Cross roller bearing is a special type of bearing with inner ring segmentation and outer ring rotation. Due to the segmented inner or outer rings being fixed together with the cross roller collar after installing the rollers and spacers to prevent separation, the installation of the cross roller collar is simple. Because the cross roller bearing is a structure with an inner ring and an outer ring divided into two parts, the bearing clearance can be adjusted, and even if preloaded, it can rotate with high precision. Due to its special architecture, it is generally used in joint bearings for industrial robots. Today, let's talk about cross roller bearings. Let's take a look together!
There are two main types of bearings commonly used in industrial robots: equal section thin-walled bearings and cross roller bearings. Bearings for industrial robots are one of their key components, suitable for joint or rotating parts of industrial robots, rotating workbenches of machining centers, rotating parts of robotic arms, precision rotating workbenches, medical instruments, measuring instruments, IC manufacturing devices, and other widely used applications.
Advantages of using cross roller bearings for robots:
1. Has excellent rotational accuracy
The internal structure of the cross roller bearing adopts rollers arranged in a 90 "perpendicular cross arrangement, with spacers or isolation blocks installed between the rollers to prevent tilting or friction between the rollers, effectively preventing an increase in rotational torque. In addition, there will be no contact or locking phenomenon between the rollers. At the same time, because the inner and outer rings are segmented structures, the gap can be adjusted, and even if preloading is applied, high-precision rotational motion can be obtained.
2. Simplified operation and installation
The outer or inner ring, which is divided into two parts, is fixed together after the rollers and retainers are installed, so the installation process is very simple.
3. Endure significant axial and radial loads
Because the roller is at 90 degrees. The V-shaped groove rolling surface is arranged perpendicular to each other through spacing retainers, which enables the cross roller bearing to withstand large radial loads, axial loads, and torque loads in all directions. 14. Significantly save installation space
The inner and outer ring dimensions of cross roller bearings are minimized, especially the ultra-thin structure, which is a small size close to the limit and has high rigidity. Therefore, it is suitable for a wide range of applications such as joint or rotating parts of industrial robots, rotating workbenches of machining centers, rotating parts of robotic arms, precision rotating workbenches, medical instruments, measuring instruments, IC manufacturing devices, etc.
The above is all about the advantages of cross roller bearings for industrial robots. In general, cross roller bearings are a very suitable type of bearing for industrial robots, which can make the joints of industrial robots more flexible, and it has excellent rotational accuracy. It is also very simple to operate, and the bearing can bear large axial and radial loads, and can greatly save installation space. Today's sharing is about these.
