wear resistance, can withstand certain impact and wear, extend the service life of bearings, and ensure the reliability of robots in long-term work.
In the field of high-end industrial robots, taking the precision machining of automotive parts as an example, robots need to ensure machining accuracy while running at high speed. High-speed electric spindle bearings with polyimide cages can effectively reduce vibration and noise, and significantly improve machining stability and surface quality. When collaborative robots perform fine assembly tasks, the accuracy and stability of bearings are extremely high. The characteristics of polyimide cages can ensure the precise movement of the end effector of collaborative robots and successfully complete high-precision assembly operations. For special robots, such as operating robots in the aerospace field, they often face complex working environments and strict performance requirements. High-speed electric spindle bearings with polyimide cages can adapt well to these special working conditions and ensure the normal operation of robots with their excellent comprehensive performance.
