For industrial robots, what are the benefits of crossed roller bearings?
Crossed roller bearings are unique in that they have a divided inner ring and a revolving outer ring. Because the divided inner ring or outer ring is mounted with rollers and spacers and is fixed with the cross roller ring to prevent separation from each other, the cross roller ring is simple to install. The bearing clearance may be modified because the cross roller bearing is made up of two parts: an inner ring and an outer ring. It can spin with great accuracy even when preload is applied. It is commonly used for industrial robot joint bearings due to its unique construction.
Constant-section thin-wall bearings and cross-roller bearings are the two major types of bearings utilized in industrial robots. The bearing of an industrial robot is one of its most important components, and it is suitable for the industrial robot's joint or rotating part, the machining center's rotating table, the manipulator's rotating part, the precision rotating table, medical instruments, measuring instruments, IC manufacturing devices, and so on. It is widely utilized.
Cross roller bearing
Crossed roller bearings have the following advantages for robots:
1. Extremely precise rotation
The rollers are positioned in a 90° vertical crosswise configuration with each other on the inside of the crossed roller bearing. Between the rollers, spacers or spacers are put to prevent the rollers from tilting and the rollers from watching each other, thereby preventing the rotating torque. The rise in price. Furthermore, on one side of the roller, there is no contact or locking phenomena; at the same time, because the inner and outer rings are split constructions, the gap can be changed, and high-precision rotational movement can be produced even when preload is applied.
2. Installation and operation are simplified
After the rollers and cages have been mounted, they are connected together, making the installation relatively straightforward.
3. withstand greater axial and radial loads:
The crossing roller bearing can handle bigger radial loads, axial loads, moment loads, and other loads because the rollers are positioned perpendicular to each other on the 90° V-groove rolling surface through spacers.
4, significantly reduce the amount of area required for installation
The inner and outer rings of the crossed roller bearing have been miniaturized to a small size limit, and the ultra-thin structure is close to the small size limit, with high rigidity, making it suitable for the joint or rotating part of industrial robots, as well as the rotating work of machining centers. Tables, rotating sections of manipulators, precision rotating tables, medical devices, measurement instruments, and IC production equipment are only few of the applications.
The advantages of crossed roller bearings for industrial robots are summarized above. In general, crossing roller bearings are an excellent form of bearing for industrial robots because they can make the joints of industrial robots more flexible, have excellent rotation precision, are simple to operate, can carry huge axial and radial loads, and can save a lot of installation space.
