Crossed roller bearings are used in high-precision industrial robot arms and precision machine tools. The equipment has high requirements on bearing accuracy. Luoyang Presun Precision Bearings focuses on the development of high-precision crossed roller bearings above P5. In the processing of such bearings, in addition to parts In addition to the dimensional accuracy needs to meet the requirements, bearing assembly is also very important
The internal structure of the crossed roller bearing adopts the rollers arranged perpendicular to each other at 90°, and the spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers and prevent the rollers from grinding each other, and prevent the rotation torque. increase. In addition, the square contact phenomenon or locking phenomenon of the rollers will not occur;
At the same time, because the inner and outer rings are divided structures, the gap can be adjusted, and even if a preload is applied, high-precision rotational motion can be obtained.
The outer ring or inner ring divided into two parts is fastened after the rollers and cages are installed, so the installation operation is very simple.
Because the rollers are arranged perpendicular to each other on the 90° V-groove rolling surface through spacers, this design enables the crossed roller bearing to withstand large radial loads, axial loads and moment loads. direction load.
The size of the inner and outer rings of the crossed roller bearing is minimized, especially the ultra-thin structure is a small size close to the limit, and has high rigidity, so it is suitable for the joint parts or rotating parts of industrial robots, and the rotation work of machining centers It is widely used in tables, manipulator rotating parts, precision rotary tables, medical instruments, measuring instruments, IC manufacturing equipment, etc.
